Ventilair Engineers Pvt. Ltd. (VEPL)
Ventilair Engineers Pvt. Ltd. (VEPL) is a leading Industrial Water Recycling ETP Manufacturer in India, delivering advanced, energy-efficient, and CPCB-compliant solutions for wastewater treatment, reuse & zero liquid discharge (ZLD).
Our Water Recycling Effluent Treatment Plants (ETP) are specially designed to treat complex industrial effluents from pharma, chemical, textile, food, plating, automobile & engineering industries, ensuring maximum water recovery and minimum environmental impact.
🔬 Why Water Recycling ETP is Important?
Industrial wastewater contains high levels of BOD, COD, TSS, oil & grease, and toxic chemicals, which must be treated before discharge or reuse.
BOD (Biological Oxygen Demand) → biodegradable pollution load
COD (Chemical Oxygen Demand) → total organic load
TSS (Total Suspended Solids) → suspended particles
👉 These parameters define wastewater strength and treatment efficiency
✔ Proper treatment reduces pollution and enables reuse
✔ Mandatory as per CPCB / SPCB norms
✔ Supports water conservation & sustainability
