Project implementation effect
Up to now, the desalination rate of the system still exceeds 96%. The scale inhibitor of Shandong Dahu New Material Co., Ltd. effectively reduces the risk of system scaling and fouling, reduces the cleaning times, ensures that the membrane system has a high desalination rate, reduces the regeneration times for the subsequent ion exchange process, and realizes the dual effects of reducing labor intensity and saving cost.
