The effective PH value range to the cationic polyacrylamide is 7 ~ 14, the effect is good in the treatment of the neutral and alkaline water. The effective PH value range to the nonionic polyacrylamide is 1 ~ 8, the effect is good in the treatment of the neutral and acid water. The anionic polyacrylamide can be used for the flocculation and the sedimentation, the sedimentation and the clarification treatment of various industrial waste water, such as the iron and steel plant waste water, the

Challenges and opportunities in the removal of sulphate

Sulphide oxidation is a natural phenomenon, where the causes are identified to transcend the beliefs of oxygen and water being the usual culprits. Additional sulphide oxidizers are identified as hydroxyl ions and CO 2 in different environmental conditions (Evangelou and Zhang, 1995). Sulphide oxidation occurs due to both abiotic and biotic reasons.

Stability of Biopolymer and Partially Hydrolyzed

Abstract There are many oil reservoirs worldwide with substantial amount of H 2 S but otherwise very favorable conditions for polymer flooding such as low temperature, high permeability, and moderate to high oil viscosity. However, there is a legitimate concern about the chemical stability of polymers when there is dissolved oxygen in the injection water or injection facility and its high

Flocculants and Coagulants | ChemTreat, Inc.

Flocculation and coagulation treatment chemicals are used in effluent wastewater water treatment processes for solids removal, water clarification, lime softening, sludge thickening, and solids dewatering. Coagulation treatment neutralizes the negative electrical charge on particles, which destabilizes the forces keeping colloids apart.
