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 regulate brine flow and pressure to achieve the desired membrane operating conditions. Changes in feed temperature and salinity as well as membrane fouling and operating objectives require such adjustment.
This paper focuses on flow and pressure control of the brine stream in RO systems equipped with turbochargers.
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 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
