99% CPAM Wastewater Treatment Flocculants For Wastewater Treatment Of Various Industries
Description Of Cationic Polyacrylamide CPAM:
Cationic polyacrylamide (CPAM) appearance is white powder, is a linear polymer compound, because it has a variety of active groups, and many substances can be affinity, adsorption form hydrogen bonds.Molecular weights range from 8 million to 12 million.Ionic degree from 20% to 55% water solubility, can be dissolved in water in any proportion and insoluble in organic solvents.Effective pH range of 1 to 14, high polymer electrolyte characteristics, suitable for negative charge and rich in organic waste water treatment.
Package: Inner package : Plastic PE film; Outer package: woven bag , N.W 25KG/BAG
Storage: Stored in a dry cool and ventilate place, it will keep good for 2 years.
How is polyacrylamide used as a flocculant?
We all know that polyacrylamide is a common, is also commonly used flocculant, and the effect of flocculation is very good, then polyacrylamide in which industry is used as a flocculant?
Is there any way to add it?
How is polyacrylamide used as a flocculant?
1. Condensation stage: polyacrylamide When we add a liquid (flocculant or polyaluminum chloride), this is a process of injecting the liquid into the solidification tank and rapidly condensing with the raw water to form tiny flowers.
At this point, the water has changed.
It is more opaque and requires water to generate strong turbulence.
In beaker experiments, stirring should be done quickly (250-300 RPM) for 10-30 seconds, usually no more than 2 minutes.
So this is going to be very good.
2. Flocculation stage: This is the process of silk flower growth and thickening. The polyacrylamide needs proper turbulence and sufficient residence time (10-15 minutes).
After r this, a large number of fragrant flowers can be observed slowly sinking and forming a transparent layer.
The beaker was first stirred at 150rpm for about 6 minutes and then stirred at 60rpm for about 4 minutes until it was suspended.
See how it reacts and adjust it if it doesn't work.
3. Settlement stage: treatment of domestic sewage and organic waste water, this product in supporting or alkaline medium with positive charge, polyacrylamide to make sewage suspended in the sewage flocculation precipitation.
This is a flocculating sedimentation process in a sedimentation tank, which requires a slow flow of water.
In order to improve the efficiency of -, usually use the inclined tube (plate) sedimentation tank (optimization, through air flotation separation of flocculation), and a large number of coarse scorpion flower is inclined tube wall is blocked (board) of the upper water is clear, the rest of the small diameter and density of fragrant flowers falling slowly, and continue to collide with each other, the residual turbidity basic remain unchanged.

Appliciation of cationic polyacrylamide
Polyacrylamide products as flocculating agents, mainly used in industrial solid-liquid separation process, including settlement, clarification, concentration and sludge dehydration and other processes, used in the municipal sewage and meat, poultry, food processing wastewater treatment process of sludge precipitation and sludge dehydration,Through the electric neutralization of the positively charged group on the negatively charged organic colloid in the sludge and the excellent bridging and condensing function of the polymer, the colloid particles are promoted to gather into large flocculent, which can be separated from the suspension. The effect is obvious and the dosage is small.
