Poseidon Filtration System®


Orthos nozzle-based monolithic underdrain systems have defined reliability for the past 20 years — we have never had an underdrain system failure. Poseidon extends this repetitious success by using our in-house engineering design expertise to provide complete filter systems for municipal water treatment.

With increasing water quality concerns regarding disinfection byproducts, nitrogen, phosphorus, taste, and odor, Poseidon delivers a systems approach that includes all requisite controls and components.
