    lO1520253035a certain time, depending on the composition of the well waternet, the pool water becomes discolored so that it turns blue,green, brown, maroon, black or black-brown. Asaction to remove this discoloration suggests orThe pool manufacturers recommend that the water in the poolichock treated with chlorine. Such a chlorine treatment provides, howevernot desired result and is also harmful to boththe human body as nature. Another possibility is thatprovide expensive special filters to remove itdiscoloring material, but due to i.a. priced,10,000-30,000 kronor per special filter, this is notany acceptable solution. Because municipal water has onecomposition other than well water, which does notdyes, it is suggested that the pool be completely or partially filledwith municipal water, e.g. by letting the rescue squadtake care of the filling with the help of a tanker. This one toosolution involves too high costs. The presence of calcareouscompounds in the pool water means that sparingly soluble limedeposits can form on the pool's surfaces and equipment. Notnor is this problem solved with the help of the aboveproposals.
    The object of the invention is to solve the above-mentioned problemsand provide an additive filter to the ordinarythe pool filter, which is cheap and efficient to use forto remove the discoloration and achieve a clearer orclear water within a relatively short time.
    The additive filter according to the invention is characterized by- that the additive filter comprises a plurality of aqueouspermeable, abutting filter layers ofa thin fabric material and is dimensioned and designedto be applied around the existing filter sleeve forto completely enclose the filter sleeve with a main portion, and- that each filter layer has larger openings, wherebysome of the larger openings of the filter layers arealigned with each other in whole or in part for formation101520253035of flow channels for the circulating water,partly smaller openings of varying sizes, such asprevents the passage of the water-discolouring particles,which are distributed within a certain size range,whose upper value forms the limit value for the transition betweensaid larger openings and said smaller openings.
    The method according to the invention is characterized in thatthat the circulation through the circulation loop is stopped andthe existing filter sleeve is removed from the filter housing,that an additive filter, which comprises a pluralitywater-permeable, abutting filterslayer of a thin cloth material, applied around itremoved the filter sleeve to with a main portion completelyenclose the filter sleeve, which filter layers each havepartly larger openings, some of the larger onesthe openings of the filter layers are aligned with each otherwholly or partly for the formation of flow channelssmiles for the circulating water, partly smaller openingsof varying sizes, which prevent the passage of thewater-discolouring particles, which are distributed withina certain size range, the upper value of which formslimit value for the transition between said majoropenings and said smaller openings,that the filter assembly of the existing filter sleeve andthe additive filter is placed in the filter housing,that circulation through the circulation loop thereafter againstarted and allowed to run during a predeterminedperiod,that the circulation is then stopped and saidfilter assembly is removed from the filter housing,that it of water-discoloring particles dirtythe additive filter is removed from the filter sleeve andreplaced with a new, clean additive filter, andthat the procedure as above is repeated as needed untilacceptable clarity obtained.10l520253035Preferably, said predetermined time period is within24i6 hours.
    Preferably the procedure is repeated 3-6 times, morepreferably 4-5 times.
    Preferably, at least a portion of said largeropenings sizes that form said flow-throughchannels to allow a high water permeability sothat the flow rate in said circulation loopminimally affected.
    Preferably, said smaller openings comprise small onesopenings of varying sizes that prevent the passage ofwater-discoloring particles larger than about 30 microns,which particles thereby become attached and retained bythe filter layers.
    Preferably, said limit value is about 600 microns.
    Preferably, the additive filter is designed as a sleeve withend portions, which define opposite end openings, whereinthe filter sleeve is arranged to be inserted through one of theseend openings for forming a filter assembly forplacement in a filter chamber in the filter housing.
    It has surprisingly been found that the additive filteraccording to the invention effectively removesthe discoloration of the pool water and this within relativelyshort time, usually less than 5 days.
    It is not entirely clear what the real thing isthe cause of the discoloration itself. One theory is, thatthe pool water has a relatively large free surface, which is exposedfor the surrounding air, which causes the pool wateroxygenation increases. Also the circulation of pool water throughthe circulation loop contributes to increased oxygenation oflO1520253035the pool water. The metal compounds, which are found in the pool waterafter the pool is filled, it will be oxidized as suchthat various insoluble metal oxides are formed, of whichseveral are strongly staining in water, such as in the first placeiron oxide, copper oxide and manganese oxide. Iron, copper andthe manganese ions originate from the well water and thethe system in varying amounts. Metallic manganese is releasedfrom the metal wires in the wiring system. Respectivemetal oxide forms small colored particles, the amount of which increasesin step with the oxygenation so that the pool water after oneshort-term use acquires a visible color. Color inkthe site increases with time to cease after allmetal compounds initially added have been oxidized.
    In addition, the well water usually contains calciumcompounds which are also oxidized to calcium oxide, whereinparticles of calcium oxide can absorb paint particles ofmentioned metal oxides, which can also contribute to an increasecolor intensity and thus increased degree of discoloration ofthe pool water. Also chlorine ions or other acidic ions, such asderived from bactericides, which are added to the poolwater, may be involved in the chemical reactions thatleads to discoloration.
    The invention will be described in more detail in the followingwith reference to the drawings.
