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.
With growing worries about water scarcity, the need for businesses and homeowners to conserve water is becoming more and more evident. Fortunately, many of the ways that you can save water on an individual basis are free or inexpensive. Furthermore, almost all of them are relatively easy to implement. Consider the following ways to save both money and water:
Variable frequency drives (VFD) are becoming the popular choice for many industrial processes that need to make use of motors with changing speeds. In membrane plants, these motors are used to feed the pressure and flow of the water as it moves through the various areas of the treatment cycle.
Membrane filtration can be explained as a method of allowing certain materials to permeate a surface while blocking others. For water, this means allowing clean water to flow through the membrane while eliminating sediments and other materials or pathogens. Membrane filtration is a multiple-step process which is considered to be one of the most cost-effective water treatments available.
The following is a brief narrative describing the intended control strategy between each a Reverse Osmosis (RO) train and the water treatment plant SCADA system.
It describes the control system we will supply and outlines the basic operation of a Reverse Osmosis skid and the required handshaking with the water treatment plant SCADA system. This narrative in no way encompasses all of the responsibilities of the water plant SCADA as we are not familiar with all of the requirements of the end user.
