VEOLIA WA­TER TECH­NOLO­GIES Aus­tralia has been con­tracted for the de­sign, sup­ply, and com­mis­sion­ing of 20 Hy­drotech Drum­fil­ters for me­chan­i­cal pri­mary treat­ment at two of Syd­ney Wa­ter’s treat­ment plants; St Mary’s Wa­ter Re­cy­cling Plant and Quak­ers Hill Wa­ter Re­cy­cling Plant. The up­grade is part of Syd­ney Wa­ter’s Lower South Creek Treat­ment Pro­gram.

The re­source man­age­ment com­pany says with a move to­wards en­ergy re­cov­ery and en­ergy ef­fi­ciency in waste­water plant de­sign around the world, the first step of pri­mary sep­a­ra­tion has be­come very im­por­tant for two rea­sons – a higher TSS re­moval in the pri­mary step re­duces the load on the sec­ondary treat­ment process (re­duc­ing power re­quire­ments and op­er­at­ing costs) and in­creased amounts of pri­mary sludge en­ter­ing the down­stream sludge treat­ment or bio­gas re­cov­ery stages (such as di­ges­tion and/or ther­mal hy­drol­y­sis) will in­crease en­ergy re­cov­ery.

This project con­tin­ues the ‘ex­cel­lent’ ex­pe­ri­ence Veolia has gained over the last 10 years in util­is­ing Hy­drotech Drum­fil­ters for pri­mary sep­a­ra­tion. The small foot­print tech­nol­ogy al­lows ex­cel­lent TSS re­moval (up to 80 per­cent for this project de­pend­ing on in­flu­ent waste­water qual­ity) com­bined with the abil­ity to cope with highly fluc­tu­at­ing flows in terms of both qual­ity and ca­pac­ity. The high­qual­ity stain­less steel Hy­drotech Fil­ters com­bined with in­no­va­tive ro­bust PE fil­ter pan­els guar­an­tees an ef­fi­cient, low main­te­nance, ro­bust, and flex­i­ble pri­mary sep­a­ra­tion step.

Syd­ney Wa­ter is Aus­tralia’s largest wa­ter and waste­water ser­vice provider. Ev­ery day, it sup­plies wa­ter, waste­water, re­cy­cled wa­ter, and some stormwa­ter ser­vices to more than five mil­lion peo­ple in Syd­ney, the Illawarra and the Blue Moun­tains re­gions.
