    REMOVABLE MODULE AND SYSTEM OF REMOVABLE MODULES FOR THE TREATMENT OF WASTEWATER
    FIELD OF THE INVENTION
    The present invention is part of the technical field corresponding to the urban, agricultural and industrial wastewater treatment sector. More specifically, the invention relates, albeit without limitation, to purification of wastewater generated in small urban centers, or in isolated locations.
    BACKGROUND OF THE INVENTION
    Within the technical scope of urban, agricultural and industrial wastewater treatment, it is usual to provide wastewater treatment systems with pre-treatment infrastructures, where preliminary stages of water sanitation are carried out that contain considerable amounts of coarse , suspended solids and floating substances. A pre-treatment system is especially advantageous in the case of isolated industrial sites, agricultural and livestock farms or the majority of small urban agglomerations that do not have a separate water network and where sewage treatment plants have to admit stormwater loading.
    Said pre-treatment systems typically consist of a phase of filtering and purification of water of the type: roughing, sanding, oil and grease separators or equivalent function technologies. In most cases, pretreatment systems include different compartments, modules or tanks in succession and a downstream distribution for harnessing the force of gravity as a source of energy and thus transporting water from one compartment to another contiguous. Some wastewater treatment systems of this type are described in patent applications WO 2012/163308 A2 and FR 2889518 B1.
    At present, roughing systems, sedimentation channels or desanders and degreasers-decanters are usually constructed in the form of a concrete case or channel or other materials, or as compact systems of plastic materials. The

    roughing modules, sand blasters and decanters in many cases have to be emptied periodically manually, and an operator must be introduced in the installation for this. In the case of degreasing-decanter modules, depending on their dimensions, they are usually cleaned of floating substances manually or with automated devices such as suction devices. In both cases it is required that specialized personnel either come into contact with the substances or wastewater, or directly must be introduced into the module for proper maintenance.
    As an alternative to these cleaning situations, for example, industrial wastewater treatment plants have been devised, such as the one disclosed in patent application WO 2012/163308 A2, which are designed to be part of the maintenance and cleaning work They are carried out by means of purging by means of hoppers located at the bottom of the tanks, connected to solid evacuation routes. However, although part of the evacuation of accumulated waste in the compartments can be done in this way, these plants are designed so that an operator enters into each tank to perform repairs or maintenance and cleaning maneuvers.
    On other occasions, as in the domestic wastewater processing system disclosed in the patent application FR 2889518 B1, which includes compartments arranged in a casket, the cleaning of the same occurs by drainage or directly replacing the means of processing and equipment of these compartments, especially when they are saturated with pollutants. In this case, a manual intervention is also required for the maintenance and cleaning of the compartments.
    Additionally, although the known wastewater pre-treatment systems allow to solve certain cleaning and maintenance needs, they are not yet exempt from the technical problem of providing a pre-treatment system suitable to be adapted to all types of treatment plants, including small treatment plants; and whose maintenance can be performed easily, quickly and cleanly by non-specialized personnel.
    With the limitations described in the previous paragraphs it is necessary, in the present technical field, to provide a wastewater treatment or pre-treatment system, whose efficiency in cleaning and maintenance improves the solutions known in the state of the art. On the other hand, it is required at the same time as the system

    offer substantial advantages in terms of sustainability and economic competitiveness, especially important in the purification of wastewater from small towns or small facilities where limited economic resources make it difficult to implement and maintain water sanitation infrastructures, while enabling maintenance be carried out by non-specialized personnel in an easy, fast and clean way.
    For this purpose, the present invention thus proposes a wastewater treatment system devised, although not limited, for its implementation in sewage treatment plants of small towns or small installations, whose technical implementation allows to overcome the problems detailed above.
    BRIEF DESCRIPTION OF THE INVENTION
    An object of the present invention refers, although without limitation, to the development of a wastewater treatment module, suitable for housing in a casket of a purification system, wherein said module comprises:
    - a main space for water accommodation by filling;
    - an overflow that allows water to escape from the module, reaching a certain level of filling of its main space;
    - water treatment means of roughing, decanting and / or separation of materials.
    Advantageously, said module is removable from the space defined by the case, and comprises hooking elements for carrying out its removal from the case where it is housed, so that its emptying, cleaning and maintenance can be carried out quickly and more simple than in the systems known in the state of the art.
    In a preferred embodiment of the invention, the module further comprises one or more support elements for its support in an auxiliary support structure for its dump and / or emptying. This allows maintenance and / or cleaning operations to be carried out without the need for manual intervention. This situation is especially advantageous, for example if the substances inside the module are toxic.

