This is the third installment of a three-part series exploring headworks screening problems and solutions. In this installment we will explore solids removal options for headworks facilities.
A natural gas-fired combined cycle power generation facility located in Idaho contacted QUA to find a solution to improve the performance of a water treatment system used to recycle the plant’s cooling tower blow down water.
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product puriﬁcation needs, ﬁnd alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and proﬁtably.
The 1.5 MGD West Carrollton Wastewater Treatment Plant in West Carrollton, OH came on-line in 1989 and today serves 12,000 area residents. The activated sludge facility produces an average of 200 wet tons/month of sludge that, following belt filter press dewatering, is spread on area farmland by a biosolids management company.
The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.
Clearas Water Recovery's patented treatment platform, Advanced Biological Nutrient Recovery (ABNR) technology, is highly modular and scalable, providing a sustainable approach to cleaning water. The Clearas system consists of three core phases: the blend phase, the nutrients recovery phase and the separation phase. For optimal results, Clearas has partnered with Endress+Hauser for dependable products and reliable technical expertise.
AdEdge Water Technologies was recently engaged by Pharmaceutical Services & Installations (PSI) to provide a treatment option for the Century Packaging Corporation in Las Piedras, Puerto Rico.
La Crosse’s WWTP wanted to make some improvements to their treatment processes to make their plant more efficient and effective. Because of the odor, hazardous nature, and sheer weight of the organics-laden grit, La Crosse’s disposal fees were quite significant.
Greer Commission of Public Works (CPW) has been providing water, wastewater and electric services to the City since 1914 with natural gas service added in 1957.
The district manager for the Pinetop-Lakeside Sanitary District (AZ) reports that a special gas chlorination system, featuring unique components and controls, and manufacturer-supplied service, has effectively replaced a chlorine tablet system.
A plant’s headworks plays a crucial role in the pretreatment influent for any wastewater treatment facility. They protect the operation of downstream equipment and enhance the efficiency of the overall wastewater treatment process.
The clarity of water in a stream, river or ocean is a key determinant in fostering a healthy and balanced aquatic ecosystem. The clearer the water, the greater the ability of light to penetrate to aquatic plants which generate the oxygen needed for aquatic life.
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.
Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.
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.
QuEChERS is a Quick-Easy-Cheap-Effective-Rugged-Safe extraction method that has been developed for the determination of pesticide residues in agricultural commodities.
Many food processors use dissolved air flotation (DAF) to remove fats, oils and grease (FOG) and suspended solids from their wastewater streams.
Though they all must support routing functionality, some devices do it better than others.
Routing consumes more energy, so the lifetime of the battery will be affected. Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.
Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.
While several case studies demonstrate that participation in water quality trading markets can have dramatic economic benefits, relatively few communities participate. The U.S. EPA and USDA teamed up to find out why, hoping to increase participation.
Unlike dead-head filtration characterized by a single flow in and out, both reverse osmosis (RO) and nanofiltration (NF) technologies are unique in that they produce two effluent streams, a lower TDS (total dissolved solids) permeate and a higher TDS concentrate.
A Kenosha, WI wastewater treatment plant leveraged innovative upgrades to become more sustainable — and save $750,000 per year.
Yes, America cleaned up at the Olympics this summer, but how does the U.S. fare on the world stage when it comes to water resiliency, efficiency, and quality?
I was at a funeral recently and when the internment got to the “ashes to ashes, dust to dust” part, specifically at “dust you are and to dust you shall return,” it occurred to me that nothing could be further from the truth.
Wastewater facilities have transitioned from “sewage treatment” to “wastewater treatment”, then to “water reclamation”, and now have progressed toward “water resource recovery facilities” (WRRFs).
