RESUMO:

Water treatment plant are designed according to the water’s quality on source, which directly sets up the treatment technology to be used and consequently influences costs of operation and maintenance. The optimization of the processes in WTP is primordial for reducing costs and improving the quality of treated water. The filtration process is considered by the literature as polishing step, responsible for the removal of suspended particles, and removal of protozoan cysts and oocysts. During backwashing it may consume between 3% and 10% of the volume produced in the WTP, and it’s relevant in the final result of water production. The general objective of this paper was to evaluate modifications in production of water on WTP in real scale through changes in filtration’s careers. Physical and chemical characterization of backwashing’s water of the filters, raw water, treated water and recirculation’s water, as well as the monitoring of the pressure loss of the filters in different filter run. The results showed that: the increase of filter run increased the amount of solids in backwash water; the growth of the loss behaves as a first-degree function; You can change filter run from 24 hours to 40 hours under normal conditions at WTP Extremoz.
