Cationic Polyelectrolyte
In China

1. Often use powdered organic wastewater of cationic polyelectrolyte: is usually suspended in wastewater sewage flocculation and sedimentation of particles with a negative charge. Based on cationic flocculation unit in acidic or alkaline media, relying on the positive electricity is extremely effective for rapid clarification of sewage. In addition to powdery polyelectrolyte, poly-aluminium chloride and anionic polyelectrolyte is being increasingly broad application in organic wastewater. 

2. Alcohol factory wastewater, beer factory wastewater, MSG factory wastewater, sugar factory wastewater, meat products factory wastewater, beverage factory wastewater, textile dyeing factory and various sewage factory of engineering processing of wastewater in the, contains various organic solvent, and inorganic and the organic sulfide, and hydrocarbon class, and chlorine, and oil, and mercury and he on environment harmful of components, can with polypropylene n amine for flocculation coagulation yihou then emissions. Can also be used as slurry treatment agent in oilfield development process, selective plugging agent, thickening agent injection, textile printing and dyeing process of softening agent, Antistatic agent and common sterilization, disinfectants, etc. 

3. Used for water purification, water/oil emulsion, oil-containing wastewater treatment, recycling of waste water and sludge dewatering; Pam can effectively reduce the friction of the fluid, trace polyelectrolyte can include water resistance 50-80% 

Cationic polyelectrolyte using processes: 
1, granular polyelectrolyte flocculant agent cannot directly in addition to sewage. It must first be dissolved in water before use, using its aqueous solution to wastewater treatment.

2 water should be clean, dissolving granular polymer (such as water), and cannot be a sewage. Water at room temperature, typically do not require heating. Water temperatures below 5 ° c are dissolved very slowly. Dissolved water temperature increase faster, but more than 40 ° c causes the accelerated degradation of polymers, effect using the effect. Tap water is suitable for the preparation of polymer solution in General. Strong acid, alkali, salt-laden water is not fit for the preparation. 

3, selection of polymer solution concentration, company recommends to 0.1% per cent, that is, 1 liter of water and 1g-3G in polymer powder. Polyelectrolyte concentration options to take into account the following factors: Preparation tank is small and large amount of medication every day, proposed grading of slightly dense (such as 0.3%). Polymer molecular weight is high, slightly dilute some of the proposed distribution (such as 0.1%). In polymer solutions into the sewage, such as dispersed when the situation is not very good for equipment reasons, recommends slightly dilute some of the distribution. In short, polymer concentration too large will cause agitator motor load is too large, can also cause after entering the water dispersing condition is not good, affect the results. Worthy of dilute some help to increase the effect. 

4.Centrifugal pumps for distribution with a solution do not transfer, so as to avoid high speed rotating blades caused shear of polymer degradation. Preparation of specific methods are as follows: Solution (such as lab beakers, preparation of plant pot) by adding a certain amount of water, water volume and concentration calculate the required amount of powdered polymers, polymer.
