What it Does
Where our
Solutions Work
Blue-White® provides precise chemical metering systems for sludge conditioning, thickening, and dewatering processes in municipal wastewater treatment. Our peristaltic and diaphragm pumps, flow meters, and chemical feed systems help operators improve solids capture, reduce hauling costs, and stabilize biosolids for disposal or reuse.
Precision Dosing
Why Solids Management Matters
Sludge generated during wastewater treatment represents a major operational and financial challenge for utilities. Proper solids handling impacts:
- Biosolids quality and disposal options
- Operating costs tied to hauling, drying, or incineration
- Odor and corrosion control
- Overall plant efficiency and permit compliance
Chemical dosing is key in conditioning sludge to reduce water content, improve dewatering performance, and stabilize volatile compounds. Accurate, repeatable dosing is critical for consistent results—especially as solids characteristics vary daily.
Treatment Applications
Common Chemical
Applications
Sludge Handling & Solids Management processes require accurate dosing for:
Polymer Dosing for Dewatering
- Inject high-viscosity emulsions into belt presses, centrifuges, or screw presses
- Optimize floc formation for better cake dryness and reduced filtrate TSS
- Adjust feed rates in response to solids loading and plant flow
Sludge Thickening
- Use polymers to improve gravity thickening or dissolved air flotation (DAF) performance
- Support downstream digesters or drying beds by concentrating sludge before transfer
Stabilization & Conditioning
- Dose lime or ferric chloride to raise pH or reduce odor-causing compounds
- Treat biosolids prior to hauling or land application
- Support pathogen reduction and vector attraction control
Applications benefit from automated, flow-paced chemical metering that adjusts to load changes and operating conditions.

The Blue-White Solution
Solutions for
Solids Handling
Our chemical feed systems are built to handle thick, abrasive, and shear-sensitive fluids in challenging sludge environments—without clogging or excessive wear. FLEXFLO® peristaltic pumps provide smooth, low-shear metering for high-viscosity polymers with a single, easy-to-replace tube, while CHEM-FEED® diaphragm pumps deliver steady, pulse-free flow for coagulants and less viscous additives with long-lasting DiaFlex diaphragms. Paddlewheel and ultrasonic flow meters monitor dilution or polymer feed water and pace chemical dosing based on flow volume or batch cycles, with full SCADA and dosing control compatibility.
Fully integrated chemical feed panels and skids are designed for polymer injection and include calibration columns and containment, with options for single or dual polymer lines in thickening or dewatering systems. Built with chemical-resistant materials and rugged enclosures, these compact systems support 24/7 operation in high-solids, corrosive, and humid environments, with leak detection, flow verification, and programmable alarms for safe performance. The result is improved sludge thickening and dewatering, drier cake and reduced hauling costs, less chemical waste through precise dosing, faster maintenance with fewer shutdowns, and enhanced odor control and biosolids quality.
