Are your current pressure-boosting pumps the best design for your operating conditions? Are they maximizing value from your operating budget with peak efficiency? How can you know for sure, and what can you do if they are not? Here are some guidelines for evaluating performance efficiency in pressure-boosting applications and for choosing the best pump configurations for new or existing applications.
It has been said that the unseen and untreated can break down any system — this phrase could not be more accurate than in the world of wastewater treatment when considering the infiltration of grit into a system. Infiltration happens in the collection system, whether it’s from living on the coast, aging infrastructure or just plain old build up over time.
Business people love to talk about "disruption." They pride themselves on eating their competitors' lunch. Where their markets used to be about raving fans, now it's about inspiring craving fans, fueled by "hunger marketing" and the fear of missing out. There's a lot of dog-eat-dog philosophy...which is why it's important for companies to be willing to cannibalize their own technologies.
The City of Silverton is known as Oregon’s Garden City and sends one million gallons a day of treated effluent to the Oregon Gardens, returning the remainder to Silver Creek.
There are many facets to industrial processes — raw materials, skilled labor, well-designed equipment, and sound methodologies. Optimizing those manufacturing processes requires consistent, reliable feedback on performance efficiency and output quality. Here are several guidelines for implementing continuous monitoring to keep process integrity at optimum levels.
Potable reuse offers a massive opportunity to recover water from the wastewater process, but projects face a variety of barriers to getting off the ground. Most successful early adopters engaged early with their constituents and implemented smaller-scale demonstration projects that were accessible to the public to prove the technology and process.
Large-scale water-reuse treatment plants have had sustainable impact in populated areas where the volume of water to be treated and reused in a concentrated area makes them practical. Today, the flat-sheet membrane aerated biofilm reactor (MABR) technology that is delivering high-quality wastewater treatment to remote locations is poised to realize the promise of sustainable water reuse in those same locations.
Over the last several years the wastewater reuse segment of the water industry has experienced both rapid growth and tremendous change. Global demand for increased water supplies fuels the development of alternative water sources, including reclaimed wastewater.
Title 22 of California’s Water Recycling Criteria is among the strictest water treatment standards for water recycling and reuse in the United States. Fluence’s MABR demonstration plant was installed at the Codiga Resource Recovery Center (CR2C) in Stanford, California, in January 2018 for the purpose of third-party evaluation. The testing parameters included criteria to evaluate reliable enhanced nutrient removal in the form of Total Nitrogen, which is increasingly important across the United States and difficult and costly to achieve through conventional wastewater treatment.
In September of 2016, Ted Henifin took the first sip of water purified at a pilot treatment plant developed by HRSD (Hampton Roads Sanitation District). Now, the innovative water treatment program known as SWIFT — Sustainable Water Initiative for Tomorrow — is changing the lens through which communities and government officials view wastewater, drinking water, aquifer replenishment, and even fighting sea level rise.
The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.
A Q&A with scientist Jeff Urban, who explains forward osmosis and how Berkeley Lab is pushing the frontiers of this emerging technology
Isn’t it ironic that our beautiful blue planet, covered 70 percent with water, is struggling to meet citizens’ water needs? Yes, and the reasons are obvious. Out of the Earth’s total water, less than 3 percent is available as freshwater, and a portion of it is actually accessible. Uneven distribution of fresh waterbodies and population across the globe further skew water supply and demand ratios. Also, climate change, deforestation, desertification, droughts, floods, and depletion of natural waterbodies resulting from anthropogenic and natural activities add to these miseries.
The technology is ready, but is the world ready? The seismic shift toward water reuse will occur only as driving circumstances reach their tipping point.
Everyone is familiar with the water cut statistics: three to seven barrels of produced water emerge from the ground per barrel of oil. This oft-cited statistic is useful to appreciate the scale of the volumes of water produced in the Permian Basin. However, it does not tell the whole story.
Water is essential to life. And it is a very precious commodity in Israel, home to 9 million people living in a rocky desert that receives about 10 inches of rain a year. By comparison, Denver, considered semi-arid, gets about 15 inches of rain a year, which is about a fourth of the precipitation a tropical city such as Miami receives.
Collaborative research is a critical element for identifying unforeseen risks associated with using the oil industry’s wastewater outside the oilfield. That’s the recommendation of a new peer-reviewed paper accepted this week in the Journal of Integrated Environmental Assessment and Management (IEAM).
