Pollachi is one of India's biggest coconut centres. Around it are coconut oil mills, desiccated coconut and coconut milk units, tender coconut processors, coir fibre and coir pith factories, dairies, jaggery units and food processors. Their wastewater is very different from the textile effluent of Tiruppur. Much of it is rich in fats, sugars and organic matter, and coir units add tannin-coloured water. It all flows into an area of canals and farmland that depends on the Aliyar and Parambikulam systems. Intellect Aqua designs effluent treatment plants (ETPs) for these industries from our nearby Coimbatore office.
Coconut Processing Effluent
Desiccated coconut, coconut milk and virgin coconut oil units wash large quantities of kernel and equipment. The wastewater carries oil, fine coconut particles, sugars and proteins, and turns sour quickly in the heat. A good treatment train is:
- Screening to catch kernel bits and fibre
- Oil and fat removal, by gravity separation or dissolved air flotation (DAF)
- Equalisation with mixing to stop souring and odour
- Anaerobic treatment for strong streams, which also produces biogas
- Aerobic polishing, clarification and filtration
The fats and solids recovered at the start can often be sold or used, which lowers the load on the rest of the plant.
Coir and Coir Pith Units
Coir fibre extraction and coir pith washing release brown, tannin-rich water with high suspended solids and, in some processes, salt. Coagulation and settling remove most solids. Further treatment then reduces colour and organic load. Where possible, the clarified water is reused for washing, which matters during dry months when borewells drop. See our coir industry solutions.
Dairy and Milk Chilling Centres
Dairies and milk chilling centres around Pollachi generate effluent from cleaning tankers, cans and equipment. It is biodegradable but strong. Fat traps, equalisation and biological treatment handle it well, and larger units can add a biogas plant to use the energy in the waste.
Jaggery, Food and Beverage Units
Jaggery units, snack makers and beverage bottlers produce sugary, high-BOD effluent. Biological treatment with good aeration and sludge control, sized for seasonal peaks, keeps these plants within limits.
How We Design Your ETP
- Visit your unit and trace every wastewater stream
- Measure flows across a full shift and through the season
- Test pH, BOD, COD, oil and grease, suspended solids and colour
- Check your TNPCB consent conditions
- Share a design, layout, capital cost and monthly running cost
Turning Waste Into Value
Coconut and dairy effluent contains energy and recoverable material. Anaerobic digestion yields biogas for boilers, dryers or canteens. Recovered fat and solids can be sold or composted. Treated water can irrigate farm land within your own premises, where permitted. These steps often cut running costs significantly.
Upgrading an Existing ETP
Many Pollachi units built a basic settling tank or lagoon years ago. Common problems now are smell, overflow during peak season and failed samples. We test the existing system and add what is missing, such as an oil removal stage, aeration or a clarifier, instead of starting from scratch.
Keep Sewage Separate
Workers' toilet and canteen sewage should go to a separate STP, so it does not disturb the process ETP.
Operation and Maintenance
We can provide operators, chemicals, spares, sludge handling and lab testing, plus the records you need for inspections. See our AMC plans.
Why Pollachi Industries Choose Us
- Experience with coconut, coir, dairy and food effluent
- ETP, biogas, STP and water treatment from one team
- Coimbatore base for quick visits and spares
- 700+ projects and 15+ years of industry experience
Intellect Aqua is a Coimbatore-based water and wastewater treatment company that builds and services plants across Tamil Nadu, including Pollachi.
Seasonal Peaks in Coconut Processing
Coconut arrivals rise and fall with the harvest, and many units run double shifts in peak months. An ETP sized only for the average day overflows when production jumps. We add equalisation capacity and modular aeration, so the plant copes with peak season and does not waste power in lean months. Sludge handling is sized for peak loads too, so solids do not build up and cause odour.
Tender Coconut and Coconut Water Units
Units that pack tender coconut water or process coconut water for vinegar and beverages produce sugary wash water that ferments quickly. Fast collection, equalisation and biological treatment keep it under control.
Areas We Serve
