Effluent Treatment Plants (ETP)Leave the factory clean.

Every industry makes a different effluent. We study yours, then design, build and run an ETP that treats it to your consent conditions or prepares it for reuse.

What it is

In plain words.

Industrial effluent carries whatever the process leaves behind: oil and grease from food units, dyes from textile houses, solvents and salts from chemical plants, and high organic loads from dairies and pharma. It cannot go straight to a drain or river. An effluent treatment plant removes these pollutants step by step, using physical, chemical, biological and, where needed, membrane processes.

No two ETPs are the same. We start with an analysis of your effluent and its flow pattern, then size each stage to suit. The plant can be built to meet your discharge consent, or taken further so treated water returns to your process. Zeal covers design, supply, installation, commissioning, automation and operation and maintenance under one contract.

How it works

Stage by stage.

  1. Collection & storage

    Effluent from different sections is collected and held so flow and strength stay steady.

  2. Mixing & cooling

    Streams are blended and hot effluent is cooled so later stages work as designed.

  3. Neutralisation

    Acid or alkali is dosed to bring pH into the range the treatment needs.

  4. Chemical coagulation

    Coagulants and flocculants gather fine particles and some dissolved pollutants into settleable flocs.

  5. Biological oxidation

    Aerated tanks let bacteria break down the organic load that raises BOD and COD.

  6. Sedimentation

    Solids settle and are separated as sludge, which goes to a thickener for dewatering.

  7. Filtration

    Filters polish the clear water before discharge, reuse or further treatment.

Options

Built to suit the site.

  • Physico-chemical ETP

    Neutralisation, coagulation and settling for effluents with metals, colour or suspended solids but little organic load.

  • Biological ETP

    Physico-chemical stages followed by aeration, for effluents high in BOD and COD such as food, dairy and pharma.

  • Compact ETP

    A packaged plant for smaller flows or tight sites, with stages combined into a smaller footprint.

  • ETP with recycling

    Adds ultrafiltration and RO after treatment so a large share of the water returns to your process.

    Maintain

    Operation, preventive maintenance and AMC under Zeal-Care, with written reports.

Questions

Asked before every project.

What do you need from us to design an ETP?

Your daily effluent volume, a sample or recent lab report, details of the processes that produce it, and the discharge or reuse standard in your consent. We visit the site to check space and levels.

Can our existing ETP be upgraded?

Often, yes. We audit the plant, find the stages that are overloaded or not working, and propose changes before adding new equipment.

Do you run the plant after commissioning?

Yes. We offer operation and maintenance and AMC contracts that cover operators, preventive maintenance, chemicals and compliance records.
