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.

What is Membrane Water Treatment Technology and Why Do We Specialize In It?

Posted by Julie Nemeth-Harn on Sep 6, 2018 10:44:00 AM

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.

How Much Water Do Americans Use Versus Other Countries?

Posted by Julie Nemeth-Harn on May 24, 2018 10:28:00 AM

Much of the environmental discussion of the new millennium has been centered on an individual’s carbon footprint. From running the shower to the continuous flow of the faucet as you brush your teeth, we have all heard statistics regarding how much water we use. Similar to our carbon footprint, we can estimate our individual water footprint.

4 Reasons You Need to Replace Your Conventional Water Treatment Plant with a Membrane Water Treatment System

Posted by Julie Nemeth-Harn on May 1, 2018 2:48:00 PM

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.

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.
