Find Nano Zeolite 4a, Concentrator Zeolite Drying Solvents, Zeolite Molecular Sieve For Ethanol Distillation on Industry Directory, Reliable Manufacturer/Supplier/Factory from China.
Sewage treatment 4A molecular sieve can remove NH3-N, Pb2+, Cu2+, Zn2+ and Cd2+ in wastewater. The wastewater discharged by industry, agriculture, civil use and aquaculture contains ammonia nitrogen, which not only endangers the survival of fish and other fish, pollutes the internal aquaculture environment, but also promotes the growth of algae and causes the blockage of rivers and lakes. Because of the high selectivity of 4A molecular sieve to NH4+, it has been successfully applied in this field. Sewage water from metal mines, smelters, metal surface treatment and chemical industries contains heavy metal ions which are extremely harmful to human beings. Using 4A molecular sieve to treat these sewage, not only can ensure that the water quality is qualified, but also can recover heavy metals. 4 a molecular sieves 4A molecular sieve is a sodium-exchange molecular sieve with a pore diameter of about 0.38nm. It can adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, and does not adsorb molecules with a diameter greater than 4A. Whoever chooses it, it performs better than any other molecule, and it is one of the most widely used molecular sieves in industry. Purpose: to remove moisture in the material. Type: Adsorbent Specification: Spherical or strip Material: molecular sieve Color: beige
