Oily waste causes irreparable harm to the environment. Of the existing technologies for
treating this waste, thermal processes are the most effective, with enormous energy costs in
producing and disposing of the waste produced. Petroleum wastewater treatment techniques and
technologies included physical, chemical, and biological treatment processes.
The system of physical treatment is the main stage of treatment that is necessary for removal
or separation suspended solids (SS), immiscible liquids, solid particles, suspended solids from oil
wastewater using sedimentation, coagulation and flocculation and long-term use secondary
processing unit.
Chemical treatment involves using a chemical reaction or series of reactions to raise the
quality of the water. Neutralization is a chemical procedure that is frequently employed in industrial
wastewater treatment operations. Neutralization is the process of bringing pH levels back to
neutrality by adding an acid or base. Lime is a base, hence it is occasionally used to neutralize acid
wastes.
Biological treatment techniques can be classified as aerobic or anaerobic depending on the
presence of dissolved oxygen. Unpleasant colors and scents are produced in water in anaerobic
systems by the products of chemical and biological reactions. Which is why, the oxygen content of
water was crucial to lowering unpleasant colors and odors. Use bacteria as the primary
microorganism in the biochemical breakdown of wastewaters to produce stable end products.
The treatment of petroleum wastewater is divided into two phases. The first step is pre-
treatment, which reduces grease, oil, and suspended contaminants. Second, an advanced treatment
step is used to breakdown and reduce contaminants to permissible discharge levels. Apart for
physical separation, which is efficient in petroleum wastewater, several innovations in technical
techniques for advanced treatment and pre-treatment have occurred in recent years.
