Applications
Choose Water Treatment Chemicals by Application
Choose by the treatment objective and operating conditions. Verify grade suitability, dosage and local requirements before use.
Scale & Corrosion Control
HEDP and PBTC are phosphonate scale and corrosion inhibitors for industrial cooling water and boiler systems. Choose the grade by water hardness, pH and operating temperature, and set the dosage through trials.
Coagulants & Flocculants
Polyaluminium chloride (PAC), PolyDADMAC and polyamine are used for coagulation and flocculation in drinking water and wastewater clarification. Compare active content and basicity, then confirm performance by jar testing.
Industrial Process Water
For process water, match the product to the process stream, water quality and the other chemicals in your formulation. Each product page lists the CAS number and grade data so you can tell raw materials from ready-to-use formulations.
Pool Disinfection Chemicals
Calcium hypochlorite, sodium dichloroisocyanurate (SDIC) and trichloroisocyanuric acid (TCCA) are chlorine-based disinfectants for swimming pools and recreational water. Compare available chlorine and product form, store them away from incompatible chemicals and follow the product SDS.
The catalog also lists related materials; each product TDS gives its application and grade.
Source Water Treatment Chemicals from China
We ship water treatment chemicals from China in powder, granule, tablet and liquid forms, by FCL or LCL. Start with the CAS number, concentration and physical form you need. We can provide free samples so you can test them against your own water chemistry.
FAQ
Water Treatment Chemical Sourcing Questions
What to include when requesting specifications or samples.
Which water treatment chemicals can I source from China?
Our catalog covers PAC and cationic polymers for coagulation and clarification, HEDP and PBTC for scale and corrosion control, and chlorine-based disinfectants such as TCCA, SDIC and calcium hypochlorite. Each product page lists the CAS number, grades and technical documents.
What details should I send for a water treatment chemical quote?
Include the product name or CAS number, intended system, required grade, quantity, destination port and requested documents.
Can I request a TDS and SDS for a water treatment chemical?
Yes. Download the current TDS and SDS from the product cards above or from each product page. Batch test results are given on the COA that ships with every order.
