• 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.

• Better CAPEX, OPEX Options For PFAS Treatment

  The documented performance of ion exchange (IX) resins for treating per- and polyfluoroalkyl substances (PFAS) offers new opportunities for more practical solutions in many applications. IX has demonstrated its ability to reduce both capital and operating costs compared to the conventional granular activated carbon (GAC) treatment approach.

• The Natural Way: Biological Treatment For Groundwater Contaminant Removal

  Nature has long provided guidance to simple and sustainable ways to manage environmental challenges. Biological treatment of potable water is no exception. As more water is required to support human activity worldwide, sources once considered too contaminated or expensive to treat are quickly becoming necessary options. For groundwater contaminant removal, once again, the laws of nature point the way.
