Global water technology company, Xylem has unveiled its Leopold Texler lamella clarifier for the efficient removal of solids in water treatment applications.
Current lamella plate clarifiers are made from stainless-steel plates which require extensive support structures. When exposed to sun, steel reflects ultra-violet (UV) rays and promotes algae growth in the clarifier, reducing its performance and requiring regular, manual cleaning.
The Leopold Texler system uses hydrophobic geotextile, a woven HDPE which naturally repels water and reduces the need for cleaning. The flexible design allows for cost-effective retrofitting by using existing rectangular basins, significantly reducing the overall construction costs and increasing flow capacity by up to 100% compared with regular clarification systems.
The lamella sheets are installed at an inclined 55° angle to expand the clarification surface area. Solids settle on the lamella sheets as water flows through trough covers featuring an integrated v-notch weir, resulting in even distribution of flow throughout the clarifier. This means that the water treatment capacity of existing rectangular clarification systems can be increased by up to 100%, with over 80% reduction in solids.
