Treatment Chemicals for Particulate Removal from Construction

Treatment chemical application can be directly onto soil through the mixing in of dry granular powder or in liquid spray form. Liquid application is more effective for chemicals that require uniform application at low concentrations, such as PAM. Using liquid treatment chemicals in a hydroseeding mix can bind the seed, fertilizer and other

Recent Achievements in Polymer Bio-Based Flocculants for

Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)¡ªa non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [8,9,10]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.

chemical treatment to reduce turbidity in pumped construction

Chemical Treatment to Reduce Turbidity in Pumped Construction

Results from laboratory jar tests using two coastal plain sediments of North Carolina suggested that a cationic PAM was the most effective in reducing turbidity, followed by a nonionic PAM. Anionic PAM was effective in whole-soil jar tests but not when turbid supernatant was tested.

Three types of polyacrylamide (PAM) flocculants with different charges (cationic PAM WD4960, nonionic PAM M351, and anionic PAM WDA110) were used for water treatment residuals (WTRs) conditioning, and the physicochemical, morphological and structural characteristics of raw and conditioned WTRs were investigated. Rheological methods were

PAM refers to a group of water-soluble molecules formed by polymerization of AMD monomers. PAMs have been used for decades in a variety of industries and have proven particularly effective in facilitating the solid¨Cliquid separation for waste and drinking water treatment as well as for the clarification of various types of effluents.

The Thermal Gelation Behavior and Performance Evaluation

It is well known that the gelling solution prepared with high molecular weight PAM possesses high initial viscosity. This would make it difficult on the injection process for water shutoff treatment. Fortunately, gel systems prepared with nonionic polyacrylamide (NPAM) were studied.

treatment of beneficiation wastewater from flotation of Kyanite with oleate, the turbidity of wastewater was high, and the pH of backwater should be controlled at about 7.5. Aluminum sulfate combined with nonionic PAM can be used to treat the backwater to greatly reduce the turbidity, and iron salt was not suitable as a coagulant[7-8]. 3.1.4.
