The Impact That a Hurricane Can Leave on Your Water Treatment Plant

Posted by Julie Nemeth-Harn on Jan 10, 2019 11:43:18 AM

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

How Global Warming and Climate Change Presents Major Water Treatment Challenges

Posted by Julie Nemeth-Harn on Oct 4, 2018 10:48:00 AM

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.

Why Daily Data Collection is Important and What Parameters to Use to Monitor Your Membrane System

Posted by Julie Nemeth-Harn on Apr 24, 2018 11:25:00 AM

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.
