Overcoming The Global Water Crisis: A Focus On Wastewater Recycling & Water Reuse
2/1/2021
While it is true that more than half of our planet’s surface is covered in water, a vast majority of it is saline. Fresh water, the water we use in hundreds of ways every day, constitutes only 2.5 % of all the water on the Earth. Today, the world faces what is known as the water crisis. Parts of the world do not have access to this most vital resource on the planet. Therefore, a focus on water recycling and water reuse is required to optimize the use of our critical water resources.

Seawater Desalination Using RO Membranes To Support A Thriving Agricultural Economy
4/8/2020
As the agriculture economy boomed, needs for freshwater demanded by irrigation, tourism and the local community also grew in Campo de Dalías, a coastal region on the Mediterranean Sea. As a result, the region faced overexploitation of groundwater aquifers. Read the full case study to learn how Toray was selected as the sole membrane supplier for a two-pass system for a newly implemented national desalination plan.

How To Score High Marks For Low-Pressure RO Performance
1/22/2020
For water system operators, contract engineers, OEMs, and reverse-osmosis (RO) membrane suppliers alike, the difference between expectations for RO membrane element performance and quantifiable performance in the actual operating environment can be fraught with surprises. This article addresses guidelines for establishing realistic RO warranty performance criteria and achieving those criteria in real-world applications.

Harness The Power Of The Sun For Off-The-Grid Desalination
8/8/2019
Industrial and population growth continue to outpace the supply of freshwater resources in many regions of the world. The need for additional freshwater resources is driving the need for desalination. When combined with concerns regarding climate change and harmful impacts associated with fossil fuels, desalination powered by renewable energy should be considered as a necessary part of the solution.

Defending Against Saltwater Intrusion
7/16/2019
Are “ghost forests” a sign of things to come? Rising sea levels and superstorm tidal surges are already impacting coastal areas, with rising salinity levels affecting some drinking water sources. Coastal water utilities are not the only ones that have to worry about salinity, however, as high concentrations of winter storm road treatments, gas drilling, and mining can also generate elevated salinity levels in surface water sources.

Total Dissolved Solids: A Matter Of More Than Just Good Taste
7/15/2019
Everyone wants good-tasting water, but most water treatment plants (WTPs) are hostages to the composition of their local source water supplies. One of the components involved in taste is total dissolved solids (TDS), which can affect both the acceptability of finished water taste and its likelihood to corrode or clog pipes and fixtures. Here’s how to quantify the problem and what to do about it if it is excessive.

New Technology Will Be Key To Higher Recovery Rates
7/3/2019
A growing number of regions with stressed water resources are focusing on improving their rate of recovery. Being able to tap into new technology to increase recovery will be key to meeting water demands while avoiding waste and practicing sustainability. In this Water Talk interview, Rick Myer, business development officer for Magna Imperio Systems, discusses new solutions for water recovery and energy savings. This includes systems for brackish water desalination, treatment of high-silica waters, and brine recovery applications which are now available to industries and municipalities worldwide.

Minimum Liquid Discharge – The Best Bang For Your Buck
6/27/2019
Fresh water sources around the globe are becoming increasingly stressed due to population growth, industry use, and changing climate patterns. These stresses drive the need to make the most out of every drop of water available. Water treatment systems inherently produce a waste stream that contains contaminants removed during the treatment process. This waste stream can often constitute 20-30% of the total water fed to the treatment system, representing a significant loss of a precious resource both in human and economic terms. Minimizing this waste stream is a key part of the solution to solving the water crisis for both industry and people.
