Anionic PAM: It is widely used in waste water treatment of chemical industry, municipal sewage treatment, such as coal washing, mineral processing, metallurgy, iron and steel industry and electronic industry. It is also used in oil industry to enhance oil recovery which is widely used.
Polyacrylamide for wastewater treatment. ... a maximum of 12.5% of waste water bottle is recycled at different recycling plants. ... The combination of alum and anionic polyacrylamide gave 91.12% ...
A major use of organic polymers in water treatment is as a coagulant aid to bridge the coagulated particles formed when an aluminium or iron salt has been used as the primary coagulant. An appropriate polyelectrolyte can increase floc size; a strong dense floc of regular shape is preferred. The large aggregates that form then settle more rapidly.
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.
Flocculants ( Polyelectrolyte ) - Chemicals Polyelectrolytes are water-soluble polymers carrying ionic charge along the polymer chain. Depending upon the charge, these polymers are anionic or cationic.
In industrialized countries, PAM is an integral part of public health sanitary strategies and water management due to its importance in the function of municipal and industrial waste water treatment plants. Without utilizing PAMs, the limits prescribed by the EU water framework directive (DIRECTIVE 2000/60/EC of 23 Oct, 2000) cannot be achieved.
PAM polyacrylamide and its application in water treatment 2015-05-16 07:10:57 Environmental protection is the material foundation, and protection of water resources, water pollution control and governance is an important part of environmental protection.
[For Effluent Treatment Plants] - Anionic polyelectrolyte . RUB FLOCK 100 is a high molecular weight flocculant of polyacrylamide type. It is used as clarification and filtration agent of river water, waste water and industrial water. It has wide application in process treatment of mining, metal & ceramics.
In general, cationic polyacrylamide for the treatment of organic sludge, anionic polyacrylamide for the treatment of inorganic sludge, alkaline is very easy to use cationic polyacrylamide, and acidity should not use anionic polyacrylamide, when the solid content of mud is high, the amount of polyacrylamide is usually large.
The polyacrylamide is dissolved into 0.3% concentration, cross-linking agent is added, and the product can be sprayed on desert to prevent and solidify sand. 8. Chemical mudding agent: Polyacrylamide can be used as chemical mudding agent for plugging water of dikes, ground foundation, channels and the like. 9.
