Industrial Defoamers — Silicone and Non-Silicone
We don't just sell chemicals. We help customers achieve their objectives.
A defoamer breaks foam that has already formed. An antifoam stops new foam forming. Venlar makes both, in silicone and non-silicone chemistries, and matches the grade to your foam in a lab test before you order.
Start with the problem. We'll help you find the right solution.
Silicone Defoamers (VenFoam 10 series)
- Many strengths: VenFoam 10, 20, 30, 40, 50 and 100 (% active silicone)
- Typical dose 10–50 ppm, confirmed by lab and site trial
- Fast knockdown and long persistence across a wide pH and temperature range
- For ETP and STP aeration tanks, MBR/SBR, equalisation tanks, MEE feed, pulp, detergent, ethanol production, paper and textile processing
Non-Silicone Defoamers (VenFoam 20 / 30 series)
- Non Silicone - based [Glycol / mineral-oil]
- For processes where silicone causes problems: paints and coatings (craters, fisheyes), construction chemicals and some paper grades
- Industries: ETP & STP · Paper & pulp · Textile processing · Paints & coatings · Construction chemicals
- Packing: 50 kg carboys, 200 kg drums
Coagulants for Wastewater, Mineral Processing and Battery Recycling
A coagulant neutralises the charge on fine suspended particles so they clump together. A polyelectrolyte then binds them into large flocs that settle or dewater. Venlar supplies both and sets the dose order with a jar test on your water.
Start with the problem. We'll help you find the right solution.
- Industrial ETP: textile, dye, pharma, paper, food
- Mineral ore processing: process water and tailings clarification
- Battery recycling: process water and leach-liquor clarification
- RO and MEE feed pre-treatment
What are you trying to achieve?
We help identify why biological growth is not developing and recommend the right combination of process improvements and biological support.
From primary treatment improvements to biological support and nutrient management, we work across the process rather than treating ammonia as a one-product problem.
We look beyond a single product to understand where the COD problem is coming from and how the treatment process can be improved.
Microbial solutions control odour at the source — no masking agents, no chemical cover-ups. Works in aeration tanks, clarifiers, and sludge handling areas.
We provide practical operating guidance and technical support to help your team get the process under control.
We help identify the appropriate polymer and application approach to improve dewatering performance and manage chemical consumption.
Three things we believe
We keep working the problem—one parameter, one change and one objective at a time.
Our Products
Inorganic and organic coagulants & decolourizer for pre-treatment and primary clarification. Removes colour, TSS, and suspended solids in pharma, chemical, food, and textile effluent. 10+ grades manufactured. Very low dosing optimised for your plant load.
Silicone & Glycol based defoamers control foam in aeration tanks, equalisation, and clarifiers without affecting biomass. Safe for primary and secondary treatment. Available in 50 L & 200 L packs.
VenOne bio products range rebuild MLSS, reduce COD/BOD, and stabilize biological processes in industrial aerobic tanks. Fast recovery from shock loads, downtime, or monsoon dilution. 10–14 day rebuild from below 1500 to 3000+ mg/L.
Anionic and cationic polymers (45+ grades imported) for flocculation, sludge dewatering, and clarification. Reduces moisture content in dewatered cake, improves belt press throughput, cuts disposal volume.
More than chemicals. Technical ownership.
When you work with Venlar, you don't simply receive a drum, bag or container and a dosage recommendation. You get support around the solution.
