The Church Road Transfer Station (CRTS) is located southwest of downtown Parksville, British Columbia in the Regional District of Nanaimo (RDN). The facility receives organic waste, solid waste, recyclables, and construction/demolition waste from the general public and commercial haulers. Its expansion under the RDN’s Green Building Policy transformed it into a zero-waste facility.

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.

Union Township, New Jersey was having a lot of trouble with their pump station. Although a small pump station, it was extremely cumbersome to maintain. The station was using a trash basket with a ladder and rail system to screen solids. This was extremely time-consuming, used an excess of manpower and proved to be ineffective at times. They knew they needed a better solution.

Read about one of the largest wastewater treatment plants in the world that recently finished a project for upgrading its sludge valve actuators.

In 2007, Greenville, SC-based Western Carolina Regional Sewer Authority (WCRSA) conducted a rigorous performance test on a new tertiary treatment technology to assess its ability to effectively remove nitrate-nitrogen (NO3-N) without using excess amounts of methanol at its Lower Reedy Wastewater Treatment Plant (WWTP).

The Portland, Indiana, Wastewater Treatment Plant (WWTP) had been using six granular-media filter units for tertiary treatment since the 1980s. The plant’s treatment protocol includes fine screens for grit removal, followed by primary clarifiers, trickling filters, aeration basins, secondary clarifiers, the tertiary treatment system, and then chlorine disinfection.

Hydra-Stop’s insertion valve provides targeted control to allow the city to bring down the levels of iron and other particulates in their water distribution system.

It’s a scenario that is becoming more common at food and beverage facilities. The introduction of a new product to market, or a boom in sales of an existing product, prompts management to increase production capacity. While there is plenty of space for production equipment, the corresponding need for additional wastewater treatment capacity may not be readily accommodated.

Sturbridge, Massachusetts historically suffered from periodic blooms of filamentous bacteria that caused bulking in the secondary clarifiers of their three activated sludge package plants.

Comparing blower performances across different manufacturers and technologies has long been a difficult task. For many years, it was all too easy to present data that, although accurate, was potentially misleading. Manufacturers were selective about what information they published as well as what conditions they chose to specify performance. The result was a numbers game the buyer frequently lost. Fortunately, the Compressed Air and Gas Institute (CAGI), in cooperation with its members, has developed a tool for a fair comparison between blowers.

Of particular interest when it comes to bridges is the locating of pressurized water lines on and under bridge structures. Pressurized pipelines can present a number of unique challenges to the design engineer and utility owner.

The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.

Lack of sufficient straight pipe run made it impossible to successfully apply the preferred magnetic flow meter (magmeter) to accurately measure the flow of raw sewage.

Learn how a wastewater treatment plant in eastern Switzerland relies on the targeted use of flocculants to prevent sludge washout. 

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.

Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

Explore how additional costs for analytical conductivity measurement can be eliminated.
