Wastewater is considered to be difficult to treat biologically when F = BOD 5 /COD is lower than 0.3. Most of the samples under consideration present a poor initial biodegradability , which increases significantly after treatment, except for two samples (WW3 and WW5). 3.2. UV photocatalytic degradation of textile wastewater
wastewater in the textile factory is that it provides partial or full re-use of water. Produced waste water has to be cleaned from, fat, oil, color and other chemicals, which are used during the several production steps. Figure 2. Various methods for the treatment of wastewater from textile plants The treatment processes may be categorized
