HECS ECO WASH – Car Wash Effluent Treatment Plant
Transform Your Car Wash with Effluent Treatment & Recycling
India’s booming automotive industry, with over 4 million vehicles sold every year, has fueled the rapid rise of car wash stations nationwide. While this growth drives convenience and profitability, it also creates a hidden challenge—excessive water consumption. On average, a single car wash uses 150–400 litres of fresh water, making traditional operations both costly and unsustainable.
HECS ECO WASH offers the solution. Our advanced Car Wash Effluent Treatment Plant (ETP) and wastewater recycling systems are engineered to recover up to 90% of used water, turning contaminated effluent into clean, reusable water. With ECO WASH, car wash businesses not only cut down water bills but also stay environmentally responsible while meeting pollution control board regulations.
Designed for car wash stations, automobile showrooms, and vehicle service centres, HECS ECO WASH- Car Wash ETP helps you run a profitable, eco-friendly, and future-ready operation—all while conserving one of our most precious resources: water.
Why Car Washes Need Effluent Treatment plant?
Car wash wastewater is more than just soap and water—it carries oil, grease, detergents, suspended solids, and even heavy metals. If left untreated, it can pollute soil, clog drains, and contaminate groundwater. This is why every automobile workshop and car wash station must install an Effluent Treatment Plant (ETP).
1. Water Scarcity
Freshwater is becoming increasingly scarce. With an ETP, car washes can reuse up to 90% of water, reducing dependency on freshwater sources and ensuring sustainable operations.
2. Cost Savings
Treating and reusing wastewater cuts down on high water bills and disposal costs, improving profitability while maintaining operations smoothly.
3. Brand Sustainability
Customers prefer eco-conscious businesses. An ETP helps position your workshop as a green, responsible automobile service centre, strengthening your reputation and attracting more clients

How HECS ECO WASH – Car Wash Effluent Treatment Plant Works?
HECS ECO LAUNDER Treatment Process
Our proven treatment technology ensures maximum pollutant removal and water quality for safe reuse
1
Inlet Screening
Car wash wastewater first passes through automated screening systems that remove plastics, stones, and large debris. This ensures only manageable wastewater enters the treatment line.
2
Oil Skimmer & Collection Tank
Floating oils and grease are removed using an efficient oil skimming unit. The collection tank then equalises flow variations, provides buffer storage, and ensures a stable and consistent treatment process.
3
Aerated Stirring & Coagulation
Aerated stirrers provide thorough mixing, while coagulants and flocculants destabilize oils, grease, and suspended solids, forming larger settleable flocs.
4
Clariflocculation Chamber
In this stage, colloidal particles, sludge, and emulsified oils aggregate into settleable flocs. The clariflocculator improves water clarity and prepares the effluent for biological treatment.
5
Aeration Chamber
The extended aeration process enables microbial digestion of organic pollutants. Continuous oxygen supply reduces BOD and COD levels through effective biological oxidation.
6
Settling Chamber
Gravity settling separates clarified water from biological sludge and flocculated particles. Concentrated sludge is diverted for safe handling.
7
Filter Feed Chamber
The clarified water is collected in a filter feed chamber before tertiary treatment. This step ensures stable flow and better performance of downstream filters.
8
Tertiary Treatment
Final polishing of water is achieved through multi-stage filtration:
- Pressure Sand Filter (PSF): Removes fine suspended solids
- Activated Carbon Filter (ACF): Eliminates odour, colour, and dissolved organics
Bag Filter: Provides polishing filtration (<5 mg/L TSS)
The treated water enters the UF feed tank for buffer storage and stable flow. It then passes through an Ultrafiltration (UF) membrane system, which removes colloids, bacteria, and fine impurities, ensuring reuse-quality standards.

Treated Water Outlet & Sludge Management
The final output is high-quality recycled water, safe for reuse in the washing system—reducing freshwater consumption by up to 90%. Meanwhile, sludge is dewatered using sludge bag units, reducing volume by 80–85% and producing dry sludge cake for safe disposal or reuse.
Water Reuse Applications
The treated water from the HECS ECO LAUNDER system is purified to a quality that enables safe, sustainable reuse in multiple areas of laundry operations and facility management, including:
- Laundry washing cycles – Reduce freshwater consumption by reusing treated water for non-critical wash and rinse processes.
- Toilet flushing – Supply restrooms with reclaimed water, lowering utility costs.
- Landscaping & gardening—Maintain lawns and green belts without drawing on potable water resources.
- Cooling tower makeup water – After additional polishing treatment, use recycled water for cooling systems to improve operational efficiency.
By integrating these reuse applications, commercial laundries not only cut water bills but also meet environmental compliance standards while supporting corporate sustainability goals.
