The ROI of the disc filter system is very compelling: 1.47 years 1. OPEX savings due to lower average pressure differential 2. OPEX savings due to elimination of cartridge disposal The disc filter removes particles larger than 25u.m more effectively than the cartridges The disc filter removes dinoflagellates (red tide causing plankton) more effectively Cartridge effluent was unstable and showed compromised effectiveness, while the disc filter performance was stable and consistent.
