    Energy Recovery Devices for RO Membrane Systems

    The answer to your question depends on the expected life of the facility and the cost of electricity in your area. We included them in a brackish groundwater design near Phoenix but the project was ultimately shelved due to the housing market and the economy.http:/www.spi-engineering.com

    Internal Tank Coating Question

    Thanks guys. The vent line has dryers, dilution was considered. This system is going in upstream of an RO facility so iron was a concern. I hadn't considered SS as an alternative although it is definately worth suggesting to the design team.
