61. Industry Innovations For Reverse Osmosis Concentrate: A Challenging Liability Becomes A Valued Asset 9/22/2016

    Unlike dead-head filtration characterized by a single flow in and out, both reverse osmosis (RO) and nanofiltration (NF) technologies are unique in that they produce two effluent streams, a lower TDS (total dissolved solids) permeate and a higher TDS concentrate.

62. New Filters To Combine Processes And Cut Down Costs 9/9/2016

    Reverse osmosis is one of the most energy-intensive, and therefore costly, steps in wastewater treatment. A newly developed nanofilter may change that.

63. Industrial Water Treatment For Inorganic Contaminants: Biological Treatment Processes 8/9/2016

    This article is the fifth in a series on industrial water treatment focusing on inorganic contaminants. While regulatory limits are being established, the process of identifying a cost-effective treatment process should be undertaken. Potential water treatment processes for inorganic contaminants can be grouped into three categories: physical, chemical, and biological. This article will describe the biological treatment technologies that may be considered.

64. 10 Technologies And Breakthroughs From ACE16 7/14/2016

    This year's Annual Conference and Exposition (ACE16), held by the American Water Works Association (AWWA) from June 19 to 22, was the first following the tragedy of Flint — a time when the drinking water industry is under intense scrutiny.

65. The Cure For Membrane Biofouling 5/23/2016

    After reviewing multiple methods, engineers and operators at a Pennsylvania water reclamation facility discover a winning pretreatment formula for reverse osmosis biofouling control.

66. Fractional Electrodeionization (FEDI) Technology For RO Permeate Polishing And Demineralization 5/5/2016

    Sabine Pass, a large LNG refinery in the U.S., required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export.

67. Industrial Water Treatment For Inorganic Contaminants: Physical Treatment Processes 5/3/2016

    This article is the third in a series on industrial water treatment focusing on inorganic contaminants. 

68. Is Capacitive Deionization The Key To Desalination? 4/28/2016

    Capacitive deionization can remove ions, like salt, from water. With a lower energy cost than many other desalination methods, could it be the answer to drought?

69. Zero Liquid Discharge Opens Up Opportunity For Forward Osmosis To Make Its Mark 4/11/2016

    While many companies and investors have struggled to make sense of an entry point into the massive water industry, seeds are consistently being sown for those that know how to monitor and enter intelligently.

70. Membrane Fouling And Prevention: What Works And What's New 3/28/2016

    An overview of the current state of pretreatment technology is presented alongside the latest advances and innovative techniques in the pipeline.
