Effectiveness of Polyacrylamide in Reducing Runoff
The use of anionic polyacrylamide (PAM) as a soil conditioner could help prevent soil loss by water. In this study, we determined the effective granular PAM rate that best reduces runoff and soil loss from Oxisols. Furthermore, the effectiveness of the selected PAM rate was tested by applying it in a mixture with gypsum (G) or lime (L).
A field experiment was conducted in the spring of 2002 to determine the effectiveness of Polyacrylamide (PAM) in reducing soil erosion from quarter−drains in fields planted to sugarcane. Eroded quarter−drain depth and soil loss per meter were measured after six rainfall events that occurred between 28 March and 1 July and produced a total cumulative rainfall of 368 mm.

The use of anionic polyacrylamide (PAM) as a soil conditioner could help prevent soil loss by water.
Using Polyacrylamide (PAM) to Reduce Erosion
PAM also may reduce the turbidity of the runoff water beyond the reductions provided by the ground cover. In either case, the steeper the slope, the less benefit PAM will provide and the more critical it is that a good ground cover be used prevent erosion.
Abstract: Polymers as a soil amendment is one of the effective measurements to reduce soil erosion. In this study, two polymers, polyacrylamide (PAM) and polysaccharide (Jag C 162), were applied to erosion plots filled with loess soil (tilted at 20 ). For each polymer, four concentration levels—0, 10,
Polyacrylamide: A Review of the Use, Effectiveness,
of PAM is its versatility. Polyacrylamide can be used in furrow irrigation where it reduces erosion and runoff while improving soil and water quality and water-use efficiency. In rain-fed agriculture and sprinkler irrigation, PAM is used to reduce surface sealing and crusting as well as erosion. Polyacrylamide is also used

- What is polyaluminium chloride?
- Polyaluminium Chloride (PAC) is an inorganic polymer coagulant. It is a yellow solid powder that is widely used in water treatments. PAC is better than other aluminum salts such as aluminium chloride, aluminium sulphate, and other various forms of Polyaluminium chlorisulfate and Polyaluminium chloride that they have lower charge than PAC.
- Why is polyaluminium chloride used in water treatment?
- This is the rationale behind the treatment of sewage, industrial water treatment and purification of wastewater. Polyaluminium Chloride is also used in beverage and water bottling firms to eliminate impurities in water. Natural water has several minerals that it collects in the course of flowing.
- What coagulants are used in drinking water purification?
- Currently in Europe, 44 000 million m3/year of drinking water are produced. For its purification, inorganic polyaluminium coagulants (PAC), polyaluminium chloride (PACl), in concentrations of 20-30 mg/L, are used in drinking water treatment plants.
- What is polyaluminium chloride production?
- PolyAluminium Chloride production is one of the most exigent process for glass-lined equipement due to its high corrosive and abrasive effect. That's why, the experience and the qualification of De Dietrich Process Systems allow to meet qualitatively those process requirements.
