General description for Polymer dosing machine:

(1)  Three tank in one equipment (precast mixing tank,homogeneous slaking tank and solution storage tank); preparation and dosing continuously; easy operationand maintenance; the lowest cost ofmanpower.

(2)  Pour the polymer and water into the tank at the same time; the flow of input water, dilute water and polymer feeding pump are adjustable;any concentrationof the solution (within a certain range) can be prepared and dosingaccording to the actual requirements.

(3)  The high-precision conveying of the polymer dosing device, the delicatedesign of pre-soaking deviceand the constant temperature heating method can reduce agglomerationphenomenon caused of improper artificial operationor prevent the line from clogging, and can ensure the stable concentrationof the solution.

(4) The unique structure and proper rotating speed of the mixer not only can ensure the homogenization solution, but also can not destroy the polymer molecular chain.

Product Application:

• Municipal water and wastewater treatment plants
• Agricultural/fishery community wastewater treatment plants
• Industrial waste treatment plants
• Food/beverage production plants
• Dairy farming/Meat processing plants
• Chemicals manufacturing plants
• Machinery manufacturing/Metal processing plants
• Laundry wastewater
• Other plants requiring dewatering machine (paper manufacturing, building material manufacturing, oilfield associated water accompanied with crude oil mining, etc.)

Work principle of Polymer dosing machine:

(1)  Feed enough dry polymerinto the hopper, the dry polymer will be transported into the pre-soaking device by polymer dosing device, open the solenoidvalve of water inlet pipe, the dry polymer becomes wet in the pre-soaking device, and then the wet polymer drops into the mixingtank by gravity.

(2)  The pre-mixed solution flows into the homogeneous slaking tank through the overflow weir, then the solution will be stirredand compound again in the homogeneous slaking tank. The solution will reach the state of homogeneous, curing and active after low-speedsoft effective stirring for a certain time. Then the solutionflows into the solution storage tank through the overflow weir,here, the polymer solution has been prepared.

(3)  When the solutionstorage tank is full, the liquidlevel switch gives signals and the polymer is ready, and the indicator for “Ready” is on.

(4)  The polymer feeding pump starts, and the solenoid valve for dilution water opens, the solution with constant concentration will be dilutedto the required concentration accordingto the actual usage, and then the solution can be poured into the required equipment.

(5)  The liquidlevel in the solution storagetank reaches the set low level,the liquid level switch gives signals, this device can repeat the above step 1, 2 and 3 automatically, and ensure that the solution storage tank has plentyof polymer solution.
