Inorganic Wastewater Treatment

High Selective Chelating Resin for Heavy Metals

Inorganic wastewater mainly refers to many metal ions, which are commonly found in electroplating, hydrometallurgy, and circuit board industries.
For the treatment of metal wastewater,recycling as resources is first to be consider, Such as the value matals; Another is the problem of emission standards, for example, heavy metals content in waste water is required strictly, some even in ppb level.

Our solution is aiming at removing heavy metals,such as Cu, Ni, Cr, Pb, Cd, Co, Mn, Hg, As; Recycling the value metals from wastewater.

In view of the diversity of wastewater, our company will propose different solutions for the specific targets of different wastewaters.

Acetic Acid Purification with Sunresin’s Ion Exchange Resins

Sunresin provides a mature ion exchange resin process for acetic acid purification, which can remove bromine or chloride ions in acetic acid to less than 5ppm, or undetectable levels. The fixed bed mode is recommended for the ion exchange process for acetic acid purification, which runs continuously and removes impurities through the front and back resin columns to improve the removal accuracy and ensure the maximum utilization of the resins. For details, refer to the figure below.
