Printing and dyeing wastewater for pharmaceutical 1, the company specifically for printing and dyeing wastewater treatment independent research and development of high-tech products. The agent can effectively improve the interfacial tension of printing and dyeing wastewater, so that the colloidal particles within the sewage loss of stability and attractive force, and ultimately lose stability and the formation of flocs, and further through the chemical bridge, and ultimately complete the separation of organic matter in the sewage And the separation of harmful impurities, shorten the separation time, can be miscible with water, and in a wide range of pH value.
