Biotechnologies introduction in the system of natural and wastewater treatment at dairy enterprises and settlements Available to Purchase

Dairy industry is one of the key branches of food industry in Ukraine. Water supply of most milk processing enterprises is based on using uderground waters of their quality are not always agree with technologic norms: ions of heavy metal (Fe²⁺, Mn²⁺), ammonium nitrogen, dissolved organic matter, phenols. As a result of many year experiences, authors established that the main role in providing for necessary quality of water for technology needs and also for treating wastewater in milk processing enterprises belongs to biological treatment methods. The work presents the results of researches in technology including bio-reactors and filters for comprehensive treatment of uderground water under conditions of irregular changes in specific loading, filtration rate, seasonal fluctuation of their quality and air temperature. It has been determined that the usage of modern technologies of milk processing results in reduction of drinking quality water waste along with increase in concentrations of wastewater pollutions. Possibility of effective usage of big hydraulic height metal aeration tanks with surface jet aeration for highly concentrated wastewaters treatment under conditions of change of pollutants concentration, pH values and temperature was confirmed. The paper considered one of the variants to comprehensively solve issues of water supply-water disposal for small settlements where enterprises of milk processing industry are located by way of introducing power and resources saving biotechnologies for treating natural and waste waters developed at NUWEE.
