The entry of mercaptans into the environment as an odor pollutant has always been considered as one of the environmental concerns. In this research, a sonochemical oxidation (sono-Fenton) method was used for rapid deodorizing of tert-butyl mercaptan (TBM) contaminated soil. The design of the experiments was conducted by CCD method and the effect of four different factors was investigated on the...

Abstract Coconut shell contains several components of biomass including cellulose, lignin, and pentosan, which can be used in the form charcoal as a bioabsorbent. Sludge waste is residue formed by-product wastewater treatment at plant (WWTP). emits odors that disturb local residents. This study aimed to deodorize ice cream slurry using coconut activated carbon odor adsorbent. The ratio each ads...

In modern conditions of vegetable oil processing, the issues improving quality and safety refined oils remain relevant. It has been noted that most effective one is complex or complete refining oils, which ensures removal main groups related substances by traditional improved methods. The complexity organization technology associated with accompanying oxidation at certain stages a decrease in t...

A biofilter inoculated with Arthrobacter sp. was applied to the simultaneous elimination of trimethylamine (TMA) and ammonia (NH3) from the exhaust air of swine waste storage pits. The results showed that the biofilter achieved average removal efficiencies of 96.8+/-2.5% and 97.2+/-2.3% for TMA and NH3, respectively. A near-neutral pH (7.3-7.4) was maintained due to the accumulation of acid met...

• A review of waste fats, oils and greases (FOGs) enzymatic hydrolysis is carried out. Waste FOGs potential industrial interest as oleochemical feedstock are described. Main challenges on the residual lipids explained. Developments lipase immobilization, combination, engineering revised. Intensification processes for The increasing global generation oils, resulting in a cascade economic, enviro...

Abstract Pumpkin seed oil, also called as pepita oil can be a substitute of conventional edible now days. A method has been developed to use this under-utilized pumpkin which is common vegetable in Bangladesh. This study suggests finding new alternate well proper utilization nutritionally rich rather than wasting into the environment. was extracted from dried by expeller and it purified refinin...
