The next generation of desalination will rely on multi-stage, high recovery reverse osmosis, delivering a lower cost of water and improving membrane performance.

Executive Summary Seawater reverse osmosis systems (SWRO) are the mainstay of large-scale desalination systems. Plant designs have settled in a more or less standard configuration using a single membrane stage with permeate recoveries ranging from

Executive Summary Reverse Osmosis (RO) systems are widely accepted on offshore platforms and vessels.These marine applications require compact size, good efficiency and low weight and the utmost in reliability as a failure can result in large

Executive Summary This White Paper addresses the impact of ERDs on the energy consumption of the RO process using an objective and fully transparent criteria. The analysis shows that published ERD efficiency data has virtually no correlation to the

What is Water BearingTM technology The Water Bearing™ technology was developed for all FEDCO pumps to increase reliability and maintenance for reverse osmosis systems. The patented FEDCO Water Bearing™ uses the pump discharge pressure to produce a

Executive Summary This paper will focus on the motorized turbocharger ERD or HEMI (Hydraulic Energy Management Integration) for SWRO applications. The HEMI can often have the lowest SEC value of any commercially available ERD. Energy Recovery

Turbochargers are simple machines but represent a daunting hydraulic design challenge: Design the turbine end to create a pressure differential to match the brine flow and pressure duty point; Design the turbine with a best efficiency point (BEP)

Executive Summary Turbochargers have come to dominate small and medium SWRO brine energy recovery applications by virtue of low CAPEX, easy operation and very good energy recovery efficiency. The other function of the turbocharger is to help

There are many benefits of replacing a Pelton Impulse Turbine with a Hydraulic Pressure Booster or HPB, with energy savings realized in the range of 6-20%. Total costs of HPB are typically 50% less than the cost of the Pelton Impulse Turbine. The

When you need to order parts or service on your FEDCO pump or energy recovery device, you will need to know the Model Number and Serial Number, These reference numbers allow us to retrieve the engineering specifications for your equipment to enable
