A polydisc filter of a disco strainer type that already
exists in the factory was used to remove the remaining flocs.
The maximum total suspended solid in the filtered water
was 50 mg/l. This water is used for the processes of screen
showers, cleaning hoses, vacuum pumps sealing, dilution
and flushing water. The excess clean water was discharged
into the public sewage network. Consequently, the fresh water
consumption in the factory was used only in felt showers, wire
showers and trimming nozzles with a maximum consumption
of 400 m3
/d as shown in (Table 2). This solution saved L.E.
270,000/year with a payback period of 3 days.
