Catabolic design [ edit ] Just as a septic tank is sized to support a community of anaerobic organisms capable of liquefying anticipated amounts of putrescible materials in wastewater, a drain field should be sized to support a community of aerobic soil microorganisms capable of decomposing the anaerobic septic tank's effluent into aerobic water.
Cleanroom from outside Entrance to a cleanroom with no air shower Cleanroom for microelectronics manufacturing with fan filter units installed in the ceiling grid Cleanroom cabin for precision measuring tools Typical cleanroom head garment. A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne ...
When properly incorporated into cleanroom design, air showers provide an ISO-classified transition vestibule to ensure the cleanliness of the classified cleanroom. Air showers are typically placed between a gowning area and cleanroom; after workers don appropriate garb and personal protective equipment , they enter the shower so that the ...
A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater flows for basic sewage treatment. [2] Settling and anaerobic digestion processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). [2]
A simple design is a manhole that allows a sanitary worker to open and close a value from the ground level to perform water filling and flushing operations. Water source for flushing manholes can come from potable water, tidal water, or water from clarifiers of sewage treatment plants [ 1 ] [ 29 ]
Clean-room design (also known as the Chinese wall technique) is the method of copying a design by reverse engineering and then recreating it without infringing any of the copyrights associated with the original design. Clean-room design is useful as a defense against copyright infringement because it relies on independent creation. However ...
Cleanroom suitability describes the suitability of a machine, operating utility, material, etc. for use in a cleanroom, where air cleanliness and other parameters are controlled by way of technical regulations in accordance with ISO 14644.
Note that layout for a production system reflects a conceived organisation of resources to achieve a certain goal, besides satisfying certain space constraints. In manufacturing engineering , process layout is a design for the floor plan of a plant which aims to improve efficiency by arranging equipment according to its function. [ 1 ]
