Coagulation & Flocculation in Municipal
Wastewater Treatment
What it Does
Where our
Solutions Work
Blue-White® delivers dependable chemical metering systems for coagulation and flocculation processes in municipal water and wastewater applications. Whether you’re clarifying surface water for drinking or thickening sludge for dewatering, our pumps, flow meters, and feed skids provide the accuracy and reliability required for consistent solids removal and process efficiency.
Precision Dosing
Why Coagulation & Flocculation Matters
Coagulation and flocculation are key treatment steps that drive the removal of suspended solids, turbidity, color, and organic material. By introducing chemicals that bind fine particles together, utilities can:
- Improve sedimentation and filtration performance
- Reduce chemical demand downstream (e.g., chlorine or carbon)
- Minimize TSS and BOD in effluent
- Support sludge dewatering and biosolids management
Accurate and consistent chemical feed is critical; under- and overdosing can result in poor water clarity, permit exceedances, or increased sludge volumes.
Treatment Applications
Applications in
Water & Wastewater Treatment
Nutrient Removal processes require accurate dosing for:
Drinking Water Clarification
- Inject alum, ferric chloride, or sodium aluminate ahead of sedimentation or filtration
- Remove naturally occurring organic matter (NOM), turbidity, and color from surface water sources
- Stabilize pH and improve filter run times
Wastewater Primary & Secondary Treatment
- Dose coagulants and polymers before clarifiers to improve solids removal
- Improve thickening in gravity thickeners and dissolved air flotation (DAF) units
- Support tertiary treatment goals by improving suspended solids removal upstream
Sludge Conditioning for Dewatering
- Inject high-viscosity polymers into belt presses, centrifuges, or drying beds
- Improve cake dryness and reduce hauling costs
Applications benefit from automated, flow-paced chemical metering that adjusts to load changes and operating conditions.

The Blue-White Solution
Solutions for
Coagulation & Flocculation
Our equipment is designed to handle the chemical and physical demands of solids removal applications. FLEXFLO® peristaltic pumps are ideal for high-viscosity or shear-sensitive polymers, while CHEM-FEED® diaphragm pumps provide steady, reliable flow for alum, ferric, and other inorganic coagulants. Adjustable flow rates, wide turndown ratios, and tool-less maintenance help reduce operator workload. Paddlewheel and ultrasonic flow meters pace chemical feed to plant flow, while variable area flow meters provide clear visual verification in treatment skids or chemical rooms. Modular, pre-assembled feed skid systems support multi-chemical dosing points and offer compact, customizable designs with local or SCADA-integrated controls for centralized basins or distributed clarifiers.
Built for reliability in demanding environments, the systems handle aggressive and viscous chemicals and feature NEMA 4X enclosures for corrosion resistance and outdoor or washdown use. Optional flow verification and leak detection support critical process control and 24/7 municipal operations. Utilities benefit from more consistent solids removal, improved treatment efficiency, and reduced chemical consumption due to accurate dosing. These systems also help minimize downstream issues such as filter fouling, odor, and effluent violations while reducing manual oversight and speeding maintenance turnaround.
