Cyanotoxins are toxic substances produced by cyanobacteria, or blue-green algae, which can proliferate in water bodies under conditions like high nutrient levels and warm temperatures. There are over 1,118 different cyanotoxins identified globally in freshwater environments across 66 countries, illustrating the widespread nature of this ...
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 ...

Enzyme engineering is a scientific technology that puts enzymes or microbial cells, animal and plant cells, organelles, etc. in a certain biological reaction device, and then use the biocatalytic function of the enzyme to transform the corresponding raw materials into useful substances and apply them to social life with the help of engineering means. It includes the preparation of enzyme ...
Researchers have developed a recyclable, adsorbent membrane that gives hope for large-scale treatment When we flush, we expect to never encounter the contents again, but the truth of the matter is that pharmaceuticals dissolved in urine or simply discarded in a toilet, tub, or sink frequently make their way into our drinking water supply and the food chain. The same goes for personal care ...
In this study, we determined the removal of a prototype human norovirus (Norwalk virus, NV) by bench-scale alum coagulation, flocculation and sedimentation processes using reverse transcriptase polymerase chain reaction (RT-PCR) for norovirus assays. After determining optimum conditions for the coagulation, flocculation and sedimentation processes in terms of turbidity reduction, jar tests were ...
It is rarely reported that the interaction between xenobiotics and algae may cause potential water quality risks and affect the drinking water treatment process. ...
One Sunday in May our weekend standby service received a telephone call from a pharmaceutical company who’s waste water treatment system had suffered a plant upset, thought to have occurred the previous day, resulting in the loss of nitrification. The standard to be maintained is 10 mg/l. Because of the urgency of the situation our team traveled to the company that same day taking ...
The Culligan solution allows the facility to use municipal water, treated with a combination of modular water treatment technologies. The solution includes a pre-treatment carbon filter, a reverse osmosis system, a storage system, deionizers, a 0.2 micron filter ond on ultraviolet (UV) unit. ...

Infectivity data are important for assessing public health risks from exposure to human pathogenic viruses in the environment. Here, treatment efficiencies of three (drinking) water treatment processes were estimated by quantification of the indicator virus bacteriophage MS2 with culture and real-time reverse transcription polymerase chain ...
Situation: In 1997, a Zentox ozone cooling water treatment system was specified for water treatment of the hospital’s four 400-ton towers. The medical center, a state-of-theart facility, serves a wide range of patient needs at the Hanover Medical Park in Richmond, Virginia User comment from Phil Vierela, Administrative Director of Facilities: “I’ve had plenty of experience with ...
An estimated 1.1 billion persons worldwide lack access to an improved water source. Hundreds of millions more drink contaminated water from improved sources because of unsafe water treatment and distribution systems and unsafe water storage and handling practices. The health consequences of inadequate water and ...
This can only be achieved in specific situation involving specific frequencies of high ultrasound power (high W•cm-2, high dB) exposed to relatively low liquid volumes of relatively low temperatures. Water Treatment by Means of Ultrasound Among the numerous applications of ultrasound, the approach is used in the field of water ...
