What it Does

Where our
Solutions Work

Blue-White® provides reliable chemical metering and monitoring systems for odor control in wastewater collection and treatment facilities. From lift stations to headworks and biosolids handling, our pumps, flow meters, and feed skids help mitigate hydrogen sulfide and other odor-causing compounds that threaten community relations, compliance, and infrastructure integrity.

Precision Dosing

Why Odor Control Matters in Wastewater Operations

Odors in municipal systems are more than just a nuisance, they’re a sign of hydrogen sulfide (H₂S) generation, anaerobic conditions, and potentially corrosive gas exposure that can damage infrastructure and trigger public complaints. Common sources include:

  • Force mains and gravity sewers
  • Lift stations and wet wells
  • Primary clarifiers and digesters
  • Sludge handling and dewatering systems

Odor control strategies often require continuous or flow-paced chemical dosing, and success depends on delivering the right amount of chemical at the right location and at the right time.

Treatment Applications

Common Chemical
Applications

Odor Control processes require accurate dosing for:

Hydrogen Sulfide Mitigation


  • Inject nitrate-based oxidizers, hydrogen peroxide, or magnesium hydroxide into gravity sewers or force mains
  • Control H₂S generation at the source to avoid downstream odor and corrosion

Surface Odor Suppression


  • Spray chlorine-based solutions or surfactant blends over tanks, lagoons, or sludge piles
  • Manage odor release from headworks, digesters, or dewatering bays

Biosolids & Sludge Handling


  • Dose alkaline stabilizers, iron salts, or polymers to reduce volatile organic compound (VOC) emissions
  • Improve odor profile during hauling and land application

Applications benefit from automated, flow-paced chemical metering that adjusts to load changes and operating conditions.

The Blue-White Solution

Solutions for
Odor Control

Our chemical feed systems are built for remote, outdoor, and highly corrosive environments, making them ideal for wastewater odor control applications that demand reliability and low maintenance. FLEXFLO® Peristaltic Pumps handle abrasive, high-viscosity chemicals like magnesium hydroxide with smooth, clog-free performance, while CHEM-FEED® Diaphragm Pumps deliver consistent dosing of oxidizers and disinfectants. Paddlewheel and ultrasonic flow meters support accurate, flow-paced dosing, optimize chemical usage, and offer compact, SCADA-compatible integration for real-time monitoring.

Our modular, pre-wired chemical feed skids are designed for lift stations, wet wells, and headworks, with options for single or multiple dosing points. Available features include containment, leak detection, and high-visibility displays. With IP66/NEMA 4X-rated enclosures, corrosion-resistant materials, and compact footprints, these systems are engineered for continuous 24/7 operation in harsh environments with minimal maintenance.
