China has implemented more stringent environmental standards in recent years. Local environmental protection departments now require urban wastewater treatment plants to apply strict enforcement measures to meet effluent discharge standards.

Read about a utility that sought alternate disinfection process options to replace equipment that had reached the end of life. 

Every year, an estimated 10 trillion gallons of untreated stormwater runoff containing raw sewage, fertilizer, oil, pesticides, bacteria and other pollutants enter U.S. streams, rivers and oceans from city sewer systems, polluting the environment and drinking water supplies. In many urban and suburban areas, this runoff also causes significant flooding.

In an industry beleaguered by workforce retirements, costly consent decrees, and climate-induced heavy rainfall events, fresh perspectives and ingenuity are high-profile needs. Fortunately, the U.S. EPA’s  Campus RainWorks Challenge is designed to deliver exactly those benefits from the next generation of stormwater specialists. Here’s how current utilities, municipal planners, and consulting-engineer practices all stand to benefit.

With increased effluent pollution restrictions on municipal wastewater treatment plants, cities are pressed to find ways to economically increase their effluent quality with little to no funding. Many new NPDES permits require the reduction of nitrate and/or phosphorous, as nutrient removal becomes more prevalent due to the effects of nitrogen and phosphorus on discharge receiving streams.

In this follow-up webinar Technical Product Manager, Phil Taylor will demonstrate in more detail how to select and design a Hydro-Brake using our free online design tool. The Hydro-Brake is one device that should be in every stormwater engineer’s toolbox. Hydro invented the vortex valve back in the 1960’s and has led the world in its development and design ever since.

Megalim Solar Power Ltd’s Power Station, located in Israel’s northern Negev desert, will be the first utility-scale solar thermal or concentrated solar power (CSP) plant in operation in Israel when completed. To minimize fresh water usage in the cooling cycle and boiler makeup of the power plant, Fluence designed and supplied a containerized system for treatment of cooling tower blowdown wastewater for reuse and the production of ultrapure water (UPW).

Fluid catalytic cracking (FCC) is a major unit operation in refineries around the world. FCC is used to convert lowvalue, high molecular weight feedstocks such as shale oil, tar sands oil, and coker gas oils into lighter, high-value products by “cracking” C-C bonds.

After spending decades and millions of dollars rehabilitating sewer pipes across its service area, a large coastal utility embarked on a pilot pipe condition assessment program for 25,000 linear feet in areas prone to high unwanted infiltration rates.

Water treatment challenges are never-ending — from source water availability, to seasonal upsets, to new contaminants of emerging concern (CECs). The best way to stay ahead of such issues is to cultivate a pipeline of innovative solution development ready to address the next challenge. Here are some key insights for evaluating suppliers that are best positioned to do exactly that.

Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.

The most common level application in the water and waste water industry is the infamous wet well. With its line-of-sight measurement technology, rugged sensor, narrow laser beam and virtually nonexistent maintenance requirements or on-site calibration, ABB’s LLT100 laser level transmitter answers most concerns related to wet well level measurements and makes it easy to calculate what could amount to a substantial return on investment.

The 2000PV is a restraint for PVC pipe and the standardized mechanical joint. This product is the result of years of testing and evaluation and its performance has been proven by thousands of hours of proof tests, as well as third-party evaluations. This report describes the 2000PV through the 12" size.

To sustain the environment and smart community growth while protecting public health, engineers, municipal health officials, and regulators need innovative wastewater treatment solutions. The latest evolution of decentralized systems can efficiently handle residential and commercial daily flows and are a cost-effective alternative to the large, centralized wastewater treatment plants of the past. 

FLEX-TEND® flexible expansion joints are designed to protect structures and pipelines from differential movement whether this movement is earthquake induced or the gradual motion of soil subsidence. This bulletin offers a concise listing and discussion of the important features and materials of the double and single ball assemblies.

This application profile focuses on two test sites with different treatment requirements and describes how Aqua-Aerobic Systems’ OptiFiber® pile cloth media filtration was used at both sites to address the removal of harmful constituents from refinery wastewater.

Water quality test strips have been around for decades. They are usually constructed from a porous media, including different types of paper, and undergo a color change when dipped into water containing the analyte of interest. These test strips have seen application in swimming pools, aquariums, hot tubs, remediation sites, and other commercial/environmental areas.

As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

The Saalfeld-Rudolfstadt Association in Germany must rely on cutting-edge technologies that optimize flow measurement in order to allow for smooth processes and supply 82,000 inhabitants with clean drinking water.
