Three actions. One molecule. A branched 3D carboxylic–sulfonated terpolymer that outperforms conventional linear polymers by 3–5× — TGA-validated to 150°C, phosphorus-free, OECD 301B biodegradable.
Conventional antiscalants are linear homopolymers that operate by a single mechanism and degrade above 80°C, releasing orthophosphate that creates a new scale problem. Coeus formulations are branched 3D carboxylic–sulfonated terpolymers — architecturally engineered for multi-point mineral binding at sub-stoichiometric concentrations, with a TGA-validated thermal ceiling of 150°C continuous.

Every Coeus terpolymer delivers all three scale-elimination mechanisms simultaneously from a single dosing point — threshold inhibition in early effects, crystal modification in mid-effects, electrosteric dispersion throughout.
| Scale Thickness | Efficiency Loss | Annual Cost Impact |
|---|---|---|
| 0.5 mm CaCO₃ | ~4% loss | ₹25–40 L |
| 1.0 mm CaCO₃ | ~8% loss | ₹50–80 L |
| 2.0 mm CaCO₃ | ~15% loss | ₹90 L–1.2 Cr |
| 3.0 mm mixed | >25% loss | ₹1.5–3 Cr |
For a 2,500 TCD sugar mill operating a 150-day crushing season with uncontrolled evaporator scaling, compounded fuel, acid, labour, and production losses reach ₹2.5–4.5 crore annually. CPAS-1.0 recovers these margins systematically — ROI payback: 3–6 months.
Seven precision-engineered formulations covering every water treatment challenge in industrial processing — from 3 ppm membrane antiscalant to 60 ppm oxygen scavenger. Each carries a batch-specific Certificate of Analysis.
Engineered for the thermal extremes of sugar evaporation — triple-action scale control across all effects, juice heaters, and vacuum pans. Zero phosphorus. Globally certified. Campaign-proven for 21+ days between CIP cycles.
CPAS-1.0 is Coeus Polylabs' flagship food-grade antiscalant — a high-purity carboxylic sulfonated terpolymer engineered for the demanding thermal environments of sugar evaporation. It delivers triple-action scale control while simultaneously meeting FSSAI, FDA 21 CFR 173.310, EU Reg. 1333/2008, JECFA, and NSF/ANSI 60. Zero phosphorus. Zero heavy metals. Verified on every batch by ICP-OES/MS analysis.
As clarified juice concentrates from 15° Brix to 65° Brix across five effects, calcium oxalate (CaOx), CaCO₃, CaSO₄, and silica exceed their solubility limits and precipitate on calendria tube walls. A 1 mm CaOx layer reduces heat transfer efficiency by 15–22%, directly increasing bagasse consumption and cutting campaign length. For a 2,500 TCD mill over 150 crushing days, uncontrolled scaling causes ₹2.5–4.5 crore in compounded losses.
Polyacrylate chains adsorb onto pre-nucleation mineral clusters at sub-stoichiometric concentrations (2–20 ppm), disrupting crystal formation before nucleation begins. Prevents scale initiation in 1st and 2nd effects where supersaturation is highest. Branched 3D architecture delivers 3–5× inhibition efficiency vs linear polymers at identical dosage.
Polymer chains incorporate into CaOx and CaCO₃ crystal lattices producing distorted, soft, non-adherent polymorphs — vaterite instead of calcite. Deposits remain loose and non-adherent, removed during blowdown without acid wash. PDI 2.0–3.5, precision-controlled for batch consistency.
Charged sulfonated groups envelop suspended particulates, creating a repulsive electrostatic barrier (zeta potential −35 to −55 mV) that prevents agglomeration on heat-transfer surfaces throughout all five effects simultaneously. Silica control up to 320 mg/L SiO₂ — critical for high-silica South Indian borewell feeds.
| Equipment | Primary Scale | Temperature |

| 1st Effect MEE | CaCO₃, early CaOx | 110–120°C |
| 2nd–3rd Effects | CaOx (Whewellite) | 80–105°C |

