Selective flocculation of iron oxide-kaolin mixtures using a modified polyacrylamide flocculant
Bulletin of Materials Science, 1988 High molecular weight polyacrylamides were synthesized and successfully modified to contain up to 8·3% hydroxamate functional groups. The selective flocculation tests carried out on 1:1 iron oxide/kaolin mixtures using parent polyacrylamide, polyacrylic acid and the modified polyacrylamide, confirm the possibility of enhancing selectivity through ...

Treating mechanical washing wastewater with iron-in-oil characteristics by changing the fate of iron
Water Science and Technology, 2023 The mechanical washing wastewater contained a large amount of oil, and the iron wrapped in the oil was slowly released into water. This caused the effluent quality to fluctuate, causing common polymeric aluminum chloride (PAC) to ineffectively remove the

Purification of Tannery Effluent by electrolytic corrosion of aluminium [PDF]
, 2006 Tannery Effluent is noxious because tanning process chemicals are preservatives, including chromium, and the pH is high. Electrolytic processing is feasible because the high salt content gives a high electrical conductivity. While research on the subject
