Probiotics as one of methods for dairy wastewaters' treatment intensification

Abstract

Despite the rapid production growth, creation of new technologies improving production quality, the problem of increasing amounts of wastewaters with specific composition and qualities has not solved yet. Wastewaters formed at dairy plants have high concentrations of some contaminations. Qualitative indices of these wastewaters, such as pH, COD, anionic surfactants, nitrogen and phosphorus compounds, differ dramatically from domestic wastewaters' ones. Wastes and product residuals, dumped into sewage system, aggravate this situation. Nowadays, many plants do not have any local treatment plants, which can cope with polluted effluents, while existing ones cannot provide with required degree of wastewater treatment. This article presents the research of probiotics' influence on the qualitative composition of dairy wastewaters using Belgian probiotic "Pip Plus WATER". Besides, based on the experimental research results, a technological scheme of local treatment plant that can be realized at dairy plants is proposed.
