Water & Waste Water

Treatment

Water & Waste Water

Treatment

Three polymer types

• Solid grade – powder and bead

• Liquid grade – inverse emulsion and LDP

(Dewatered emulsion)

• Liquid grade - solutions

Water & Waste Water

Treatment

Powder Systems

• Storage options in line with delivery packages – 25kg

sack, 700 - 900kg big bag, 25 tonne road tanker

• Correct storage of material to ensure product is fit for

purpose (damp, cold atmosphere, etc.)

• Ensuring Health & Safety issues are eliminated

• Correct dissolution and mixing times

• Sizing of equipment

Dosing

• Why in line dilution is required

Water & Waste Water

Treatment

Effective dosing for specific process

• Dosing strength variation to optimize floc formation for

different dewatering processes i.e. centrifuges, belt

presses, etc.

VENTURI EDUCTOR

Water & Waste Water

Cold ambient air

drawn in by

venturi

Cone & venturi restrictions

create high pressure in the

air line generating heat, but

also reducing conveying

efficiency

Venturi draws ambient

air and powder into

conveying line

Motive energy created

by blower shared with

additional ambient air,

impacting on conveying
