Biological treatment of precious metal refinery wastewater
Biological treatment of precious metal refinery wastewater: A review
Refinery wastewater biological treatment: A short review. reaction mechanism of this process was discussed by comparing the results of variant reaction systems with different metal particles
Biological treatment of precious metal refinery wastewater
A combination of biological treatment and biosorption can be a viable technology for the treatment of complex and potentially toxic wastewaters. Improved treated wastewater quality can allow for reuse in refinery processes which could lead to significant cost reduction and prove to be environmentally beneficial.

Biological Treatment of Petroleum Wastewater: A Review
effective solution for the wastewater treatment in petroleum industries and industries. Kenari et.al. carried out in depth investigation on the nitrogen content of a petroleum refinery wastewater[23]. They also studied biological treatment of this wastewater for nitrogen removal. They performed nitrification and denitrification process.
However, this biological process could be inhibited if this process configuration was applied to real metal refinery wastewater without pre-treatment, such as neutralisation and dilution, due to the extreme pH conditions, high concentrations of nitrogen compounds (e.g., >1700 mg/l NO 3--N was measured in one wastewater), high COD (>15,000 mg/l

Integrated Bio-Reactor Biological Sewage Treatment System (IBR) Dissolved Air Floatation is widely used for separating solids, fats, oil, and grease from a waste stream. In the process, pressurized water is saturated with dissolved air and is discharged into a flotation vessel. Read More; High-concentration food wastewater treatment by an
Forward osmosis (FO) is a membrane technology that uses the osmotic pressure difference to treat two fluids at a time giving the opportunity for an energy-efficient water and wastewater treatment. Various applications are possible; one of them is the application in industrial water management.

- What is polyacrylamide (PAM)?
- Polyacrylamide (PAM) is a polymer formed from acrylamide subunits, it is long-chain polymer designed to attract either positively charged particles (organic materials, such as carbon or human waste) or negatively charged particles (inert materials, such as sand or clay).
- Which Polyacrylamides are used as coagulants?
- Alum and PACl were used as coagulants and very high molecular weight cationic polyacrylamide (C-PAM), Organpol 5415, with low charge density and high molecular weight anionic polyacrylamide (A-PAM), Chemfloc 430A, with high charge density were used as flocculants.
- Does polymer polyacrylamide interact with tin tetrachloride?
- The main aim of this study is to assess how well the polymer polyacrylamide (PAM) could interact as a coagulant, coagulant aid or flocculant with the tetravalent metal coagulant tin tetrachloride (SnCl) in the removal of contaminants from leachate.
- Is polyacrylamide a good flocculant?
- Polyacrylamide (PAM, − CH 2 CHCONH 2−) is a flocculant that is commonly used in the treatment of drinking water. By building bridges between destabilised particles, PAM could create micron-sized aggregates with good settling qualities. Cationic, nonionic and anionic PAM materials have been investigated for their flocculation capabilities.
