Flow Capacity Increases Up To 100% With Leopold
TexlerTM Lamella Clarifier
Breakthrough Design Uses Inclined Hydrophobic
Geotextile Lamella Sheets To Increase Water Production
Global water technology company, Xylem (NYSE:XYL), has today
unveiled a breakthrough solution to support the efficient removal
of solids in water treatment applications. Xylem’s new Leopold Texler lamella clarifier is unique to the
market as its lamellas are made from a recyclable, hydrophobic
geotextile material – a durable, high-density polyethylene (HDPE) –
which reduces service and maintenance requirements while cutting
solids by more than 80%.
Current lamella plate clarifiers are made from heavy stainless
steel plates which require extensive support structures and
significant capital investment. When exposed to sun, steel reflects
ultra-violet (UV) rays and promotes algae growth in the clarifier,
reducing the clarification 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,
which significantly reduces the overall construction costs while
increasing the flow capacity by up to 100%*. Carbon dioxide (CO2)
footprint for raw material production is reduced by approximately
80% due to a change in material from virgin stainless steel to
virgin HDPE, along with reduced material weight.
Texler comes with a UV cover to prevent algae growth and protect
against debris entering the clarifier. Unlike steel plates, HDPE is
also 100% corrosion free. This extends the lifetime of the product
and significantly reduces service and maintenance requirements. An
innovative trough cover design provides a catwalk for operators to
access the system for servicing, eliminating exposure to slippery
walking surfaces.
Salvador Dominguez, Global Product Manager at Xylem said,
“Utilities are under pressure to meet growing demand for clean
water. This challenge is paired with aging infrastructure and
tightening resources. The Leopold Texler lamella clarifier will
help solve these challenges, reducing the overall construction
costs, minimizing maintenance and providing a flexible and
sustainable solution that can be easily retrofitted into existing
basins, helping utilities to cost-effectively increase treatment
capacity and improve service for their communities.”
Xylem’s Leopold Texler employs a proven lamella clarifier design
feature whereby lamella sheets are installed at an inclined 55°
angle to significantly 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. As a result, water
treatment capacity of existing rectangular clarification systems
can be increased by up to 100%, with over 80% reduction in solids
and turbidity values starting as low as 1 NTU. The Texler
solution’s modular design allows for easy maintenance as each
lamella sheet can be easily removed independently.
