Demanganization of Ground Water and Utilization of Water Treatment Sludge
It is told about the study of ground water biological demanganization. Factors influencing on the mechanism of manganese oxidation with iron bacteria as well as the flow chart of water treatment are presented. A comparison of the proposed biofilter design with foreign analogues is made. To prevent collection of manganese sludge the advanced treatment of them for production of a pigment, which can be used in paint and varnish materials, is recommended.
Key words: ground water, manganese, iron bacteria, demanganization, biofilter, manganese sludge.

Membrane Systems Used for Boiler Feed Water Treatment at Power Plants
Long experience of membrane reverse osmosis and ultrafiltration techniques application at Russian power facilities is described. Membrane techniques demonstrate high economical and environmental efficiencies when compared with conventional ion exchange yet require high operational costs and water consumption. Main operational costs (chemicals, electricity, membrane replacement) are attributed to pretreatment and fouling control. Main ways to improve membrane systems reliability and operational costs reduction are outlined.
Key words: water treatment, desalination, sodium-cation exchange, membrane, ion-exchange filter, reverse osmosis, ultrafiltration.

Technology of Natural Water Adsorption Treatment for Chlorophenol and Phenol
The laws, features and mechanism of adsorption have been established on the basis of study of equilibrium of phenol, chlorophenol, and chlorophenol and phenol mix adsorption from water solutions with active carbons differing in nature, structure, specific surface and method of preliminary preparation. Possibility of improvement of the process efficiency owing to the increase of adsorption capacity of active coals has been studied.
Key words: natural water, chlorophenol, phenol, adsorption treatment, active carbon.
