In recent years, many researchers have focused on microalgae as a potential source of lipids for various purposes. To improve the lipid yield, different biomass pretreatments have been investigated. The aim of this work was to determine the effect of an ultrasound and deep eutectic solvent (DES) pretreatment on lipid yield from green microalgae Chlorella sp. The chosen DESs were choline chloride:urea (ChCl:U), choline chloride:glycerol (ChCl:G), and choline chloride:acetic acid (ChCl:Aa) all at the molar ratio 1:2. Lipids were extracted from the pretreated and untreated biomasses by Bligh and Dyer?s method. The results showed that the lipid yields for the untreated and ultrasound-pretreated biomass were 39% and 48%, respectively. The pretreatments with ChCl:U, ChCl:G, and ChCl:Aa resulted in lipid yields of 51%, 46%, and 40%, respectively. Therefore, the use of efficient and environmentally friendly DESs for the microalgae biomass pretreatment resulted in a higher lipid yield.

The sorption properties of the residual biomass of microalgae Chlorella sorokiniana, which is formed after the extraction of lipids, were investigated. Residual biomass is waste and is used for wastewater treatment from iron(III) ions. Microstructural studies of Chlorella sorokiniana microalgae and residual biomass after lipid extraction were carried out. The purification of model wastewater from iron(III) ions under static conditions has been studied, the purification efficiency and adsorption capacity of the residual biomass of Chlorella sorokiniana have been calculated. A model filter was created, where residual biomass of Chlorella sorokiniana was used as a filtering load and sorption processes were studied under dynamic conditions. The efficiency of purification of model wastewater from iron(III) ions has been calculated and a comparative analysis of the effectiveness of purification under static and dynamic conditions has been carried out. A method for the disposal of spent sorbents as an additional fuel is proposed. The specific heat of combustion (q = 20,674 kJ/kg) of the spent sorbents from the residual biomass of microalgae Chlorella sorokiniana, the value of which is not inferior to traditional energy sources, was determined experimentally.
