Dear Mr Muntjeer, Some years ago, I made jar tests and one trial with DAF pilot plant for two cosmetic industries. The COD was in both cases around 25000 30000 mg/l and Fats around 1500-2000 mg/l. Minimum COD removal was 60% and the average 75%. Minimum Fats removal 70% and the average 90%. The chemical consumption and floated sludge production was high. I don’t know your daily flow but normally for cosmetic industries the flow is relatively low. DAF as primary treatment can be a solution and the following aerobic treatment plant works well but the sludge disposal is problematic. I think that must be studied also the possibility to apply an evaporator or an anaerobic reactor.
