As a bulk emergency chlorine vapor scrubber system approached the end of its anticipated 20-year useful life, the city engaged Integrity Municipal Systems, LLC (IMS) inspected the equipment and proposed a system refurbishment plan that would ensure proper system performance and safe storage of the 30,000 gallons of corrosive caustic soda contained within it.
BCR Environmental utilizes the Huber Technology S-Disc thickener in their sludge neutralization process. Because the system is both simple and reliable they chose to standardize on the S-Disc. The design of the technology enables the operators easy access to monitor their process. Read how BCR is putting the S-Disc to work.
Pumps are all too frequently one of the most overlooked and abused pieces of equipment in process automation, yet nothing moves without them and a process becomes inefficient when they don’t operate properly or completely shutdown.

In 2002, Georgia’s City of Flowery Branch faced strict new requirements about discharging water back into nearby Lake Lanier, a community drinking water source, compelling the city to find an alternative wastewater system. After a thorough evaluation of various wastewater treatment solutions, Pall Corporation’s Aria FLEX membrane system was selected due to its critical ability to meet the phosphorus limits.
The City of Greater Sudbury is located 390 kilometers (242 miles) north of Toronto and is the seventh largest municipality (by area) in Canada.
At a water treatment plant that provides drinking water for distribution to a large area of customers, a contractor decided to switch to SITRANS FM MAG 5100W flowmeters. A local representative saved a the contractor time and money by recognizing the need for the magmeter to be isolated from the piping protection before startup, which also saved the customer from added downtime.
A natural gas-fired combined cycle power generation facility located in Idaho contacted QUA to find a solution to improve the performance of a water treatment system used to recycle the plant’s cooling tower blow down water.
With environmental regulations continuing to restrict the discharge of phosphorus from wastewater treatment facilities, traditional methods of phosphorus removal are proving inadequate.
The Gainesville Renewable Energy Center is a nominal 100 MW wood-fired biomass power generation facility located in Gainesville, FL. The plant provides about 30% of Gainesville Regional Utilities’ power, reducing the area’s dependence on energy from fossil fuels and greenhouse gas emissions. The client contacted QUA to install their Q-SEP® UF membranes as pretreatment for the plant’s water treatment system.
The full-scale advanced treatment system takes filtered secondary effluent from the neighboring OCSD treatment plant and converts it to water that exceeds all drinking water quality standards. The 70 million gallon per day (MGD) system consists of microfiltration (MF), reverse osmosis (RO), and the TrojanUVPhox™ UV-oxidation/disinfection system.
A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
Semiconductor manufacturers increasingly want precise control of O2 and N2 concentrations in ultrapure water. Specifically, the polishing loop of a semiconductor plant needs to control dissolved O2 to low levels of 1 ppb or 5 ppb while simultaneously controlling the dissolved N2 between 8–12 ppm.
Hot Clean-In-Place (CIP) sanitization is commonly used to combat microbial growth in the pharmaceutical and food and beverage industries. Performed frequently as a prevention strategy, hot water sanitization is a requirement for high purity water (HPW) for United States Pharmacopeia (USP) and European Pharmacopoeia (Ph. Eur.).
Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.
In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.
The Moundsville Wastewater Treatment Plant in West Virginia chooses not to fix a broken blower unit, but rather to correct an outdated approach. The result is a savings of $50-60K a year in energy costs.
Rising energy prices have made accurate energy measurement a hot topic in recent decades. The need for accurate measurement technologies extends to many different application areas, including heating and cooling; compressed air; steam production and distribution; heavy fuel oil consumption; energy monitoring; and custody transfer. In response, new technology is being developed that integrates tasks previously requiring several measurement devices.
The NEOSEP® MBR system features Kruger’s uniquely designed K-120C and K-240C flat sheet membrane modules. The modules offer several innovative design features that enhance ease of installation, operation and maintenance. This includes an integrated central lifting eye, offering an incredibly well balanced module that makes installation and retrieval a simple and stress-free process.
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.
The need for private partnership in wastewater management has been evident for some time. As a result, there are a number of ways that private players are now involved in wastewater management. For instance, there are plant management specialists, collecting specialists, and technical specialists.
Membrane bioreactor (MBR) plants are found all around the world, serving as a go-to method for treating wastewater through a combination of processes. But as this technology gains popularity, operations must contend with the inherent aeration problems it presents.
As sweater weather approaches, it’s a good time to revisit a USGS report from last year highlighting the importance of leaf removal for keeping phosphorus and nitrogen out of urban stormwater.
Estimates of what it will cost to address the destruction wreaked by Hurricane Harvey are projected to be somewhere in the range of $160 billion, with work that will be required in Texas accounting for most of that total. That’s more than the total cost of Hurricane Katrina and Superstorm Sandy combined. Texas is now officially the new "hot spot" for government contracting of almost every imaginable type.
Research from the UK has identified a “supermolecule” capable of seeking out and eliminating trace pharmaceuticals that contaminate water supplies.
A new study led by researchers with Colorado School of Mines exposes limitations with the current methods used to detect chemicals in oilfield wastewater and offers solutions to help regulators make better decisions for managing this waste stream.
