Abstract
Experimental results of preliminary treatment of oily liquid wastes generated at enterprises during maintenance of storage tanks for combustible and lubricating materials, repair and maintenance works, washing products that have worked with different lubricants directly at the place of their formation by means of a compact mobile unit including a filter with a sorption material loading, a chamber with a settling tank placed in it, and a nutsch filter for separation and dehydration are presented. Suspended substances, non-emulsified fats, oils and emulsified petroleum products from the aqueous phase are removed by filtering through sorption material based on polypropylene and emulsified and dissolved petroleum products are settled in the reactor-settling tank on the surface of coagulants – iron or magnesium hydroxides. The efficiency of pretreatment from mechanical impurities and non-emulsified petroleum products was close to 100 %, emulsified and dissolved petroleum products > 98,7 %.
