The treatment of wastewater produced in a textile factory during dyeing of cotton with reactive dyes was performed using membrane filtration. The separation efficiency was determined using membranes for nanofiltration (NF) and for reverse osmosis (RO). Ecological parameters (COD, pH value, conductivity and SAC) were determined for wastewater samples before and after filtration. The dyed fabric was evaluated with qualitative parameters and by determining the pH value of the water exstract. The research results show that the permeate can be reused in the dyeing process.

The aim of this investigative study was to determine the presence of rotaviral RNA at various critical control points (CCP) of a hospital laundry. One of the possible sources of hospital infections is inappropriately laundered and disinfected hospital textiles. Rotaviral was found on various laundry surfaces: technical equipment, storage shelves, transport vehicles, personells hands, damp textiles and folded laundry. Based on the results, it is very important to take into consideration the proper handling of textiles after washing as one of the precautions against hospital-acquired infections.
