We are judged by your outlet,
not by our catalogue
Henan Zhengjia Environmental Technology Co., Ltd. is a water treatment chemical manufacturer and technical service provider based in Zhengzhou, Henan, China.
Water treatment cost should not be paid for in trial and error. Look at the water first, choose the chemistry second, talk about price last.
Working across coagulation, flocculation, decolourisation, defluoridation and ecological restoration, we have built a product system that covers municipal wastewater, industrial effluent and river-lake projects. The line includes polyacrylamide (PAM and CPAM), polyaluminium chloride (PAC), decolorizing flocculant, hydroxyl co-coagulant, fluoride removal agent and river-lake remediation agent.
Our customers operate municipal treatment plants, textile and dyeing mills, coal chemical complexes, photovoltaic and semiconductor fabs, plating shops, pulp and paper mills, and river restoration projects. Because pollutant profiles differ so widely, we do not sell one chemical for every problem — we configure a combination for the water in front of us and hold the cost per cubic metre inside a sensible range.
The company runs a formulation laboratory and a jar test bench, with in-house testing for solid content, molecular weight, basicity and charge density. A retention sample is kept for every production batch, and every proposal we issue is backed by bench data rather than by a specification sheet alone.
From trading chemicals
to owning the outcome
It took more than a decade to move from reselling drums to taking responsibility for what comes out of the outlet.
Company founded
Started as a flocculant supplier and formulation service for textile and paper mills in Henan.
First compounding line
Commissioned the first polyacrylamide compounding line, moving from trading to in-house production.
Water treatment laboratory
Introduced the test-first, quote-second workflow and began building the sector water and formula database.
Defluoridation and decolourisation lines
Added deep fluoride removal agents and decolorizing flocculants for PV, semiconductor and dyeing customers.
Ecological restoration
Launched the river and lake remediation agent and joined several black-odour and sediment projects.
A closed loop from raw material to outlet
A chemical performs only as well as the testing, blending and site operation around it. We keep all four stages in-house.
Standardised production
Manufactured to national and industry standards, with retention samples and full batch traceability.
Formulation development
In-house lab and jar test bench adjust formula and dosing point for each water source.
Batch quality control
Solid content, molecular weight, basicity and charge density tested per lot; data ships with the goods.
Field technical service
Engineers commission the dosing system on site or remotely until the plant runs stable.
