Liquid Polymer Dosing Station

polymer preparation unit description

The polymer preparation units are used to automatically prepare polymer solutions.
Polymers are used as coagulants for the suspended particles in the effluents treated in the waste water treatment plants.

Polymer addition is used in the treatment of water both in the primary clarification-flocculation phase and in the last sludge dehydration phase.

In this fully automated system, a metered polymer lotion is made from polymer powder.

Polymer preparation unit principle

The automatic dosing machine is widely used in the waste water treatment, it can mix the compounds continuously and effectively, so the reactive polymer solution appears. These main components of the machine: Polymer feed machine (including material hopper), Dry powder infiltration device, Tank, Level controller, Mixer, Dosage water inlet pipe, Electric control panel

1. Polymer dosing device 

Polymer dosing device is composed of hopper, push screw, electric heater and etc. The effective volume of the hopper can meet the dosage for a long time which is equipped with sight glasses for observing material level monitored by the dry powder level meter. The push screw driven by the high-precision reducer can satisfy the dosage. The electric heater can be installed in the discharge pipe of push screw, and it can prevent the powder from caking.

2. Polymer dissolving device

Polymer dissolving device is composed of pre-soaking device, tank, and 3 sets of mixers. The pre-soaking device is to infiltrate and mix the polymer powder in advance. The 3 tanks are precast mixing tank, homogeneous slaking tank and solution storage tank, in which there is a mixer correspond to guarantee the homogeneity.

3. Water supply device

Water supply device is composed of pipeline, manual ball valve, filter, pressure gauge, solenoid valve, stop valve, and the rotor flow meter, etc.

Polymer preparation unit model

Polymer preparation unit advantage

It is an all-in-one polymer preparation system for the batching of liquid and powder flocculants in a broad range of water-treatment applications in industries such as wastewater, paper, chemical, petrochemical and mineral processing.

This triple-chamber continuous-flow system is available in six models to suit every application, with control panels, powder feeder, diaphragm dosing pumps, mixers and stirrers all integrated into a single solution.

Designed for heavy-duty water-treatment environments, PolyCendos’ dissolving, maturing and storage chambers are constructed entirely in polypropylene with batching screws in stainless steel for outstanding corrosion resistance.

Intuitive control allows users to easily calibrate the powder metering unit and liquid concentrate pump, with batching adjustment managed via a precise speed regulator. Meanwhile, conductivity level probes alert operators to high, low and critically-low levels via emergency warning light.

Polymer preparation unit feature

Continuously working with 3-tank integration design (mixing tank, aging tank, storage tank), easy to operate and maintain, low total cost.

Can be extended as a more automatic 2 storage tank type in accordance with the actual needs.

With powdered or liquid state (optional) dual feed design to meet different needs. 

Proportional allocation function makes it possible to prepare liquid concentration by requirements.

With uniform and moderate concentration to reduce the agglomeration causing by the improper manual allocation. 

Blocking of pipe or pump, unnecessary maintenance costs and powder expenses could be well avoided.

Powder feeding hopper with anti-condensation, heating and insulation function can avoid the agglomeration or deterioration.

When powder feeding hopper reaches the minimum stock, led light warning and automatic stop function makes overall maneuverability more perfect.

Polymer preparation unit application

Water treatment: flocculation of industrial and drinking water

Wastewater treatment: physicochemical treatment

Sludge treatment: centrifuges, screw presses, filter presses to improve dewatering

Mining: concentrate sludge will sink to the bottom faster Speeds up production

Paper industry: retention aid

Cooling water treatment: inhibitors and biocides
