  • Reliable oxygen levels in trout farms with LDO

    An adequate level of oxygen must be maintained in the water of fish farms. If the level is too low, fish production suffers. Stocking density, feed intake and resistance to disease are just three of the key variables that significantly affect profitability and are directly dependent on the oxygen concentration. Kirsten and Alexander Tautenhahn have run a trout farm in Germany, since 1991. Oxygen ...


  • Effective Removal of Zebra Mussels with Amiad Screen Technology

    Introduction The zebra mussel, native to the Black and Caspian Seas, has spread in the past few decades to waterways throughout the world mostly via ballast water. Zebra mussels, when non-indigenous to the environment, pose a serious threat to intakes of facilities that rely on fresh and brackish surface water.

  • Building a filter defense against Zebra and Quagga mussles

    Tiny mussels can create massive problems for intake structures, vaLves, pumps, screens and other water infrastructure around the US. Some filtration systems can provide chemical-free protection against invasive zebra and quagga mussels, but it is vital to understand the problem and develop the right system to avoid being overrun by the alien species. Zebra mussels (Dreissena polymorpha) and their ...

  • Underwater Robots Perfect for Power Production

    Underwater exploration, fish farms, dive jobs, marine research, municipal and commercial water utilities are obvious industries for the utilization of Deep Trekker mini-ROVs and pipe crawlers. However another industry that has seen remarkable success integrating underwater inspection robots is energy production. Diverse methods of creating energy provide a number of applications which benefit ...
