Tags: , , , ,
  • How can industrial effluents be treated?
  • The combination of conventional treatments with modern techniques can improve the performance of removing oil presenting all types of compositions and a range of particle sizes. To be considered successful, the treatment of industrial effluents, particularly those from the oil industry, must be sustainable, biocompatible, and biodegradable.
  • What are oily industrial effluents?
  • Oily Industrial Wastewater Effluents contaminated with oily particles are usually associated with mechanical, automotive, and thermoelectric industries, as such effluents are a result of processes that use derivatives of fossil fuels, such as gasoline, diesel, and low-pour-point oil.
  • What is petroleum sludge?
  • Petroleum sludge is a solid emulsified waste and contaminant commonly produced in the petroleum industry. In the recent past, there has been increased business growth in the oil sector, resulting in increased volumes of oily sludge characterized by high viscosity and toxicity. Therefore, sludge treatment before discarding is extremely necessary.
  • How is petroleum effluent treated?
  • In the treatment of petroleum effluent, a combination of traditional and common techniques such as biological, physicochemical, and chemical approaches are employed. Physical (mechanical) pre-remediation is often used to remove free oil, grease fractions, and suspended particles from petroleum effluent.
