“…In other work using bacterial lipases, Sonune and Garode (2018) reported 25% removal e ciency for COD in municipal wastewater. Haselroth et al (2021) obtained satisfactory results using Aeromonas hydrophila isolates to treat bovine slaughterhouse e uent, achieving 67.4% e ciency. Nimkande and Bafana (2022) reported that the use of enzymatic pretreatment to reduce the pollutant loading of e uent was effective due to the rapid formation of high concentrations of intermediate compounds that could be more easily degraded in subsequent treatments, whether anaerobic or aerobic.…”

The use of microorganisms to treat effluents can reduce problems caused by oils and fats in subsequent treatment stages. The present work investigates the use of a lipase-producing microorganism in the pretreatment of effluent from a fish slaughterhouse. Initial preliminary tests were performed with two microorganisms: Staphylococcus warneri and Bacillus megaterium. The following parameters were evaluated after the treatment: chemical oxygen demand (COD), oils and greases (O&G), and lipolytic activity. Bacillus megaterium provided the highest removal efficiencies for the analyzed parameters, consequently this microorganism was then used for the pretreatment of fish slaughterhouse effluent. A central composite rotational design (CCRD) was applied, with pH, temperature, and inoculum concentration as the independent variables. The response variables were lipolytic activity, COD, O&G, free fatty acids, and pH, for a reaction time of 72 h. The maximum values obtained after the treatment were lipolytic activity of 0.25 U mL− 1, COD and O&G removals of 61.11% and 85.8%, respectively, and free fatty acids production of 12.54 µmol mL− 1. The findings showed that the application of Bacillus megaterium significantly reduced the levels of oils and fats, demonstrating the potential of the enzyme for treatment of this type of effluent.

Oil and grease are organic contaminants that are detrimental to the environment. The high concentration of oil and grease can cause clogging in the sewer. Clogged sewers can deteriorate sanitary conditions. Adsorption is one technique to reduce oil and grease concentration in wastewater. Adsorption using natural resources can overcome the high cost of commercial activated carbon. Sewage sludge has potential as raw material for activated carbon because of the high carbon content. The studies aim to investigate the capability of activated carbon derived from sewage sludge to remove oil and grease from restaurant wastewater. The studies were carried out in the batch experiment. Adsorbent dosage ranged from 2-6 g/L, and a contact time range of 5-45 minutes was performed in the experiment. Sewage sludge was chemically activated using KOH 4M and physically activated at a temperature of 700°C for 60 minutes. The result shows that the optimum adsorbent dosage and contact time are 4 g/L and 25 minutes, respectively. The highest adsorption capacity of sewage sludge to remove oil and grease was 63.75 mg/g. Under observed data, the adsorption fit the second-pseudo-order, and Langmuir isotherm indicated that the adsorption process was chemisorption.