CPBA-3.0 is an advanced multi-functional boiler water treatment chemical for industrial boilers at 5–100+ kg/cm². It combines scale inhibition, sludge conditioning, corrosion passivation, and oxygen scavenging support in one precision-dosed liquid. A 1 mm CaCO₃ scale layer reduces heat transfer by 7–9%. A 3 mm mixed deposit causes under-deposit corrosion costing ₹1.5 crore+ per tube failure incident.
Polymer chains adsorb onto pre-nucleation mineral clusters preventing CaCO₃, CaSO₄, Mg(OH)₂, SiO₂, and iron oxide deposition. Threshold-active at 5–20 ppm feedwater — effective 5–100+ kg/cm² to 180°C.
Converts hard adherent scale into soft, free-flowing sludge precipitates that stay suspended and are removed via scheduled blowdown — eliminating acid wash requirements between planned shutdowns.
Polymer film passivates iron and steel surfaces, raising corrosion potential and suppressing under-deposit attack. <1 mpy documented corrosion rate on carbon steel in treated boiler water.
Synergistic reduction aid complements CPOS-4.0 during fluctuating load conditions — provides additional protection when deaerator performance drops during startups and load transients.

CPRO-2.0 is precision-engineered at 4,000 Da — the molecular weight that enables maximum diffusion through the concentration polarisation boundary layer at the RO membrane surface. Conventional antiscalants (6,000–15,000 Da) cannot penetrate this layer, where local supersaturation is 4–6× higher than bulk feed chemistry.
South Indian feedwaters present particular challenges with borewell silica typically 80–180 mg/L. CPRO-2.0 maintains silica up to 320 mg/L in concentrate, enabling 80–90% recovery rates impossible with conventional products.
4,000 Da chains penetrate the concentration polarisation layer, intercepting CaCO₃, CaSO₄, BaSO₄ pre-nucleation clusters at the actual membrane surface. Stable at LSI values up to +3.0 — far beyond the +0.5–1.5 conventional antiscalant limit.
Low-MW chains incorporate into scale crystal lattices producing soft, non-adherent polymorphs that flush during backwash without membrane abrasion. Zero flux decline at 10× recommended dosage (ASTM D6908 coupon test).
Specialised sulfonated groups form stable complexes with silanol (Si-OH) groups — preventing SiO₂ polymerisation and maintaining dissolved silica to 320 mg/L in concentrate. The most critical and irreversible RO fouling mechanism — controlled.

pH 2.5–4.0 as supplied (acidic). Always dilute before use. Wear nitrile gloves. Avoid freezing — thaw completely and mix well before use. Do not overdose — excess can coat membrane surface.
At concentrations as low as 10–20 ppb, dissolved oxygen initiates an electrochemical pitting cascade on boiler tube walls: Fe → Fe²⁺ + 2e⁻. Pitting creates microscopic craters that deepen every operational hour. Mechanical deaeration alone reduces DO to 20–40 ppb — still dangerously above the safe threshold. CPOS-4.0 chemically removes this residual within 30 seconds.

|---|---|---|
| O₂ Scavenging | Sulphite oxidation chain | DO <5 ppb in feedwater |
| Condensate Protection | CO₂ acid neutralisation | Prevents condensate pitting in return lines |

Dosing Point: Deaerator storage tank or feedwater pump suction line. Motor diaphragm pump (0–5 LPH). Ensure mixing before economiser inlet.
Target Residual: 20–30 ppm SO₃ in boiler water (test twice daily).

Maintaining boiler water pH between 8.5 and 9.7 is critical. Below 8.5: general and pitting corrosion accelerates, iron pickup contaminates product (sugar ICUMSA colour, pharma batch purity). Above 10.0: caustic embrittlement, silicate scaling, and foaming destroy tubes. A ±0.5 pH deviation increases corrosion rate by 2–3×. CPPH-5.0 delivers ±0.2 pH control.

