Water treatment membrane systems are complex. Even after the technical design is finalized, it can be difficult to assess cost versus value. We all know from purchasing anything from shoes to washing machines that the cheapest product probably won’t provide us the best value.

Membrane Installation Components

Membranes are loaded from the feed end of the pressure vessel. To better understand the installation procedure, the following definitions are helpful:

Membrane water treatment is a process that removes unwanted constituents from water. A membrane is a barrier that allows certain substances to pass through while blocking others. Water treatment facilities use various types of membranes and processes to clean surface water, groundwater, and wastewater to produce water for industry and for drinking. It is a multi-billion dollar industry that is growing as a result of increasing concerns about contaminants in water and decline in safe, clean, easily accessible existing water sources.

Water quality and purification processes have improved over time, while demand for drinkable water has increased. Today’s membrane treatment plants can be tailored to the overall composition of water to be processed, and the membrane treatment methods used can reduce more possible contaminants. Where the desired outcome is stable, clean water with an appreciable return on the investment, upgrading to a membrane water treatment system is backed by cutting edge industry science.

An important part of operating membrane systems is accurate data collection on a daily basis.  The data will help predict normal maintenance schedules and will help determine the cause of any system upsets.  Comprehensive data is very useful in determining when the membranes need to be chemically cleaned, or eventually replaced. It also alerts the operator to changes taking place such as fouling, leaking “O” rings etc.

During normal operation of an R/O water treatment system, the membrane elements will often suffer a reduction in performance due to the accumulation of small particles, colloids, microorganisms, or precipitated salts collecting on the membrane surface.
