De Nora has more than 50 years of experience and over 1,300 installations providing media filtration solutions to both municipal and industrial markets. A variety of filtration products allows De Nora to customise filter design for optimal performance in a particular application. Common municipal applications include pre-treatment of seawater for desalination, filtration of drinking water sources, and tertiary treatment of wasterwater - although Fluidquip Australia offers solutions specifically targeting drinking water.
The filter underdrain is one of the most important components contributing to overall filter performance. Fluidquip Australia offers dual parallel lateral underdrain products including DE NORA TETRATM U, LP, and Anchor-Rite® BlocksTM, all of which provide a unique non-clogging underdrain for heavily-loaded applications. These underdrains accommodate a wide variety of granular media types and sizes that are preferentially configured to provide the benefits associated with a DeepBedTM filtration concept. The underdrains provide excellent distribution of backwash air and water for efficient bed cleaning and low filter operating costs for new or retrofit applications. These underdrains are simple to install, require minimal maintenance, have no moving parts vulnerable to wear, and provide consistent performance over a long life.
