A physicochemical treatment (coagulation–flocculation) was applied to a slaughterhouse wastewater, using anionic polyacrylamide as coagulant aid to improve the settling velocity of the flocs formed with the coagulants used: ferric sulphate, aluminium sulphate and polyaluminium chloride.
Anionic Flocculants For Mining Process SINOFLOC anionic polyacrylamide flocculants is suitable for using as a settlement and centrifugation aid in many different mineral processing applications and is particularly effective under very low PH conditions, as encountered in acidic leach operations.
WELLDONE specializes in manufacturing GREEN CHEMICAL polyacrylamide to industries of wasted water treatment, oil drilling muds and fluids additives, we have been in this area for more than 20 years
Once the pH was selected and with the same coagulant dose, the dose of polyelectrolyte used as coagulant aid was varied between 0 and 100 mg l-1. When anionic polyelectrolytes are used as coagulant aids in conjunction with metal salts, they are usually added after the coagulant due to the negative charge of the particles in the wastewaters,
The inorganic salt coagulant could reduce turbidity of supernatant, but it play a limited role in improving settling rate, it was found that FeCl3 is the best coagulation agent, PAM is effective flocculant for the sample, and the coagulation effect of cationic flocculation (molecular weight is six million) is better than that of anionic and ...
Quality Polyacrylamide Pam manufacturers & exporter - buy Anionic / Cationic Polyacrylamide Water Treatment PHPA High Viscosity Cationic PAM from China manufacturer.
When processing brown coal, or coal with high clay content, it is sometimes necessary to use a coagulant prior to the addition of a flocculant for settlement applications so as to achieve efficient solids capture and an acceptable overflow clarity. 2. Quality index--- anionic and nonionic polyacrylamide. Appearance. Solid content(%) Hydrolysis ...
Nonionic Polyacrylamide could be used in sand prevention and sand fixation through spraying on desert with dissolving nonionic polyacrylamide concentration and crosslinking agent. This product could also be used as soil moisturizer and the basic raw materials for various modified polyacrylamide. Why is Polyacrylamide Used as Flocculants?
The coal floats and the waste sinks with the subsequent coal again sized and separated into the finished product. Product Details Packaging&Delivery Make an Inquiry anionic polyacrylamide (flocculant)used for coal washing
Polyacrylamide for wastewater treatment. ... the Jar test were used to determine the efficiency of the coagulant. The results showed that cross-linked polyacrylamide worked better than a linear ...
