Effluent Treatment Plant Supplier in Chennai
Effluent Treatment Plant (ETP) — Design, Supply, Installation & Revamp
RRR ENVIRO SYSTEMS delivers robust ETP solutions for textile, dyeing, pharma, food, dairy, electroplating, chemical & general industry wastewater. We combine proven process design, chemical expertise and on-site services to meet TNPCB/CPCB standards.
Why ETP is essential
- Removes COD, BOD, TSS, oil & grease, colour and heavy metals
- Prevents legal penalties and plant shutdowns
- Enables safe discharge or reuse and reduces freshwater demand
Complete ETP Process Flow (Typical)
- Influent Screening & Oil & Grease Removal — Bar screens, oil separators
- Equalization & pH Conditioning — Mixing, flow smoothing
- Chemical Treatment — Coagulation & flocculation (jar test)
- Primary Clarifier — Solids settling
- Biological Treatment — ASP / MBBR / SBR based on feed characteristics
- Secondary Clarifier — Sludge recirculation & wasting
- Tertiary Treatment — PSF, ACF, UF/RO (if required)
- Disinfection & Disposal / Reuse
- Sludge Dewatering — Filter press / drying bed
Equipment & Parts We Supply
- Bar screens, oil & grease traps, equalization tanks
- Chemical dosing skids, mixing systems, dosing pumps
- Clarifiers, tube settlers, aeration blowers, diffusers
- MBBR media, ASP aeration systems, SBR control valves
- PSF, ACF, UF, RO modules and FRP/MS tanks
- Filter presses, sludge conveyors & dewatering units
Chemicals & Dosing — Typical Choices
| Chemical Type | Example Chemicals | Purpose / Typical Dosage |
|---|---|---|
| pH Correction | Caustic (NaOH), Lime, HCl | Adjust to 6.5–8.0 (site-specific) |
| Coagulant | Ferric Chloride, PAC, Alum | 50–500 ppm (jar test) |
| Flocculant | Cationic / Anionic Polyelectrolyte | 0.1–2.0 ppm (highly concentrated) |
| Oxidation | Hydrogen Peroxide, Fenton | For colour/COD reduction (site-specific) |
| Disinfection | Sodium Hypochlorite / Chlorine / UV | 1–5 ppm (as per target residual) |
| Sludge Conditioning | Polymer (Powder/Liquid) | 0.5–2% (dry cake improvement) |
| Defoamer | Silicone / Non-silicone | As required |
Dosing Calculation (Quick Example)
Formula: Dosage (ppm) × Flow (m3/hr) × 1000 = grams/hr
Example: Flow 20 m3/hr, coagulant 150 ppm → 150 × 20 × 1000 = 3,000,000 mg/hr = 3 kg/hr

FAQ — Quick Answers
Q1: How do you select chemicals for my ETP?
A: We perform site sampling and jar tests to select the most cost-effective coagulant/flocculant and recommend exact dosages.
Q2: Can you upgrade a running ETP without shutdown?
A: Yes; we plan phased upgrades and temporary bypass to avoid production loss in most cases.
Q3: Do you provide chemical supply on contract?
A: Yes — we supply chemicals on one-time, monthly or yearly contracts with doorstep delivery and dosing calibration.