    Figure 1 schematically shows parts of an outdoor pool, whichhas a circulation loop with a pump, which is equipped witha filter housing and a pool filter placed therein.
    Figure 2 is an exploded view of the pump of Figure 1.
    Figures 3 and 4 show an additive filter according tothe invention.101520253035Figures 5 and 6 show the additive filter according to the figures3 and 4 partially and completely enclosing the pool filter, respectivelyaccording to figure 1.
    Figure 1 shows a part of an outdoor pool, which includesa pool 1 and an external circulation loop 2 for purificationof the water in the pool with respect to larger, visible,solid particles. The circulation loop contains a pump 3and an outlet hose 4 and an inlet hose 5.
    The outlet hose 4 is connected to an outlet 6 ofthe pool 1 and an inlet 7 of the pump 3, while the inletthe hose 5 is connected to an outlet 8 of the pump 3 andan inlet 9 of the pool 1. The inlet 7 is located vertically.cold above the outlet 8. Using the pump 3 is suckedwater from the pool 1 to the pump 3 via the drain hose 4and fed back from pump 3 to pool 1 viainlet hose 5. The pump 3 comprises a cylindricalfilter housing 10, the center line of which is vertical, and which islocated vertically above the pump part itself. The filter housing10 has an inner filter chamber 11, which thus also hascylindrical shape and having a central opening (not shown)at its bottom end, which communicates with the pump 3outlet 8 via the spaces delimited by the pump 3shovels (not shown). Furthermore, the filter chamber 11 has aside opening, which connects directly to the inlet 7through the wall of the filter housing 10. During operation is keptthe filter chamber 11 is closed by means of a cylinder head 12, whichscrewed onto the upper end portion of the filter housing 10. In the filterchamber 11 there is a cylindrical pool filter 13 in the form ofa removable pool filter cartridge, the upper end opening 14 of whichduring operation it is kept closed by means of the cylinder head 12so that no water is allowed to pass through this upperend opening 14 from the outside of the pool filter 13, and the lower of whichend opening (not shown) is in direct communication withsaid central opening in the bottom end of the filter chamber 11,against which the pool filter cartridge 13 is in sealing contact.
    The diameter of the pool filter cartridge 13 is slightly smaller than101520253035the diameter of the filter chamber 11 so that one is formedannular, free space between the inside of the filter housing 10and the outside of the filter cartridge 13, whereby water fromthe pool 1 can be distributed around the filter filter cartridge 13part 15 so that the entire filter surface can be used forflow of pool water through the pool filter cartridge 13 toits interior space.
    During the circulation of water, larger, visible,solid particles such as insects, conifers, pollen, small twigsparts, skin parts, etc., to adhere to the filter part 15outside. The filter part 15 is suitably pleated similar to oneaccordion bellows to achieve an increased flow area.
    Figures 3-6 show an additional filter 16 according tothe invention, which is applied to the pool filter 13 if necessary,so that it completely encloses the filter part 15 of the pool filter13. The additive filter 16 is in the form of a sleeve with resistance.end openings 17, 18 with a diameter that is slightlysmaller than the diameter of the pool filter 13 to form pleatedend portions 19, 20, which abut against the pool filter 13end surfaces 21, 22 so that the additive filter 16 at its end portions19, 20 around the end openings 17, 18 are clamped betweenthe pool filter 13 and the top cover 12 and the bottom surface, respectivelythe filter chamber 11. The end portions are provided with elasticband, which enables the end openings 17, 18 to be widenedgas so that the pool filter cartridge 13 can be easily inserted intothe additive filter 16 through one of these end openings 17,18. The additive filter 16 is so dimensioned to the sizeof the pool filter 13 that with a larger filter portion 24,extending between the end portions 19, 20, willabut against the pool filter 13 or be located relativelyclose to this so that a filter assembly 23 of the additive filter16 and the pool filter 13 can be inserted into the filter chamber 11no problem.101520253035The additive filter 16 is made of two or preferablyseveral, air- and water-permeable filter layers of onesoft, non-self-supporting, thin fabric material, such as canconsist of thin, short and / or long, straight and / orcrooked plastic threads or fibers, e.g. polypropylene, whichare connected in a disordered pattern with openingsbetween the threads or fibers of varying size andform. The multilayer additive filter has a high water content.permeability so that the flow rate of the pool water becomesalmost the same as when the additive filter is notmounted on the pool filter 13. Despite this, thelayer the additive filter 16 to catch and holdwater-discolouring insoluble particles of metalprecipitated in the chlorinated water of the pool.
    Each filter layer of the additive filter 16 comprises onefirst group of larger openings, which make sure thatcontinuous flow channels are formed through allfilter layers and a second group of smaller openings, such asensures that the water-discolouring particles stickin the filter layers, these particles being distributed withina size range, where the upper value of the particlesize forms the boundary and transition between said firstgroup of larger openings and other group of smaller onesopenings.
    In an attempt to investigate the effect of the inventionan additive filter 16 was used, which had five separatedfilter layer of a thin cloth material of the one described abovetype, which fabric material had a basis weight of about 20 g / m2.
