Water disperse system investigation by photonic correlation spectroscopy

There has been made analysis of different waters in Tomsk Region (Tomsk, Novosibirsk and Vladivostok towns). Natural and mineral water has been analyzed by photonic correlation spectroscopy during their heating. For all samples particle upsizing takes place while temperature increases. The tendency is the same in model systems based on CaSO4 and MgSO4 salts. «Hardness salts» were suggested to act as dispersed phase.

Keywords: photonic correlation spectroscopy, size of particles, water

Theoretical aspects of ion-molecule buffer capacity in natural waters in equilibrium with gibbsite

New theoretical approach has been developed for ion-molecule buffer capacity estimation, βX, in acid natural waters in equilibrium with gibbsite. The approach includes buffer estimation βH and βAl in natural waters, taking into consideration dominance of Al buffer value. Influence of different factors such as temperature, pH, and main component concentration on buffer characteristics of two-phase systems has been studied.

Keywords: buffer capacity, gibbsite, natural waters

Natural water control in sustainable development

Freshwater basin capacity for self-purification has been overviewed. It is reached by biological cycle including organic matter creation, transformation and decomposition implemented by trophic (food) connections of bacterial, animal and plant worlds. Every natural aquatorial and bottom complex is shown to have its own self-purification load in the process of water basin purification. Therefore zoning and comprehensive analysis of underwater landscape is of a big importance. From this point, nature conservation activity should be based on detection of complexes with the heist self-purification capacity, maintenance of their activity and broadening of their areas.

Keywords: algae, basin self-purification, higher aquatic vegetation, hydrobionts, maximum permissible concentration, natural water quality, sustainable development, toxicological load, toxicoresistance of water animals, water control

Pollution of water environment by hydrocarbons: risk, prevention and remediation

Data on the most considerable emergency floods of hydrocarbons (oil and gas condensate) to water environment in various regions of the country have been presented. The risk of water environment pollution by hydrocarbons has been proved. The prevention and remediation measures on warning of emergency floods of hydrocarbons to water environment and liquidation of their consequences are described.

Electrodialysis desalination plants based on interpolymer membranes

Effective methods for interpolymer ion exchange membrane synthesis with modified physical-mechanical and electrochemical properties has been developed. Their basic physicochemical properties have been investigated using pilot electrodialysis cells. As a result electrodialysis apparatus for water separation from organic liquids has been constructed with description of its operating principals.

Keywords: electrodialysis, membranes, selectivity, static exchange capacity

Wastewater post-treatment from nitrogen and phosphorus compounds by macrovegetation

Possibility of using water plants of Ceratophyllum stem for domestic wastewater post-treatment (after biofilter treatment) from biogenic substances has been estimated. There have been carried out experimental studies of peculiarities of nitrogen and phosphorus compound removing from wastewater by macrophytic assemblage and microbiocoenosis.

Polyhexamethyleneguanidine hydrochloride as reagent-oxidizers alternative for water purification and disinfection. Part 1.

Polyhexamethyleneguanidine hydrochloride properties have been characterized. This polymeric biocidal substance with broad spectrum of operation is currently used in many disinfectant agents (more than 60). Possibility of using polyhexamethyleneguanidine hydrochloride as biocidal flocculant for effective and safe water disinfection has been shown. Positive experience of the Ukrainian coworkers on polyhexamethyleneguanidine hydrochloride usage as nonoxidizing reagent for water disinfection has been declared.

Keywords: alternative approach to water disinfection, drinking water, polyhexamethyleneguanidine hydrochloride, альтернативный метод обеззараживания воды, питьевая вода, полигексаметиленгуанидин гидрохлорид

Azo dyes and aromatic amines degradation by methanogenic microbal assemblages isolated from sludge treatment facilities

From methanogenic sludges of treatment facilities microbal consortiums with high decomposition rate of azo dyes and aromatic amines have been isolated. Decalorizing process and destruction schemes of three azo dyes have been presented. Sulfanilic acid and 1,4- phenylenediamine provided methanogenesis were shown to be resistant to destruction and to accumulate in the environment. The difference between morphological characters of original sludges and sludges adapted to aromatic substances of microbal community have been revealed. The process of aromatic amines biodegradation has been described.

Keywords: aromatic amines, azo dyes, biodegradation, methanogenic sludges

Bioagent based on hydrocarbon-oxidizing strain Phyllobacterium myrsinacearum DKS-1 for oil polluted areas purification

On the basis of hydrocarbon-oxidizing strain Phyllobacterium myrsinacearum DKS-1 isolated from shelf waters of the Caspian Sea, bioagent «Phyloil» has been developed both in liquid and dry forms on substrate bearer. Bioagent tests has shown efficiency of its application for sea water purification from oil hydrocarbons including polycyclic aromatic hydrocarbons.
