New Concept of UF: Integrated-UF (I-UF)

Interest in the Innovation Fluytec has designed a new product line that combines two concepts: Elimination of the housing and the accessories of UF membrane modules, introducing UF fibers directly into a pressure vessel. Integration of UF pre-treatment within the same pressure vessel.
The resulting integrated UF (i-UF) provides the following benefits: The i-UF vessel is designed to work outdoors. This dramatically decreases investment costs and lead time, as the need for a UF building is eliminated. The plant’s footprint decreases, and fewer auxiliary elements are required (i.e. equipment, piping, valves, control elements, etc.). The cost of retrofitting UF membranes is reduced. In standard UF skids the complete vessel with the fibers needs to be removed, while in the i-UF only the fiber package is replaced. This also means that less waste is produced.
Water consumption is optimized, as the same cleaning water volume is used to clean both the UF membranes and the strainer. The pressure drop in the system is lower (no dP due to interconnecting piping and accessories), which improves the energy efficiency of the plant. Description of the Technology The i-UF combines a 100-300 ?m self-cleaning strainer and UF membrane cartridges in the same pressure vessel, generally made of fiberglass-reinforced polyester. This equipment includes actuated valves and pressure switches that will allow automatic backwashes. Both stages can be backwashed with the same water flow, ?thus saving on water and valves. If necessary, each stage could be backwashed individually.
