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.

Control Narrative: How Do Water Treatment Plant SCADA & RO Membrane Treatment Systems Communicate?

Posted by Julie Nemeth-Harn on Nov 2, 2020 9:00:00 AM

The following is a brief narrative describing the intended control strategy between each a Reverse Osmosis (RO) train and the water treatment plant SCADA system. 

It describes the control system we will supply and outlines the basic operation of a Reverse Osmosis skid and the required handshaking with the water treatment plant SCADA system. This narrative in no way encompasses all of the responsibilities of the water plant SCADA as we are not familiar with all of the requirements of the end user.

How to Calculate Percent Recovery and What Affects it in a Membrane Treatment System?

Posted by Julie Nemeth-Harn on Oct 5, 2020 1:10:00 PM

Membrane systems operating at 82% recovery will convert 82% of the total raw water input into treated permeate, with the remaining 18% being sent to waste as concentrate (or reject). The recovery rate is monitored using flow meters installed in the permeate and concentrate piping.

Everything You Need to Know About Membrane Cleaning

Posted by Julie Nemeth-Harn on Aug 17, 2020 9:45:00 AM

During normal operation of an R/O water treatment system, the membrane elements will often suffer a reduction in performance due to the accumulation of small particles, colloids, microorganisms, or precipitated salts collecting on the membrane surface.

What is Membrane Water Treatment Technology and Why Do We Specialize In It?

Posted by Julie Nemeth-Harn on Aug 3, 2020 10:15:00 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.

How Much Water on Earth is Drinkable?

Posted by Julie Nemeth-Harn on Jun 23, 2020 8:30:00 AM

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.
