AUGUST 2013 WATER 113 Water Business WATER BUSINESS NECESSITY THE MOTHER OF INNOVATION Waterform Technologies is demonstrating the bene ts of technology leadership, with new practices that can even challenge some text book 'rules' in cost effectively advancing the use of recycling and reusing water from many challenging sources. While currently undertaking specialist potable water supplementation projects with some of the most rigorous treatment steps and strictest controls being implemented, it is the individual technologies that are part of the Waterform product portfolio that are so impressive. nextSand is one innovative product that should be part of any project where media ltration is needed -- as can be seen in a recent installation at Batemans Bay in NSW. With a Stage One peak ow of 160L/sec, this tertiary water recycling plant consisting of nextSand, UV and chlorine treats water for irrigating community sporting facilities. The advantage of nextSand, a single layer media, is its ltration velocities, which are 25m3/m2/HR -- 35m3/m2/HR. This means the pressure vessels or gravity tanks holding the media can be drastically downsized. At Batemans Bay, this resulted in the multimedia design concrete slab size of 18.0m x 20.0m being reduced to 13.0m x 14.0m. This saving in civil works, along with reduced sized ltration equipment, resulted in a signi cant equipment CAPEX reduction of approximately 55% from the budgeted ~1.5 Million. nextSand is delivering excellent ltration performance, with conformance to the <2NTU ltrate 95%tile target (typical 0.8-1.3NTU), despite in uent turbidities ranging from 10 -- 70NTU. Filtering to 3-5miron, and with a basic composition of porous opal (opaline silica), nextSand is very hard and resistant to attrition. Waterform's dedication to innovative products is also seen in the UV Disinfection systems installed at Batemans Bay. These powerful UV Strike LPHO reactors use fewer lamps than the industry average with a high-wattage lamp, but more importantly contain a key advancement in UV Technology -- 'soft starting' of the LPHO lamps, which prevents electrode degradation within the lamp, and has resulted in the German- made UV Strike units having limitations removed on switchings per 24 hours, and a site-proven life span of over 21,000 hours. The Barrier Ultra ltration system incorporating the inge UF membrane is another example of innovation. The system has a unique capillary structure of 7-into-1, known as the Multibore. This gives the inge UF very high structural strength and cleanability. With bre breaks a thing of the past, and no air scour required for cleaning the membrane, ef ciencies are maximised. This structural strength allows a high ux backwash of 230l/m2/HR, where the 'annular gap' backwash ensures every cm2 of membrane surface area receives equal cleaning velocity, meaning chemical requirements are minimised and air scour is deleted. The inge UF module is also incorporated into the innovative T-Rack pipe manifolding system where the top and bottom distribution pipework is contained within the width of the membrane module/s, saving valuable space. SpongePak is another innovative product from Waterform to consider, used as a primary step for removal of hydrocarbons (fuel, oil and grease) from water. In today's economic climate it is crucial to maximise return on complex water infrastructure investment with innovative technologies, and Waterform Technologies is demonstrating the bene ts of this approach in practice.

OZONE PIPELINE DISINFECTION SYSTEM Under Water Management Plans, water utilities in NSW require many newly installed residential pipelines to be disinfected prior to being placed into service. For these pipelines the usual method is to rst ush and then super-chlorinate before biological testing to con rm that the process has been effective. In NSW, this is usually carried out by the water utility itself. The use of concentrated chlorine in this process leads to a number of hazards: • Storage of concentrated chlorine liquid presents problems; • Workers are exposed to the fumes and risk skin contact with chlorine; Whether it's for drinking, irrigation or industry, Australia's climate and reliance on water has produced some of the world's most innovative suppliers of water products and services. Now there's an online tool that brings all these suppliers together in one central location. ICN's Water Directory is a pivotal connection point for project and procurement managers looking for the best water industry suppliers in our region. This comprehensive directory has a powerful search function that allows you to fnd suppliers with capabilities that exactly match your needs. Combine this with the experience and knowledge of ICN's consultants and you can be sure you'll never miss an opportunity to fnd the perfect partner.
