Groundwater

Waterquality issues:

High levels of ionic contaminants areusually present

Solution：

Adoptdouble membrane process, ultra-filtration membrane as a pretreatment process ofnanofiltration/reverse osmosis, can effectively remove suspended matter,colloid, bacteria, macromolecular organic matter and other harmful substancesin the water, improve the water quality of nanofiltration/reverse osmosis feedwater, and then nanofiltration/reverse osmosis remove high concentration ofionic substances in the water, so that the permeate water quality can reachesthe requirements of high quality discharge
