Abstract
A modularized filtration system includes multiple production modules mechanically coupled in series to form a production chain, and fluidly coupled by parallel feed fluid, waste fluid, and product fluid flowpaths. The system also includes a turbine, work exchange unit, or other energy recovery device to extract energy from the waste fluid. The system may also advantageously include a pressurization device for pressurizing a feed fluid, and provide a common drive shaft for the energy recovery and pressurization devices.
Claims11
A filtration system comprising:
- at least two production modules mechanically coupled in series and fluidly coupled in parallel to form a production chain;
- each production module having a common feed fluid flowpath, a common waste fluid flowpath, and a common product flowpath carried along the production chain;
- an energy recovery device fluidly coupled to the at least two production modules that derives energy from a waste fluid in the waste fluid flowpath;
- and
- a pressure pump coupled to the production chain to provide pressurized fluid to the production modules.
