Improving the efficiency of water recycling systems at oil refineries and petrochemical enterprises (part 2)

Summary

Comprehensive studies were carried out to improve the efficiency of water and wastewater treatment facilities at one of the oil refineries in the Southern Federal District by adding one or more stages of tertiary treatment; by improving the design of the existing facilities; and replacing the technological process of one of the treatment stages for a more efficient one. Research objectives: 1) analysis of the operation of the water recycling systems (units), existing wastewater disposal and treatment facilities; 2) development of the optimal solutions and schemes for upgrading the recycling water supply of the enterprise; 3) development of technical measures aimed at increasing the efficiency of the water recycling system, reducing the volume of wastewater discharged by the plant and reducing the amount of raw water abstraction by arranging the makeup of the existing water recycling units with effluent. The previous article on this topic presented the research materials on the first two tasks.

Key words

sewerage treatment facilities , water recycling facilities , industrial wastewater treatment , zero discharge system , pilot tests , feasibility study
