Key Engineering Highlights
- ETP tanks must resist aggressive chemical effluents, pH swings (pH 1 to 14), and biological sludge degradation.
- Robust construction using SS 316L, MS with FRP/Epoxy lining, or HDPE liners ensures decade-long zero-leak operation.
- Custom clarifier tanks with torque-protected rake mechanisms and bridge walkways optimize sludge sedimentation.
- Helps industrial plants in Vatva, Naroda, Ankleshwar, and Dahej meet strict GPCB & CPCB pollution norms.
The Critical Need for Reliable ETP Tanks in Industrial Estates
With stringent environmental guidelines enforced by the Gujarat Pollution Control Board (GPCB) and Central Pollution Control Board (CPCB), industrial units operating in chemical clusters like Vatva GIDC, Naroda, Ankleshwar, Dahej, and Vapi must implement robust Effluent Treatment Plants (ETP) and Zero Liquid Discharge (ZLD) facilities.
Vishwakarma Engineering designs and fabricates heavy-duty industrial ETP tanks, clarifiers, neutralization vessels, and sludge holding tanks that withstand harsh chemical mixtures, high salinity, and heavy biological loads.
Core Equipment in an Industrial ETP System
We manufacture custom-engineered equipment for each phase of effluent treatment:
- Equalization & Neutralization Tanks: Equipped with heavy-duty chemical-resistant agitators to balance fluctuating pH levels from upstream processes.
- Flash Mixers & Flocculators: High-efficiency mixing units for rapid dosing of coagulants (alum, poly-electrolytes) and gentle floc formation.
- Primary & Secondary Clarifiers: Cylindrical tanks with conical hoppers, central inlet feedwells, peripheral V-notch weirs, and motorized center-driven sludge scraper rakes.
- Aeration Tanks & Bioreactors: Large-capacity vessels engineered for fine-bubble diffused aeration and biological COD/BOD reduction.
- Filter Press Sludge Holding Tanks: Heavy-gauge slurry tanks designed for feed slurry staging before mechanical dewatering.
Corrosion Protection & Liner Technologies
Because industrial wastewater can be highly unpredictable, we offer tailored protective barrier systems:
- FRP (Fiber Reinforced Plastic) Lining: Multi-layer isophthalic or vinyl ester resin matrix applied over blast-cleaned steel.
- High-Build Glass Flake Epoxy Coating: 1,000+ micron protective layer providing impermeable barrier against moisture and chemical ions.
- Full Stainless Steel 316L Construction: Complete stainless steel vessels for high-salinity and pharmaceutical effluent streams.
