FR2880014A1 - Water treatment unit for reducing chloramines in public swimming pool water comprises modules fitted with germicidal lamps and/or mechanical cleaning system - Google Patents

Abstract

The treatment unit consists of a modular treatment chamber with an inlet (1) and an outlet (11) for the treated water and one or more modules (2, 2 bis), each with holders (12) for germicidal lamps and/or a mechanical cleaning system. Each of the lamps is insulated by a quartz sleeve to form a UV generator: the modules have points (7) to receive accessories such as temperature sensors (8), monitoring instrumentation (9) or purging valves (10), and a number of modules can be assembled by means of flanges (3) to make up a treatment unit. The components of the unit are made e.g. from stainless steel 316L with electrolytically treated internal and external surfaces.

Description

The present invention is based on the modularity of a system of

  treatment of bathing water, used in public swimming pools by UV process.

  This modularity concerns both the number of modules, the type of UV generator group per module, and the type and number of accessories per module.

  This treatment system, intended to reduce chloramines, uses ultraviolet water treatment technology, the range of which extends over type C wavelengths from 200 to 280 nm.

  In fact, ultraviolet radiation actions on swimming pool water, based on photolysis and disinfection, make it possible to reduce the level of chloramines in public basins.

  The device according to the invention thus consists of modules making it possible to construct a treatment system whose sizing characteristics are easily and inexpensively adapted to the different volumes of pool pools.

  The modularity of the device, object of the present invention, has the following advantages: - Possibility of adapting to the best treatment of existing basins, this by associating one or more modules.

  - Ease and speed of extension of the treatment without modifying the original installation bases, the construction of an additional basin, or the increase of the frequentation of the basins (IMF) which could be at the origin of this need for 'extension.

  Easy and fast to add processing accessories such as mechanical cleaning system (13), control instrumentation (UV cell, flow management, drain purge, ...) Very strong economic interest because the extension is limited to the addition of one or more modules, one or more accessories, and not the addition of one or more complete treatment systems.

  The accompanying drawings illustrate the invention: FIG. 1 represents a side view of the device of the invention.

  - Figure 2 shows a top view of the device of the invention.

  With reference to these drawings, the device comprises an element managing the fluid inlet (1), one or more modules (2), (2bis), ... assembling together by means of flanges ( 3).

  Each module comprises three receptacles (12) which integrate a UV generator group (4), (4a), ...

  This UV generator group comprises one or more germicidal lamps (5) type UVc, low or medium pressure design, mono or bi-base. These lamps are isolated from the fluid via a quartz sheath (6), which allows optional ventilation.

  Each module also has three expectations (7) for receiving, according to the needs of the site, accessories to the treatment system, of the temperature sensor type (8), control instrumentation (9), purge (10) ...

  A complementary element manages the fluid outlet (11) The elements (1), (2), (2bis) and (11), forming the treatment chamber, are of 316L stainless steel construction, and have undergone internal surface treatment and external electrolytic type.

  This device is powered by an electrical control and control cabinet 5 for servoing the UV generators.

  According to non-illustrated variants, the modules may comprise receptacles and expectations in variable quantities According to non-illustrated variants, other geometric shapes (round section, polygonal) may be integrated for the elements (1), (2), (2bis) and (11).

Claims (3)

  1) Device for reducing chloramines in bathing water characterized in that it comprises a modular treatment chamber, composed of an element managing the fluid inlet (1), a module (2), or several modules (2), (2a), ... and an element managing the fluid outlet (11) Each module comprises receptacles (12) integrating as required one or more germicidal lamps (5), and / or a mechanical cleaning system (13).   Each lamp is insulated by a quartz sheath (6), the set of germicidal lamps and quartz sheaths forming the UV generator group (4) or (4a) of the module.   2) Device according to claim 1 characterized in that it comprises one or more modules (2), (2a), ..., joined to each other by means of flanges (3), to form the group module (14).   3) Device according to claims 1 and 2 characterized in that each module comprises expectations (7) for receiving, as needed and on demand, accessories to the processing system of the temperature sensor type (8), instrumentation of control (9), purge (10).
