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.

Use Variable Frequency Drives to Save Energy in Membrane Plants

Posted by Julie Nemeth-Harn on Mar 20, 2018 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.

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.

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.

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.
