FAQ

What is the Wastewater Dosing Unit SS/PP 500L/h and what kinds of applications is it used for?

The unit is a chemical dosing system built with stainless steel (SS) and polypropylene (PP) wetted parts, sized to dose up to 500 liters per hour. Typical applications include municipal and industrial wastewater treatment (pH correction, neutralization), disinfection (chlorine dosing), coagulation/flocculation (polymers, coagulants), odor control, sludge conditioning, cooling-tower or process-water treatment, and small-to-medium treatment plants in food, textile, carwash, and manufacturing facilities.

Which chemicals can I safely dose with this SS/PP unit?

SS/PP construction makes the unit compatible with a wide range of aqueous chemicals such as acids (for pH correction), alkalis, many polymer formulations, coagulants, and common disinfectants. However, compatibility depends on concentration and temperature. Strong oxidizers, aggressive solvents, or high-concentration acids may attack components—check the manufacturer’s chemical compatibility chart or provide the exact chemical name, concentration and temperature before use. When in doubt, contact the supplier for confirmation.

How do I install and set up the dosing unit for typical wastewater use?

Mount the unit on a stable, level surface close to the chemical feed point and within reach of electrical supply and drain. Connect inlet/outlet hoses with proper fittings and check valves, provide secondary containment for the chemical tank, and route vent lines safely. Prime and bleed the pump according to the manual, set the dosing rate (do not exceed the 500 L/h maximum), and calibrate the output using a measured volume over time. Start at a low dose and increase while monitoring process parameters (pH, residual chlorine, turbidity) to reach the required treatment target.

What routine maintenance is required to keep the dosing unit reliable?

Perform visual checks daily for leaks, hose condition and chemical levels. Weekly: inspect fittings, valves and strainers; ensure venting and containment are clear. Monthly: check pump performance, tubing, and non-return valves; verify dosing calibration. Replace wear items (seals, diaphragms, tubing) per the manufacturer's recommended intervals or sooner if performance drops. Flush and neutralize tanks and feed lines before long shutdowns and winterize if freezing is possible. Keep service records and schedule an annual inspection.

What safety precautions should I follow when operating this dosing unit?

Always use appropriate PPE (gloves, goggles, face shield, aprons) when handling chemicals or accessing tank internals. Ensure proper labeling, secondary containment, spill control kits, and good ventilation. Never mix chemicals in the dosing tank unless specifically recommended. Follow SDS instructions for each chemical, and ensure emergency eyewash/shower access. Train personnel on safe handling, isolation/lockout procedures, and emergency response for spills or exposure.

What does the 1-year warranty cover and what steps should I take if there’s a problem?

The one-year warranty typically covers manufacturing defects in materials and workmanship under normal use. It usually excludes normal wear parts (seals, diaphragms, tubing), damage from misuse, chemical incompatibility, improper installation, and unauthorized repairs. To file a claim, retain proof of purchase, note the unit serial/model number, document the issue (photos, operating conditions) and contact the supplier or manufacturer support. Follow their instructions for troubleshooting, repair authorization, and return shipping—keep spare parts (e.g., seals and tubing) on hand to minimize downtime.
