Primary Definition: Anaerobic wastewater treatment is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen[1]. Secondary Definition: Anaerobic digestion is used as part of the process to treat biodegradable waste and sewage sludge. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill […]

Primary Definition: Biological treatment processes that occur in the presence of oxygen [1]. Secondary Definition: The aerobic process includes Suspended growth, Attached growth and Hibrid suspended and attached growth processes [1]. 2. Background    Technology History: – Aerated wastewater treatment has been used the 1800s in the form of media filters, suspended grow aerated treatment is […]

Primary Definition: Nanofiltration separates matters bigger than nanometer sized membrane pores and treated solution passing out through membrane pores [1]. Secondary Definition: Nanofiltration is a pressure-driven membrane filtration process in order to treat matters with 200-1000 g/mol sized molecular weight including disinfection byproducts, and to soften water [2]. 2. Background         Technology History: – Nanofiltration, the […]

Primary Definition: Greywater system is a system where greywater is reused as water source for non-drinking water level usage (e.g. garden watering, flushing water) [1]. Secondary Definition: Greywater system may or may not use wastewater treatment. The aim is to reduce the need of clean water needed for application like garden watering and flushing [1]. […]

Primary Definition: Desalination is the process of removing dissolved salts and minerals from saline water. The main goal is to produce a fresh water supply for drinking, irrigation or industrial usage (1). Secondary Definition: Desalination involves the use of heat, osmosis or electro dialysis to produce a large amount of fresh water and small amounts of […]
