There are many different types of conveyance technologies, including sluices, screw conveyors, belt conveyors, and more. The right technology for an application depends on a vast number of factors.

A large treatment plant includes several treatment processes that contribute to providing quality recycled water pursuant to the state of California Title 22 regulations. Major treatment processes include raw wastewater pumping, preliminary treatment, primary treatment, secondary treatment, tertiary treatment with Parkson DynaSand® filters, and disinfection.

Among the pump stations managed by Branford, CT, is a long-term problematic station located at Burban Street. There were two primary problems at this station: 1) clogging from modern day trash and raggy, stringy materials, and 2) fats, oils, and grease (FOG) from a nearby nursing home and restaurants, which accumulate and float on the water surface, resulting in a horrendous mess.

Ozonation and biologically active filtration (O3-BAF) is being increasingly used to address the issue of organic micropollutants (OMPs) in wastewater treatment and potable reuse.

The Abbottstown-Paradise Joint Sewer Authority was incorporated in 1973 and utilized a continuous flow activated sludge system with an average daily design flow of 0.21 MGD. At that time the plant was only required to reduce total suspended solids (TSS) and effuent ammonia to required levels to serve the area population of about 2000. Due to urban growth and increased storm flow runoffs, the plant was in need of an expansion and upgrade by the late 1990s. 

The City of Marengo, Illinois operates an activated sludge wastewater treatment plant that processes an average volume of 1.8MGD with a maximum capacity of 5.94MGD. In the fall of 2007, the operators of the plant began to observe reduced performance of their liquid-polymer feed system that was in place at the city’s facility. The Dynablend™ liquid-polymer unit was a good fit for the Marengo plant because of its reliability and performance over a wide range of polymers commonly used for sludge processing.

The AnoxKaldnes™ MBBR (Moving Bed Biofilm Reactor) process is a biological wastewater treatment process that utilizes specialized plastic carriers to create a surface on which a biofilm can attach.

In this case study, read about a community-owned utility that partnered with AMERICAN to provide 53,000 feet of ductile iron pipe for a new water reclamation facility. 

Like so much of America’s infrastructure, our wastewater infrastructure is aging and inadequate. Like our highways and bridges, our wastewater infrastructure needs improvement. How do we solve this problem?

Read about the Santa Clara Regional Wastewater Facility, which is home to several Eclipse Pumps providing chemical dosing to municipal wastewater.

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.

This application note explores Sequencing Batch Reactor (SBR) systems that have been installed worldwide in a variety of applications, ranging from a few gallons per minute (GPM) to thousands of GPM.

A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

The textile industry is a water consumption intensive industry. Water is utilized for cleaning the raw material, and for the different steps in the textile dyeing process. Due to the effects of water scarcity and stricter environmental regulations, the cost of fresh water utilization has increased worldwide.

The need for of nitrogen-reducing wastewater treatment systems has become more common in the past few decades due to various environmental concerns, including eutrophication, oxygen depletion, and toxicity to aquatic organisms in lakes and streams. The addition of nitrogen removal to any wastewater treatment plant, new or existing, typically increases the costs of the project significantly. When evaluating suitable technologies, it becomes critical to properly identify processes that can not only proved the best upfront capital value but also provide the most sustainable long-term functionality.

Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

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

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.

Learn about filtering microplastics from industrial wastewater prior to discharge, and how this is one way to effectively reduce the volume of this waste material from entering our surface water.
