Paints & coatings industry
This industry involves pigment mixing, resin blending, solvent addition, and packaging of paint and coating materials. Wastewater is created from equipment washing, floor cleaning, and rejected batches. Air pollution arises from solvent evaporation, VOC release, and pigment handling.
Wastewater can contain COD levels up to 25,000 mg/L, BOD around 8,000 mg/L, TSS over 3,000 mg/L, and hazardous solvents, pigments, phthalates, and heavy metals like lead, chromium, and zinc. Air emissions are dominated by Volatile Organic Compounds (VOCs), including xylene, toluene, formaldehyde, and odorous hydrocarbons.
A strong treatment line begins with Equalization, followed by Electrocoagulation for pigment and metal removal, then Advanced Oxidation Process (AOP) to break down complex organics. For final polishing, sand filtration and carbon filtration are applied. VOC-laden air is treated using Activated Carbon Filters, wet scrubbers, and explosion-proof ventilation systems.
Avlon specializes in handling solvent-rich wastewater and high-VOC air emissions with tailored chemical-resistant designs. With numerous installations in paint and coating plants, we ensure full environmental compliance and operational safety. Consult our team today to design your zero-failure pollution control system.
