Adsorbent Resin for Wastewater Treatment

Lanlang adsorbent resins are prepared by polymerization reaction of additives such as backbone (polymeric monomer), crosslinker, porogenic agent and dispersant. It has a high internal porosity in the dry state and a large pore size between 100 and 1000 nm.

It is generally white beads and is a kind of macroporous polymer adsorption resin without exchange groups. It has a large specific surface area and can selectively adsorb organic matter in aqueous solutions. It is mainly used in the treatment of organic wastewater and the refinement and purification of active ingredients of traditional Chinese medicine.

Macroporous adsorption resins can be divided into non-polar and polar types, depending on the size of the polarity and the structure of the monomer selected. Polarity is further divided into weak polarity, medium polarity and polarity.

Lanlang is the member of American Water Quality Association. In 2016, Lanlang obtained WQA Certification with NSF / ANSI61 and 372 standard. And in 2022, Lanlang obtained NSF Certification with NSF/ANSI44 and 42 standard.
