What Is an Effluent Treatment Plant (ETP)?
An Effluent Treatment Plant is a wastewater treatment system that processes industrial effluent — wastewater generated by manufacturing and production operations — before it is discharged into the environment or reused within the facility. Industrial effluent contains harmful contaminants that domestic sewage does not: heavy metals like lead, chromium, and mercury; synthetic dyes and colorants; chemical oxygen demand (COD) loads; oil and grease; acids and alkalis; and toxic organic compounds.
Untreated industrial discharge into drains, rivers, or groundwater is a criminal offence under the Environment Protection Act 1986 and the Water (Prevention and Control of Pollution) Act 1974. CPCB and State PCBs conduct regular inspections of industrial units in Faridabad, Gurugram, Noida, and other Delhi NCR industrial zones. Non-compliant units face heavy fines, forced closure, and legal proceedings.
A well-designed ETP removes 90–99% of BOD, COD, suspended solids, heavy metals, and colour from your effluent, producing water safe for discharge or reuse in cooling towers, gardening, and process applications.

Paper & Pulp | High BOD/COD, chlorine compounds, lignin | Biological ETP + clarification |
Our ETP Treatment Process — Stage by Stage
Every Meridian ETP is engineered around a multi-stage treatment process tailored to your specific effluent characteristics. A raw water analysis is conducted before design to confirm the correct process sequence.
Stage 1 — Preliminary Treatment
Bar screens and grit chambers remove large solids, rags, plastics, and coarse debris from the incoming effluent stream. This protects downstream pumps and equipment from damage and clogging. For oily effluents, an oil and grease trap is added at this stage
Stage 2 — Primary Treatment (Physico-Chemical)
The effluent enters an equalisation tank, which buffers flow variations and averages out pollutant concentrations — critical for industries with batch discharge. pH correction is then applied using acid/alkali dosing. In a flash mixer and flocculation tank, coagulants (alum, FeSO4, or polyelectrolyte) are added to aggregate fine suspended particles into larger flocs. These flocs settle out as sludge in the primary clarifier, removing 40–70% of suspended solids and 25–40% of BOD at this stage alone.
Stage 3 — Secondary Treatment (Biological)
Biological treatment degrades dissolved organic matter using aerobic or anaerobic microorganisms. We deploy the most appropriate technology based on your COD load and space:
-
MBBR (Moving Bed Biofilm Reactor) — compact, high efficiency, ideal for retrofitting existing tanks
-
Activated Sludge Process (ASP) — proven, reliable for moderate-to-high BOD loads
-
SBR (Sequential Batch Reactor) — best for variable flow or batch discharge patterns
-
MBR (Membrane Bioreactor) — highest output quality; treated water suitable for direct reuse
Biological treatment achieves 85–95% BOD and COD reduction when combined with primary treatment.
Stage 4 — Tertiary Treatment & Polishing
For industries requiring very high-quality treated water or those targeting ZLD (Zero Liquid Discharge), tertiary treatment stages are added: sand filters and activated carbon filters remove residual suspended solids and trace organics; UV or chlorine disinfection eliminates pathogens; and a final polishing RO stage can produce water of near-potable quality suitable for process reuse.
Sludge Management
Sludge generated at primary and secondary stages is thickened in a sludge thickener, then dewatered using a filter press to produce dry sludge cakes. Dry sludge is disposed of as per CPCB hazardous waste norms (for industries generating hazardous sludge) or used as compost/landfill (for non-hazardous sludge). Meridian provides complete sludge handling systems as part of the ETP package.

Types of ETP Systems We Manufacture
Civil-Based ETP (RCC Construction)
All treatment tanks (equalisation, flash mixer, flocculation, clarifier, aeration, sludge) are constructed as permanent RCC (Reinforced Concrete Cement) structures at your site. Designed for 20–25 years of operational life. Best for large-capacity plants (200 KLD+) where permanence and long-term cost are the priority.
Packaged / Prefabricated ETP
A compact, factory-built ETP system installed in FRP, MS, or SS tanks. Delivered to site as a ready-to-connect package. Requires minimal civil work and can be installed in 7–15 days. Ideal for small and mid-size industries (up to 200 KLD), industries in rented premises, or companies that need a fast compliance solution ahead of a PCB inspection.
Zero Liquid Discharge (ZLD) System
A ZLD system treats 100% of your effluent so that no liquid waste is discharged outside the plant boundary. The process combines biological treatment + RO + Multiple Effect Evaporator (MEE) + Agitated Thin Film Dryer (ATFD) to recover all water and convert residual salts into dry solid powder. ZLD is now mandatory for textile, tannery, sugar, distillery, and pulp and paper industries under CPCB norms. It is also increasingly preferred by industries in water-stressed zones across Haryana

