Basic overview of reverse osmosis and nonofiltration water treatment processes plus system design guidelines and considerations....
Pretreatment 2004: A Perspective
An briefing on the purpose, function and imprtance of well designed and operated membrane process pretreatment systems if offered. The potential consequences of membrane failures, scaling and fouling are reviewed....
Seawater Desalting By Reverse Osmosis: The Basics
The paper considers basic aspects of seawater reverse osmosis (SWRO) process design, from source acquisition to post-treatment. Consideration is given to surface vs. beach wells/collector systems; pretreatment needs and possible pitfalls; membrane system process design, including pump selection, energy recovery, flux, and staging. The effect of tem...
Pilot Testing the Center Port Vessel Design at the Town of Jupiter, Florida
The Town of Jupiter, Florida, is constructing a 17.0 MGD Nanofiltration (NF) plant at its Central Boulevard complex. The Town already operates at this site a 13.7 MGD brackish groundwater RO plant, and a 13.5 MGD lime softening plant, together with a 1.8 MGD ion exchange system, which removes organics from a shallow groundwater side stream for redu...
RO/NF Basics
Reverse Osmosis (RO) and Nanofiltration (NF) basics and a comparison between the two membrane processes. Introduction to technical terms used in describing these two membrane processes and characterizing performance....
