Membrane scaling during water desalination by membrane distillation has been studied. A tap water was applied as a feed and diluted HCl solutions were used for periodical cleaning of module. The membrane morphology and the composition of deposits were determined using scanning electron microscopy co

Demineralisation of tap water, produced from surface water (lake), by a membrane distillation process has been investigated. The temperature caused the decomposition of bicarbonates presented in the feeding water and the formation of alkaline scaling on the membrane surface. In the present work the

The treatment of effluents from the regeneration of cation exchanger by the membrane distillation (MD) process has been investigated. The composition of these effluents is complex due to the content of residual acid (1–50 g HCl/dm3) and different amounts of various salts (ranging in concentration fr

The membrane distillation (MD) process for the treatment of wastewater from ion-exchanger regeneration was proposed. The precipitation of salt deposits on the membrane surface was observed when such wastewater was directly used as a feed. A rapid decline of the permeate flux from 532 to 410 dm3/m2d

The production of demineralised water from drinking water by nanofiltration/membrane distillation system (NF/MD) has been investigated. The precipitation of CaCO3 on the membrane surface and a rapid flux decline was observed when tap water was used directly as a feed. The problem of scaling was elim

The tap water is often used as water source for different industries, however, the water repurification is required to meet the specification of technology. The effect of application of ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) and membrane distillation (MD) processes on the qu
