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 the submerged ...
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.
Data for water and sanitation based on the Survey of Living Conditions (2002). In urban areas, where 52% of Jamaica’s population lives, access to improved water supply is 98% access to improved sanitation is 91%. Only 31% of the urban population is connected to sewers. In rural areas access stands at 88% for improved water supply and 69% for ...
This page consists of a list of wastewater treatment technologies : Activated sludge model. Activated sludge systems. Adsorption/Bio-oxidation process. Advanced oxidation process. Aerated lagoon. Aerobic granular reactor. Aerobic granular sludge technology. Aerobic granulation.
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.
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 ...
