Product Details

Non-toxic coagulant for heavy metal remove



Description:

It is a not-toxic and environmentally-friendly heavy metal catcher. This chemical could form a stable compound with most monovalent and divalent metal ions in waste water, such as: Fe2+,Ni2+,Pb2+,Cu2+,Ag+,Zn2+,Cd2+,Hg2+,Ti+and Cr3+, then reach the purpose of remove heavy mental from water. After treatment, the Precipitate cannot be dissolve by rain, There is no secondary pollution problem.

 

Application Field:

Remove heavy metal from waste water such as:

desulfurization wastewater from Coal-fired power plant  (wet desulfurization process) wastewater from Printed circuit board plating plant (Plated copper),Electroplating factory (Zinc),Photographic rinse,Petrochemical Plant, Automobile production plant and so on.

 

Advantage:

1/ High safety. Non- toxic, no bad smell, no toxic material produced after treatment.

2/ Good removal effect. It can be used in wide pH range, can be used in acid or alkaline wastewater. When metal ions coexist, they can be removed at the same time. When the heavy metal ions are in the form of  complex salt (EDTA, tetramine etc) which can not be removed completely by hydroxide precipitate method, this product can remove it as well. When it sediment the heavy metal, it will not be easily obstructed by coexisted salts in the waste water.

3/ Good flocculation effect. Solid-liquid separation easily.

4/ Heavy metal sediments is stable, even at 200-250℃ or dilute acid.

5/ Simple processing method, easy sludge dewatering.
