Church Road Transfer Station - Modular MBR Wastewater Treatment Plant

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.

MABR: Familiar WWTP Principles, Better Results

Wastewater treatment plant (WWTP) designers and decision-makers tasked with finding more cost-effective performance for challenging applications want new options. Here is how flat-sheet membrane aerated biofilm reactor (MABR) technology tweaks the chemical and biological functions of conventional activated sludge (CAS) processes to reduce energy consumption and operating expenses (OPEX) in demanding applications.

The Root Of The Problem: How Trees Affect Our Sewers

In this article, explore how tree roots grow and how they impact our sewer systems.

More Water At The Lower Cost: A Revolution In RO Technology

This white paper will explore how the BiTurbo, a revolution in high recovery RO, optimizes membrane performance and reduces total cost of water. 

Advances In UV Disinfection For Wastewater Tertiary Treatment In Open Channels

Meeting modern water reuse goals requires moving past legacy disinfection. Advances in UV technology now provide chemical-free, reliable pathogen inactivation for even high-flow, open-channel tertiary treatment.

Clean Water Even During Disaster: Why U.S. Pipe Ductile Iron Pipe Is The Smart Choice For Public Health And Safety

Infrastructure must endure disasters to protect public health. Learn why ductile iron pipe offers fire resistance, seismic stability, and ensures clean, chemical-free water delivery when it is needed most.

A New Era In Blower Control Efficiency

A common misconception among wastewater plant managers is that pressure-based blower controls remain an industry “best practice” for aeration. The problem is this approach was developed during an age when most blowers were constant speed machines with outputs that could only be governed by the manipulation of inlet valve position or header pressure. Newer self-tuning, airflow-based control systems save energy, improve effluent, and reduce greenhouse gas emissions.

Anammox Sidestream Deammonification Process Allows Plant To Reduce Capital And Infrastructure Costs

Pierce County’s main goal was to reduce the discharge of nitrogen to Puget Sound while also reducing plant operating costs while in nitrogen removal mode. After upgrading, the new system continues to remove greater than 80 percent of ammonia and 75 percent of total inorganic nitrogen, equating to a reduction of over 400 tons per year of nitrogen loading to Puget Sound.

Self-Sufficient WRRF Completes In-House Grit Removal Upgrade

Aging, inefficient aerated grit facilities at North Davis Sewer District’s (NDSD) treatment plant headworks not surprisingly caused the typical headaches of poorly performing headworks:  downstream process tanks filled with grit and process equipment wore much faster than it should. And not surprisingly, it became a costly hassle for plant staff with annual basin cleanouts.

Acoustic Inspection Helps Campbell River Optimize Inspection Program

In this case study, explore how incorporating the SL-RAT into their maintenance program has realized significant savings for the city of Campbell River.

Determination Of EN15662:2008 - Determination Of Pesticide Residue In Food Of Plant Origin, By An Automated QuEChERS Solution

Pesticide residue laboratories are required to undertake analyses of an ever increasing number of samples. The analyses typically involve use of multi-residue methods (both GC-MS and LC-MS) to test for over 500 pesticide residues.

The Active Control Program For Advanced UV Oxidation

This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

Analyzing Total Organic Carbon In Sea Water

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.

What Are You Doing To My Pipe: Can PVC Pipe Be Loaded?

The argument has been used that PVC pipe is delicate and can’t be subjected to any kind of loading. In EBAA's years of testing we have found that is not the case at all. PVC can take an extreme amount of strain.

Dosing Of Sodium Hypochlorite Solution For Drinking Water Disinfection

A water purveyor was in urgent need of a chemically resistant flow instrumentation with a long life of service that allowed reliable and long-term stable dosing of the sodium hypochlorite solution.

Environmental Applications Of The Agilent 1290 Infinity UHPLC: The Evolution Of Chromatography This application note presents examples of the use of UHPLC (ultrahigh performance liquid chromatography) for environmental applications using the new Agilent 1290 Infinity LC. By E. Michael Thurman and Imma Ferrer Center for Environmental Mass Spectrometry Department of Environmental Engineering University of Colorado Boulder, CO, USA

Advances In Paper-Based Devices For Water Quality Analysis

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.

Combining Decentralized And Centralized Wastewater Treatment Strategies To Solve Community Challenges

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. 

Sewage Pump Station Level Application

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.
