Chemical Dosing Skid for Air Scrubbers

The Chemical Dosing Skid for Air Scrubbers is a packaged chemical feed unit designed to support wet air cleaning systems in pig houses, manure processing areas, and other livestock facilities. It meters the specified treatment chemical into a scrubber sump or recirculation line according to the selected control strategy. Pumps, pipework, valves, instruments, and controls can be arranged on a compact frame for convenient integration with new steel structure livestock buildings or existing exhaust air treatment systems.

• Modular layout tailored to the scrubber process, chemical, and available plant-room space.
• Metering pump selection and wetted materials matched to the specified chemical concentration and duty.
• Optional duty/standby pumps, level monitoring, leak detection, and local alarms for commercial farm operation.
• Accessible valves and pump heads to simplify inspection, calibration, and routine service.
• Preassembled pipework and electrical components can reduce on-site installation work.

A project-specific package may include a corrosion-resistant skid frame or mounting panel, chemical storage or day tank, suction assembly, diaphragm metering pump, calibration column, isolation and non-return valves, pressure relief or back-pressure devices, discharge pipework, and an injection assembly. A containment tray, splash protection, tank level switch, pH or ORP instrumentation, and control cabinet can be specified where required.

The metering pump draws chemical from the storage vessel and delivers a controlled dose to the designated point in the scrubber liquid circuit. Depending on the scrubber design, pump output may be set manually or adjusted using a pH, ORP, flow, or other process signal. The chemical mixes with the recirculating liquid while the scrubber treats the exhaust air. The dosing skid supports this process; final air-cleaning performance depends on the complete scrubber design and operating conditions.

• Chemical wet scrubbers serving mechanically ventilated commercial pig houses.
• Exhaust air treatment for manure reception, separation, and processing buildings.
• Odor control systems associated with livestock wastewater treatment areas.
• New-build and retrofit livestock construction projects requiring a compact chemical feed package.

The skid layout, tank arrangement, pump redundancy, injection points, instrument package, containment provisions, and control interface can be customized. Material selection should be confirmed against the chemical safety data, concentration, operating temperature, and scrubber supplier's process requirements. Layout drawings and connection positions can be coordinated with the pig house ventilation design and steel structure building services.

Position the skid on a level, accessible base near the scrubber system, with suitable chemical storage, containment, ventilation, and service clearance. Secure the frame and connect the chemical supply, injection line, power, and control signals according to the approved project drawings. During commissioning, verify line integrity, pump calibration, interlocks, and sensor operation. Routine maintenance includes checking tank level, inspecting tubing and valves for leaks, cleaning sensors, and servicing the metering pump in accordance with its manual.

Can the skid connect to an existing air scrubber?
Yes, subject to a review of the injection point, pipework, control signals, chemical specification, and available installation space.

Is automatic dosing available?
Yes. The control method can be configured around suitable process feedback, such as pH or ORP, where required by the scrubber design.

What information is needed for a quotation?
Provide the scrubber process description, chemical and concentration, required dosing duty, injection pressure, site power supply, control requirements, and installation layout.
