How Much Water on Earth is Drinkable?

Posted by Julie Nemeth-Harn on Jan 30, 2018 4:31:00 PM

Water is one of the most important commodities that supports life on earth but very few understand how hard it is to get clean, potable freshwater. Water, in all its forms, covers three quarters of the Earth's surface. The water levels on Earth remain relatively the same each year. Every day, water goes through a cycle that sees it flow from land, to the seas and then evaporates into the atmosphere through the processes of evaporation and precipitation.

Top 5 Uses for Reclaimed Wastewater

Posted by Julie Nemeth-Harn on Jan 16, 2018 1:10:00 PM

Whether commercial or residential, the modern world is currently seeing an increase in water reclamation practices. Reclaimed water, perhaps better described as "recycled water," is wastewater that has been filtered and treated for reuse, thereby limiting the need for fresh water use. This practice has increased in popularity over recent years. GAO reported 36 states as using reclaimed water in 2013, compared to just 23 states in 2003.

Introduction to a Harn R/O Systems Membrane Filtration Pilot Unit

Posted by Julie Nemeth-Harn on Nov 17, 2017 2:15:07 PM
In this RO pilot video, Jonathan Harn, project engineer with Harn R/O Systems, introduces one of our membrane filtration (MF) pilot units designed to operate standalone or as pre-treatment to our reverse osmosis (RO) pilot units. Membrane filtration is designed to remove suspended particles from water whereas reverse osmosis (RO) is designed to remove dissolved particles from water.

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

Posted by Julie Nemeth-Harn on Oct 4, 2017 3:09:17 PM

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 Sep 7, 2017 12:28:27 PM

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.

Everything You Need to Know About Membrane Cleaning

Posted by Julie Nemeth-Harn on Aug 24, 2017 11:22:14 AM

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.
