SPIRAC was contracted to upgrade the Inlet Works Area for this project to allow for future population growth in the area.
SPIRAC supplied and commissioned FINEGUARDTM a traveling fine screen and SPIROWASH® a screen-specific washpactor. The Inlet Works upgrade improved the screening capture at the head of the WWTP inlet works. SPIRAC supplied and commissioned FINEGUARDTM a traveling fine screen to replace the an undersized screen. SPIRAC also provided a SPIROWASH® unit, a screen-specific washpactor to dewater screenings and improve organics retention. FINEGUARDTM is able to handle a flow rate of 250 L/s. The screen is equipped with 5 mm perforated panels that can achieve a Screen Capture Ratio (SCR) of 79 %.
The SPIROWASH volume reduction can range from 50 to 85% and moisture reduction can range from 35 to 50%. The DS content of the final screenings are approx. 35 to 45% DS.
