Position: This new powder batching system offers significant benefits over continuous flow systems for flocculants that are slow to dissolve, or need to be aged for a precise time before use.
ProMinent Fluid Controls, has a new range of compact "double decker" Ultromat polyelectrolyte powder batching systems used for the removal of colloidal solids from liquids.
Three variants are available.
The AFD series is for use with powder polymers only, the ATD series for use with liquid polymers only while the ATFD series can handle both liquid and powder polymers.
Each range features separate powder batching/aging and dosing tanks.
The new powder batching system offers significant benefits over continuous flow systems for flocculants that are slow to dissolve, or need to be aged for a precise time before use.
A batch can be prepared in the aging tank while the contents of the dosing tank are being used, then the prepared batch transferred to the dosing tank.
Capable of producing 0.05 to 0.5% flocculant dosing solutions, each of the ranges is available in three sises, with batch quantities of 400, 1000 and 2000 litre/h.
The batching systems are fully automatic, turnkey units supplied complete with two polyethylene or polypropylene tanks, a dry feeder containing a feeder screw pipe heater and powder shortage sensor, and a flow meter for incoming water.
A flushing powder batching system rinses and wets the powder in the ATD and ATFD versions, with automatic batching control of the dilution water.
The AFD and ATFD versions feature pipework for metering of liquid concentrate.
A slow running electronic mixer ensures the aging process is optimised in the upper tank.
A huge range of accessories is available for these units.
This includes storage tanks, aerators and level sensors.
Powder Batching Equipment for pneumatic feed of powder straight from the supply container, such as Big-Bag is also available.
ProMinent also offers redilution units, flushing unit, metering gauges and pumps for the concentrate and the prepared solution.
