Q1: What is BWD Water Decoloring Agent used for
A1: BWD Water Decoloring Agent is designed for removing color and reducing COD in industrial wastewater especially from textile dyeing dyestuff pigment printing ink paper and landfill leachate industries
Q2: How does BWD Water Decoloring Agent work
A2: It is a quaternary ammonium cationic polymer that neutralizes negatively charged dye molecules and forms dense flocs allowing fast sedimentation or flotation and efficient color removal
Q3: What types of dyes can BWD treat
A3: BWD is effective for reactive dyes acid dyes disperse dyes direct dyes and mixed dye systems including both soluble and insoluble dyes
Q4: What is the typical decolorization and COD removal efficiency
Color removal is typically 50 to 99 percent and COD reduction is usually 50 to 80 percent depending on wastewater characteristics and operating conditions
Q5: How should BWD Water Decoloring Agent be dosed
A5: The product is diluted with 10 to 40 times water before dosing It is added directly into wastewater with mixing followed by sedimentation or air flotation Jar testing is recommended to determine the optimal dosage
Q6: Can BWD be used together with PAC or other coagulants
A6: Yes BWD can be used together with PAC to optimize treatment cost and performance However they should not be pre mixed and the dosing sequence should be determined by jar testing
Q7: Does BWD produce a large amount of sludge
A7: No BWD produces significantly less sludge compared with traditional inorganic coagulants which helps reduce sludge handling and disposal costs
Q8: Is BWD Water Decoloring Agent safe to use
A8: The product is non flammable non explosive and free of aluminum chlorine and heavy metals making it safer for handling and environmentally responsible wastewater treatment
