About Us


Since 2014, HID has invested in a full-auto RO membrane flat sheet (composite polyamide) production line, which has passed in-house testing to meet the international main brands’ technical index. By the end of 2016, the second flat sheet line with updated design & automation has been in operation from June, thus making the total flat sheet output to 20000 square meters per day. HID quality flat sheet not only serves the HID RO membrane but to be supplied to other customers worldwide!
