Domestic technologies and equipment for chemical free treatment of water and wastewater of the Siberian cities and industries


The chemicals used in liquid and gaseous media treatment and purification either stay intact in the processed environment or disinteg­rate and react with the processed environment or admixtures in it and form numerous secondary and often toxic products. In this context chemical free methods of media purification aiming at their environmental safety are of most interest. Chemical free methods of treatment do not result in the formation of such a big amount of secondary products; whereas the efficiency of their use is often higher because they less depend on the type and structure of the targeted substance or admixture as well as on the conditions of use. Ultraviolet irradiation has been the most efficient and widely used method of chemical free disinfection of effluents both in Russia and abroad. The capital expenses for UV-disinfection are significantly reduced since there is no need in constructing contact tanks for chlorination and dechlorination; in addition the absence of chemical consumption eliminates the need in constructing a chemical plant and installing dosing systems. Using the example of the Siberian Region the advantages of using UV-irradiation in wastewater treatment is described.
