Polymeric membrane flat sheets as well as hollow fibres are widely used in membrane bioreactors in order to separate biologically cleaned water from suspended solids. The polysulfone (PS) flat sheet and polyethersulfone (PES) hollow fibre membranes have been chosen for characterization and to invest

Concentration and purification of lignosulphonates (LS) present in spent sulfite liquor (SSL) obtained from the paper industry were carried out through ultrafiltration (UF). The salts of lignosulphonic acid, a product of acid hydrolysis of lignin, are a major component of technical LS. In respect of
