Water & Waste Water
Treatment
Three polymer types
• Solid grade – powder and bead
• Liquid grade – inverse emulsion and LDP
(Dewatered emulsion)
• Liquid grade - solutions

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.

JETWETBLOWER
AIR HEATED
CONE
FEEDER
VENTURI EDUCTOR
Water & Waste Water
Treatment
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
efficiency
