De Nora to supply filter underdrains for water plant upgrade in the Philippines

De Nora Water Technologies Inc is partnering with Japanese engineering company JFE Engineering to upgrade the largest water purification plant in the Philippines.

As part of the upgrade to the La Mesa water treatment plant, De Nora will supply TETRA™ LP Block™ dual parallel lateral filter underdrain blocks for 24 filter cells. The upgrade will help the plant to keep up with rising demand for domestic water and to ensure the works can effectively handle high flow events as experienced during heavy rains. The filter underdrains ensure that air and/or water is distributed evenly across the entire filter floor during the backwash cycle. This helps to not only remove solids effectively but also lowers the volume of backwash water produced, thereby reducing operating.

The La Mesa water treatment plant supplies water to approximately six million people in Metropolitan Manila. The upgrade will help to increase the plant’s quality and enable it to achieve a sustainable supply of water even during high turbidity events, ensuring optimal operational efficiency.
