Import Defoamer For Water Treatment — Buy in wholesale FOB from Supplier in China

Hangzhou Seraph Chem Corp. supplies defoamers formulated for industrial water treatment systems, including silicone-based and polyether-based variants. The silicone defoamers contain polydimethylsiloxane as the active component, typically at concentrations between 10% and 40%, while the polyether types are non-silicone and suited for low-temperature applications. These products are designed to act rapidly in high-shear environments such as aeration tanks and MVR evaporators, where foam stability is a persistent operational issue.

The formulations are engineered to be compatible with municipal and industrial wastewater streams, landfill leachate, and seawater desalination units. Silicone defoamers offer high thermal stability up to 150°C and are resistant to hydrolysis, while polyether variants provide better dispersibility in alkaline conditions and lower surface tension. Both types are free from volatile organic compounds and meet standard industrial safety guidelines for aquatic environments. The supplier does not specify exact viscosity or density values but confirms availability in liquid form for direct dosing.

Buyers in wastewater treatment plants, food processing facilities, and desalination contractors use these defoamers to maintain pump efficiency and reduce maintenance downtime. The supplier offers free samples upon request and supports custom formulation adjustments based on pH, temperature, and foam composition. Packaging is typically in 25kg drums or 200kg IBC totes, with bulk orders available. Lead time and incoterms must be confirmed directly with the supplier, as they are not listed.
