Top 5 Uses for Reclaimed Wastewater

Posted by Julie Nemeth-Harn on Jan 25, 2021 9:15:00 AM

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.

Membrane Water Treatment: A Simpler and More Cost- Effective Process Than You May Think

Posted by Julie Nemeth-Harn on Dec 21, 2020 11:44:00 AM


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.

Use Variable Frequency Drives to Save Energy in Membrane Plants

Posted by Julie Nemeth-Harn on Jan 17, 2020 1:35:00 PM


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.

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

Improve Your Existing Water Treatment Process with a Membrane System

Posted by Julie Nemeth-Harn on Mar 6, 2018 10:02:00 AM

Membrane filtration systems are helping water treatment providers simplify and automate their processes while significantly improving water quality. Replacing or augmenting conventional treatment with membrane processes helps avoid heavy use of chemical processes and methods and can provide a superior finished water quality.