    The experiment showed that the flow rate decreased withonly 0.1-0.2% after the assembly of the five-layerthe additive filter 16. After 1 day of running the pumpthe additive filter 16, which was found to be, was removeddirty by particles. The additive filter 16 was rinsed cleanwith fresh water. The rinsing water was collected and the procedurewas repeated for another 4 days using onebrand new, clean additive filter of the same type after each10152025303524-hour driving. The rinsing water from the five cleaning flusheswas collected and evaporated to give 2.73 g ofa dry material of particles, which material was sievedand analyzed to determine the distribution ofparticle size. The result was the following:Sight analysisMesh Micron Rest, grams28 600 0.0735 425 0.0545 355 0.0860 250 0.0965 212 1.04200 75 1.15325 43 0.11Bottom 0.14In this case, said upper value of particle size is withinsaid size range thus about 600 microns. Thethe lower value can be estimated at about 30 microns(0.14 g passes openings less than 43 microns).
    During the five days, the discoloration gradually decreased afterevery day. After five days, no discoloration could occurseen with the naked eye. The pool water was thus completely clearand the filtration with the additive filter 16 could ceaseto be resumed only after the pool has later been completely emptiedor partially and subsequently filled to the corresponding degree withfresh water containing metal compounds. The one aboveThe reported sight analysis shows that a larger proportion of itcollected particulate matter was retained on sieves with amesh size of 75 microns or more, namely 2.48 gcorresponding to about 91%, which particles should therefore correspondfor the largest proportion of the discoloration of the pool water.
    Only 5.1%a mesh size of 43 microns. In the said flushing of(0.14 g) passes the last sieve, which has10152025303510the additive filter 16 also flushes the pool filter 13 itselfseparately, before being placed back in the pump. Of thisexperiments show that a larger proportion of those mentioned are smallerthe openings should preferably have a size of about75 microns and below.
    The screened particulate matter was collected and examined.with regard to its chemical composition. Atthe assay used an X-ray fluorescence spectrophotometerwith the designation XRF ARL 9400. The following contents of variouscompounds were noted:Compound Weight%MgO 0.333SiO2 12.51PZO5 0.914Cl 0.581CaO 4.64MnO 28.59Fe2O3 50.87In this experiment, the added pool water did not containany copper compound.
    It is surprising that the multilayer additive filterdoes not significantly reduce the water flow ratewhile the small water-discolouring particles,typically between about 30 and about 600 microns, cancaptured and retained by the canvas layers. A probableexplanation can be the following: When several cloth filterslayer, e.g. 5 pieces, laid against each other come onin some places some of the larger openings, such asthus being over about 600 microns, that in whole or in partoverlap each other and if the overlap is continuousthrough all the filter layers, ie. from the extreme orfirst to the last or innermost filter layer,the overlapping openings form one101520253035llflow channel for water, which thus passesthrough all the filter layers and then the permanent poolthe filter. Of course, some of the water can discolorthe particles accompany this water, which, however, can be trappedin at the next passage or passage of pool water. Oneanother part of the mentioned larger openings comes on othersplaces to completely or partially overlap, but ona limited way so that the channel is blocked by a denserzone of an underlying filter layer, which may bethird, fourth or fifth filter layer. These denserzones of the filter layer have several smaller onesopenings of varying sizes, which are smaller openingsthus is less than about 600 microns, and which frominitially lets water through, but is eventually blockedof particles within the specified size range ofabout 30-600 microns. It is realized that some smallerparticles can pass through openings in the said denserthe zone, which has sizes within the upper part of saidsize range, but which can then get caught in a similar onezone, which may be present in the 4th and / or 5th filterthe layer. What is described above also applies to onelarger opening, ie. over about 600 microns, found inthe first filter layer, but which has no overlapto a larger opening in the second filter layer, as theninstead has a denser zone of the kind described above. Thewater that has passed the additive filter 16 and is re-fedin the pool thus still contains waterparticles, but will get stuck in the additive filterafter one or more additional entriesthe additive filter. A disassembly of an additive filter,which have been in operation for l day shows particle collectionsthe outside of all layers.
    The particle range can vary depending on thesoil conditions, which are in the current area therewater is fetched for the pool. In general, most people can101520253012the particle sizes are in the range around30-600 microns.
    A suitable fabric material is what was used ascovering plant protection during plant cultivation, which fabric materialis air and water permeable and has a basis weight ofabout 20 g / m2. A fabric material can also be producedseparately, showing larger and smaller openings ofspecified type with appropriate area distribution between them inzones to achieve said effects, a larger oneproportion of the smaller openings preferably have onesize of about 75 microns or less. The fabric materialis soft and has a low basis weight, generally suitable around15-40 g / m2. This ensures that the filter layers ofthe fabric material will be pressed against each other and against itpermanent pool filter 13 during operation so that side flowsbetween the filter layers becomes minimal or evenis prevented when the pool water flows into the additional felt16 and through this. This prevents them fromparticles already stuck in a filter layer within adenser zone with the mentioned smaller openings is not jerkedwith some sidestreams but is retained until the additivethe filter 16 is discarded and replaced with an unused oneadditive filter.
