Relying on professional engineering technology platforms and leveraging the advantages of engineering project procurement channels, we provide high-quality operating consumables, chemicals, and spare parts for water treatment plants/stations in production workshops of domestic and foreign enterprises, helping our sister enterprises reduce costs and increase efficiency. Including DuPont membrane (formerly Dow) (reverse osmosis, nanofiltration, and ultrafiltration membrane products), Dongli membrane (reverse osmosis, nanofiltration, and ultrafiltration membrane products), Grundfos water pump (Zhejiang regional agent, national spare parts supply), PWT agent (11 times concentrated scale inhibitor and non oxidizing bactericide for membrane), and filter element (microfiltration filter element made of PP, PES, PS and other materials). We provide customized membrane products for Nantong Xingchen PPE wastewater concentration device. After small-scale, pilot and on-site trials, the water production effect is good, meeting the requirements of use and effectively reducing membrane replacement costs.