    Another object of the invention relates to a wastewater treatment system comprising two or more modules according to any of the embodiments described herein, and at least one connection between the modules through one or more of the overflows.
    In a preferred embodiment of the invention, the connections of said overflows follow a downstream distribution along the modules. This achieves the use of the force of gravity for the distribution of water through two or more modules for purification in stages.
    In a preferred embodiment of the invention, the system comprises at least one roughing module. More preferably, said system roughing module comprises a filter grid of residual water particles. This is achieved by separating the coarse particles from the wastewater and at the same time this roughing module serves as the first sediment decanter.
    In a preferred embodiment of the invention, the wastewater treatment system comprises at least one settling module, where the bottom of the module itself is the means of water purification, through the force of gravity.
    In a preferred embodiment of the invention, the wastewater treatment system comprises at least one material separation module.
    In a preferred embodiment of the invention, the material separation module comprises at least one fat separating partition that extends from the top to a certain depth of said module, such that it does not reach

    connect to the bottom of it, to retain floating materials and give way to filtered water below said partition.
    Another object of the present invention relates to a wastewater treatment plant comprising a wastewater treatment module or a wastewater treatment system according to any of the embodiments described herein.
    The invention thus allows to propose a solution for pre-treatment of wastewater through a module, system or water treatment plant whose dimensions are perfectly scalable to adapt it to the needs of any case by expanding the size of the modules and / or by increasing the number of modules of each type arranged in series. The invention enables the extraction of the modules and, preferably, the pouring of their contents on an adjoining surface, container or means of transport. This allows maintenance of these modules in a clean, fast and adapted to the needs of the site. This ensures that the operator in charge of maintenance must not come into contact with the substances to be treated or physically enter the infrastructure for such maintenance. The invention is especially functional and suitable for small treatment plants whose managers wish to carry out an operation with their own non-specialized personnel in a sustainable way.
    In this document, the term "treatment" will be used generically to designate, interchangeably, both the wastewater treatment operations performed by the system of the invention, and the pre-treatment operations, where said system is responsible for carrying perform one or more stages prior to other subsequent stages performed by additional treatment systems. The modules and the system of the invention are also of preferred application for the treatment of rainwater or sewage, or for the treatment of industrial water.

