The process for producing bio-diesel first extracts lipids from sludge produced during primary and / or biological treatment of municipal wastewater, agricultural wastewater and industrial wastewater using primary, secondary and tertiary treatments, followed by extraction. Lipids were invented by transesterification with alcoholic esters using transesterification. The resulting product from this process includes bio-diesel, glycerol, lipid-free proteins, various other useful chemicals and aqueous based substrates suitable for optimal digestion in subsequent biological digestion (aerobic or anaerobic). Lipids extracted from sludge containing high levels of microorganisms are phospholipids that can also be used directly as lecithin. Extraction of lipids from the sludge will be carried out using chemical extraction techniques with basic, acidic and / or transesterification of the extracted lipids achieved using a combination of these two ester exchange techniques. |
