Pump Engineering, Inc., of Monroe, Michigan has undertaken the task of developing an energy recover device (ERD) that isrugged enough to withstand the rigors of long term reverse osmosis (RO) operation, has improved efficiency torecover energy at low pressures and flows and, importantly, can be economically purchased. Theirsuccess has been translated into the LPT Turbo line of products. These devices are basicallystainless steel 304 or 316 in construction (lower cost and durable) and have been designed using thelatest 3D CAD and CAM computer software (high efficiency complex geometry impellers). Theturbine rotors and pump impellers are manufactured on 5 axis CNC milling machines.This paper describes the LPT Turbo and its successful application in a number of RO plants. Dataand energy consumption for these low-pressure facilities are provided. Also, applications of theLPT Turbos in related water treatment plants are discussed. Includes 3 references, tables, figure.
