Flocculant polyacrylamide for domestic sewage purifying
Polyacrylamide is used for the treatment of domestic sewage and organic wastewater. Polyacrylamide is positively polarized in a compatible or alkaline medium. In this way, polyacrylamide flocculates and precipitates sewage with negatively charged particles in the wastewater, which is effective for clarification . Such as alcohol wastewater, papermaking wastewater, urban wastewater treatment plant wastewater, beer wastewater, monosodium glutamate wastewater, sugar wastewater, high organic wastewater, feed wastewater, textile printing and dyeing wastewater, etc., the use of cationic polyacrylamide is more than anionic, non-ionic The effects of polyacrylamide or inorganic salts are several or ten times higher, because this type of wastewater is generally negatively charged.
Oil field additive polyacrylamide, which has two types: emulsion and solid. It is a multifunctional additive. It is used in the oilfield drilling process to enhance the mud, stabilizer and sedimentation flocculation to improve the rheology of the mud. Improve the size of suspended particles, increase the suspension force, and accelerate the filtration and separation of crude oil. As a soil structure forming agent, it can improve the impact resistance of the surface of the well wall, and make the liquid slurry that is not easy to disperse to obtain an efficient separation effect when drilling through the layer. Partially hydrolyzed homopolyacrylamide reacts with methylolation of formaldehyde, glyoxal, etc. to produce products containing methyl groups in side chains, which can obtain satisfactory results in crude oil production.
