Data from facility fogging trials conducted in collaboration with University of California, Davis, EC99 antimicrobial comparisons published in Postharvest Biology and Technology, and apple studies demonstrating Listeria monocytogenes reduction and cross-contamination prevention are examined to illustrate the difference between residue removal and structural ...
Infection remains the leading cause of revision surgeries, and with the increasing number of total joint arthroplasty (TJA) procedures year over year, effective infection control has never been more critical.1,2 One solution to reducing the risk of these complications is the use of surgical irrigation, designed to remove microbial contamination from the tissues ...
Click here to learn about: Candle Filter vs Cartridge Filter Types of Cartridge Filters There are different types of cartridge filters, each designed to remove specific contaminants. The most common types are: ? Sediment Filters – Focus on removing large particles and debris. ? ...
Fuel polishing is a process that involves filtering and purifying stored fuel to remove contaminants, water, and sediments that may have accumulated over time. It is commonly used for diesel fuel and other types of stored fuels to ensure their quality, maintain optimal performance, and prevent damage to engines or ...
Groundwater contamination is a significant environmental challenge faced by many regions worldwide. Pollution resulting from hydrocarbons and other contaminants can have disastrous consequences on both the environment and human health. Therefore, the need for effective groundwater remediation methods cannot be overemphasized. In this article, we will discuss some of the groundwater remediation ...
A recent study investigated the use of natural zeolite as a microbial support media in wastewater treatment. Using scanning electron microscopy (SEM), and other techniques, a team of researchers in Romania has concluded that natural clinoptilolite zeolite acts as an absorbent for pollutants and as a support material for the colonization of microbial ...
Sludge drying uses heat energy to evaporate water, greatly reducing sludge volume, storage and disposal costs, and removing pathogens. Due to microbial cracking, hydrolysis of macromolecular organic matter such as fat and protein and release of volatile substances in the drying process, the sewage contains a large amount of ammonia nitrogen, volatile organic ...
It can be used to remove phosphorus, lead and hexavalent chromium in wastewater treatment. ...
To explore the availability of native microbes and activated sludge for ammonium removal, the native microbes and activated sludge in Jialu River basin were investigated in terms of ammonium-removing activities and their microbial communities using spectrophotometry and high-throughput sequencing. ...
The use of microbial biomass as biosorbent for phenol removal has been extensively studied, but its removal by biosorption by thermophilic cyanobacterium Phormidium sp. has not been investigated to the best of our knowledge. In the present study, some important parameters for biosorption process were optimized, starting with testing the ...
Biodegradation of anionic surfactants, like sodium dodecyl sulfate (SDS) are challenged by some bacteria through the function of the enzyme alkyl sulfatases. Therefore, identifying and characterizing bacteria capable of degrading SDS with high alkyl sulfatase enzyme activity are pivotal. In this study, bacteria isolated from surfactant contaminated river water were screened for their ...
This study aimed to investigate the organic removal efficiency and microbial population dynamics in activated sludge with pressurized aeration. ...
The present study evaluated volcanic pumice stone as a suitable media for biological growth and biofilm development in a fixed-bed sequencing batch reactor (FBSBR) for atrazine removal from aquatic environments. The FBSBR was fed with synthetic wastewater containing sucrose and atrazine at four hydraulic retention times to assess biodegradation of atrazine by a ...
EP was found to be a significant process in removing soluble microbial products from the membrane surface, resulting in an increase in permeate flux as the filtration progressed. ...
The effect of ambient temperature on the ability of the BSF to remove microbes from water is unclear. Model filters were distributed among different temperature-controlled laboratories and dosed daily with surface water amended with sewage. Comparison of the total coliform and Escherichia coli counts in the influent versus effluent revealed an immediate drop in the ...
This work describes the nutrient removal performance and microbial characteristics of a full-scale integrated fixed-film activated sludge-enhanced biological phosphorus removal (IFAS-EBPR) process for municipal wastewater treatment. ...
The current investigation reports the effect of cathode electron acceptors on simultaneous sulfide and nitrate removal in two-chamber microbial fuel cells (MFCs). Potassium permanganate and potassium ferricyanide were common cathode electron acceptors and evaluated for substrate removal and electricity generation. ...
This allowed the determination of a 95th percentile of reference pathogen numbers in stormwater (2 n/L for adenoviruses, 1.4 n/L for Cryptosporidium and 11 n/L for Campylobacter) and was used in a quantitative microbial risk assessment to determine the required microbial inactivation targets. Log10 removals through treatments and/or control ...
The effects of synthetic wastewater that contained 20 mg/L Cu(II) on the removal of organic pollutants in a sequencing batch reactor were investigated. Results of continuous 20 mg/L Cu(II) exposure for 120 days demonstrated that the chemical oxygen demand (COD) removal efficiency decreased to 42% initially, followed by a subsequent gradual recovery, which ...
The collaborative and mutually reinforcing phosphorus removal in domestic wastewater in a sponge iron and microorganisms system was studied through a laboratory and a pilot scale experiment. ...
