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.

Can Cars be Made to Run on Water?

Posted by Julie Nemeth-Harn on Jun 28, 2018 4:17:00 PM

It has always been the Holy Grail of automobiles – the car that will run on water. What would it take to build such a car? Innovation, skill, experience, and an immense amount of knowledge about water systems. It will also take a very good hydrogen generator.

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

Posted by Julie Nemeth-Harn on Mar 27, 2018 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.

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.
