Orthos Mid-2025 Advancements in Water & Wastewater Treatment
In 2025, we’re proud to highlight milestone projects that strengthen communities with innovative, reliable, and sustainable water treatment solutions.
-
Have you seen MAXIMUS™?
Orthos’ new stainless steel filter underdrain, MAXIMUS, solves a number of performance and installation issues and provides excellent distribution robust construction and quick commissioning.
-
What is a Filter Nozzle? Part II
Orthos highly recommends nozzles to be located as close as practicable—
this is to ensure effective media cleaning through more points of energy input
and to potentially eliminate gravel and other types of problematic packing layers. -
What is a Filter Nozzle? Part I
How do we know how to select the correct nozzle product for your application? Orthos has by far more injection molding capabilities and over a million nozzle design combinations in order to provide the correct solution for your application. R&D performed in our Orthos Research Center evolves new and improved nozzle products, while others still plug-and-chug mid-20th century legacy products in a one-size-fits-all manner.

Why to Use Baffled Wash Troughs
Did you know that Orthos manufactures media retention troughs for low-freeboard granular media filters? Ortho-Wash™ troughs are constructed of 304- or 316 stainless steel to provide long, clear spans, durability, and maintenance-free service.
-
Tired of Emergency Filter Underdrain Repairs?
ORTHOS can utilize the block channel (flume) for the installation of an air header and create a short plenum (±12″) to minimize hydraulic profile. With a change of media design, maximum backwash rate, or trough elevation, ORTHOS can engineer a solution that provides excellent distribution, long filter runs, and effective media cleaning.
-
Why Choose Orthos over Leopold, Roberts, WesTech, and De Nora?
Orthos has NEVER had a monolithic underdrain failure. Because of our nozzle back pressure design and that air and water move freely under the monolithic floor, distribution is repeatedly exceptional, resulting in optimal media cleaning and long-lasting structural integrity.

Utah Filter Rehab
Orthos Liquid Systems, Inc., (Orthos) the leading manufacturer of nozzle-based filter underdrain systems in water/wastewater treatment, helped Washington County Water Conservancy District (WCWCD) save millions of dollars through clever engineering design during last year’s filtration upgrade at the Quail Creek Water Treatment Plant (QCWTP) in Hurricane, Utah. Without adding any new filters, the facility can now process 60 million gallons per day (MGD) versus 48 MGD previously, a throughput increase of 25%.
