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.

Puralytics LilyPads are hardly noticeable in the ponds, lakes, and catchment areas where they are deployed. Made of mesh and plastic, the flat, 1-meter diameter disks could even be confused for their plant namesake if not for their white color.

The City of St. Cloud, Minnesota, straddles the Mississippi River near the center of the state a little more than 65 miles north of the twin cities of Minneapolis-St. Paul. The city’s forward thinking staff began looking for sustainable green energy solutions in 2003. After planning and initiating a series of projects over several years, the site is today producing renewable energy with a 20 kW rooftop solar array, a 220 kW solar array and biofuels electricity generation.

Many processes in the oil/gas refining, specialty chemical production, solvents, paint, coatings and photoelectric industries generate hazardous air pollutants (HAPs) and volatile organic chemicals (VOCs), which need to be removed from waste, flue and tail gases before emission into the environment to meet clean air regulations around the world. In addition to removing problematic greenhouse gases, emphasis is placed on eliminating toxins that can be harmful to industrial workers and the environment.

A thief hatch allows access for measurement, but if left open it can allow hydrocarbon vapors to escape into the atmosphere as fugitive emissions. 

As a young engineer on a farm in California's Central Valley grappling with the challenge of injecting fertilizer into irrigation water, Angelo Mazzei didn't consider how his career would ultimately turn his knowledge of water into a deep involvement in wine. But since he crafted first high-efficiency venturi injectors in the 1970s in his garage to help improve water, fate and business have pulled Angelo Mazzei toward wine from every direction.

Atlantium Technologies has revolutionized the treatment of simple syrups with its cutting-edge Hydro-Optic Disinfection (HOD™) technology.

At Schreiber Foods' wastewater treatment plant in Utah, mineral acids had been used for pH control in the past but were discontinued due to safety and handling issues. Facility owners desired a safer, more cost-effective solution that would provide automatic control over process pH levels. 

When a major pork producer sought cost-effective pumping solutions to one of its Kansas facility's wastewater systems, the search led to the installation of a Smith & Loveless above-grade pump station.

Wastewater from the meat processing facility is treated using a sequence batch reactor and an aerobic lagoon that discharges to surface waters following treatment. The facility replaced surface aeration equipment with two, 350-HP the “no-splash,” side-stream SDOX systems retrofitted to the treatment basin. Read the full case study to learn the results.

The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

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.

A West coast power plant needed an immediate solution to clean its cooling tower that was fast, cost effective, and did not require removal and manual cleaning of the tower's fill material. 

After an international tender process, the Israel Electric Company (IEC) chose Fluence to design, manufacture, and supply containerized ultrapure water production systems for use as makeup water for heat-recovery steam generators (HRSG) and for NOx emission reduction at recently upgraded power plants across Israel. More than 15 units of 20 m3/h production modules, each fitted in two 40-foot shipping containers, were provided to seven power plants. Their compact design allowed for ease of installation, operation, and maintenance while meeting the customer’s demanding engineering standards.

As regulations tighten and technology evolves, monitoring and removing pharmaceuticals and personal care products (PPCPs) from wastewater streams becomes more complex. A laboratory information management system (LIMS) may be the key to managing this complexity.

A chasm in the Clean Water Act, coupled with EPA’s misguided direction, create an environmental suing spree that threatens to cost everyone that pays a sewer bill $100 billion and more — for pollution you didn’t cause, using remedies that don’t work. There’s a way to turn this around and help the taxpayer and the environment, based on lessons learned in Iowa and Idaho.
