Chemical Dosing Purpose

Process streams require chemical treatment for corrosion inhibition, pH control, scale prevention, or performance enhancement. Blue toner systems meter chemicals accurately maintaining target dosing rates despite flow variations ensuring consistent treatment.

Package Components

Chemical storage tank with level monitoring, metering pump with adjustable stroke or speed, injection point assembly with quill or diffuser, pulsation dampener smoothing flow, pressure relief protection, flow verification, control panel managing operation. Integrated skid ready for installation.

Dosing Control

Flow-proportional dosing adjusts chemical feed based on process flow maintaining constant ratio. Fixed-rate dosing for constant treatment applications. Feedback control from analyzers optimizes dosing based on measured parameters.

Pump Technology

Diaphragm metering pumps provide accurate dosing with chemical isolation. Piston pumps for higher pressures. Peristaltic pumps for low flow rates or abrasive chemicals. Selection depends on chemical properties, pressure, and flow range.

Operating Pressure

Pump discharge pressure overcomes injection point pressure plus piping losses typically 50-500 psig. Positive displacement design maintains accuracy across pressure variations. Pulsation dampeners protect instrumentation.

Material Selection

Chemical-resistant construction throughout. Polyethylene or fiberglass tanks. Pump wetted parts compatible with treatment chemical. Injection tubing and fittings resist chemical attack. Design prevents material degradation.

Applications

Boiler water treatment chemical injection, cooling water biocide and inhibitor dosing, wastewater pH adjustment, polymer and coagulant addition, corrosion inhibitor injection, and any process requiring controlled chemical addition.

Flow Verification

Flowmeters or stroke counters verify chemical delivery. Low-flow alarms indicate pump problems. Totalizers track chemical consumption for inventory management. Verification ensures proper treatment levels.

Safety Features

Containment for chemical spills. Ventilation for volatile chemicals. Emergency shutdown capability. Proper labeling and material identification. Installation per chemical handling safety standards.

Integration

Interfaces with process control systems receiving flow signals and providing status feedback. Remote monitoring enables centralized chemical management. Automated operation reduces labor requirements.

Performance Benefits

Provides accurate chemical dosing maintaining treatment effectiveness. Automated operation ensures consistency. Reduces chemical waste through precise control. Simple proven dosing technology.

Construction Standards

Pressure equipment per applicable codes. Chemical compatibility verified. Electrical systems for area classification if required. Complete documentation with dosing calculations and safety information.