    A main object of the invention relates, as described in the preceding sections, and as represented in Figures 1 and 2 of this document, to a wastewater treatment system that preferably comprises a set of treatment modules (1a, 1b, 1c, 1d, 1e), where the different phases of filtering and purification of water are carried out through purification and treatment means arranged for this purpose, preferably being a system with a modular distribution “water down". The modules (1a, 1b, 1c, 1d, 1e) are partially open to enable water flow. In each module (1a, 1b, 1c, 1d, 1e) there are arranged: an overflow (2), a plurality of coupling elements (3) and support elements (4).
    The overflows (2) of the modules (1a, 1b, 1c, 1d, 1e) allow the water outlet of the module (1a, 1b, 1c, 1d, 1e), reached a certain level of filling of its main accommodation space (12) (Figure 1), said main space (12) being understood as the volume destined to receive the water to be treated in each module (1a, 1b, 1c, 1d, 1e). The overflows (2) can, in a preferred embodiment of the invention, be arranged in the form of connecting tabs (Figure 2) that allow the coupling between two or more modules (1a, 1b, 1c, 1d, 1e) adjacent to the system.
    The hooking elements (3) are arranged in each module (1a, 1b, 1c, 1d, 1e) for removal, for example through an auxiliary lifting or hoisting system, such as a crane, boom, hoist, etc. .
    The support elements (4) allow, after removal of the module (1a, 1b, 1c, 1d, 1e), it can be supported by an auxiliary support structure (11), so that the module (1a, 1b, 1c , 1d, 1e) can, for example, tip over, allowing emptying and cleaning (Fig. 3).
    The system also comprises a casket (5) where the modules (1a, 1b, 1c, 1d, 1e) are arranged and has two holes (6, 7) for the passage of water, one for inlet (6) and the other for output (7) as seen in Figure 1.
    In a preferred embodiment of the invention and as shown in Figures 1 and 2, the system includes three types of modules (1a, 1b, 1c, 1d, 1e) with different treatment functions, opened at the top, which are placed in series to be traversed by the wastewater by overflowing from one module (1a, 1b, 1c, 1d, 1e) to the next. In a preferred embodiment of the invention, each module (1a, 1b, 1c, 1d, 1e) has three walls of greater height and a fourth wall, adjacent to the next module (1a, 1b, 1c, 1d,
    5

    1e), of a height smaller than the others and equipped with an overflow (2) designed in such a way that a treatment module (1a) is interconnected with another adjacent module (1b), successively. The last module (1e) connects to the outlet hole (7) of the box (5), to transfer the wastewater allowing a distribution of “downstream”.
    The system preferably comprises and in accordance with Figure 1, a roughing module (1a), two decanting modules (1b, 1c), two separating modules (1d, 1e) of fats and oils.
    In this preferred embodiment, the first roughing module (1a) is provided with a grid (8), according to the needs, which separates the coarse particles from the wastewater and at the same time serves as the first sediment decanter.
    The intermediate modules are two decantation modules (1b, 1c), whose function is to enhance the decantation / sedimentation of gravels, sand and other sediments thanks to the minimization effect of the water velocity exerted by its walls.
    The final modules are two separator modules (1d, 1e) of oils and greases each equipped with two interior partitions (9,10) that go from wall to wall, arranged transversely to the direction of water circulation. In a preferred embodiment of the invention, a first lower partition (9) extends from the bottom of the container to, substantially, 3/4 of the height of the container, promoting the decantation of particles of greater density than water, at the bottom of a first compartment and forcing water to circulate at the top (Fig. 1). The second upper partition (10) extends from the top to a depth of approximately 1/4 of the height of the sheet of water measured from the bottom, being responsible for retaining the oils, fats and foams that will remain floating at the top and forcing the water to go through the free hole in the bottom to go back up after the partition (10) to the overflow (2) that gives way to the water to the next oil separator module (1e) and fats, where the same process described above takes place. Finally, from this final separator module (1e) the water overflows to the outlet port (7) of the pre-treatment system.
    Figure 3 schematically represents the dump / drain stage after removal and removal of the module (1a, 1b, 1c, 1d, 1e) of treatment proposed for this preferred embodiment of the invention. In this situation, the coupling elements (3) serve to,
    Using a crane or other mechanism, connect the module (1a, 1b, 1c, 1d, 1e) to the crane and remove the module (1a, 1b, 1c, 1d, 1e) provided in the box (5) for deposition in an auxiliary clamping structure (11) that allows the dump, emptying and cleaning of the module (1a, 1b, 1c, 1d, 1e). In this case, the support elements (4) serve to make said support on the auxiliary support structure (11).
    Alternatively, the dimensions of the system are perfectly scalable to suit the needs of any case by extending the size of the modules (1a, 1b, 1c, 1d, 1e). Alternatively, the system may comprise more than 10 modules (1a, 1b, 1c, 1d, 1e) or a smaller number of modules (1a, 1b, 1c, 1d, 1e), as shown in Figure 2.
    Optionally, other means of purification and filtering of water can be implanted in the modules (1a, 1b, 1c, 1d, 1e) of the system.
