Product Description

Decription of Cationic PAM

Cationic polyacrylamide (CPAM) is a linear polymeric compound, because it has a variety of lively groups, affinity, adsorption and many substances forming hydrogen bonds. Mainly flocculation of negatively charged colloidal, turbidity, bleaching, adsorption, glue and other functions, for dyeing, paper, food, construction, metallurgy, mineral processing, coal, oil, and aquatic product processing and fermentation industries of organic colloids with higher levels of wastewater treatment, especially for urban sewage, sewage sludge, paper mill sludge and industrial sludge dewatering process.

Cationic polyacrylamide (CPAM) specification

Cationic polyacrylamide (CPAM) product features

1, water soluble, and can also dissolve completely in cold water.

2, add a small amount of anionic polyacrylamide products, you can receive a lot of flocculation effect. Just add 0.*1~*0ppm (0.*1~*0G/m3), to fully play its role.

3, while using the products and inorganic anion polyacrylamide flocculant (polymerized ferric sulfate, polyaluminum chloride, iron salts, etc), you can display a greater effect.

Function

Cationic polyacrylamide, because it has:

1 purifying, clarifying roles;

2, subsidence promoter action;

3, filtration promoter action;

4, thickening effect and its effects.

In wastewater treatment, sludge dewatering, dressing, washing, papermaking and so on, can fully meet the various requirements in the field

Using methods and points for attention:

*0% ion of cationic polyacrylamide

1, through a small test, determine the best model and optimum dosage of the product.

2, product preparation to 0. 1% (solids) concentration of water solutions, to neutral water without salt.

3, when dissolved in water, this product is evenly sprinkle into the mix in the water, proper heating (< *0 °C) can speed up solution.

4, the product is hygroscopic, should be seals stored in a cool dry place, temperatures below *5 ° c.

5 avoid sub, solid product on the floor to prevent moisture absorption after slide.

Package and storage

This product is non-toxic, moisture, rain, avoid sun exposure.

Storage period: 2 years, *5kg paper bag (lined with plastic bags to stick the plastic paper bags outside).

Application in wastewater treatment

Cationic polyacrylamide in wastewater treatment applications

1. Often use powdered organic wastewater of cationic polyacrylamide: 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 polyacrylamide, poly-aluminium chloride and anionic polyacrylamide 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 polyacrylamide can include water resistance ****0%

Cationic polyacrylamide using processes

Polyacrylamide used to follow the following principles:

1, granular polyacrylamide 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 *0 ° 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.

PAM 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.
