Comparison of naturally prepared coagulants for removal
The wastewater generated by the textile industry is rated as the most polluting among all industrial sectors considering both volumes discharged and effluent composition. Present investigation intended for COD and color removal from textile wastewater using naturally prepared coagulants i.e. Surjana Seed Powder (SSP), Maize Seed Powder (MSP) and Chitosan.
The characterization of the post-treatment product using GC–MS studies revealed intermediate compounds. Cost analysis was also performed for the treatment process. Further, the obtained optimum conditions were applied to the treatment of six samples of real textile effluent. Electrocoagulation was satisfactory in only four of the cases.
Removal of Color from Different Dye Wastewater by Using
waste water [24, 35]. The sources of industrial wastewater are like cement industries, pharmaceutical industries, food industries, textile industries, pulp paper industries, rubber industries, color photography Leather industries, cosmetics industries, plastic industries, organic compost and other industries [9, 35].
Color removal from waters with low turbidity requires considering specific unit in water treatment plant (Nalco, 1988). Color removal by chemical oxidation, especially when chlorine is used as oxidative agent, produces problematic products (AWWA, 1999; Kawamura, 2000; Rezaee et al., 2008). Application of advanced oxidation process using TiO 2
Textile Wastewater Treatment: A Critical Review
methods implemented for the treatment of the dyes in textile wastewater. This review also explains the critical study of the most generally used methods (chemical, physical and biological) of dye removal from textile industrial effluents. II.TEXTILE OPERATIONS . Textile Printing and dyeing processes include pretreatment,
The main environmental impacts of the textile chain derive from the so called wet processes , mainly implemented by the textile finishing industry. Water is used as the principal medium to apply

- What are anionic Polyacrylamide flocculants used for?
- Today there are several anionic polyacrylamide flocculants -based products marketed for use in construction site sediment management. These products can be applied for erosion control, clarification of sediment laden runoff, and de-mucking of wet sediment during pond cleanouts.
- How is an anionic polyacrylamide flocculant synthesized?
- In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
- Is polyacrylamide a cationic or nonionic polymer?
- rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer CO-CHEMICAL PROPERTIESPolyacrylamide polymers can exist in cationic, anionic or non-ionic forms, depending on their ionic charge. The non-ionic form of polyacrylamide is generated from the basic polyme
- What is anionic polyacrylamide?
- technology-oriented and customer first. Anionic Polyacrylamide is produced when acrylamide is polymerized with an anionic comonomer. Water soluble Polyacrylamide have been used for decades to facilitate solidliquid separations in wastewater and drinking water treatment, the pulp and paper industry, aquaculture, and many other industrial processes.
