Gravity Filtration

Gravity filtration is a physical process for the separation of solids from liquids. Used for filtering potable water or treated wastewater effluent in tertiary treatment applications, the underdrain is the heart of every gravity filter. If the underdrain is well designed, durable and efficient, the filter will provide many years of continuous service. Ovivo's systems are designed to provide ease of operation, long filter runs, and reduced backwash water volume requirements.
