“Faster Settling. Drier Cake. Clearer Water.”

Innovacorp manufactures polyelectrolytes in Hyderabad for industries that need reliable solid-liquid separation. The city's ETPs, CETPs and process industries handle very different suspensions — pharma sludge from Genome Valley, textile dye effluent from the surrounding belt, metal hydroxide sludge from electroplating units, and paper mill white water from Patancheru. Each suspension responds to a different polymer chemistry. Picking the wrong one wastes chemical, produces wet cake and leaves turbidity in the treated water.

Why Polyelectrolyte Selection Matters in Hyderabad

Polyelectrolytes work through two mechanisms — charge neutralisation and inter-particle bridging. The right polymer for a given suspension depends on the particle charge, the suspended solids concentration and the shearing conditions in the system.

In practice, most plants get this wrong in one of three ways. They use a polymer with the wrong charge, they use a molecular weight that is too low or too high for the application, or they prepare and dose the polymer incorrectly. Any of these leads to poor settling, high turbidity and wet sludge. Getting the chemistry right is usually cheaper than increasing the dose.

Where It Is Used — Hyderabad Applications

• Pharma & Bulk Drug ETPs: Genome Valley, Shamirpet, Bollaram — sludge dewatering on filter presses and centrifuges.
• Textile & Dye Effluent: Surrounding industrial clusters — colour removal and floc settling after coagulation.
• Metal Finishing Units: Electroplating and surface treatment units — metal hydroxide sludge settling.
• Paper & Pulp Mills: Patancheru–Medak belt — white water clarification and fibre recovery.
• Food Processing ETPs: Dairy, beverage and packaged food units — organic sludge dewatering.
• Municipal STPs: Residential and commercial sewage treatment plants — sludge thickening and dewatering.

Types We Manufacture

• Anionic Polyacrylamide (APAM): For inorganic sludge, mineral processing and paper mill white water.
• Cationic Polyacrylamide (CPAM): For organic sludge, ETP sludge dewatering and food processing effluent.
• Non-Ionic Polyacrylamide (NPAM): For neutral pH applications and specialised industrial processes.
• Polydadmac: For primary coagulation in textile and dye effluent.
• Polyamine: For low-turbidity water and as a primary coagulant.

Typical Specifications

Specifications vary by polymer type and grade. Indicative ranges are given below. Final specification is confirmed for each application.

Parameter	Typical Value
Appearance	White to off-white powder / milky liquid
Type	Anionic / Cationic / Non-ionic polyacrylamide
Molecular Weight	5 – 20 million Daltons
Charge Density	10% – 50% (varies by product)
pH (1% solution)	4.0 – 8.0
Shelf Life	24 months from manufacture (powder)

Application and Dosage

Dosage depends on the suspension characteristics, suspended solids and dewatering equipment. Indicative ranges:

• ETP Primary Clarification: 1 – 5 ppm, based on suspended solids.
• Sludge Dewatering (Filter Press): 3 – 10 ppm, based on sludge type.
• Sludge Dewatering (Centrifuge): 4 – 12 ppm, based on sludge type and machine.
• Textile Effluent: 5 – 15 ppm, in combination with coagulant.
• Paper Mill White Water: 1 – 3 ppm for fibre recovery.

Exact dosage is confirmed after a jar test on your suspension sample. We work with your plant engineer or ETP operator to run the test and recommend the right polymer and dosage.

Preparation and Dosing

• Preparation: Dissolve powder in water at 0.1% – 0.5% concentration using a slow-speed stirrer (200-400 RPM).
• Aging: Allow the solution to age for 30 – 60 minutes before dosing.
• Dosing: Dose continuously through a metering pump into the effluent stream. Avoid high-shear mixing after dosing.
• Dilution: Further dilute to 0.05% – 0.1% at the dosing point for better dispersion.

Packing

• Powder Form: 25 kg bags and 50 kg bags.
• Liquid Form: 50 litre cans and 200 litre HDPE drums.
• Bulk Supply: 1000 kg jumbo bags available on request for large ETP plants.

Key Benefits

• Faster Settling: High molecular weight polymers settle solids quickly, reducing clarifier residence time.
• Drier Cake: The right polymer produces a drier filter cake, lowering sludge disposal cost.
• Lower Turbidity: Improves clarity of the treated water and reduces suspended solids in the outlet.
• Shear Stable: Flocs remain intact under turbulent flow in industrial pumps and pipes.
• Low Dosage: Effective at low ppm, reducing chemical cost per cubic metre of effluent.

Technical Support

Polymer selection is not a one-time decision. Suspension characteristics change with production, season and raw material. Our technical team reviews your suspension sample, current dosing and dewatering equipment, then recommends the right polymer and dosage. For Hyderabad ETPs, we provide on-site support for jar tests and trial runs.

Frequently Asked Questions

Q. Which polyelectrolyte is used for ETP sludge dewatering?
The choice depends on the sludge type. Cationic polyelectrolytes work well for organic sludge, while anionic polyelectrolytes are used for inorganic sludge and mineral suspensions. Final selection is confirmed after a jar test on your sludge sample.

Q. What is the difference between anionic and cationic PAM?
Anionic PAM carries a negative charge and is used for inorganic sludge, mineral processing and paper mills. Cationic PAM carries a positive charge and is used for organic sludge, ETP sludge dewatering and food processing effluent.

Q. What is the dosage of polyelectrolyte?
Dosage depends on the sludge characteristics and suspended solids. Typical ranges: ETP primary clarification 1-5 ppm, sludge dewatering 3-10 ppm. Final dosage is confirmed after a jar test on your sample.

Q. Do you supply polyelectrolyte in bulk to Hyderabad?
Yes, we supply in 25 kg bags and 50 kg bags. Bulk quantities are available for Hyderabad ETP plants and industrial units on request.
