Gone are the days when all groundwater was simply pumped, chlorinated and distributed, and all surface water treatment systems were designed according to the classic "pre-chlorination, coagulation, flocculation, settling, deep filtration, disinfection" scheme.

This article describes most of these so-called "conventional" treatment processes for ground and surface water, along with a number of tests essential to their optimization.

However, conventional treatments...
