EN 12255 - Wastewater treatment plants refers to a set of European standards which specify the general requirements for structures and equipment that relate to wastewater treatment plants for a total population of more than 50 PT (population total). This standard, however, does not include the design of a treatment processes itself. [1]

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.
By 1948, the state declared San Jose to be in violation of state water pollution regulations, risking a moratorium on building permits. [4] In 1950, San Jose voters finally passed bonds to construct a new wastewater treatment facility. [4] In 1954, the city purchased land near Alviso for a wastewater treatment plant. The plant began operations ...
The SHARON (Single reactor system for High activity Ammonium Removal Over Nitrite) wastewater treatment process is a combination of two already used nitrogen removing reactions. One process utilizes fast growing nitrifiers utilizing nitrification of ammonia to nitrite and Anammox which is the denitrification of nitrite to atmospheric nitrogen ...
In the case of a plant with a single tank, a retrievable system is desirable, in order to avoid stopping operation of the plant when maintenance is required on the aeration system. Fixed systems, on the other hand, are typically less costly, and often more efficient because it is easier to make full use of the floor.
