NOVEMBER 2014 WATER 85 Water Business resolves the practical issues -- all vital parameters are controlled with little maintenance and consistent results are achieved long term. For more information on FiltaOdor please email: firstname.lastname@example.org ONSITE WATER BIOMASS TESTING Poor control of bio lms creates a range of problems in various industries such as drinking water, wastewater and water for power generation. Many of the problems occur due to corrosion, odours, clogged valves and lters, and reduced cooling ef ciencies. Control of bio lms with biocides is dif cult and expensive. Underuse can lead to the problems caused by bio lm formation, and overuse can be costly and create other problems with corrosion or excessive wastewater generation. To achieve optimum results you will need to sample and test to determine when to take action. However, traditional methods can take days to return results. Now, the portable Biomass Field Tester from Promicol can provide a solution to your problems of bio lm control in minutes, without the need for laboratory facilities. Based on ATP Bioluminescence, the system can provide a rapid indication of Total and Viable Biomass, which indicates the risk of bio lm formation. The Field Tester includes a luminometer, shaker and power supply, and ts into a compact, easily transportable case. Extra kits to replace reagents and plastic-ware are also available. Biocide usage can now be optimised for better control of bio lms, on-site and in real-time.

Wind causes variable evaporation rates that auto irrigation cannot accommodate. Media is subject to weed and vermin infestation. The enclosed vessel facilitates a more consistent temperature average. Optimal moisture content is maintained. There is minimal seasonal impact. There is no weed or vermin infestation. Media Interface SOIL BED FILTAODOR If media is in direct contact with the granular bedding of the diffuser pipes, material migrates through and blocks the pipes. If a separation layer such as geofabric is used to prevent this, the geofabric itself restricts air ow. Incorporates a cored deck separating the media from the plenum. The deck has a speci c aperture size and number to ensure there is no restriction or increase in air ow velocity. The media is placed directly on the deck with no need for any other separation layer. The media does not break down and allow migration of material through the deck. Venting SOIL BED FILTAODOR Emission capacity of the slotted diffuser pipes needs to be tuned to match the inlet ducting capacity. It also needs to be tuned for even distribution across the diffuser pipe layout. Inlet ducting size is designed for optimum air ow, open plenum allows even distribution, exhaust is via a correctly sized exhaust vent.
