In some applications, air and water streams are simultaneously pushed upwards through the granular media followed by a rinse water wash. [3]: 213–4 Backwashing continues for a fixed time, or until the turbidity of the backwash water is below an established value. At the end of the backwash cycle, the upward flow of water is terminated and the ...
A plate strainer is the simplest, in which water flows through a perforated plate. Often the plate is corrugated shape to increase surface area. A basket strainer is a design where the strainer is shaped like a basket and usually installed in a vertical system. The basket strainer is easier to clean, since debris is captured in the basket.
A colander (or cullender) is a kitchen utensil perforated with holes used to strain foods such as pasta or to rinse vegetables. [1] The perforations of the colander allow liquid to drain through while retaining the solids inside. It is sometimes called a pasta strainer. A sieve, with much finer mesh, is also used for straining.
In addition, CIP systems can be built into the borehole headworks to permit the injection of cleaning solutions (such as sodium hypochlorite or other sanitizers) and the subsequent recirculation of the mix of these chemicals and the groundwater. This process cleans the borehole interior and equipment without any invasive maintenance being required.
Duplex strainer [1] or twin basket strainer is a type of filter built into a fuel, oil or water piping system and it is used to remove large particles of dirt and debris. The duplex features a design that makes strainer basket servicing a no-hassle operation. The duplex strainer system usually consists of two separate strainer baskets housings.
Salad spinners are usually made from plastic and include an outer bowl with an inner removable colander or strainer basket. A cover, which fits around the outside bowl, contains a spinning mechanism that when initiated causes the inside strainer to rotate rapidly. The water is driven through the slits in the basket into the outer bowl.
This filter is an open sand filter system used for water treatment in low budget environments. It can suit a variety of pressure-controlled backwashing. This filter is an automatic gravity filter that uses different pressures and backwashes the system with an injector. The system has no controls. The filters have no moving parts and no pumps.
A dishwasher containing clean dishes. A dishwasher is a machine that is used to clean dishware, cookware, and cutlery automatically. Unlike manual dishwashing, which relies on physical scrubbing to remove soiling, the mechanical dishwasher cleans by spraying hot water, typically between 45 and 75 °C (110 and 170 °F), at the dishes, with lower temperatures of water used for delicate items.
