algae control in drinking water plants

by LG Sonic     based in Zoetermeer, NETHERLANDS

By controlling algae, cyanobacteria and fouling LG Sonic can efficiently reduce taste and odor problems in a treatment plant. The performance of a drinking water treatment plant is consistent with the amount ol contamination in the water. Growth of algae and other fouling in and before a treatment plant can cause various problems within the process. In general, these issues are related with taste or odor of the water. Growth of algae, cyanobacteria and bacteria within the basins of the plant itself, increase the demand of chemicals or filtration and in turn creating problems with THM (trihalomethane) formation. Other common issues are growth of toxin and geosmin producing cyanobacteria (blue-green algae) within the intake reservoir or dam. These molecules give the water an unpleasant `earthy ` taste.

Dust monitoring and Sand Storm Monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

The frequency and intensity of dust and sand storms in many parts of the world are steadily increasing due to droughts and climate change. The severity of such storms is anticipated to increase over the coming years. These dust storms may last hours or days and cause huge damage and imposed a heavy toll on society with its physical effects, such as visibility reduction, heavy winds, red sky, hailstone and severe lightning. Such Dust storms, have a negative impact on human health, and industrial products and activities. They reduce visibility, layer on skin and cloths, infiltrate buildings and find their way into food and drinking water leaving a permanent sandy feeling in your mouth. Traditional dust monitoring instruments whether they be purely filter based gravimetric samplers or continuous monitors utilising Tapered Element Oscillating Microbalance (TEOM) or Beta Attenuation (BAM) simply are unable to cope with the high dust loads created by these storms. The filters on these instruments are quickly clogged and no further measurements are possible until a service technician visits to replace filters and filter tapes. In dust storm events this is impossible. Therefore, over the past few years a need for alternate technology which are non filter based, can cope with extremely high dust loads, require minimal maintenance and can operate off solar power has been employed in regions such as the Gobi Desert of China for the continuous monitoring of dust storm events. These instruments have demonstrated that an instrument can measure dust storm events with maintenance performed only once every 12 months. That it is possible to communicate remotely and that these systems can not only provide an early warning for dust events but have the accuracy and sensitivity to be an extremely useful tool in gauging hourly changes of visibility. Infact such instruments have been utilised by a number of EPAs around the world, including all Australian EPAs for the purpose of measuring ambient visibility as well as providing an accurate indication of rising dust events.

WEDA Underwater cleaning robots in lagoons and large fountains

by Weda AB     based in Södertälje, SWEDEN

The new Weda YT-5000 with a five (5) meter wide suction nozzler speeds up the cleaning process considerably. Estimated cleaning speed is up to 3000 sq. meters/hour. The cleaner removes efficiently bottom sedimentation (sand, algae etc.) from the bottom surface and pumps it to a selected discharge point (filter, waste etc).
