In municipal drinking water applications or pre-treatment for desalination plants using gravity filters, the filter underdrain is one of the most important components contributing to overall system performance and operation — whether a new filter design or retrofitting an existing filter.
The DE NORA TETRA™ LP Block™ dual parallel lateral underdrain from De Nora Water Technologies is a proven design of filter underdrain offering superior distribution of both backwash air and water, either sequentially or concurrently. The system is NSF61 and UK Secretary of State approved and also has certification for use with drinking water applications in other countries.
