AERATOR-FILTER FOR WATER objects

The utility model relates to the field of environmental protection and is intended for the simultaneous aeration and filtration of water bodies of water.

Aeration is understood as the process of saturation of water with oxygen. Oxygen dissolved in water plays a major role in the processes of microbiological purification (self-cleaning) of a water body from pollutants. Filtration helps to purify water from suspended solids, as well as from dissolved pollutants using filtration material. Microorganisms settle on the filtration material, which together with the filtration charge (material) create a biofiltration complex.

Known tube aerator (RF Patent No. 2485057, IPC C02F 3/02, publ. 06/20/2013), which relates to a wastewater treatment technique, containing a support pipe with radial holes and an elastic tubular membrane over the support pipe, a clamp at each end of the elastic tubular membrane perforation in an elastic tubular membrane.

The disadvantage of this device is the absence during the operation of the stage of filtration (biofiltration) of water, which significantly reduces the effectiveness of measures to purify water from suspended and dissolved pollutants.

A known aerator (RF Patent No. 2493109, IPC C02F 3/18, published on 09/20/2013) for wastewater treatment, including a dispersing element in the form of a porous pipe, covering the support pipe with a gap. Each end of the porous tube of the dispersing element is hermetically enclosed by a removable annular sleeve having the ability to hold the porous tube coaxially with the support tube. The ring cuff is made of an elastic polymer material or an elastic material. The support pipe has the ability to reciprocate along the annular cuffs, and the ends of the porous pipe have the ability to reciprocate between the annular cuffs.

The disadvantage of the aerator is the absence of a stage of water filtration during its operation, which significantly reduces the effectiveness of measures to purify water from suspended and dissolved pollutants.

The closest in essence is a filter aerator with aseptic properties, which relates to the equipment of water outlets in sanitary fittings (RF Patent No. 131642, IPC B01D35 / 04, published on 08.27.2013), containing a housing, an air supply module and aeration of the water stream, a silver-containing element, for example, in the form of a grate, a metal screen of the coarse filter, a sealing sleeve, a flow separation module, a rubber seal.

The main disadvantage of this device is the inability to use it on natural water bodies with a high content of suspended solids, which will affect the efficiency of the filter (constant pollution of the filter), as well as the absence of a stage of biofiltration of water due to the presence of aseptic properties of the device.

The objective of the utility model is to increase the efficiency of wastewater treatment at a water body by combining the aeration and filtration processes of water from a water body.

The technical result is achieved in that the aerator filter for water bodies contains an air compressor (1), a flexible air hose (2) with an air atomizer (3), an intake pipe (4), which is connected to a floating tank platform (5) containing filtration charge (6), drain hole (7). The floating tank-platform is held in a certain place of the water body by means of an anchor rope (8) connected to the anchor (9).

The essence of the utility model is illustrated by the drawing of FIG. 1, which shows a diagram of a device.

The device is assembled in the following order. On the shore of a water body, a partial assembly of the device is carried out. An intake pipe (4) is attached to the floating container platform (6), to which a flexible air hose (2) with an air atomizer (3) is attached. Next, the floating container platform (6) with the assembled elements (2, 3, 4) is launched, whereupon the air compressor (1) is installed and the flexible air hose (2) is attached to it, filled with a filter load (6), attachment of the anchor rope (8) with the anchor (9).

The operation of the device in assembled form on a water body is as follows. The aerator filter is transported using a small vessel to the place of placement, and the location is fixed with an anchor (9), which holds the device using an anchor rope (8). Next, an air compressor (1) is launched, which, through a flexible air hose (2) through an air atomizer (3), emits air bubbles. Air bubbles rising to the surface of the water along the intake pipe (4) create a stream of water, which, being carried away by the air bubbles, moves to a floating container platform (5). Water passes through the filtration charge (6), and, being purified, is discharged into the water body through the drain hole (7).

The number of installed filter aerators depends on the area of the water body and the required quality of water treatment (level of initial water pollution).

The model of the device is tested in laboratory conditions. The rate of water saturation with oxygen is dependent on the volume of water and the volume of air supplied. The degree of filtration of water from suspended particles (depending on the filtration load) can reach 95-99%. The cleaning efficiency is increased in the presence of microorganisms in the filtration charge (biofiltration).

The technical result of the proposed device is the combination of two processes necessary for effective water treatment - aeration and filtration, which allows to increase the quality of treatment and achieve economic benefits.
