Enertek is experienced in the inspection, adjustment and development of the water chemistry conditions of circulation water supply systems. The feasibility of these measures is conditioned by the problems that are quite common in these systems, associated with the formation of sediments on heat exchange equipment and corrosion processes of metal structures in contact with cooling water. In addition, most enterprises today seek to optimize the operation of circulation systems in order to save fresh water, chemical reagents (in the presence of reagent treatment), as well as reduce wastewater. Recently, due to the requirements of various environmental organizations, oil refineries tend to reduce the intake and use of fresh water and increase the share of recirculated water supply. One of the directions in solving this problem is the use of wastewater generated at the plant, after their appropriate purification, as an additional feeding for circulation water supply systems. This reduces the intake of fresh water, as well as the amount of wastewater discharged by enterprises into the reservoir.
As part of the work on circulation water supply system, Enertek carries out a set of works on the study of the water chemistry conditions, the development of measures aimed at optimizing the existing reagent treatment and reducing wastewater. The minimum permissible discharge into the wastewater storage is calculated, on the basis of which the performance of the wastewater treatment plant is determined. Enertek has developed a technological scheme for advanced wastewater treatment to feed waste water boilers and the circulation water supply unit. In addition, we offer a modern highly efficient technological scheme for wastewater treatment, based on membrane bioreactors, with the need for preliminary testing of the technology using a pilot plant in the conditions of existing production (without stopping the production process).
