Correlation between Diameter of Microorganisms and Efficiency of Microorganisms Destruction under Gas/Cavitation Conditions

The values of еffective rate constants of microorganisms destruction (kd) were compared, depending on the diameter of cells and gas nature bubbling under cavitation conditions. The efficiency of cell destruction under Ar/US is larger by 2–2.5 times compared to He/US, O2/US and CO2/US. Yeast cells were destroyed faster than bacteria (kd (yeast cells) >> kd (bacteria cells)) that is explained by the cells size. The cell stability under cavitational conditions is reversely proportional to the cell diameter.

Gas Nature Effect on the Destruction of Various Microorganisms Under Cavitation Action

The disinfection of water from Diplococcus, S.lutea, B.cereus, and Ps.fluorescens bacteria types and the yeast Sacch.cerevisiae via the joint action of gas/US has been investigated. The investigated microorganisms were identified in natural water and wastewater in dominant amounts. The relative ranges of effective cell destruction by combined gas/US action have been established.

ENHANCEMENT OF ENVIRONMENTAL SECURITY OF DESTRUCTION PROCESSES OF WATER POLLUTANTS IN ECOSYSTEMS OF WATER TREATMENT PLANTS

At present, mechanical, chemical, biochemical and physicochemical methods of cleaning are developed and efficiently used to protect water bodies from sewage pollution. The methods of biochemical wastewater purification from organic contaminants with the use of activated sludge have received the highest recognition. Getting of additional nutrients (nitrogen, phosphorus, potassium) and other trophic precursors into the aquatic ecosystem directly leads to immediate biohydrogenase reaction of increase in the number and biomass of the primary producers of organic matter.

Problem deviations in the legal system socio-cultural changes

On the basis of a thorough analysis of scientific papers highlighted the problem of deviations in the legal system of social and cultural change. It was found that the phenomenon of deviance ambivalent nature and can mean both negative and positive social change. In the scientific literature rejection divided into primary and secondary. Those terms that society is negligible, considered primary, and subjects who commits them, do not qualify as devianta because they do not violate social norms.
