FAQ

What is the Wastewater Dosing System 500L/H Desalination used for?

This system is designed to accurately inject treatment chemicals into water streams at a maximum flow rate of 500 liters per hour. Common application scenarios include feed and post-treatment dosing in small-to-medium desalination units, brine conditioning, pH control, antiscalant and corrosion inhibitor dosing, disinfection (biocide/chlorine) feed, and targeted chemical addition in industrial or municipal wastewater lines.

How do I install and start up the dosing system?

Install the unit on a stable, level surface near the chemical tank and the injection point. Connect suction and discharge tubing, secure the injection point with appropriate fittings, and ensure the unit is protected from freezing and direct sunlight. Connect to the specified power source and earth/ground properly. Prime the suction line to remove air, set the required dosing rate (or pulse/frequency), and run a controlled start-up test to confirm accurate flow and no leaks. For complex piping or local regulatory requirements, use a qualified technician.

What routine maintenance and checks are required?

Perform daily visual checks for leaks and chemical supply levels. Weekly: verify dosing rate and inspect tubing for wear. Monthly: clean strainers/filters, check fittings and clamps, and verify electrical connections. Every 3–12 months (depending on usage and chemical aggressiveness): inspect and, if needed, replace wear parts such as diaphragms, valves, and tubing. Keep records of calibrations and maintenance. Note that the 1-year warranty typically does not cover normal wear items, so keeping a spare set of consumable parts is recommended.

Which chemicals can be dosed with this system and are there compatibility limits?

The system is intended for common water-treatment chemicals such as acids and alkalis (pH adjustment), antiscalants, corrosion inhibitors, flocculants/coagulants, and oxidizing disinfectants (e.g., chlorine solutions). Chemical compatibility depends on the pump’s wetted materials—always consult the manufacturer’s compatibility chart. Avoid using undiluted strong oxidizers, solvents, or highly viscous/abrasive slurries unless the unit is specified for those media.

What should I do if the dosing rate is inaccurate or the unit stops working?

Basic troubleshooting: confirm chemical supply and suction line is not air-locked; check for clogged suction strainers or injection point; inspect tubing, valves, and fittings for leaks or wear; verify pump stroke/frequency settings and power supply; prime the pump and bleed air from the system. If the pump still under-delivers, replace wear parts (valves/diaphragm) and re-calibrate. If the problem persists, contact technical support with the model/serial number and maintenance history.

What does the 1-year warranty cover and how do I make a claim?

The 1-year warranty generally covers defects in materials and workmanship under normal use for one year from the date of purchase. It typically excludes consumables (diaphragms, valves, tubing), damage from misuse, improper installation, chemical corrosion if incompatible chemicals were used, and failures from lack of maintenance. To claim warranty, retain your proof of purchase and serial number, document the issue, and contact the supplier or manufacturer’s service center. Follow their instructions for return authorization; do not attempt unauthorized repairs if you intend to claim warranty.
