In the Sriperumbudur–Oragadam corridor, zero liquid discharge is driven as much by customers as by regulators. Plating and surface-finishing units often operate under ZLD consent conditions. Many automobile and electronics brands also ask suppliers to cut freshwater use and stop discharging effluent altogether. With borewells under stress and tanker water expensive, recovering water also saves money directly. Intellect Aqua designs ZLD and high-recovery systems for this belt, from segregated pre-treatment to evaporation.
Two Routes: High Recovery or Full ZLD
| Route | What it does | Suits |
|---|---|---|
| High recovery | ETP + UF + RO recover most of the water; reject handled by authorised means | Units without strict ZLD conditions that want to cut water use |
| Full ZLD | Adds an evaporator and dryer, so no liquid leaves the site | Plating, finishing and units with ZLD in their consent |
Many units start with high recovery and add evaporation later. We design the first phase so the second can be added without rework.
Inside a ZLD Plant for This Belt
- Segregation of plating, paint shop, oily and general streams
- Pre-treatment for each: chrome reduction, cyanide destruction, oil and paint sludge removal; see ETP for Sriperumbudur
- Combined treatment with equalisation, clarification and filtration
- Ultrafiltration to protect membranes
- Multi-stage RO for maximum recovery; see RO plants in Sriperumbudur
- Evaporation in an MVR or MEE unit
- Drying of the concentrate and authorised disposal of salts and sludge
MVR Is Often the Better Fit Here
Most units in this corridor do not have spare steam, but they do have reliable industrial power. Mechanical vapour recompression (MVR) evaporators run on electricity and often cost less to operate than steam-based MEE in this situation. We compare both on your actual energy prices before recommending one.
Reducing Load at the Source
Counter-current rinsing, drag-out recovery on plating lines, and better control of pre-treatment baths can cut effluent volume a lot. A smaller effluent stream means a smaller, cheaper ZLD plant and lower running costs. We include these options in every feasibility study.
Reusing Recovered Water
RO permeate and evaporator condensate are clean enough for rinsing, washing, cooling towers and, after polishing, boilers. We design storage and distribution so recovered water actually reaches these points. Water that goes unused is wasted money.
Reporting to Customers and Regulators
ZLD only counts if you can prove it. We install flow meters at inlet, recovery and reuse points, and set up simple daily and monthly reports. Your EHS team can then share water balance figures with TNPCB and with customer auditors.
Fixing an Existing Plant
If your recovery has dropped, membranes foul quickly or the evaporator keeps tripping, we sample every stage. We then prepare a fresh mass balance and fix the weak points first.
Operation and Maintenance
We offer full operation with our staff, or support visits for your team: membrane cleaning, evaporator checks, chemical management and reporting. See our Chennai AMC service.
Why Choose Intellect Aqua
- Experience with plating, automobile, rubber and engineering effluent
- Honest comparison of MVR and MEE for your site
- One team from segregation to evaporator
- 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 Sriperumbudur.
Typical Water Balance for a Component Supplier
For a mid-size auto component supplier, most effluent comes from washing and rinsing, a smaller share from paint shop pre-treatment, and a little from plating or special processes. Once the ETP and RO recover most of the water, only a small reject stream is left for the evaporator. Getting that first part right is what keeps ZLD affordable.
Space Planning in Crowded Plots
Factory plots in SIPCOT and private estates rarely have spare land. We use compact clarifiers, skid-mounted UF and RO, and vertical evaporators to fit ZLD into tight spaces. We also plan maintenance access so the plant can be serviced without stopping production.
Safety and Hazardous Waste
Plating sludge and evaporator salts are hazardous wastes. We plan covered storage, labelling and records that match your authorisation, so disposal is safe and inspections go smoothly.
Areas We Serve
Sriperumbudur, SIPCOT Sriperumbudur, Irungattukottai, Oragadam, Vallam Vadagal, Pillaipakkam, Mathur, Walajabad, Kanchipuram, Maraimalai Nagar and Mahindra World City.
We also build ZLD plants in Chennai, Hosur, Ranipet and Coimbatore. For recycling without full ZLD, see wastewater recycling.
