Treatment of desizing wastewater by catalytic thermal treatment and coagulation

Performance of metal compound on thermolysis and electrolysis on sugar industries waste water treatment: COD and color removal with sludge analysis (batch-experiment)

“…The thermochemical precipitation (or thermolysis) undergoes complex reactions over the reaction time, thereby affecting the pH of the reactor mass. The compounds probably undergo hydrolysis to a limited extent with the formation of small amounts of lower carboxylic acids (Kumar et al 2009). The effect of initial pH on electrolysis was carried out at pH 2-10, 20 mm electrode distance and 2 A current.…”

Value-added utilization of oil palm ash: A superior recycling of the industrial agricultural waste

“…A developing research by the invention of a wide range of treatment technologies (precipitation, coagulation-flocculation, sedimentation, flotation, filtration, membrane processes, electrochemical techniques, biological process, chemical reactions, adsorption and ion exchange) with varying levels of success has accelerated a dramatic progress in the scientific community [13][14][15][16][17][18][19]. Of major interest, adsorption process, a surface phenomenon by which a multi-components fluid (gas or liquid) mixture is attracted to the surface of a solid adsorbent and form attachments via physical or chemical bonds, is recognized as the most efficient and promising fundamental approach in the wastewater treatment processes [20].…”

Feasibility Study of Individual Treatments of Desizing Wastewater

“…There also has some methods about pretreatment to remove COD and PVA of desizing wastewater at home and abroad, such as Fenton oxidation method, catalytic thermal treatment process [10], hybrid anaerobic baffled reactor (HABR) [11]. However, there is no study about individual treatment of desizing wastewater is the most refractory of all processes which has the character of less quantity, high-concentration organic contaminants, low BOD/COD value.…”
