FAQ

What is the Wastewater Powder Chemical Dosing Device 500L/h used for?

It is designed to prepare and accurately dose powdered treatment chemicals into wastewater systems at flow capacities up to 500 L/h (slurry/dosing solution) for processes such as coagulation/flocculation, pH correction, decolorization, heavy metal precipitation, odor control, sludge conditioning and pre-treatment for filtration or dewatering.

Which powdered chemicals can I use with this machine?

Common compatible powders include polymers (PAM), polyaluminium chloride (PAC), activated carbon, hydrated lime and many flocculants/coagulants. Do not use explosive, highly hygroscopic, or reactive powders without consulting the manufacturer. For strongly corrosive or unusually coarse/powdery materials, confirm compatibility and recommended feed settings before use.

How do I calculate the dosing rate I need to set?

Use: required powder (kg/h) = target dose (mg/L) × wastewater flow (m3/h) / 1000. Example: for 10 mg/L on a 10 m3/h stream: 10 × 10 / 1000 = 0.1 kg/h (100 g/h). If the device makes a slurry, convert that solid feed into slurry flow using the slurry concentration (kg solids per L slurry) to select pump and settings. Always run a short pilot test and calibrate the machine to verify actual feed rates.

What are the key installation and operating considerations?

Install on a stable, level foundation near the chemical storage to minimize powder transfer distance. Provide proper dust containment and ventilation, grounding for electrical safety, and access for maintenance. Use hopper agitation or vibrators and level sensors to prevent bridging. Integrate the controller with plant PLC or 4–20 mA signals if automatic control is needed. Always wear appropriate PPE and follow local safety and handling rules for powders.

What routine maintenance is required to keep the unit reliable?

Daily/weekly: check hopper for bridging, verify feed continuity, inspect nozzles/lines for blockages, and confirm alarms and level sensors. Monthly: inspect screws, wear plates and bearings, clean slurry tanks and strainers, and check seals and piping. Replace consumables (filters, seals) per the manufacturer’s schedule. Keep powders dry and clean the hopper before switching chemicals to avoid cross-contamination.

What does the 1-year warranty cover and what are common troubleshooting steps?

The 1-year warranty typically covers manufacturing defects in materials and workmanship; consumables (seals, filters, wear parts), damage from misuse, improper installation, chemical corrosion, or unauthorized modification are usually excluded. Common problems: powder bridging (add vibrator/agitator, check humidity), inconsistent feed (recalibrate screw speed, inspect wear), pump cavitation or low slurry output (check suction, inlet strainer, prime), and electrical faults (check fuses, motor overload). Contact the supplier with serial/model details for warranty service and technical help.
