praestol 853 BC is a kind of cationic polyacrylamide with slight chagre and high molecular weight mainly used for water treatment.chinafloc C0510 is the equivalent model which can replace of praestol 853 BC totally with good performance.
Cationic polyacrylamide (CPAM) is a linear polymer compound, because it has a variety of active groups, and many substances affinity, adsorption form hydrogen bonds. Mainly flocculating negatively charged colloid, with turbidity removal, decolorization, adsorption, adhesion and other functions, suitable for dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic products processing and fermentation industries organic colloid content is higher wastewater treatment, especially suitable for urban sewage, urban sludge, paper sludge and other industrial sludge dehydration treatment.
1, good water solubility, can also be completely dissolved in cold water.
2, add a small amount of cationic polyacrylamide products, can be greatly flocculated effect. Generally only need to add 0.01~10ppm (0.01~10g/m3), can play a full role.
3, at the same time the use of cationic polyacrylamide products and inorganic flocculants (polyferric sulfate, polyaluminum chloride, ferric salt, etc.).
1. Clarifying and purifying effect;
2. Settlement promotion effect;
3. Filtration promotion effect;
4, thickening and other effects.
Therefore, it can fully meet the requirements of waste liquid treatment, sludge concentration and dehydration, mineral processing, coal washing, paper making and other aspects. Show greater effect.
1, PAM has a unique decolorization ability, mainly used in dye plant high chroma wastewater decolorization treatment, applicable dyes for active, acidic and disperse dyes.
2, can also be used for textile, printing and dyeing, ink and other industrial wastewater treatment.
3. The decolorization rate of wastewater can reach more than 95%, and the removal rate of COD is between 40-70%.
1) For sludge dewatering the corresponding model of this product can be selected according to the properties of sludge, which can effectively dehydrate the sludge before the sludge enters the press filtration. When dewatering, large floc will be produced, non-stick filter cloth will not be dispersed during the press filtration, thick mud cake, high dehydration efficiency, mud cake moisture content below 80%.
2) For the treatment of domestic sewage and organic wastewater, this product in the coordination or alkaline medium are positive, so the sewage suspended particles with negative charge flocculation precipitation, clarification is very effective. Such as the production of food alcohol wastewater, paper waste water, urban sewage treatment plant wastewater, beer wastewater, monosodium glutamate plant wastewater, sugar wastewater, high organic content wastewater, feed wastewater, textile printing and dyeing wastewater, cationic polyacrylamide than anionic, non-ionic polyacrylamide or inorganic salt class effect is several times higher or dozens of times, because this kind of wastewater is generally negative charge.
3) It is used as a flocculant for treating the tap water from river water, with less consumption, good effect and low cost, especially when combined with inorganic flocculant, it will become an efficient flocculant for treating the water works in the Yangtze River, the Yellow River and other basins.
4) Reinforcers and other auxiliaries for paper making. Improve the retention rate of fillers, pigments, paper strength.
5) For oil field economic additives, such as clay swelling agent, oil field acidizing thickener.
6) Used for textile sizing agent, stable grout performance, less pulping, fabric break rate is low, clean cloth surface.
