Disinfection is the process of destroying pathogenic micro-organisms by physical means. There are a number of chemicals and processes that will disinfect wastewater. Disinfection is usually the final stage in the wastewater treatment process in order to limit the effects of organic material, suspended solids, and other contaminants.
wastewater treatment required prior to food crop application ordinarily is established by health and environmental quality considerations. Disinfection and suspended solids removal are the processes most frequently used to further improve conventional wastewater treatment plant effluents for use on crops.

For heavy fouling conditions (found in some industrial cooling towers and boilers, waste treatment plants, and some processes, such as metal treatment baths) an electrodeless (toroidal) conductivity probe (Figure 36-1) must be used. The toroidal probe uses inductance to sense conductivity changes in a process solution.
The first stages of waste water ( sewage ) treatment are commonly physical and aimed to remove larger suspended solids from waste water, primarily using gravity to allow larger (heavy) particles to settle while allowing the remaining liquid to continue through the plant. Primary waste water treatment uses simple mechanical physical processes to remove nearly half of the solid contaminants ...
