Aqua's extensive research and development efforts over 17 years have resulted in the OptiFiber family of cloth filtration media. Its engineered, application-specific media offers unique performance characteristics, a variety of construction materials, solids storage depth, and less operator attention and maintenance requirements. More than 600 systems have been installed worldwide with field-proven results. The media is ideal for tertiary filtration, reuse and phosphorus removal in new plants and retrofits.