CPDS-7.0 is a high-MW, strongly anionic carboxylate-sulfonate copolymer at 280–380 cP viscosity (3× conventional dispersants) — maintaining iron oxide, calcium phosphate, silica, and organic debris in permanent colloidal suspension. Used as a Pan Aid in vacuum crystallisers and as an Iron Oxide Dispersant in boiler condensate circuits.
90% of boiler tube failures in sugar mills start with particles that settled. CPDS-7.0 removes this threat entirely by holding particles permanently in suspension until removed via blowdown.
Carboxylate-sulfonate chains adsorb onto particle surfaces imparting high negative charge (−35 to −55 mV zeta potential). Particles cannot agglomerate or settle — even in low-flow zones of pan body and mud drum where conventional dispersants fail.
Long high-MW polymer chains extend from particle surfaces creating a physical spacer barrier. Particles cannot approach close enough to bond — robust under changing massecuite pH and sucrose concentration. High viscosity (280–380 cP) maintains effectiveness in low-velocity zones.
Excess polymer forms a hydrophilic film on pan walls and boiler tube surfaces making surfaces less adhesive to particles. Reduces blowdown iron from 8–12 ppm to <2 ppm — directly protecting ICUMSA colour score and preventing export-grade sugar rejection.
Batch Pan: Slug dose at 75% pan filling capacity — reduces surface tension and boosts thermal circulation. 10–30 ppm on massecuite weight.
Continuous Pan: Uniform metering via calibrated pump across all feeding compartments. Benefits: 15–25 minutes reduction in boiling time per strike, improved molasses exhaustion, better ICUMSA colour.
3–8 ppm into boiler condensate return line. Prevents iron oxide agglomeration and carryover into the evaporator train. Blowdown iron reduced from 8–12 ppm to <2 ppm.

Anionic polymer — incompatible with cationic surfactants (never mix). Store at 5–40°C. Avoid freezing — polymer structure may be permanently damaged. Viscous — use adequate pump suction capacity.
Multiple-effect evaporators, juice heaters, and vacuum pans operate at the extreme edge of solubility curves. One week of uncontrolled scale costs more than a full season of treatment. Our CPAS-1.0 and CPDS-7.0 were engineered specifically for these conditions — food-grade, FDA/FSSAI compliant, and verified across Indian crushing seasons.

Coeus Polylabs was founded on a simple conviction: water treatment chemistry must protect the water system it serves, not pollute it. Every formulation decision — every monomer selected, every functional group added — is evaluated against a sustainability checklist before it enters a batch.
All seven products contain <1 ppm total phosphorus, independently verified by ICP-OES per batch. No phosphonate builders. No ATMP. No HEDP. ZLD-compliant and CPCB eutrophication-free.
OECD 301B certification — ≥60% BOD in 28 days. Our terpolymer backbone is designed for enzymatic degradation. Meets EU BPR and Indian ETP discharge standards without neutralisation treatment.
CPCT-6.0 enables 7–10 cycles of concentration vs industry-average 3–4, reducing cooling tower blowdown by 40–50%. At a 2,500 TCD sugar mill, this saves 8–12 ML of process water per season.
As, Pb, Cr, Cd total <5 ppm; individual metals <1 ppm per ICP-MS. No chromate-based corrosion inhibitors. Compatible with Food Safety Authority discharge requirements across all states.
Our Cherlapally facility operates under Zero Liquid Discharge consent from TSPCB. All process effluent is treated on-site. No wastewater to sewer. TSPCB Consent to Operate maintained in good standing.
CPAS-1.0 scale prevention recovers 8–12% bagasse efficiency per season at a reference sugar mill — equivalent to 3,200–4,800 tonnes of additional bagasse fuel saved, reducing direct CO₂ from combustion.
