New domestic polymeric salt-removal inhibitors AMETEK RO-1 and AMETEK RO-2 to prevent the deposition of mineral salts in the desalination and desalination plants of seawater
This publication reviews the results of testing two new domestic scaling inhibitors for membrane filtration plants for desalination and demineralization of highly mineralized (sea) waters AMETEK RO-1 and AMETEK RO-2 under static and dynamic conditions, as on imitates of sea water, and on the Black Sea water. Their high efficiency was established. On the basis of the Evpatoria branch of the State Unitary Enterprise "Water of the Crimea" on the pilot plant, it was shown that the reagent "AMETEK RO-1" for 6 hours (3 series for 2 hours) at a dosage of 5 g/m3 (14 g/m3 per commodity form) provided 91-93% inhibition during desalination of the Black Sea water with the help of nanofiltration and reverse osmosis membranes with a filtrate yield of 40-60% in the first stage and 60-68% in the second stage. At a dosage of 10 g/m3 (28 g/m3 in product form), the AMETEK RO-1 reagent for 4 hours (2 sets of 2 hours each) provided 93-94% inhibition when desalting the Black Sea water with nano-filtration and reverse osmosis membranes at a filtrate outlet of 40-60% in the first stage and 60-69% in the second stage. The AMETEK RO-2 reagent for 4 hours (2 batches of 2 hours) at a dosage of 10 g/m3 provided 90-91% inhibition for desalination of the Black Sea water by means of nanofiltration and reverse osmosis membranes with a filtrate yield of 40-60% at the first step and 60-72% in the second stage.
