Excessive and stubborn foam is a common problem in industrial wastewater treatment, biochemical systems, and chemical production processes. Most foam is produced by residual surfactants and active organic substances in the water. Conventional silicone defoamers can eliminate foam quickly but easily cause membrane blockage, silicon residue and secondary water pollution, which seriously affects reverse osmosis pretreatment and advanced water treatment systems. For factories that require clean, residue-free foam suppression under harsh working conditions, a professional non-silicon polyether alcohol defoamer has become the safest and most effective solution for stable industrial foam management.
Stubborn foam in wastewater systems is difficult to eliminate naturally because surfactant molecules form stable elastic foam films on the water surface. In high-temperature and strong alkali working environments, ordinary defoamers often fail, lose activity, or produce floating flocs that affect water quality. Many traditional defoaming products have poor water dispersion and cannot penetrate dense foam layers, resulting in repeated foaming and unstable system operation. These persistent problems greatly reduce the efficiency of wastewater foam control agent and increase daily maintenance pressure for environmental protection workshops.
Factory operators usually adopt several conventional defoaming methods, all of which have obvious drawbacks. Physical defoaming by water spraying can only remove surface foam temporarily and cannot inhibit continuous foam generation. Traditional silicone defoamers have fast defoaming speed but are incompatible with membrane systems, easily blocking membrane pores and affecting water reuse. Mineral oil-based defoamers have poor water solubility and are prone to oil floating and COD rising. Most common products cannot adapt to high temperature and strong alkali environments, making long-term stable foam control difficult in complex industrial water systems.
Shanmei Environment’s non-silicon polyether alcohol defoamer is a specially developed membrane compatible defoamer for professional water treatment scenarios. Made of pure polyether alcohol formula without silicon components, the product features excellent penetration and diffusion performance in liquid. It can quickly penetrate into dense foam layers, break foam films in a short time, and effectively suppress new foam regeneration. Different from ordinary defoamers, this high temperature alkali resistant defoamer maintains stable defoaming performance under strong alkali and high-temperature working conditions, ensuring continuous and reliable foam elimination throughout the operation cycle.
This non-silicon polyether alcohol defoamer shows outstanding application advantages in actual industrial operation. The product is a milky white or light yellow uniform fluid with 20% solid content and moderate viscosity ranging from 500 to 1000 CS. Adopting non-ionic formula, it has excellent water dispersibility and can be completely and evenly dissolved in various water systems without floating oil or precipitation. The product is non-flammable and safe for factory storage and on-site dosing. It features ultra-high compatibility with liquid water treatment systems, does not damage microbial activity in biochemical tanks, and never blocks membrane apertures in reverse osmosis pretreatment systems.
The non-silicon polyether alcohol defoamer is widely applicable for multiple industrial scenarios. It perfectly suits various domestic and industrial sewage treatment, biochemical pool water treatment, biological water treatment, and reverse osmosis pretreatment systems. It also works stably in daily chemical production, power plant desulfurization and decarbonization systems, and chemical fertilizer anti-caking agent systems. It is especially suitable for high-standard water treatment projects that strictly prohibit silicon residue and membrane contamination.
In actual on-site use, the defoamer can be directly added by dripping or spraying. It can also be diluted with clean water before application according to construction needs. The conventional recommended dosage is 0.1% to 0.3% of the total liquid volume of the system. To guarantee stable performance, diluted solutions should be used immediately. If long-term storage of diluted liquid is required, appropriate stabilizers must be added.
A wastewater treatment plant faced heavy foam buildup in its biochemical tank, and the subsequent reverse osmosis unit could not tolerate silicone contamination. After testing Shanmei’s non-silicon polyether alcohol defoamer, the stubborn foam generated by surfactants rapidly disappeared. The product did not clog membrane pores, and the whole water treatment system ran steadily under high temperature and alkaline operating conditions.
Can this defoamer be used for reverse osmosis pretreatment? Yes, this membrane friendly formula contains no silicone and will not block membrane apertures. Is it suitable for strong alkali and high temperature working conditions? This non-silicon polyether alcohol defoamer keeps stable defoaming capacity under high temperature and strong alkali environments.
Packaging options include 25kg and 50kg plastic drums. Proper sealed storage away from direct sunlight and high temperature is required to retain product performance.
