New opportunities in disposing chemical water treatment slurry in thermal power plants

This paper examines the disposal of liquid waste – chemical water treatment slurry obtained in the thermal power plants (TPP).The slurry is formed at the stage of water pre-treatment which includes water clarification, as well as reductionof oxidization, alkalinity, and partial desalination.

Effect of water factor on human health status   

The current ideas on the role of water factor in developing population health status are outlined. The scientific findings on effects of chemical and biological composition of water used are provided from the viewpoint of the character and the level of contagious, non-contagious and parasitic disease morbidity as well as the rate of abnormal genetic conditions. The new optimization approach to evaluate microelement composition in drinking water is examined. The impact of inherent hydrobiological processes on water quality in intake reservoirs is analyzed. The basis of modern approach tosetting forth standards on water quality to be used for drinking, communal or recreational purposes is reviewed.

Keywords: population health status, water factor

Lazur technology – a new step in water supply and sewage decontamination    

Process Lazur developed in CJSC «Svarog» is based on using of combined effects of UV radiation and ultrasound in water supply and sewage decontamination units. Current research substantiates efficiency of this approach providing new experimental data obtained in comprehensive operational and microbiological testing of mass-produced «Lazur-M» units. The data was obtained in profile laboratories in Russia, South Africa, Australia and New Zealand.

Keywords: «Lazur» process, ultrasound, UV radiation, water decontamination

Activation of bioflocculating water treatment processes in permanent magnetic field

The article addresses the issue of intensifying the agent-free methods of primary water treatment through exposure to permanent magnetic field (PMF). The theoretical basis of effect of PMF having different strength on outcome of water bio-treatment is analyzed. The experimental methodology is outlined and results obtained are given.

Keywords: agentfree methods, permanent magnetic field, water treatment

Polyphosphate contamination as an underlying cause of mass reproduction of cyanobacteria in reservoirs

The paper examines the environmental impact of using tripolyphosphate as a component of synthetic detergents. Release of phosphorus compounds with waste water into water reservoirs results in mass growth of blue-green algae (cyanobacteria). Toxic compounds produced by the cyanobacteria pose a risk to humans and animals. The necessity to take proactive steps to prohibit using polyphosphates in detergents at the territory of the Russian Federation is substantiated.

Keywords: cyanobacterial toxins in the water environment, tripolyphosphate

Method to calculate the water supply tariff investment component accounting for the company profile

The issue addressed deals with validating the income associated with charging service tariffs for the companies providing water supply and sewage removal services. The proposed approach to calculate the tariffs is based on the operationalstatus of fixed assets of the service company.

Keywords: housing and public utilities, income, investment tariff component, profitability, water and sewage utilities

Microbiological criteria to asses drinking water quality

This article provides the results of drinking water quality studies using microbiological criteria set forth by various authorities. It has been shown that the majority of water samples does not meet the requirements of regulatory documents on the content of microorganisms.
