STP Chemicals — Coagulants, Flocculants & Polymers
Optimised chemical solutions for Sewage Treatment Plants — dosing SOPs, SDS, pilot support & quick supply
Reliable STP Chemicals — Reduce Sludge, Improve Clarification
RRR ENVIRO SYSTEMS supplies quality coagulants, flocculants, polymer aids, pH adjusters and sludge conditioners for municipal and industrial STPs (ASP / MBBR / SBR / MBR). Our chemistries are lab-tested, membrane-friendly and come with dosing SOPs and SDS.
Product Range
- Inorganic Coagulants: Ferric Chloride, Aluminium Sulphate (Alum), Ferrous Sulphate — turbidity & colour removal
- Organic Coagulants (PAC): Poly Aluminium Chloride — rapid floc formation & improved settling
- Flocculants / Polymers: Cationic, Anionic & Non-ionic Polymers — sludge dewatering & DAF performance
- pH Adjusters: Lime, Caustic Soda, Sulfuric Acid — neutralization & precipitation
- Defoamers / Antifoam: Silicone & non-silicone types — control excessive foaming in biological tanks
- Sludge Conditioners: Polymers for filter press & sludge cake improvement
- Dechlorinators: Sodium Bisulfite (SMBS) — neutralize residual chlorine before biological stage
- Biological Nutrients & Enzymes: For low-strength sewage to boost biological activity
- Odour Control Chemicals: Masking & oxidizing agents for foul odours
Indicative Dosing Guide (Typical)
| Chemical | Purpose | Indicative Dose |
|---|---|---|
| Ferric Chloride | Coagulation for TSS & color | 10–100 mg/L (site-specific jar test) |
| Alum (Aluminium Sulphate) | Coagulation & pH correction | 20–120 mg/L |
| PAC | Rapid flocculation (low turbidity) | 5–50 mg/L |
| Cationic Polymer | DAF & sludge dewatering | 0.1–5 mg/L (ppm) or mg/L as per polymer |
| SMBS | Dechlorination | 2–5 mg/L |
| Defoamer | Foam control | 0.5–5 mg/L (spot dosing) |
*Doses are indicative. Final dosing requires jar test / pilot trial. We provide SOPs for each plant after sample analysis.
Where chemicals are used in STP
- Equalization Tank — pH correction & initial conditioning
- DAF / Coagulation Unit — PAC / Ferric dosing for solids removal
- Primary Clarifier — coagulants & flocculants to improve settling
- Biological Reactor — nutrients & enzyme dosing (if needed)
- Secondary Clarifier & Polishing — polymer dosing for sludge dewatering
- Sludge Dewatering — polymer conditioning for filter press / belt press
Handling, Storage & Safety
- Store chemicals in a cool, dry, ventilated area away from direct sunlight
- Keep incompatible chemicals separated (acidic vs alkaline storage)
- Use PPE — gloves, goggles, apron and mask when handling concentrated products
- Provide SDS (Safety Data Sheets) with every shipment — follow local regulations for disposal
- Training: We provide simple SOP & safety checklist for your operators
Packaging & Supply

FAQ
- Q: How do you choose the right coagulant?
- A: We perform jar tests on your samples to identify the best chemical and dose for maximum solids removal and lowest sludge volume.
- Q: Do you provide polymer for filter press?
- A: Yes — we supply polymer grades optimized for dewatering and cake formation, with recommended feed systems and dosing rates.
- Q: Can you supply monthly consumables on contract?
- A: Yes — we offer supply contracts and scheduled deliveries to ensure uninterrupted plant operations.
- Q: What is the lead time for bulk supply?
- A: Chennai metro: 24–48 hours typical; Pan-India: 3–7 business days depending on stock and location.
