Tesca Filtration Pilot Plant 32483 mainly consists of a sand fi lter 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 turbidimeter enables to measure the turbidity of water fl owing 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 plant) that enables the remote control of various operational parameters.
