ERD Efficiency: What System Builders and Consultants Need to Know
Executive Summary There is no standard definition of efficiency for energy recovery devices (ERDs). Each supplier is free to create their own definition that (not surprisingly) often favors their particular technology. Download the White Paper This

Motorized Turbochargers
Executive Summary Energy Recovery Devices (ERDs) are widely used in seawater reverse osmosis (SWRO) systems with turbochargers and rotary ceramic isobaric chambers or CICs dominating the market. The White Paper ERD Efficiency – What Systems Builders

Why We Custom Design Every Turbocharger
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)

Brine Flow Pressure Control in RO Systems using Turbochargers
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. Download the White Paper The other function of the

Comparing Energy Recovery Devices: HPB Turbochargers vs Pelton Wheels
There are many benefits of replacing a Pelton Impulse Turbine with a Hydraulic Pressure Booster or HPB. 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 HPB is
