What it Does
Where our
Solutions Work
Blue-White® provides accurate, dependable chemical metering solutions for disinfection processes in municipal water and wastewater systems. Whether dosing sodium hypochlorite in a drinking water facility or using peracetic acid for effluent disinfection, our chemical metering pumps, flow meters, and feed systems help operators maintain effective microbial control while managing cost and safety.
Precision Dosing
Why Disinfection Matters in Public Water Systems
Disinfection is one of the most important steps in protecting public health. In water treatment, disinfectants eliminate harmful pathogens such as E. coli, Giardia, and Cryptosporidium before water reaches consumers. Disinfection in wastewater reduces microbial loading before treated effluent is discharged to rivers, lakes, or reuse systems.
But chemical disinfection comes with challenges:
- Overdosing can result in disinfection byproducts (DBPs) like trihalomethanes
- Underdosing puts public health and compliance at risk
- Off-gassing, corrosive chemicals require safe and consistent handling
- Fluctuating flow rates demand responsive, automated feed systems
Accurate, repeatable chemical metering is critical to keeping treatment systems balanced, safe, and effective.
Treatment Applications
Common Disinfection
Applications
Disinfection processes require accurate dosing for:
Potable Water Treatment
- Sodium hypochlorite injected post-filtration
- Maintain chlorine residuals in distribution lines
- Flow-paced dosing based on plant influent or storage tank levels
Wastewater Effluent Disinfection
- Sodium hypochlorite or peracetic acid (PAA) dosing after secondary treatment
- Applied just before discharge to reduce coliforms and meet permit limits
- Compatible with ultraviolet (UV) systems to boost effectiveness
Reuse & Recycled Water
- Disinfection before irrigation, industrial reuse, or groundwater recharge
- Requires high accuracy and monitoring to protect downstream users
SCADA-Integrated Facilities
- Pumps and meters must respond to real-time flow data, tank levels, and chlorine residual monitoring
- Redundancy and alarms help prevent system failures
Applications benefit from automated, flow-paced chemical metering that adjusts to load changes and operating conditions.

The Blue-White Solution
Solutions for Wastewater
Disinfection
Blue-White’s lineup of pumps, flow meters, and turnkey feed systems is engineered to meet the demanding challenges of disinfection in both water and wastewater treatment plants. Our FLEXFLO® peristaltic metering pumps are specifically designed to handle off-gassing chemicals such as sodium hypochlorite without vapor lock, while our CHEM-FEED® diaphragm pumps deliver consistent, pulse-free flow ideal for flow-paced dosing. Built with long service intervals and chemical-resistant materials, our solutions reduce operator burden and maintenance demands. Flow verification and control are supported through our paddlewheel and ultrasonic flow meters, along with variable area flow meters (rotameters) for simple visual monitoring. With SCADA-ready 4–20 mA and pulse output options, our systems integrate seamlessly into existing control platforms. For facilities seeking streamlined implementation, our pre-plumbed and factory-tested skid systems provide compact, rapid integration—ideal for packaged plant expansions, pilot systems, or standardizing chemical feed platforms.
Designed with safety and performance at the forefront, our systems minimize leak points by eliminating valves and seals in the fluid path of our peristaltic pump designs. Our Tube Failure Detection technology automatically stops the pump and triggers an alarm in the event of a leak, adding an extra layer of protection. Housed in durable NEMA 4X/IP66 enclosures, our equipment resists corrosion and supports reliable outdoor installation, even when handling off-gassing, corrosive, and oxidizing disinfection chemicals. The result for operators and utilities is reduced chemical exposure risk, stable chlorine residuals throughout the distribution network, fewer compliance violations or DBP formation issues, minimized downtime from vapor-locking or clogging, and predictable chemical usage that lowers overall operating costs.
