For prevention of air venting of ammonia while blowing it was used catching by acid with sality of ammonium.The results of laboratory researches and experiments which carried out on the experimental installation under real conditions of filtrate purification have shown, that before a stage of the reverse osmosis the mechanical filtration, for example, sand filter, micro- and nanofiltration is expedient to use. The microfiltration under the given conditions is more effective in a mode of cross streams. Application of nanofiltration to give an opportunity of additional extraction a part of soluble pollution and considerably to reduce osmotic pressure. Combination of the reverse osmosis and the electrodialysis allows to purificate a filtrate up to flow rate on water yield in the sewerage system and to considerably increase of a salt concentration for their successful further utilization. For extraction of a carbonate of calcium it is expedient to use a method of reagent sedimentation. Product Description popup.authors popup.nrat_date 2020-04-02 Close
