Bis(2-ethylhexyl) phthalate (di-2-ethylhexyl phthalate, diethylhexyl phthalate, diisooctyl phthalate, DEHP; incorrectly — dioctyl phthalate, DIOP) is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. DEHP is the most common member of the class of phthalates, which are used as plasticizers.
One common process in wastewater treatment is phase separation, such as sedimentation. Biological and chemical processes such as oxidation are another example. Polishing is also an example. The main by-product from wastewater treatment plants is a type of sludge that is usually treated in the same or another wastewater treatment plant. [2]:
This includes Bis(2-ethylhexyl) phthalate (DEHP or DOP), which has long been the most widely used phthalate, with commercial production dating back to the 1930s. [ 16 ] [ 17 ] In the EU, the use of DEHP is restricted under REACH and it can only be used in specific cases if an authorisation has been granted; similar restrictions exist in many ...
TBPH is the brominated analogue of bis(2-ethylhexyl) phthalate (DEHP). Much like TBPH, DEHP has been widely used as a plasticizer , however unlike TBPH, it is currently a restricted substance due to its endocrine disrupting properties and reproductive toxicity . [ 6 ]
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.

Bis(2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer , being the diester of terephthalic acid and the branched-chain 2-ethylhexanol , which is often generically referred to as octyl.
The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa. It is one of several biological wastewater treatment alternatives in secondary treatment , which deals with the removal of biodegradable organic ...
