Mechanical Operation Lab.

This filtration plant mainly consists of a sand filter and of 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 turbid meter enables to measure 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 that enables the remote control of various operational Parameters.

The activated sludge pilot plant consists of an oxidation reactor, of a settler and of a final chlorination tank, according to the traditional diagram of single-stage sewage treatment process. Biomass is oxidized in a reactor with agitator by the air blown by a compressor. The processed liquid is sent to the settler through an overflow. The sludge settling on settler bottom are recycled by are circulation pump into the oxidation tank. The water flowing out of the settler is chlorinated and conveyed to a drain. Process control, data acquisition and supervision are automatically carried out by a microprocessor controller and by a specific control and supervision software that enables the remote control of various operational parameters.
