摘要

With the impacts of global warming on the international agenda, efficient energy utilisation isrnat the forefront of all business decisions. Historically the embodied energy in raw water thatrnhas been lifted to a water treatment plant (WTP) has been well used by conventionalrntechnologies minimising costs and energy inputs. Indeed, there remains a high degree ofrnfocus on obtaining the optimum hydraulic profile during the design phase of any new WTP orrnWTP upgrade to minimise pumping costs and the associated environmental and financialrnimpacts. This is somewhat in contrast to advanced water treatment facilities which utilisernmicro and ultrafiltration membranes. In a majority of cases re-pumping is seen as inevitablernand the designers are released from the shackles of available head and hydraulic profiles.rnThe result is that membrane technologies suffer in financial and environmental assessmentsrnwhen they are tested against conventional treatment technologies due to their inability tornutilise the embodied energy of the raw water.rnIt is however possible to utilise the embodied energy of raw water for pressurised andrnsubmerged membranes to reduce capital and operating costs. An example of this is the 100rnMLD submerged membrane Bray Park WTP, in Murwillumbah, New South Wales, Australia.rnDuring the design phase an opportunity was identified within the constraints of the existingrnraw water pumps, clear water tank and site location to utilise siphon. An analysis wasrnperformed to determine the true available head and the ultimate benefit in utilising a siphonrnto pull water through the submerged membranes in place of, or in conjunction with pumping.rnAnalysis indicated that, whilst sensitive to power costs, the financial payback period for thernmodifications required to undertake siphon operation was in the order of 5 to 7 years. Whenrnadditional non-cost factors were considered, as well as risks associated with climbing powerrncosts, siphon was incorporated into the design.rnThis paper considers the initial technical assessment of siphon at Bray Park WTP againstrnthe reality of incorporating the required modifications into the design, the financial,rnenvironmental and economic benefits of utilising siphon and the performance of siphon overrnthe first six months of plant operation.
