Ventilair Engineers Pvt. Ltd. (VEPL) offers specialized Effluent Treatment Plants (ETPs) designed for the plywood industry, where significant volumes of wastewater are generated during various stages of production, including veneer peeling, wood processing, adhesive application, and finishing. This wastewater often contains high levels of suspended solids, wood residues, chemicals, adhesives (such as formaldehyde-based resins), and oils, making it crucial to treat it effectively before discharge or reuse.

Our Plywood Industry ETPs are engineered to remove these pollutants, ensuring that the effluent meets environmental standards and supports sustainable water reuse practices within the facility.

Industry Insight by VEPL

The plywood manufacturing process involves a variety of chemical and physical treatments that result in highly polluted effluent streams. These effluents contain not only wood fibers and particles but also harmful chemicals, such as formaldehyde, phenol, and other adhesives, which need to be treated thoroughly before discharge.

At VEPL, we provide robust and efficient treatment solutions that help plywood manufacturers reduce their environmental impact, ensure compliance with discharge standards, and optimize water usage by recovering and recycling treated water.

Treatment Process Overview:

• Screening & Pre-treatment – Removes large wood particles and fibers from the effluent
• Equalization Tank – Balances variations in flow and pollutant concentration
• pH Correction & Chemical Dosing – Adjusts pH to neutral levels and prepares for coagulation
• Coagulation & Flocculation – Removes fine particles and adhesive residues
• Activated Carbon Filtration – Removes residual chemicals, oils, and odors
• Biological Treatment – Utilizes biological processes (aerobic or anaerobic) to treat organic waste and reduce COD/BOD
• Secondary Clarification – Settles out remaining sludge and provides final clarification of water
• Filtration & Polishing – Final treatment stages to ensure clean water for discharge or reuse
• Water Recycling System – Up to 85-90% water recovery for reuse in production processes or non-potable applications

Key Features:

• Designed for high solids content and chemical-laden effluents common in plywood production
• Effective removal of adhesives, phenols, and other harmful chemicals
• Compact & Modular Systems for easy installation in existing plants
• Up to 90% water recovery, reducing fresh water consumption
• Energy-efficient, low-maintenance, and cost-effective design
• Compliant with CPCB/SPCB regulations
