Membrane bioreactor. Membrane bioreactors are combinations of membrane processes like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge process. These technologies are now widely used for municipal and industrial wastewater treatment. [ 1] The two basic membrane bioreactor configurations are ...
Moving bed biofilm reactor. Moving bed biofilm reactor ( MBBR) is a type of wastewater treatment process that was first invented by Professor Hallvard Ødegaard at Norwegian University of Science and Technology in the late 1980s. [ 1] The process takes place in an aeration tank with plastic carriers that a biofilm can grow on.
A rotating biological contactor is a type of secondary (biological) treatment process. It consists of a series of closely spaced, parallel discs mounted on a rotating shaft which is supported just above the surface of the wastewater. Microorganisms grow on the surface of the discs where biological degradation of the wastewater pollutants takes ...
In waste water treatment, membrane technology is becoming increasingly important. Ultra / microfiltration can be very effective in removing colloids and macromolecules from wastewater. This is needed if wastewater is discharged into sensitive waters especially those designated for contact water sports and recreation.
Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [ 1]: 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.
The New York City Department of Environmental Protection ( DEP) is the department of the government of New York City [ 2] that manages the city's water supply and works to reduce air, noise, and hazardous materials pollution. Under a 1.3 billion dollar budget, it provides more than 1.1 billion US gallons (4,200,000 m 3) of water each day to ...
The Bureau of Wastewater Treatment operates 14 water pollution control plants treating an average of 1.5 billion US gal (5.7 million m 3) of wastewater a day; 95 wastewater pump stations; eight dewatering facilities; 490 sewer regulators; and 7,000 miles (11,000 km) of intercepting sewers.
Jackson told the New York Times that “the dressing bulked up a bit because you need a bit of absorbent. You don’t want to be walking around with bloody gauze on his ear.”. Donald Trump ...
