Intellect Aqua designs and builds effluent treatment plants (ETPs) for dyeing, bleaching, printing and washing units in Tiruppur. Textile effluent is one of the hardest wastewaters to treat — deep colour, high COD, fluctuating pH and heavy dissolved salts — and Tiruppur units must meet zero liquid discharge (ZLD) conditions. We design plants that remove colour and organics, recover water for reuse and handle the reject stream, so your unit stays compliant and keeps running.
The Challenge of Treating Textile Effluent in Tiruppur
Tiruppur's knitwear industry depends on hundreds of dyeing and processing units, and their wastewater has directly affected the Noyyal river and groundwater in the region. As a result, dyeing and bleaching units here operate under strict ZLD conditions — treated water has to be recovered and reused, not discharged.
Textile effluent changes batch by batch. Reactive dyeing adds large quantities of salt, which pushes up total dissolved solids (TDS). Bleaching brings high pH and peroxide. Printing and washing add gums, chemicals and colour. A plant designed for "average" effluent struggles on the day the dye house runs dark shades at full load. That is why we design every textile ETP from a study of your actual process, shades and daily water use. We collect samples across different batches, check pH, COD, colour and TDS, and size each stage for your worst day, not your best.
Our Textile ETP Process
Collection, Screening and Equalisation
Effluent from all machines is collected, screened and held in an equalisation tank with mixing, so the plant receives a steady flow and composition instead of sudden shocks.
Neutralisation and Physico-Chemical Treatment
pH is corrected and coagulants and flocculants are dosed to remove colour, suspended solids and part of the COD. Sludge is separated in a clarifier and dewatered in a filter press.
Biological Treatment
An aerobic biological stage, such as MBBR or extended aeration, breaks down the remaining organic load. This step reduces chemical consumption and protects the membranes downstream.
Tertiary Treatment and Water Recovery
Pressure sand and activated carbon filters, followed by ultrafiltration and RO, recover clean permeate that goes back to the dye house for reuse.
Reject Management for ZLD
The concentrated RO reject is further treated using multi-stage RO and evaporators, so no liquid leaves the unit. Recovered salt can be reused in reactive dyeing where the process allows. Learn more about our ZLD plants in Tiruppur.
Who We Build Textile ETPs For
- Dyeing units for cotton, hosiery and knitted fabric
- Bleaching and mercerising units
- Fabric and garment printing units
- Garment washing and finishing units
- Processing units that want to upgrade an old ETP to full ZLD
If your unit discharges only domestic sewage from staff and hostels, a separate STP may be enough — see our effluent treatment plants in Tiruppur for other industries.
Upgrading an Existing ETP
Many Tiruppur units run plants built years ago that can no longer handle today's production or compliance requirements. We audit existing ETPs, find the bottleneck — usually equalisation, biological capacity or RO fouling — and upgrade only what is needed, instead of rebuilding the whole plant.
Sludge Handling and Running Cost
Chemical sludge is one of the biggest hidden costs in a textile ETP. We size the clarifier and filter press so sludge is removed and dewatered properly, which reduces the volume you store and send for disposal.
Running cost in a textile ETP comes mainly from chemicals, power for aeration and RO, membrane cleaning and evaporation. We design to keep each of these under control: equalisation and biological treatment cut chemical use, correctly sized blowers save power, and good pre-treatment keeps RO membranes clean for longer. Before you approve the project, we share an estimate of daily operating cost so there are no surprises after commissioning.
