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 FINEGUARD^TM, a travelling fine screen and SPIROWASH^® a screen-specific washpactor. 

The WWTP Inlet Works upgrade improved the screening capture at the head of the WWTP inlet works. SPIRAC supplied and commissioned  FINEGUARD^TM a travelling fine screen to replace the undersized step screen. SPIRAC also provided a SPIROWASH^® unit, a screen-specific washpactor to dewater screenings and improve organics retention. FINEGUARD^TM can handle a flow rate of 250 L/s. The screen is equipped with 5mm 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 is approx. 35 to 45% DS
