This paper helps to understand the efficacy of BakerCorp Electrocoagulation (EC) technology and treatment process in treating selenium-contaminated mine effluent. Two mine effluent samples were treated by baker EC. Selenium constituent concentrations in both water samples were reduced significantly to below reporting qualification limits. Based on the results of the effluent samples, electrocoagulation is an effective treatment option for waste streams found to contain selenium.

A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.
By incorporating Membrana UF and Gas Transfer Membrane (GTM) a resort customer was able to reduce the risk of contaminating its cooling water and protect other system components from corrosion. The compact systems exceeded performance expectations and reduced maintenance and operating costs while maximizing the available space.
The role of various bacteria in the destruction of concrete in wastewater systems has been recognized since 1945. Already susceptible to old age, wastewater infrastructure systems are also threatened by corrosive bacteria — but they needn't be. By Heather Ramsey, John Davis, and Gary Hall
With diminished rainfall, a depleted aquifer basin, near-empty recharge ponds, and an earthquake-vulnerable aqueduct system, the Santa Clara Valley Water District (SCVWD) in San Jose, CA, required additional water supplies to maintain regional economic vitality for its growing community.
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.
Packaged Wastewater Treatment Plants offer many advantages, flexibility notwithstanding. One plant in particular, located in Georgia, needed to be upgraded to handle the increased flows from a growing city and to address new effluent discharge regulations. The tight plant site offered minimal opportunity for routine expansion of the packaged wastewater plant volumes, hence special designs were needed. Learn how this 200,000 GPD system is thriving.
The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.

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.
UV disinfection systems disinfect water using UV light at the 254 nm wavelength. UV light at this wavelength actually destroys the DNA of microbiological material in the water which prevents dangerous viruses such as cryptosporidium and e-coli from reproducing and causing harm.
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.
Radar technology is often viewed as the “best” method of level measurement, but this isn’t necessarily true in the water industry.
The oil and gas industry has utilized various deaeration technologies for many years to remove dissolved gases, particularly oxygen, from injection water. In many hydrocarbon recovery and water processes, degassing is necessary in order to minimize environmental impact, improve operating efficiency, avoid process issues and help protect system components.
Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
As interest in biogas grows, more attention is being paid to measuring biogas flow, which has long been a problem area in process measuring technology.
With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.

Supersaturated Dissolved Oxygen for Collection Systems — We employ the world’s most efficient method for dissolving oxygen into wastewater for odor control and corrosion prevention.
Screentec is a mechanical vertical bar screen that can be installed in many applications, including Headworks, Lift Stations, Deep Wells and Manholes. Due to its vertical design, Screentec can retrofit any kind of structure with minimal or no changes.
The Dystor® Digester Gas Holder System is a dome shaped, engineered membrane system that maximizes storage of methane gas and sludge, while also containing odors. Proven in more than 125 installations, the Dystor system provides the highest energy benefits from the anaerobic digestion process.
Capital Controls® new and improved Series FX4000 gas feeders are floor cabinet mounted, vacuum operated and designed to conveniently house a combination of gas feed equipment and controls. The cabinets enclose the gas flow control components and are constructed of ABS with a textured, easily maintained finish.
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.
Atlas Copco's ZS screw blower saves energy in a wastewater treatment plant.
