Humans Are Depleting Groundwater Worldwide, But There Are Ways To Replenish It
1/25/2024
Groundwater is a renewable resource, but it can take decades or even centuries for some aquifers to recover after they are depleted. Current understanding of this challenge is based mainly on where and how frequently people record measurements of water levels in wells. In a newly published study, our team of data scientists, water specialists, and policy experts compiled the first global-scale dataset of these levels.

Using AI To Reduce OPEX In Wastewater Treatment
4/28/2020
For municipal and industrial wastewater treatment managers and support staffs, the prospect of using artificial intelligence (AI) to guide better decision-making sometimes seems more like a distant promise than a ready solution. Here are some insights on how AI can use historical data to improve operational intelligence and optimize processes, plus guidelines on how water professionals can do more to harness that power sooner.

Straight Talk On Radiation
6/22/2015
From time-to-time I write on topics that are related to water and wastewater as a "backgrounder" so that those involved in the field can gain a wider perspective and have available to them a cogent explanation minus jargon on various topics. By Dr. J.H. Wakefield

Here's How Wastewater Facilities Could Tackle Food Waste, Generate Energy, And Slash Emissions
8/3/2023
Most Australian food waste ends up in landfill. Rotting in the absence of oxygen produces methane, a potent greenhouse gas. While some facilities capture this “landfill gas” to produce energy, or burn it off to release carbon dioxide instead, it’s a major contributor to climate change. Valuable resources such as water and nutrients are also wasted.

Ion Exchange Resins Reduce Pollution From Refineries
12/23/2013
A single operational oil and gas refinery produces millions of gallons of contaminated wastewater a year, leading to environmental pollution concerns. Ion exchange resins are a metal- and ion-removal solution to help clean this wastewater for plant reuse or safe disposal. This application guide explains how resins can be used to demineralize refinery water in process, boiler, and cooling water applications.

Slashing Recycled Ammonia Loads From Dewatering Sidestreams
12/9/2019
Recycling is generally considered a positive thing, except when the sidestream discharge from the dewatering of anaerobic digested sludge can recycle up to 40 percent of the total nitrogen or ammonia load in the original flow back to the head of the wastewater treatment stream. Deammonification technology using anaerobic ammonium oxidation/anammox bacteria offers a cost-effective way to break that vicious cycle and meet regulatory discharge limits.
