wastewater treatment polyacrylamide to water treatment coagulants,to calculate the dose of a coagulant or other chemical in mg/l, you will need to know its % w/w strength and specific gravity. the formula is: mg/l 10,000 x % w/w x sg. for example, consider alum at 49 % w/w strength aluminium sulphate (as al2(so4)3.18h2o) and with a sg of 1.29.
chemical polyacrylamide (PAM) flocculant types
anionic polyacrylamide (apam): apam is a water-soluble high-molecular-weight polymer used extensively for coagulation and sedimentation in various industrial wastewater treatments, such as steel plant effluents, electroplating wastewater, metallurgical wastewater, and coal washing wastewater. it is also used for drinking water clarification low cost
controlled polymerization of acrylamide via one-pot and one,copper-catalyzed controlled polymerization of acrylamide has always been a challenge, which typically exhibits low monomer conversion and broad molecular weight distribution (mwd) or requires complex/multistep reaction procedures, due to the highly active nature of the am radical and its side reactions. to overcome the above challenges, herein, we report the successful synthesis of well
polyacrylamide polymer as soil conditioner china
product description polyacrylamide is, simply called pam, a water-soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile, chemical and environment protection fields.
super white polyacrylamide high purity pam,polyacrylamide (abbreviated as pam or paam) is a polymer with the formula (-ch2chconh2-). it has a linear-chain structure. pam is highly water-absorbent, forming a soft gel when hydrated. in 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.[1]
water soluble polymer flocculants synthesis
alagha et al. investigated the adsorption characteristics of polyacrylamide (pam)-based polymers on anisotropic basal planes of kaolinite using qcm-d. 182 they first deposited the kaolinite nanoparticles on qcm-d sensor and flowed 500 ppm of al(oh) 3pam flocculant over the sensor at a flow rate of 0.15 ml min −1.
