Interaction between intraformational treatment and bank filtration in the process of water treatment at the Tungus water intake facilities
Summary
In the process of choosing the best available technology of ground water treatment of the Tungus water deposit the preference was given to intraformational treatment at the artificial geochemical barriers. The hydrodynamic calculations show that after the design capacity is reached the main part of the water intake inflow will come with the surface runoff in the form of bank filtrate; thereby the evaluation of the interaction between intraformational treatment and bank filtrate is an urgent task. Various aspects of interaction and mutual effect of the two underground water treatment technologies are considered. Examples of the combined use of the two methods in Russia and abroad are presented. The assessment of the bank filtrate effect on the process parameters of the intraformational treatment is presented. For this purpose the hydraulic and hydrodynamic aspects and changes in the qualitative composition of the mixed water are analyzed.

Protecting underground water intakes from chloroganic pollution
Summary
Recent investigations carried out both in Russia and abroad witness wide spread occurrence of chlororganics in underground waters originating from different pollution sources. The data on the advanced intraformational technologies of protecting underground waters from dissolved cholorganic forms are presented. On the basis of numerical model studies the possibility of applying some of the technologies in actual practice are evaluated.

On the criteria of choosing the best available water treatment technology as applied to the Amur water intake (Komsomolsk-on-Amur city)
Summary
While choosing the technology of underground water conditioning it is advisable to be geared to the recommendations in SP 31.13330.2012 «Water supply. Public utilities», «Classifier of natural water treatment technologies» (NII VODGEO, 2000) as well as to minimizing the environmental impact. It is shown that intraformational treatment of underground waters meets to the maximal extent the requirements to the best available technologies and domestic standards developed on the basis of ISO 14000 International Standard. By the example of the Amur water intake of Komsomolsk-on-Amur city the complete conformity of the designed technology of intraformational iron and manganese compounds removal to the above-mentioned criteria with account of the specific water composition is noted. In discussing the specific features of underground water chemical treatment the attention is drawn to the inadmissibility of large-scale use of precursor – potassium permanganate for water conditioning. It is suggested to evaluate additionally the water treatment technology with account of the economical efficiency.

Experimental-industrial operation of a pilot plant for intraformational ground water purification at the Tungus intake facilities
Summary
The results of experimental-industrial tests of a pilot plant for intraformational water deironing and demanganization at the Tungus ground water intake in Khabarovsk are presented. The ground waters of the Tungus deposit are characterized by high content of iron, manganese, and dissolved carbon dioxide at low pH values. The pilot plant included three operating and 14 observation wells. The positive impact of artificial recharge of the aquifer in the operation area of the intraformational water purification at high pH and dissolved oxygen levels is shown. Based on the results of the water qualitative composition analyses of the observation wells located at various distances from the operating wells a schematic view of the sedimentation area around the operating wells is given. Based on the pilot plant operation results a working draft of the intake with the intraformational purification capacity of 106,000 m3/day was designed. At present the first section of the water intake with a capacity of 25,000 m3/day has been completed.
