Study of water softening and desalination by nanofiltration at the Taganrog water treatment facilities

Summary

The results of studies on reducing the hardness and salt concentration in water using the nanofiltration method are presented. The tests were carried out under production and laboratory conditions at the water treatment facilities of Taganrog. The results of testing and specifying the process parameters of nanofiltration are given. The data on the change in the cation-anion composition of permeate and concentrate depending on the number of nanofiltration cascades and pretreatment of the raw water with an antiscalant is provided. The results of field tests of softening and partial desalination of water under the conditions of water purification process at the Taganrog water treatment facilities confirmed the high efficiency of single-stage four-cascade nanofiltration.

Key words

concentrate , permeate , water treatment facilities , water hardness and salt concentration , nanofiltration unit , antiscalant
