The thermodynamics of cloud point extraction (CPE) of three different dyes are investigated. Dyes used are congo red, eosin and chrysoidine. Iso-octyl phenoxy polyethoxy ethanol (TX-100) and octyl phenol poly ethylene glycol ether (TX-114) are used as non-ionic surfactant. The effects of different o

A combination of adsorption and nanofiltration (NF) was adopted for the treatment of a textile dyehouse effluent containing a mixture of two reactive dyes. The effluent stream was first treated in a batch adsorption process with sawdust as an adsorbent to reduce the dye concentration of the effluent
