When developers of a condominium complex sourced wastewater treatment systems, it did so with two primary requirements: efficient land utilization and high effluent quality to meet stringent guidelines. State regulators advised the developers to discuss combining its wastewater system with the owner’s association of an adjacent housing development, whose existing wastewater treatment system was aging and required augmentation.
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.

Schreiber’s Peripheral Drive Clarifiers are favored because of their ability to accomplish rapid sludge removal and continuous collection and removal of floatables. Instead of the typical center-drive high torque arrangement, Schreiber Clarifiers utilize the mechanical leverage and mechanical simplicity of a peripherally driven system. A low horsepower single drive unit is all that is needed to rotate both the scraper and the skimming assemblies. The assemblies are suspended from a rotating access bridge or, in the case of smaller units, a lightweight rotating beam arm. The rotating skimming equipment removes floatables regardless of wind direction, and the helical scrapers convey settled solids to the center of the basin for removal in one revolution or less.
The PR 6241 range of load cells is specially designed for weighing small and medium sized process vessels and for high-precision dosing.

This technology is used to improve the thermal, mechanical, and chemical properties of cable insulation materials. RADOX® cables do not melt, possess better abrasion resistance and greater cut resistance than conventional cables and, even with thinner insulation, are much more resistant to various environmental factors.
Reliably delivering clean, potable water to customers is at the core of what every water utility does. Making this happen is a heroic effort, though, and requires constant attention to be able to fully understand how the system behaves, identify problems, and choose the best course of action to address the needs of the customers and the needs of the utility. Our tools are designed specifically to help engineers analyze and design water distribution systems.
The Parkson DynaSand® EcoWash® Filter is a unique system that filters liquid suspensions to the designed effluent quality, while at the same time cleaning the sand bed so the filter is not shut down during the backwash time. Feed water is passed upwards through the sand bed and exits the top of the filter as clean water. At the same time, sand can be removed from the bottom, cleaned and returned to the top. A small portion of the filtered water is used to wash the sand and leaves the filter as a reject stream.
Water and wastewater treatment plant design is a large scale, complex engineering effort requiring a design team, often spread across many offices, and involving collaboration between different consulting firms, contractors, and owners. Bentley’s solution creates multi-discipline 3D models that can optimize project delivery and improve the management of infrastructure asset information as the project passes from design into construction and ultimately through to operations.

That’s the recommendation of a new peer-reviewed paper accepted this week in the Journal of Integrated Environmental Assessment and Management (IEAM).
Denver Water is redeveloping its 35-acre operations complex with an eye on more than just delivering water.
This is the second of two articles looking at the increasing reliance of Australian cities on desalination plants to supply drinking water, with less emphasis on the alternatives of water recycling and demand management. So what is the best way forward to achieve urban water security?
Most people think as little as possible about the wastewater that is produced daily from their showers, bathtubs, sinks, dishwashers and toilets. But with the right techniques, it can become a valuable resource.
When it comes to answering questions about whether the oil and gas industry’s wastewater can be safely reused for other purposes, like food crops, livestock, or even drinking water, there are a number of other serious factors to be considered.
While San Diego has a reputation for beautiful weather in a sunny seaside setting, its growing population in the southernmost area of rain-starved California is a recipe for trouble in paradise. That challenge has spurred the creation of Pure Water San Diego — a multi-phase, multi-year program with the goal of using recycled water for up to one-third of San Diego’s water supply by the year 2035.
Partnering with the Water Research Foundation, Brown and Caldwell has developed the Blueprint for One Water — a user-friendly document for the practical application of 'One Water' planning. According to Lisa Skutecki, Brown and Caldwell's Southern California Water Resources Group Manager, 'One Water' is the concept of breaking down barriers across the water sector.
As water reuse becomes increasingly common, more utilities will get to know ozone. To explain its role in water treatment schemes, Water Talk welcomed Jim Lauria, Vice President of Sales and Marketing at Mazzei Injector Company, and Ben Kuhnel, Senior Project Manager for Arcadis. Learn how ozone works in concert with other processes to safely recycle water and treat contaminants of emerging concern — even in mobile/on-site applications.
Steve Katz, Market Development Manager at SUEZ, explains how water reuse is being looked at differently today than it was even five years ago. Meanwhile, the stresses on water supply — increasing demand from industry and population growth, often in the face of drought — become more pressing with each passing year. Fortunately, water reuse is on the rise as public perception shifts and treatment technology advances.
The adoption of water reuse can be unavoidable due to water scarcity, but it may also be a choice. And when it comes to choices, cost is usually a deciding factor. Gary Hunter, Senior Wastewater Process Engineer with Black & Veatch, helps make sense of the dollars required for recycled water schemes in this Water Talk interview.
Want to hear some good news on water reuse? Listen to this Water Talk interview with Christina Brown, Director of Program Management at Brown and Caldwell, to learn about the EchoWater project, which will allow the Sacramento Regional County Sanitation District — the largest inland discharger west of the Mississippi — to reuse half of their discharge while also reducing nitrogen loading into the Sacramento River.
