Ozone In Water Purification And Bromate Formation
4/19/2021
The ozonation process for water purification is a powerful option for optimal disinfection and the reduction of micropollutants. Still, it may result in the formation of potentially toxic oxidation byproduct bromate in bromide-containing waters. This paper provides a high-level overview of the problem and highlights the main pathways of ozone decomposition and propositions to control bromates formation.

Technologies That Can Achieve Water And Sanitation For All
3/26/2021
A staggering four billion people — two-thirds of the world’s population — experience water scarcity each year, and more than half lack access to safe sanitation services. The severity of this global water crisis will only increase as populations continue to rapidly grow, industries exhaust shared resources and extreme weather events exacerbate shortages. If we don’t act urgently, 700 million people could be displaced by intense water scarcity in just a few short years.

Deep Dive Into Data Reveals Powerful Ozone Story
3/11/2021
There's a lot of truth to the adage that knowledge is power — and what's equally true is that many of us don't realize the power that is literally at our fingertips. At Mazzei, we recently engaged in a six-month campaign to study opportunities in the ozone market for our venturi injectors and sidestream injection systems, which have been catching on in ozone installations covering a wide range of configurations and sizes.

Understanding Options When Selecting An Effective, Low-Cost PFAS Solution
2/5/2021
Municipal water utilities throughout the U.S. are increasingly grappling with the need to address PFAS once it is detected in source water. Because standards are a moving target while treatment options are limited and can represent a massive expense, addressing PFAS can be especially challenging for small water systems. The key to finding an optimal solution requires a thorough investigation of the available options.

A Natural Approach To Algae Treatment And Prevention
2/5/2021
Operators of lakes, rivers, reservoirs, and other waterbodies commonly introduce harmful chemicals and other compounds — such as antibacterials and bleach — in an attempt to rid the water of problems such as algae and toxins. However, with beneficial bacteria it is possible to achieve a balance in water or discharge by reducing phosphorus and other key parameters naturally, thereby eliminating or drastically reducing the food source for algae.

Pros & Cons Of Sea Water Desalination Using Reverse Osmosis For Drinking Water
2/2/2021
Sea water desalination is unequivocally the future of drinking water production for coastal communities and island nations in current times of water scarcity. It is already used quite heavily in a few countries. Saudi Arabia, the United Arab Emirates, and the United States are the top three desalination producers of drinking water by capacity in the world followed by Australia, China, and Kuwait.
