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.

How Do I Know I’m Getting the Best Value on My Membrane System?

Posted by Julie Nemeth-Harn on May 1, 2019 3:11:29 PM

Water treatment membrane systems are complex. Even after the technical design is finalized, it can be difficult to assess cost versus value. We all know from purchasing anything from shoes to washing machines that the cheapest product probably won’t provide us the best value.

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.

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.

How to Save Money and Avoid Issues in Your Membrane Water Treatment Plant by Using a Pilot During the Design Process

Posted by Julie Nemeth-Harn on Mar 15, 2017 10:46:00 AM
Pilot systems are the most cost-effective method of testing membrane plant designs. The basic idea is that a pilot system can be implemented at a fraction of the cost of the full system, and then full implementation follows after the design has been optimized and potential obstacles have been worked out.
