Bromate free disinfection by high voltage pulse

Chang I-S, Hoseo University, KR

We designed and assembled high voltaged pulse generating system in our laboratory. The HVI system is consisted of power supply, high voltage generator, capacitors and impulse generator. The impulse with 10 to 20 kV/cm of [...]

Metals disinfection of E. coli in synthetic groundwater and effects of varying water chemistry

Edokpayi J.N., Singh R., Odiyo J.O., Smith J.A., University of Venda, ZA

The sustainable access to clean and safe drinking water remains as global challenge as large numbers of people still consume water that is not safe. Diarrhea; a preventable waterborne disease remains the major cause of [...]

Ag/Ag3PO4-doped BiPO4 heterostructures and their photocatalytic applications under visible light irradiation

Chen Y.J., Tseng C.-S., Tseng P.-J., Huang C.W., Tseng C.-S., Tseng P.-J., Wu M.-Y., Wu T.H., Lai C.-Y., Wu M.-Y., Wu T.H., Lin Y-W, National Changhua University of Education, TW

Ag/Ag3PO4-doped BiPO4 (Ag/Ag3PO4/BiPO4) heterostructures were synthesized by the hydrothermal method combined with the sonochemical process. Powder X-ray diffractometry, UV–Vis diffuse reflectance spectroscopy, Raman spectroscopy, and transmission electron microscopy were used to characterize the heterostructures. The [...]

Efficiency of Point-of-Use Water Disinfection Using Deep UV Light Emitting Diode Technology

Gaska I., Gaska R., Bilenko O., Bilenko Y., Shturm I., Bilenko O., Bilenko Y., Shatalov M., Gaska I., Gaska R., Sensor Electronic Technology, Inc., US

We present results of microbial disinfection of E.coli bacteria in water using Point-of-Use UV light-emitting diode (LED) chamber. A set of four UVCLEAN LED lamps was used to produce UV radiation at 272-273nm. More than [...]
