• Facilitating Innovation In The Water Sector

  Recently, Rich Cavagnaro and Ronit Erlitzki, from AdEdge Water Technologies, sat down with the Water Online editorial team. The discussion ranged from ways to treat PFAS and water to sustainability to how to facilitate innovation in the water industry.

• Tackling Arsenic With A Cost-Effective Strategy

  Arsenic presents a wide array of negative health impacts, which is why it is such a big concern for many municipal water systems. The contaminant is linked to multiple types of cancer — including bladder, lungs, skin, kidney, and liver, among others — and is known to cause of variety of other problems such as skin issues and intestinal issues.

• The Best Way To Remove Manganese From Drinking Water

  Water utility managers must constantly stay on top of regulatory changes. Water plant operators currently test for more than 80 contaminants, including manganese. Manganese is regulated under secondary drinking water standards for aesthetic considerations.

• How Community Growth And Other Changes Are Driving The Need For Expert Ongoing Field Support

  The process of launching a municipal drinking water treatment operation can take years. In the end, a community is left with a complex system, an operations and maintenance manual, and a well-trained staff. Many communities are extremely well versed in the functions and operation of their treatment for the specific parameters for which it was built. However, as time goes on, plant managers and operators increasingly have a need for outside assistance.

• Innovative Technologies For Nitrate Treatment

  Conventional nitrate treatment equipment tends to generate a waste-handling issue that can be a challenge to many utilities. The emergence of innovative technologies in drinking water treatment has led to more sustainable approaches for the reduction of nitrate.

• Deploying Iron-Based Adsorption Systems For More Efficient Arsenic Removal

  Removing arsenic from source water can be an expensive and tedious process. Anion exchange treatment technologies, for example, produce a brine/contaminant discharge, while reverse osmosis solutions generate a concentrated arsenic reject. By comparison, the only cost of a properly designed iron-based adsorption system is periodic media changeout.

• New RO And Other Techniques Lead To Improved Performance

  For water utilities facing various water contamination issues, there is no single catch-all treatment. That is why in this recent Water Talk interview Ronit Erlitzki and Doug Craver of AdEdge Water Technologies share treatment options that can be used alone or in combination to address diverse challenges. They introduce a new reverse osmosis (RO) treatment technique capable of raising recovery rates by 20 percent and reducing concentrate volume up to 70 percent vs. conventional RO (depending on water quality). They also explore biological processes for removing nitrate, VOC, ammonia, etc. and treating high brine concentrations in wastewater, plus techniques for resolving ammonia problems in water with high TOC concentrations.
