Azud Luxon LEM Automatic Screen Filters with electric controls have been developed especially for industrial or urban applications, and for applications with high flow rates with large range of filtration grades.
The automatic multicartridge screen filter Luxon LEM is composed of 2, 3 or 4 Luxon LDB filtering elements (where self cleaning is made by suction).
FEATURES & ADVANTAGES
Azud Luxon filters continue to supply filtered water without interruption during the flushing cycle.
Filtration stage: Azud Luxon LEM is composed of 2, 3 or 4 Luxon LDB filtering elements working simultaneously in a large container. Water flows into the filter through the inlet (1) and enters the internal space of the filter elements. The water then passes through the screens (2). Particles remain on the inside of the filter elements (screens). Filtered water flows out through the outlet (3).
Backflushing stage: When the pressure differential from inlet to outlet (ΔP) reaches the pre-selected level, the flushing cycle starts. A hydraulic valve opens in the drain port, which starts the suction in the inner nozzles (4). This, along with the helical movement up and down the screen, brushes and sucks the captured particles into the waste flow. The trapped particles are expelled out the drain port (5).
The length of the flush cycle is pre-determined by the control unit. When the cycle is complete, the flush valve closes and the flushing ends. The flushing process uses a minimal amount of water.
