Petrochemical and Refineries

Effluents from refineries are complex and specific treatment methods are required to remove contaminants such as oil, phenols, benzene, toluene, ethyl benzene, xylenes, sulfide, ammonia, PAHs and heavy metals prior to discharge or recycling. Phenol and its derivatives have long been recognized as some of the most persistent chemicals in effluents such as petroleum refinery wastewaters, with high toxicity even at low concentrations

Biodegradation of these compounds by microbial species is very difficult owing to the size, nature and complexity of the intermediates formed. RichEcosol enzyme technology helps reduce phenol into simpler intermediates and finally, with the help of microbial systems, convert the same to water and carbon dioxide, thereby reducing the toxicity and chemical oxygen demand