Frequently Asked Questions — ETP Plants
Q1. Is an ETP mandatory for my industry in Faridabad?
Yes. Under the Water (Prevention and Control of Pollution) Act 1974 and the Environment Protection Act 1986, all industrial units generating liquid effluent are required to treat wastewater before discharge. In Haryana, HSPCB issues Consent to Establish (CTE) and Consent to Operate (CTO) only to units that have approved ETPs in place. Industries without functioning ETPs face fines, forced closure, and in repeat cases, criminal liability under the National Green Tribunal (NGT) orders.
Q2. What is the difference between an ETP and an STP?
An ETP (Effluent Treatment Plant) treats industrial wastewater — from factories, manufacturing units, and industrial processes — which contains chemicals, heavy metals, dyes, solvents, and other industrial pollutants. An STP (Sewage Treatment Plant) treats domestic sewage from toilets, bathrooms, and kitchens, which mainly contains organic matter and pathogens. The two have fundamentally different treatment processes and cannot be interchanged. If your facility generates both types of wastewater, you need both systems.
Q3. What is the difference between a physico-chemical ETP and a biological ETP?
A physico-chemical ETP uses physical processes (screening, sedimentation, filtration) and chemical reactions (coagulation, flocculation, pH adjustment, chemical precipitation) to remove contaminants — especially heavy metals, suspended solids, colour, and inorganic pollutants. It does not rely on microorganisms. A biological ETP uses aerobic or anaerobic bacteria to break down dissolved organic matter (BOD/COD). Most industrial ETPs use both in sequence: physico-chemical treatment in primary stages, biological treatment in secondary stages.
Q4. What is ZLD and is it mandatory for my industry?
Zero Liquid Discharge (ZLD) is a treatment philosophy where 100% of the effluent generated is treated and recovered — no liquid waste leaves the plant boundary. The CPCB has made ZLD mandatory for textile (dyeing and printing), sugar, distillery, tannery, and pulp and paper industries. The National Green Tribunal has also directed several industrial clusters in Delhi NCR to adopt ZLD systems. Even where not mandatory, ZLD is increasingly adopted by industries to achieve water self-sufficiency and avoid water purchase costs.
Q5. How long does it take to install an ETP?
Installation time depends on the type and capacity: Packaged ETPs (up to 100 KLD) take 7–15 days from delivery to commissioning. Civil-based ETPs (100–500 KLD) take 30–60 days for construction and commissioning. Large civil ETPs with ZLD (500 KLD+) take 60–120 days. The timeline begins after site readiness — civil area cleared, electrical supply available, and effluent inlet line in place
Q6. Can ETP-treated water be reused?
Yes, in most cases. With secondary biological treatment, treated water meets norms for irrigation and gardening reuse. With tertiary treatment (sand filter + activated carbon + UV), it meets norms for cooling tower makeup and toilet flushing. With a polishing RO stage, the treated water quality approaches potable standards and can be reused in most process applications. Reusing ETP-treated water significantly reduces your freshwater purchase costs.
Q7. What happens to the sludge generated by an ETP?
ETP sludge is separated, thickened, and dewatered using a filter press into dry sludge cakes. For non-hazardous industries (food, dairy), dewatered sludge can be used as compost or sent to authorised landfills. For hazardous industries (electroplating, chemicals, pharma), sludge must be classified per CPCB Hazardous Waste Management Rules and disposed of through a CPCB-authorised Treatment, Storage, and Disposal Facility (TSDF). Meridian provides sludge disposal guidance and documentation as part of our compliance support service.
Q8. What does an ETP AMC include?
Our Annual Maintenance Contract (AMC) covers: 12 scheduled maintenance visits per year; emergency breakdown response within 24 hours; replacement of consumables (filter media, chemical dosing, UV lamps); quarterly treated water quality testing with PCB-format lab reports; assistance with PCB consent renewal documentation; and operator refresher training.
