The Filtration Pilot Plant mainly consists of a sand filter and an activated carbon filter; filtered water is collected into a tank of stainless steel from which samples for proper laboratory analyses can be extracted. An in-line turbidimeter enables to measurement of the turbidity of water flowing in and out of filters. Process control, data acquisition, and supervision are automatically carried out by a microprocessor controller and by a specific control and supervision software (only for automatic plants) that enables the remote control of various operational parameters.
