constant pH, or pH and concentration of the feed solution. To obtain data for scaling, it is necessary to apply a fixed voltage on the stack and to use a constant flow rate of the feed solution during the experiment, the feed solution concentration may vary with the time. Specifications of the stacks studied, rational hydraulic and electrical modes of testing are considered. E.V. Laktionov, N.D. Pismenskaya, V.V. Nikonenko and V.I.

tert-butyl ether (MTBE) by pervaporation (PV). It was prepared from CTA hollow fibre reverse osmosis (RO) membranes used for the desalination of brackish water with high salinity. Acetone was selected as a modification agent of the CTA membrane. PV performance depended on the solvent concentration, the treatment time and modification temperature of CTA RO membrane that was soaked in the aqueous acetone. The results show that a CTA hollow fibre membrane, modified with the solvent, has a superior performance both in terms of the separation factor and the permeate flux during the PV experiment conditions.

Characteristics of thin-film nanofiltration membranes at various pH values Salt rejection and ion selectivity of NF-255 and NF-45 nanofiltration (NF) membranes were investigated. The rejection of two cations (Na+, Ca2+) and two anions (Cl–, SO42–) which are common in natural and in industrial wastewater, were studied as a function of pH at permanent pressure and temperature. The ion rejection of NF membranes was investigated in single salt solutions such as NaCl, CaCl2, Na2SO4 and CaSO4, and in multi-component systems that contained all the previous ions. The authors found that there is a minimum rejection of the Na+ and Cl– ions at pH 4–5 in NF-255 and at
