flocculants in wastewater treatment polyacrylamide
flocculation is the separation of a solution, commonly the removal of sediment from a fluid. the term is derived from floc, which means flakes of material; and when a solution has been flocculated, the sediment has formed into larger aggregated flakes, making them easier to see and remove. this process occurs naturally, or it can also be forced

application of flocculants in wastewater treatment
abstract. flocculation is an essential phenomenon in industrial wastewater treatment. inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. however, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.
industrial water demand and wastewater- acs publications,bangladesh has experienced massive industrial growth in the past century. with the impressive industrial development, the country struggles to meet the demand for water and manage the wastewater generated. this paper critically analyzes bangladesh’s three significant industrial wastewaters: textile, tannery, and landfill leachate. the textile and leather industries are major freshwater
