Selenium Removal Technologies: A Review
Selenium, a contaminant of concern in industries such as mining, oil refining, and power generation, is removed from wastewater principally through either biological or chemical/physical processes. This article will describe those technologies, several technology providers, and other sources of information.

The Water-Energy Nexus
September 2020, water joined precious metals, oil and other commodity futures traded on Wall Street amid fears of scarcity. In October, Chart Industries, Inc., a global manufacturer of engineered equipment for the industrial gas and energy industries, announced its acquisition of the water cleantech company BlueInGreen, LLC., which Chart’s CEO and President, Jill Evanko, described as a ‘natural fit’.

Thermal Flow Meters Help Electric Power Plants Keep Their Cool With Hydrogen Gas
In all electric power generation plants (gas, solar, coal or nuclear), the fuel source of choice heats a large boiler, which creates steam that drives turbine blades to rotate. The turbine shaft in turn spins magnets inside the generator, which induces an electrical current in a coil of wires. It’s a high-temperature process both in terms of the boilers and steam, but also at the back end of the process where the electric current generates a large amount of heat that must be managed in order to keep the generator’s wire coils cool enough to avoid degradation or failure. Depending on the MVA size of the generator, hydrogen (H2), air or water is typically used to provide cooling.

A Better Option For Water Transfer In Oil And Gas Applications
Until recently, it was difficult to find an optimal meter for the harsh conditions that can occur during water transfer in oil and gas applications. The good news is that an effective, accurate, and rugged meter is emerging as an alternative.

Lessons From Nestle's Zero Water Facility
Under pressure to avoid using Southern California’s endangered groundwater supply, Nestlé has announced plans to convert a Modesto milk factory into a “zero water” facility capable of extracting water from the materials it manufactures and reusing it for industrial processes.

The Rotostrainer Joins The Craft Beer Revolution
Spent hops and general brewery wastewater are natural by-products of the beer-making process and must be reused or disposed of accordingly. Some brewers are charged substantial fines for dumping high-solids wastewater into the city sewer system. With Parkson Rotostrainers, over 90% of the Biological Oxygen Demand (BOD) of wastewater can be filtered out, greatly reducing the city sewer charges. Many breweries can even sell much of the spent grain and other captured solids to local farms as livestock feed, thereby profiting on an otherwise ‘waste’ product.

Methods To Control Odors From Anaerobic Digester Plants And Prevent Nuisance To Nearby Communities
Anaerobic digestion is a practical and efficient technology to utilize considerable amounts of organic waste from intensive animal production and food processing and wastage during distribution/consumption, municipal waste, etc. to produce methane gas for electricity generation, local/process heating, and direct injection into the gas supply network.

Successful Screening Pilot At A Major Waste-To-Energy Player
Parkson recently had a very successful pilot test at the facility of a bio-feedstock supplier of waste products turned into fuel. The Rotoshear® unit, equipped with a .060” wedgewire screen, successfully removes solids directly from Industrial Waste Hauling trucks to recover grease. Screening this material before it enters the receiving station allows the facility to focus on proper treatment of the industrial wastewater rather than the expensive downtime to drain and clean their receiving pond.

It's Time For Industrial Treatment To Find A Phosphorus Alternative
Amid growing concerns around algal bloom, industrial operations are under pressure to stop using phosphorus-based water treatment technology. But transition to an alternative can be daunting.

Developments In Heat Transfer Technology Can Improve Exchanger Efficiency And Reduce Water Demand
Water’s high heat capacity, high thermal conductivity, and historically low cost make it popular for process heat exchange. Power plants, especially those for liquid cooling applications, withdraw a large fraction of the total demand for water necessary for agriculture, industry, recreation, hygiene, drinking, and wildlife.

Coal Ash Pond Polishing Filter System
A power plant's wastewater was being contaminated by coal ash generated from power plant operations. The plant was searching for a treatment/polishing system to maintain a TSS of less than 25 PPM.

A Roundup Of Energy, Water, And Climate Bills In The 84th Texas Legislative Session
We’ve almost made it to the midway point of the 84th Session of the Texas Legislature. As many already know, the Texas Legislature only meets from January to May every other year, so a lot has to get done in these few months.

3 Hidden Traps Of Low Flow Cutoff
Failure to capture meter readings at the low end of the production scale is a missed opportunity for steam system operators. Here’s why that is happening and what you can do to attack the problem.

Water Treatment In Boilers And Cooling Towers
Most people recognize problems associated with corrosion. Effects from scale deposits, however, are equally important. For example, as little as 1/8" of scale can reduce the efficiency of a boiler by 18% or a cooling tower heat exchanger by 40%!

Wastewater Collection And Treatment: General Observations
In this discussion, I am going to discuss general issues in wastewater treatment and specifically the collection phase of waste treatment. We all realize the effort and expense that goes into treatment-plant technology, but many don’t seem to realize that the collection phase is where we get “more bang for the buck.”

Filtration For World's Largest Recirculating Whitewater River
As part of a continuous maintenance improvement plan, the Amiad Superflow Galaxy water filtration system needed to be replaced at the U.S. National Whitewater Center, while fitting into the existing installation area and not increasing the system's footprint.

Water Is Food
Celebrating Earth Day always reminds me of the great Arthur C. Clarke's observation that we shouldn't have called our planet "earth," but "ocean" instead — after all, it's mostly water. The same is true of food: most food is literally largely water, and every morsel of our food figuratively floats on a sea of water that was necessary to produce it.
