Polymer preparation & dosing systems in Pakistan

Where this equipment fits

Dewatering, thickening, clarification and DAF.

Textile colour, tannery process streams and food effluent should be characterized separately. For an industrial ETP in Kasur, Sialkot or Faisalabad, review pH, metals, oil and batch variability before selecting chemical treatment. Include the additional chemical sludge in the disposal and dewatering scope.

How to select polymer preparation & dosing systems

Use these inputs to define the equipment duty before comparing proposals.

• 01Polymer form and tested dose
• 02Capacity and ageing time
• 03Dilution water and dosing range

What affects the price in Pakistan?

The quoted price depends on polymer form and tested dose, materials, controls and the agreed supply scope. For a useful comparison, identify freight, taxes, installation, commissioning and initial spares as separate proposal items where applicable.

For replacement equipment, share the existing nameplate, photographs and connection dimensions. For a new installation, share the design flow or loading, site location and available space. Final availability, delivery and performance terms are confirmed with the selected equipment.

Integration with your treatment plant

Representative laboratory analysis and jar-test results. Chemical compatibility, storage and dosing range. Sludge production and downstream biological compatibility. These interfaces should be checked alongside the individual equipment specification.

Reproduce screw thickener conditioning

Use the screw thickener trial and acceptance guide to connect polymer product, active dose, preparation, maturation, dilution and mixing with hydraulic loading, dry-solids loading, screen drainage, thickened sludge and filtrate.

Reproduce gravity belt thickener conditioning

Use the gravity belt thickener trial and acceptance guide to connect polymer product, active dose, preparation, maturation, dilution and mixing with belt loading, drainage, thickened sludge and filtrate.

Reproduce rotary drum thickener conditioning

Use the rotary drum thickener trial and acceptance guide to connect polymer product, active dose, preparation, maturation, dilution and mixing with hydraulic loading, dry-solids loading, screen drainage, thickened sludge and filtrate.

Reproduce centrifuge conditioning

Use the decanter centrifuge trial and acceptance guide to connect polymer product, active dose, preparation, maturation, dilution and injection with dry-solids load, torque, cake, centrate and stable operation. The installed system should reproduce the accepted trial basis.

Polymer preparation for a sludge screw press

If this system will serve mechanical dewatering, review the sludge screw press trial and quotation guide. State the tested polymer basis, preparation and maturation conditions, dosing range and calibration method so the package can reproduce the trial conditions.

Polymer preparation for DAF conditioning

A DAF polymer system should reproduce the tested product, concentration, ageing, dilution and dose range without damaging formed floc. Use the DAF treatability and quotation guide to connect polymer preparation with pH control, coagulant dosing, flocculation, flotation and sludge handling.

Check transfer pumps against the prepared polymer

If a positive-displacement pump is proposed for liquid polymer transfer, use the progressive cavity pump selection guide to define viscosity, chemistry, rotor and stator compatibility, speed range, pressure, dry-run protection and field calibration. Polymer dosing accuracy still depends on the complete preparation, dilution and control system.

Reproduce filter press conditioning during feeding

The filter press feed pump and control guide connects polymer preparation, active dose, calibration and mixing with the complete pressure-dependent feed cycle. The installed system should reproduce the representative trial rather than rely on a fixed chemical setting.

Reproduce belt press conditioning

Use the belt filter press selection and trial guide to connect polymer product, active dose, preparation, maturation, dilution and mixing with hydraulic loading, belt speed, cake and solids capture. The installed system should reproduce the accepted trial condition.
