BIOFRESH – Natural Odour Control & Organic Sludge Breakdown Culture

Foul odours from STPs, ETPs, septic tanks, and drains are not only unpleasant but often signal deeper problems — like anaerobic zones, H₂S gas formation, and organic sludge accumulation. BIOFRESH is Venlar’s targeted microbial solution that tackles odour at the source by digesting volatile organics and restoring biological balance.

Free from masking agents or synthetic fragrances, BIOFRESH introduces non-pathogenic, fast-growing aerobic bacteria that degrade the organics responsible for odour. The result? A cleaner, safer, and smell-free environment — naturally and sustainably.
