The plants are constructed to the same exacting standards that have become the trademark of GEA Filtration quality Membrane Filtration plants, but the membrane area is delivered in the larger 8” diameter sanitary, spiral wound format and is housed in 8” sanitary vessels. The increased membrane packing density allows for an added level of compact design, saving valuable floor space. Additionally, the capital cost is reduced by the scale economics of the sanitary 8” spiral. The scale economics also contributes to a reduced membrane replacement cost, which represents a large portion of the total operating cost in a Reverse Osmosis plant.
