FAQ

What is the "Automatic PAM Dosing 500L/hr Desalination" system and in which application scenarios is it used?

This is an automatic polyacrylamide (PAM) dosing and make‑up system designed for water treatment tasks in desalination and related industries. It prepares and doses polymer solution to aid flocculation, solids capture and sludge conditioning. Typical applications include RO pretreatment and clarification for seawater/brackish desalination, intake and pre‑sedimentation plants, industrial wastewater pretreatment, sludge dewatering (centrifuges/filters/presses), and aquaculture solids removal. The "500 L/hr" designation refers to the system’s maximum prepared polymer solution throughput or dosing solution supply rate, suitable for small to medium pretreatment trains.

How do I prepare PAM solution for use with this unit and what concentrations should I use?

PAM can be used either as a dry powder or as a liquid formulation. Typical make‑up concentrations for automatic systems are low (commonly 0.05–1.0% w/w depending on polymer type and molecular weight). A common starting point: 0.1–0.5% polymer solution for cationic/anionic PAM. Always add polymer slowly into well‑agitated water (or use the system’s in‑line mixer) to avoid lumping; allow adequate hydration (typically 15–60 minutes depending on polymer) and keep gentle mixing to prevent shear degradation. Perform a jar test to determine optimum concentration and dosing for your water quality. Use PPE (gloves, goggles, dust mask) when handling dry polymer.

How do I determine and control the correct dosing rate for my desalination pretreatment?

Start by performing jar tests to find the optimum active polymer dose (commonly in the range 0.1–5 mg/L active polymer, depending on turbidity and solids). Measure your process flow and convert the required mg/L into volumetric dosing of your prepared solution. Use the system’s adjustable metering pump or flow controller to set the output. Calibrate by running the pump at a known speed, collecting the dispensed solution for a measured time, and calculating mL/min. Adjust incrementally while monitoring turbidity, floc formation, and downstream membrane fouling indicators. Re‑check dosing after any change in feed water quality.

What regular maintenance is required to keep the automatic PAM dosing system reliable?

Routine maintenance includes daily visual checks of solution levels, agitation, and pump operation; weekly inspection of suction lines, strainers and filters for blockages; monthly cleaning of the mixing tank and lines to remove settled polymer; periodic replacement of wear parts (pump heads, diaphragms, check valves and seals) per manufacturer schedule; and quarterly calibration of dosing pumps and flow controllers. Keep a record of polymer batch changes, concentrations and system settings. Flush lines with clean water when the system will be idle for extended periods to prevent hardening of polymer in lines.

What common problems should I watch for and how can I troubleshoot them?

Common issues: inconsistent dosing (air leaks, clogged suction tubing or worn pump components), polymer lumps (improper mixing or adding dry polymer too quickly), foaming (excessive shear or overdosing), poor flocculation (wrong polymer type, degraded polymer, or incorrect dose), and hardened polymer in lines (long idle periods or high concentration). Troubleshooting steps: check suction and discharge tubing for air or blockages, inspect and replace pump seals or check valves, verify polymer concentration and age, run jar tests to confirm dose, purge and clean lines, and reduce pump speed or change to a gentler mixer if shear is an issue.

What does the 1‑year warranty cover and what is excluded?

The standard 1‑year warranty typically covers defects in materials and workmanship under normal use for one year from the date of delivery. It usually includes repair or replacement of faulty components determined to be manufacturing defects. Exclusions commonly include consumable and wear items (pump heads, diaphragms, seals, hoses, filters), damage from chemical corrosion, misuse, improper installation, unauthorized repairs or modifications, shipping damage, and damage from incorrect polymer handling (e.g., hardened polymer, contamination). For warranty service you should keep proof of purchase/serial number, follow specified installation and operating procedures, and contact the supplier or authorized service center for instructions before returning equipment.
