Oils and grease removal treatment in wastewater project

Oils and grease removal treatment in wastewater project

Effective oil and grease removal depends on the characteristics of the oil in terms of suspension state and droplet size, which in turn affects the choice of separator technology. Oils in industrial wastewater may be free light oils, heavy oils (which tend to sink easily), and emulsified oils (often referred to as soluble oils). Emulsified or soluble oils often need to be "cracked" to release the oil from its emulsion. In most cases this is achieved by lowering the pH of the water matrix. Most separator technologies will have an optimal range of droplet sizes that can be effectively handled. Oil and water can be analyzed using a video particle analyzer to determine droplet size. Each separator technology has its own performance curve outlining optimum performance based on droplet size. The most common separators are gravity tanks or pits, API oil-water separators or plate packs, chemical processing via DAF, centrifuges, media filters, and hydrocyclones. Brine treatment technologies may include: membrane filtration processes, such as reverse osmosis; ion exchange processes, such as electrodialysis or weak acid cation exchange; or evaporation processes, such as brine concentrators and crystallizers using mechanical vapour recompression and steam. Reverse osmosis may not be suitable for brine treatment due to possible scaling from hardness salts or organic contaminants, or damage to reverse osmosis membranes by hydrocarbons.
