Metering Systems for Polymers
The elimination of solids from liquids requires the use of liquid or powder polymers. This is achieved with polymer preparation and metering systems. The experts in wastewater treatment at ProMinent understand how to provide the efficient technology to implement this specialist application. For the most stringent requirements, they developed DULCODOS and ULTROMAT metering systems, which are especially easy to assemble and operate.
Products
Metering System ULTROMAT ULFa
Extraction rates of up to 8,000 l/h
Polymer preparation station ULTROMAT ULFa (continuous flow system): This metering system can be used to batch flocculation aids for the preparation of a ready-to-use polymer solution. The system was designed for the fully automatic batching of polymer solutions. more
Your benefits
- Processing of powdered polymers (0.05 – 0.5 %) and liquid polymers (0.05 – 1.0 %)
- Minimal carry-over of product and thus high-quality results
- Operator-controlled input of solvent concentration and calibration of powder feeder unit and liquid concentrate pump
- Gentle mixing of the polymer solution using electric stirrers, running as standard at approx. 700/840 rpm, available as an option with gearbox stirrer in the first preparation chamber running at approx. 70/84 rpm (relative to 50/60 Hz mains supplies)
- New: information about consumption of the liquid polymer via 4-20 mA signal of liquid concentrate pump DFXa
- Pressure sensor for measuring the liquid level
Metering System PolyRex
Capacity range of up to 8200 l/h
The metering system PolyRex is a double-decker batching station for the processing of liquid and powdered polymers. It consists of the feed and mixer unit and the two stainless steel double-decker tanks. The polymers used are ideally utilised. more
Your benefits
Compact controller ABB AC500 PM573-ETH and touch panel CP635
- Dust-free filling of the powder storage tank thanks to use of a vacuum conveyor
- Double screw metering unit with 2 counter-rotating conveyor screws enables low-pulsation metering with a high level of dosing precision.
- Pressure reducer for a constant water supply
- Effective 3-phase mixing of the polymer solution
- No short-circuiting effect: polymer particles cannot pass through the process without activation
Metering system POLYMORE
Capacity range of up to 18,000 l/h
The metering system POLYMORE is an inline batching station in which the liquid polymer is introduced into the pressure-encapsulated multi-zone mixing equipment with the dilution water through a peristaltic pump. The result is a prepared and homogeneous polymer solution. more
Your benefits
- Wall-mounted: saves space
- Low-maintenance peristaltic pump for metering the liquid polymer
- Simple and fast to connect: requires only water, liquid polymer and power
- Automatic control
