Examples include meat and by-product processors and small community effluent treatment plants where end-of-pipe clarification can deliver energy savings greater than 95%. Reclamation applications requiring the use of alternate physico-chemical processes (such as precipitation, adsorption, oxidation or disinfection) also directly benefit from Baleen micro-screening. Examples include metal precipitate separation and ion- exchange resin recovery to deliver plant footprint-savings greater than 95%. A Best-Available-Technology approach to water reclamation may thus be defined quite simply by a ‘One-to-Four-Step Method’ outlined as follows: 1) visible to sub-visible matter recovery by first-stage Baleen micro- screening (to outperform any clarifier); and/or 2) physico-chemical treatment; to facilitate 3) sub-visible to colloidal matter separation by secondary Baleen micro- screening (to outperform any flotation plant); followed by 4) oxidation/disinfection of residual constituency. However, Baleen need not be considered an alternative approach to water treatment or resource recovery; many clientele simply benefit from increased plant efficiencies as a direct consequence of Baleen’s enhanced separation capability. Capital payback on installation is often less than two years within food and beverage applications, one year for municipal applications and just months in minerals processing. Baleen filtration systems may be applied to applications as small as 20kL per day and are equally scalable for the very large well beyond 20ML per day. Repeat clientele include Inghams, Tyson Foods, JB Swift, Nestle, Chevron and Anglo American. Repeat applications include washwater recycle, pond replacement, DAFF enhancement, backwash reclamation, clarifier polishing, resource recovery, sludge thickening, water re-use and membrane protection.

BluSeal AKS is now the market leader in this category. While distributor Bluey Technologies has taken a cautious approach to introducing this lining, there have been some impressive applications to date. Since their introduction, cast-in HDPE liners have been used on projects including the Adelaide Desalination Plant, Werribee Aqueduct and Eastern Treatment Plant in Melbourne. The primary concern for Bluey Technologies, according to Bluey’s Managing Director Daniel Bosco, “has been to ensure that all applications are supported by systematic installer training regimes and site quality processes to ensure a durable and cost-effective outcome for every project. Bluey Technologies supports each typical application with a warranty and a 100-year design-life statement of durability. We are determined to ensure that every application, once complete, will remain in place for life.” Bluey Technologies insists that AKS be installed only by trained and approved DELIVERING PUMPING SOLUTIONS Call us to discuss your applications: Melbourne 03 9793 9999 Sydney 02 9671 3666 Brisbane 07 3200 6488 Email: email@example.com Web: www.brownbros.com.au HYDROVAR, the modern variable speed pump drive is taking pumping to a new level of flexibility and efficiency.
