Three major hurricanes have already hit the United States this year. Being prepared for a hurricane has never been more important, especially for those who run and manage water treatment facilities. Water treatment is essential for removing constituents that can be unpalatable and lead to illnesses and other serious conditions. Houston experienced an outbreak of E. Coli due to water contamination from the impact of hurricane Harvey, which knocked out at least 40 water treatment facilities in the area. Water is essential for our survival so it is of utmost importance that water treatment facilities are prepared to handle and respond to natural disasters, like a hurricane.water
The effects of global warming and climate change are continuously being felt on the earth. In fact, we are expected to experience a 2-5 degrees Celsius increase in global temperatures within the next 30 years. An effect of climate change that often gets overlooked is its impact felt on water treatment processes.
Climate change poses major challenges to the effective treatment of water. Some of these challenges include inundated water supplies that lead to higher levels of contaminants in the water, pressure on the operation of current water infrastructure, and the effect of inclement weather on water systems.
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.
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.
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:
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.
