Technological Solutions for Erosion Control and Water
Development of new polyacrylamide (PAM) blends and delivery methodologies has resulted in a whole new class of in-situ erosion control and water clarification tools. Multi-disciplinary environmental industry projects for mining, construction, water treatment and biological research have proven this class of Best Management Practices (BMPs).
Select Water Treatment Additives Discharge Application
Select Water Treatment Additives (WTAs) are those commonly used chemical products that are added as conditioners to improve the water quality for use in a system or process, condition and treat the water to make it suitable for discharge, are considered to not adversely affect aquatic life, are a single chemical (i.e., not a mixture of chemicals), and can be regulated through a facility’s National Pollutant Discharge Elimination System (NPDES) permit with a chemical specific water quality ...
Reducing the Water Quality Impacts of Urbanizing Landscapes
Overall, this work reaffirmed the need to carefully screen a number of flocculants for the soil on a construction site to obtain the best performance in reducing turbidity in runoff discharges. Objective 2. Straw is one of the most common mulches to protect grass seed and prevent erosion as the grass becomes established.
Improving Sediment and Erosion Control Measures - NORTH
Erosion Control Mechanically bonded fiber matrix (MBFM) is usually much more effective than straw; wood fiber is not always better. Spraying dissolved PAM on the soil or in the hydroseeding mixture is not always beneficial in reducing erosion, but the turbidity of the runoff is usually reduced for the first storm.
Comparative Costs Of Erosion And Sediment Control
In erosion control work it has the following uses: (1) j^emporary Soil Stabilization - On denuded areas it penetrates the soil and binds soil particles into a coherent mass that reduces erosion by water. (2) Chemical Mulch - On seeded areas it penetrates the soil and binds soil particles into a coherent mass.
Stormwater - NYS Dept. of Environmental Conservation
Stormwater runoff carries pollutants into waterbodies. Stormwater is water from rain or melting snow that doesn't soak into the ground but runs off into waterways. It flows from rooftops, over paved areas and bare soil, and through sloped lawns while picking up a variety of materials on its way.

Organic polyelectrolytes in water treatment - ScienceDirect
All polymers used as flocculants in water treatment, must be water soluble. In aqueous solution polymers very often adopt a random coil configuration, shown schematically in Fig. 1. For very high MW polymers, the size of the coil is typically of the order of a hundred nm, with the size being proportional to the square root of the MW.

Infiltration and erosion in soils treated with dry PAM, of
PAM(M) was, however, more effective than PAM(H) in controlling soil erosion. The lower levels of soil erosion in the PAM(M) treatments were ascribed to its lower viscosity when in solution, which, in turn, enhanced the ability of this solution to more uniformly and efficiently cover and treat the soil surface aggregates.

“Chemical treatment has been used to treat drinking water for 70 to 80 years, and our thought was to try it in construction as well.” Adding flocculant to a sample of water from the Minnesota River causes sediment to clump and sink.
Clearing Muddy Pond Waters | VCE Publications | Virginia Tech
Clearing Muddy Pond Waters. Any area of bare soil provides a source for soil erosion. Livestock trampling shorelands and wading in ponds or upstream waters add large quantities of soil and undesirable manure. Bottom-feeding fish, especially carp and bullheads, can contribute to muddy waters by rooting and stirring up bottom silt in their search for food.
