The invention is based on biofilter filled with the combination of sand and layered nonwoven textiles for removal of dyes, organic pollutants and salts from coloured textile wastewaters. The principal invention of combined biofilter is increased treatment efficiency due to the larger and rougher structure of nonwoven textiles surfaces, which are suitable for biomass growth.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 15730198The main purpose of the presented study was to examine the potential of various biomass natural supports such as polypore mushrooms, limestone, zeolite and granulated peat to decolorize wastewaters, regarding various parameters such as wastewater characteristics (different dyes, pH medium and chemicals) and retention time. Results showed different treatment capability depending on the type of biomass support and the type of waste baths. Polypore mushrooms and granulated peat were the most effective for the treatment of highly alkaline waste baths; meanwhile limestone showed the highest activity for waste baths containing C.I. Acid Blue 158 and zeolite for baths containing the C.I. Reactive Yellow 15.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 15134486With this research we want to determine the quality of dye-rich textile wastewaters after treatment and decoloration with advance oxidation processes and membrane technology for re-use in finishing processes as well as the influence of treated wastewaters on colour and colour strength after repeated dyeing.
