Location: Al-Hayat Pharmaceutical Manufacturing Company, Jeddah, Saudi Arabia Background: Al-Hayat Pharmaceutical is an old manufacturing facility that was built in 1972. This company produces the following range of products: Antibiotics: (syrup & tablet) including Ciprofloxacin (broad-spectrum) Clindamycin (gram-positive) Ampicillin (broad spectrum) Anti-diarrheal product (syrup) a ...
Removal of API’s, EC’s & EDC’s via Nyex Rosalox™ Technology We recently discussed the removal of active pharmaceutical ingredients (API’s) and emerging contaminants (EC’s) in the environment – see Removal of Active Pharmaceutical Ingredients from Water . Endocrine Disrupting Chemicals (EDCs) is another category of compounds whose presence in the ...

Wastewater & COVID-19 Connections When the word wastewater crosses your mind, there is probably also a memory of your Mom’s voice telling you – wash your hands! When humans transitioned into community living, keeping your living space separate from your bathroom space was an important rule to learn. We can thank early scientists who were curious about how diseases spread and ...
Among its many applications and due to its strong oxidizing character, it stands out especially for being a compound widely used in water purification in WWTPs (wastewater treatment plants) and as a disinfectant in other applications. ...
Pharmaceuticals and their metabolites are detected on an increasing scale in the aquatic environment. The pharmaceuticals (such as drugs) mostly get into the surface and drinking water through the excretions of humans and animals; however, the wastewater of pharmaceutical production facilities can also be contaminated with active ingredients. The production of pharmaceuticals takes place in two ...
This involves adding ozone to the wastewater so that the active ingredients (Capecitabin and Mycophenolatmofetil) oxidise. The process was developed by EnviroChemie on a laboratory scale using original substances, and subsequently implemented on a large scale. Requirements of the wastewater treatment plant to be created: Reliable results, ...
But aren’t PPCPs removed at a wastewater treatment plant? Unfortunately, conventional sewage treatment methods cannot thoroughly remove many PPCPs. ...
Levels of triclosan within the wastewater treatment plant (WWTP) ranged between 0.026 and 1.488 ppb. Triclosan concentrations were reduced by the WWTP, but small concentrations enter receiving freshwater bodies. ...
On average, there was about one ARG able to trigger resistance in each bacterial cell examined. ARGs in Wastewater A previous study found bacteria with an ARG tied to severe infections may be spreading through wastewater treatment plants in northern China. ...
After rain events in densely populated areas, combined sewer overflows (CSOs) can have severe health-related effects upon surface water quality, as well as diffuse overland runoff and wastewater treatment plants (WWTPs). All of these sources emit pathogens and fecal indicator bacteria into the surface water, which the EU Bathing Water Directive addresses by ...
In many coastal watersheds and ecosystems, rivers discharging to estuaries receive waters from domestic wastewater treatment plants resulting in the release and distribution of pharmaceuticals to the marine environment. ...
Beneficial bacteria are a natural solution for improving water quality in ponds, lakes, reservoirs, and canals. Beneficial microorganisms that are naturally present in the aquatic environment are typically at low levels, so they work much slower at reducing nutrients to maintain water quality. Aquatron and Waste and Sludge Reducer contains two billion bacteria per gram. At this elevated ...
In the present study, bioaccumulation of select pharmaceuticals and other contaminants of emerging concern was examined in fish from Buffalo Bayou, a tidally influenced urban ecosystem that receives effluent from a major (∼200 million gallons per day) municipal wastewater treatment plant in Houston, Texas, USA. Using isotope dilution liquid chromatography–tandem ...
Abstract This study describes the development of a bioassay to detect the presence of progesterone and progesterone-like molecules in wastewater samples. The basis of the bioassay is the integration of the human progesterone receptor gene into the yeast Arxula adeninivorans for the constitutive synthesis of the receptor. ...
Pharmaceuticals and personal care products (PPCPs) are emerging contaminants that have been found ubiquitously in wastewater and surface waters around the world. A major source of these compounds is incomplete metabolism in humans and subsequent excretion in human waste, resulting in discharge into surface waters by wastewater treatment plant ...
The environment is likely to play an important role in dissemination of antibiotic resistance genes (ARGs) among both environmental and pathogenic bacteria. Wastewater treatment plants (WWTPs) accumulate both chemical and biological waste from the surrounding urban milieu and have therefore been viewed as potential hotspots for dissemination and development of ...
Changes in the endocrine potency of municipal wastewater at 3 wastewater treatment plants (WWTPs) in Australia were investigated using a panel of in vitro receptor‐driven transactivation assays. ...
Surface water samples used for irrigation or domestic purposes, and water samples from the outflow of wastewater plants were collected from six provinces. Viruses were recovered from the samples using a glass wool adsorption-elution method and then further concentrated using polyethylene glycol/sodium chloride precipitation. ...
These data are among the first measurements of PPCPs and PFASs in marine sediments from the Pacific Northwest and provide a comparison to previous measurements of these chemicals in influent, effluent, and biosolids from municipal wastewater treatment plants throughout the region. The concentrations of both PPCPs and PFASs in sediments from Puget Sound and ...
This work focused on the study of the types of heavy–metal–resistant anaerobic bacteria from the sludge of a brewery wastewater treatment plant exposed to high concentrations of dissolved Cd (II), Cu (II) and Zn (II). ...
