Investigating the efficiency of using corrosion inhibitors for conditioning of water with high salt content


The results of experimental investigations in one of the recycling water supply systems at the gas processing plant experiencing the problem of high-rate biological growth are presented. Recycling water from the system was characterized with high salt content, high chloride and sulphate concentrations. The use of inhibitors in water treatment provides for reducing the corrosion rate in heat exchangers and pipelines.

Assessment of the Sanitary Hazard Degree of Silicon Compounds in Natural and Potable Water


The survey of literature on the role of silicon in the human body, its toxicokinetics is conducted; the critical analysis of scientific substantiation of hygienic standards of maximum concentration of silicon compounds in natural and potable water is made. The attention is paid to the absence of standards concerning the silicon content in water in the foreign standard specifications because of non-actuality of the problem. It is proposed to cancel the standard of limit content of silicon in the domestic normative base in connection with the absence of its proper reasonableness.

Solving the problem of waste discharge of stand-alone industrial facilities


Advanced technologies of wastewater non-biological treatment with reverse osmosis are presented. Formation of concentrate in the process of reverse osmosis is a most difficult problem. The suggested technology provides for the reduction of concentrate flow to less than 1% of the total waste flow subjected to treatment (corresponding to the activated sludge flow removed to sludge beds at biological treatment facilities). Since the concentrate flow depends on the salt concentration in wastewater to be treated it is recommended to supply water with low salt concentration to the water supply system of the facilities. The comprehensive approach to the problem of reducing the discharge of industrial wastes in the environment specifies the use of membrane units for water conditioning (in boiler-houses), drinking water treatment, wastewater treatment and reuse as process water (in irrigation, in heating systems).
