Purpose and area of application
The proposed various filtering devices relate, basically, to a category of household filters, which are intended only for additional cleaning of potable water of the centralized water supply. The majority of them can not be used at absence of a water pipe and are not intended for disinfecting water from the polluted natural sources.
For removal from water (well water, river water etc.) mechanical impurities like as sand, the weighed particles, as well as detention of soluble organic and chlorine organic compounds, elimination of unpleasant smells, cleaning from colloid particles with heavy metals, disinfection of microbe pollution were developed and produced the compact portable complete sets, which allow to produce potable water practically from any polluted sources.
Such complete sets are necessary for services of rescue (extreme situations), for militaries, for people working or living at a distance from centralized sources of potable water, as well as in areas with adverse ecological conditions.
Technical characteristics Contents of the filtering complete set:
- portable filter of funnel type,
- package of disinfecting tablets "AQUATABS" (North Ireland)
- quickly dispersed carbon coagulant.

Description of technology
Tablets "AQUATABS" are applied to disinfection of microbe pollution of water.
The developed design of funnel filter is produced from cloth polyester filtering (Spec. 05568283.002-96) and a highly active nonwoven carbon sorbent "Carbopon-ACTIVE" (Spec. 400031189.109-2000), produced in Belarus.
The composition of coagulant was proposed and developed on the base of the powder from activated carbon and new water-soluble polymer, which forms a high dispersed suspension of carbon particles at dissolution in water. The produced suspension of carbon particles coagulates in 5-15 minutes, and the formed feculence with practically all kinds of pollution available in water, is easily filtered on the funnel filter.
There was developed the technology of joint usage of the portable filter, disinfectant "AQUATABS" and carbon coagulant for production of potable water from sources of a various degree of pollution, including sewage. It was shown on tests of water from various natural sources, including sewage, that only the combination of stages of preliminary filtration, disinfecting, coagulation and finishing filtration of water allows to produce "safe" potable water in accordance with all required parameters.
