Water Technology - Jan 2012

FEATURE potable water per year previously used for this same purpose In Dubai a reverse osmosis desalination plant takes water from the Arabian Gulf and turns seawater into water clean enough for municipal use including drinking water The project is in part a result of high performance standards WATER TESTING INSTRUMENTS New products from the company that brought you the TDS 3 CONDUCTIVITY pH TDS ORP Taking a chance on an unaudited media buy www watertechonline com 11 TEMPERATURE VOLUME TIME www hmdigital com Circle 226 AP 1 AP 2 Modern TDS Conductivity Meters PH 80 Economical pH Tester FM 2 Filter Monitor 5 Stage Inline Timer Volumizer could lead you nowhere Advertising in Water Technology is a smart choice Water Technology is one of three magazines in the water treatment industry whose circulation statements are reviewed and verifi ed by outside auditors Make the smart choice Your marketing budget is one of your most important investments Spend it wisely Buy space only in audited magazines BPA International audits Water Technologys circulation along with 2500 other publications in more than 20 countries miles irrigating 175000 acres of land to help feed Indias growing population and economy In Doha Qatar treated wastewater is soon to be reused for agricultural irrigation and landscaping This water scarce country with a population of over 800000 will save millions of gallons of cover water usage as well With this type of system all of the water is re circulated and there is fresh water intake only to cover for water lost through evaporation This fresh water could be initially used for drinking and cooking The technology is available but is not implemented from a system point of view in large part due to investment costs There is a general concern about rising investment costs and to bring down costs we need to increase capacity However this will create even more challenges with respect to running facilities efficiently We must search for ways to bend the normal linear relationship between investment cost and process capacity while minimizing process variations that might cause hiccups in the system One way to do this is to look for decentralized solutions in both water supply and wastewater treatment such as point of supply treatment and quality testing to reach drinking and cooking standard Bringing the final treatment of water closer to the end user could potentially allow for more biodegradable and sustainable treatment solutions Wastes through infrastructure It is obvious that there is a huge untapped supply capacity being wasted throughout our infrastructure There are many interesting opportunities to re engineer water cycles for buildings blocks and cities However risks need to be eliminated through controlled scale up procedures We have opportunities to create industrial approaches through the piloting of new technology in demo environments where there are no stringent operational conditions Without such an opportunity we will continue to build our future entirely on existing infrastructure without any major changes in sustainability The following are some examples of technological solutions to how industry is helping to address community water needs from India and Australia to Qatar and Dubai In India large water transport pumps are helping turn arid land into farmland In one of the largest irrigation projects in the world these large vertical pumps are transporting water 155
