backwashing under pressure Explanation: Backwashing (water treatment) In terms of water treatment, including water purification and sewage treatment, backwashing refers to pumping water backwards through the filters media, sometimes including intermittent use of compressed air during the process. Backwashing is a form of preventive maintenance so that the filter media can be reused. In water treatment plants, backwashing can be an automated process that is run by local programmable logic controllers (PLCs). The backwash cycle is triggered after a set time interval, when the filter effluent turbidity is greater than a treatment guideline or when the differential pressure (head loss) across the filter exceeds a set value. https://en.wikipedia.org/wiki/Backwashing_(water_treatment) The lter media can be cleaned by washing it down, or by backwashing under pressure, with a supply of clean water. http://waterwiki.net/images/3/30/Water_Aid_technology_notes_... -------------------------------------------------- Note added at 13 mins (2018-01-18 17:26:11 GMT) -------------------------------------------------- Note: I really should downgrade that CR to a 3 as I found some references, but not very many. There might be a more commonly-used term for this in English. |
