FAQ

What is a Detergent Circulation Water Volumetric Dosing System, Auto and where is it typically used?

It is an automated dosing system that measures and injects precise volumes of detergent into circulation water systems using volumetric metering (flow meters or positive displacement pumps). Typical applications include industrial laundries, food and beverage CIP lines, breweries, pharmaceutical cleaning, car washes, and any process requiring consistent detergent concentration in recirculating wash or cleaning water.

How does the volumetric dosing function work in circulating water systems?

The system uses a flow meter or a calibrated volumetric pump to deliver a set ratio of detergent per volume of water circulated. It monitors water flow or time and injects detergent proportionally, maintaining a target concentration automatically as water flow or cycle length changes. Some systems add feedback from conductivity or concentration sensors for closed-loop control.

What types of detergents and chemicals are compatible with this system?

Most alkaline, acidic, and neutral liquid detergents formulated for CIP and process cleaning are compatible, provided their chemical compatibility matches the pump, seals, tubing, and materials of construction (typically PE, PP, PVDF, PTFE, and stainless steel). Avoid undiluted solvents, highly viscous pastes, or solids without confirming manufacturer compatibility and viscosity limits.

How is the system installed and integrated into existing circulation lines?

Installation usually involves mounting the dosing pump and control module near the circulation loop, connecting the dosing line to the return or injection point, and linking the water flow signal or flow sensor to the controller. Electrical power, a suction line from the chemical tank, and optional concentration sensors, alarms, and remote communications are also connected. Commissioning includes setting dosing ratios and verifying injection points to ensure proper mixing.

What routine maintenance and calibration does the automatic volumetric dosing system require?

Regular tasks include checking and cleaning strainers/filters, inspecting and replacing pump tubing or diaphragms at recommended intervals, verifying and calibrating flow meters and volumetric pumps, checking for leaks, and verifying concentration using conductivity or sampling. Follow manufacturer schedules for preventive maintenance to retain accuracy and extend component life.

What common problems occur and how can they be troubleshooted?

Common issues: underdosing from air in suction lines, clogged suction filters, worn pump tubing, or incorrect flow meter signals — remedy by priming lines, cleaning filters, and replacing tubing. Overdosing may be caused by misconfigured dosing ratios or sensor errors — check controller settings and sensor calibration. Alarms for low tank level, pump fault, or communication errors usually indicate supply or electrical issues; inspect tank level switches, wiring, and connectors. If unsure, consult the system manual or vendor support.
