Church Road Transfer Station - Modular MBR Wastewater Treatment Plant
5/28/2019
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.

Ontario - Modular MBR Sewage Treatment Plant
5/18/2019
The Detour Lake deposit is Canada’s largest undeveloped pure gold reserve, and is located approximately eight kilometers west of the Ontario-Québec border, 180 kilometers northeast of Cochrane, Ontario. Gold production at the site began in early 2013 and production at the mine is expected to grow over time.

Design And Care Of Reverse Osmosis Systems, Part 3: Operation And Monitoring
2/5/2019
Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices.

Is A Containerized Treatment System Right For You?
1/24/2019
As industrial facilities continually look for ways to reduce capital costs and decrease installation timelines associated with water treatment and other systems, the practice of containerizing equipment has become more prevalent. A containerized system offers many benefits of lower costs than comparable field erected buildings, faster timelines, and lower field installation requirements.

Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment
1/14/2019
The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

Savings Helps MABRs Gain Traction In Municipalities
5/9/2018
An MABR is essentially a biological wastewater treatment process that utilizes seemingly passive aeration through oxygen-permeable membranes. Oxygen transfer through the MABR membranes is diffusion based: driven by concentration differences such that oxygen passes from air at atmospheric pressure into water at a higher hydrostatic pressure. This oxygen transfer mechanism, wherein air is supplied to the process at very low pressure, is the reason MABRs have significantly lower energy consumption compared to other wastewater treatment processes, such as conventional activated sludge (CAS), that utilize diffusers. This energy savings is one of the key reasons MABRs are gaining traction in the municipal wastewater industry.

Membrane Technologies In Containerized Units Allow For Installation In A Small Footprint
4/23/2018
After an international tender process, the Israel Electric Company (IEC) chose Fluence to design, manufacture, and supply containerized ultrapure water production systems for use as makeup water for heat-recovery steam generators (HRSG) and for NOx emission reduction at recently upgraded power plants across Israel. More than 15 units of 20 m3/h production modules, each fitted in two 40-foot shipping containers, were provided to seven power plants. Their compact design allowed for ease of installation, operation, and maintenance while meeting the customer’s demanding engineering standards.

Addressing Fouling Challenges In Water Treatment With RO Membrane
4/18/2018
Reverse osmosis (RO) membranes are widely used in potable water, wastewater, and industrial applications. However, a major issue in the application of RO membrane technology for desalination and wastewater reclamation is membrane fouling. It limits operating flux, decreases water production, and increases power consumption. Membrane fouling also increases the need for RO plants to perform periodical membrane CIP procedure. These problems decrease process efficiency, increase operation cost, and raise environmental issues related to the CIP solutions disposal.
