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.

Membrane Water Treatment Specialists: What that Means and How They Can Benefit your Water Treatment Project

Posted by Julie Nemeth-Harn on Sep 29, 2016 10:00:00 AM

Ever since the development of high quality synthetic membranes in the 1960s, there has been a rise in the use of membrane technology for water purification. Today, membranes are seen as a better, more cost-effective alternative to distillation-based techniques for desalinization of seawater, and conventional softening and filtration for groundwater.

Federal Regulations for Water Treatment Plants and How Membranes Help Meet Them

Posted by Julie Nemeth-Harn on Sep 22, 2016 10:00:00 AM

In 1974 Congress passed the Safe Drinking Water Act (SDWA) that set forth specific water quality standards, required monitoring for contaminants and required water suppliers to submit data and water quality reports that would be available to the pump. Since then many changes have been made to the SDWA – primarily related to adding additional parameters to be monitored and regulated. Many of these regulated contaminants are difficult to treat with conventional softening or filtration treatment technologies. Membrane treatment has become invaluable to help cost-effectively meet these increasing regulations for contaminants such as metals, fluoride, radionuclides, organics/trihalomethane precursors, and more. The ion rejection characteristics of reverse osmosis membranes makes them likely to be able to continue to meet more stringent water quality treatment goals – whether federally mandated or voluntarily adopted on a local level.

Brackish Water and Seawater: Make Potable with a Membrane Treatment System

Posted by Julie Nemeth-Harn on Sep 1, 2016 10:00:00 AM

It is no secret that sustainability has taken the world by storm.  In the workplace, the media, and even your own community, it seems to always be a topic of interest.  In the beginning, many environmentally sustainable initiatives were focused on resources such as forests and natural gas, among others.  However, in the face of dramatic population growth, the concept of water as a limited resource is also making headlines.
