The work is devoted to the study of the possibility of waste water from the lipid concentrate (oil) obtained on the basis of the larvae of the Black Soldier fly (Hermetia Illucens) production treatment. Treatment of oily wastewater is not an easy task due to the specific properties and condition of the oils contained in such wastewater. Typically, wastewater containing fats and oils has a high chemical oxygen demand (COD), biological oxygen demand (BOD), large amounts of suspended solids, oils, fats, phosphates and sulfates. Various physicochemical methods are used to treat such wastewater. However, the search for inexpensive effective materials for the oils extraction from aqueous media is an actual task.
For cleaning, we used the crushed fruits of the Sycamore tree – a deciduous tree widespread in the southern strip of the Russian Federation. Model emulsions containing "Black Soldier" larvae oil were subjected to cleaning. The influence on the purification efficiency of such factors as the dose of the sycamore fruit (SF) added biomass, the SF interaction duration with the emulsion, and the pH of the medium was investigated. It was found that high purification efficiency is achieved at the SF dose of 1 g per 10 cm3; pH = 4; the duration of the contact is at least 10 minutes.
