What is praestol?
Description. PRAESTOL anionic and nonionic polymers are high molecu- lar weight, water-soluble flocculating agents made by the co- polymerization of acrylamide with itself or various anionic (negatively charged) monomers.
What is a polymer flocculant?
Polymer flocculants are water-soluble polymers which can form flocs from individual small particles in a suspension by adsorbing on particles and causing destabilization through bridging or charge neutralization. Polymer flocculants promote the separation of particles from water to clean water.
What is mannich polymer?
Mannich: Mannich polymer is a high molecular weight, very viscous solution polymer that was widely used in wastewater treatment plants in 1990s. They consist of polymer gels emulsified in 30% hydrocarbon oil.
What is flocculant for?
Used in a wide range of industries and applications, flocculants help to remove suspended solids from wastewater by aggregating contaminants into flakes or “flocs” that float to the surface of the water or settle at the bottom.
Is polyacrylamide a flocculant?
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
What is Mannich reagent?
The Mannich reaction is an organic reaction which consists of an amino alkylation of an acidic proton placed next to a carbonyl functional group by formaldehyde and a primary or secondary amine or ammonia. In the Mannich reaction, primary or secondary amines or ammonia, are employed for the activation of formaldehyde.
What is Mannich base briefly explain?
A Mannich base is a beta-amino-ketone, which is formed in the reaction of an amine, formaldehyde (or an aldehyde) and a carbon acid. The addition of a carbanion from a CH acidic compound (any enolizable carbonyl compound, amide, carbamate, hydantoin or urea) to the imine gives the Mannich base.
What is flocculant in chemistry?
flocculation, in physical chemistry, separation of solid particles from a liquid to form loose aggregations or soft flakes. These flocculates are easily disrupted, being held together only by a force analogous to the surface tension of a liquid.
What does flocculating agent mean?
Flocculating agents are chemical additives that cause suspended solids to form aggregates called flocs. These agents are used in water treatment, municipal and industrial waste treatment, mineral processing, and papermaking. Flocculants are usually selected by the results of laboratory-scale experiments.
Which is the equivalent of praestol 2500 for potassium chloride?
For Potassium Chloride Producing Equivalent Praestol 2500 Blufloc Nonionic Polyacrylamide Non-ionic polyacrylamide (NPAM) is a water soluble polymer formed from acrylamide (a compound with the molecular formula C3H5NO) subunits special for produce Potassium Chloride with high performance.
Which is the best definition of a polymer?
Webster Dictionary defines polymer as “a naturally occurring or synthetic compound consisting of large molecules made up of a linked series of repeated simple monomers” Industry definition – long-chained, high molecular weight, synthetic, water soluble, organic flocculant carrying a cationic, anionic, or non-ionic charge.
