FAQ

What is the Automatic PAC Dosing unit used for in desalination plants?

The unit automatically meters and injects powdered activated carbon (PAC) slurry into pretreatment or feedwater lines of desalination and reverse osmosis (RO) systems. Typical uses include removal of dissolved organic matter, micropollutants, algae metabolites, taste and odor compounds, and reducing fouling and formation of disinfection by-products before membranes.

What does the "500 L/h" rating mean and how does it affect my application?

The 500 L/h rating refers to the maximum slurry delivery or handling capacity of the dosing system (up to 500 liters per hour of prepared PAC slurry or slurry feed throughput). It determines the maximum dosing throughput and is suitable for small-to-medium pretreatment trains. Select the unit when your required PAC slurry flow and dosing duty fall at or below this capacity.

How is the PAC dosing unit typically integrated into an RO/desalination pretreatment train?

It is installed upstream of sand filters, ultrafiltration, or cartridge filters so PAC adsorbs organic foulants and micropollutants before membranes. The unit is connected to a PAC hopper or feeder, slurry-mixing tank, feed pump and injection point (gravity or pressurized line). Integration commonly includes PLC or analog control signals for flow-proportional dosing, turbidity/DOC feedback, and interlocks with upstream equipment.

What operational considerations and routine maintenance should I follow?

Use PAC grades recommended for water treatment and prepare slurries within the recommended solids concentration to avoid clogging. Maintain continuous agitation in slurry tanks, inspect and clean feed lines, strainers and metering pumps weekly, and check calibration of dosing pumps periodically. Replace wear parts (seals, diaphragms, valves) as needed. Follow the product manual for flushing, winterization and safe handling of PAC dust.

Which PAC types and dosing ranges are supported?

The system supports commonly used powdered activated carbons formulated for water treatment. Dosing range depends on slurry concentration and pump settings — the system can support low to moderate dosing rates suitable for pretreatment dosing scenarios when configured correctly. Consult the technical manual or vendor for recommended PAC particle sizes, slurry concentrations and expected mass dosing rates for your feedwater conditions.

What does the 1-year warranty cover and what are the exclusions?

The 1-year warranty typically covers manufacturing defects in materials and workmanship and functional failures under normal use for one year from delivery. Exclusions commonly include normal wear and consumables (e.g., pump heads, seals, dosing/nozzle tips), damage from improper installation, misuse, chemical corrosion beyond specification, modification, and lack of routine maintenance. To claim warranty, keep proof of purchase, register the product if required, and follow the supplier’s warranty claim procedure.
