SOME ASPECTS OF THE TREATMENT OF OILY WASTE RESULTING FROM THE STORAGE OF FUELS AND LUBRICANTS
Cleaning msutoday wastewater from storage tanks, fuel oil boiler engineering enterprises is an urgent task. In the construction of local treatment facilities promising is the application of pressure hydrocyclones and hydrocyclone units. The article presents the results of research msutoday purification of waste water in the pressure hydrocyclones hydrocyclone carried out on the experimental rig including the test pressure hydrocyclone, soothing capacity, capacity for receiving water from the upper and lower drains of the hydrocyclone. The studies tested seven modifications of pressure hydrocyclones with a diameter of 40 to 100 mm with different diameters of the nozzles of the upper and lower drains. As a result of experimental researches it is established that the efficiency of wastewater treatment in the pressure hydrocyclones for oil products amounted to 54-77 %, and suspended solids 49-67 %. It is established that the hydrocyclones with a diameter of 40 mm have a high cleaning efficiency NSV, but small capacity, and hydrocyclones with a diameter of 100 mm have better performance, but for their effective operation requires a greater inlet pressure in the hydrocyclone. Msutoday for cleaning wastewater generated in the storage tanks of fuel oil, recommended a hydrocyclone with a diameter of 75 mm. the results of the research have been used when designing industrial installations for cleaning msutoday wastewater.
