Hybrid treatment plants: maintaining production
It is known that large and complex water treatment plants are most efficient when production levels are maintained at or near the design capacity over the long term. As production rates rise and fall dramatically, it is required to change operations and startup/shutdown major pieces of equipment, costing the plant more money to operate and maintain. One of the major problems with treating stormwater is that the water rushes through during storm events then virtually disappears at other times, usually at times that are unpredictable. Regulating these flows using storage is most likely uneconomical because of the high cost to build huge storage facilities. Another problem with treating stormwater for reuse is that the water quality of the stormwater is possibly different than the traditional water supply and so a totally different treatment process might be necessary. What if a treatment plant was able to quickly change the type of treatment process but maintain overall producti...
