Abstract Water treatment, abundant clay in the area, for elimination of particles and microorganisms wastewater disinfection through alcoholic extract molle, which has a high concentration tannins that acts as germicide, not affecting asparagus during cold washing, saving thousands cubic meters groundwater daily. The study explanatory level experimental design. weekly sample (drinking water, re...

BACKGROUND Needleless valve connectors for vascular catheters are widely used throughout the United States because they reduce the risk of biohazardous injuries from needlesticks and exposure to bloodborne pathogens, such as human immunodeficiency virus and hepatitis C virus. Patients with long-term central venous catheters are at significant risk of acquiring catheter-related bloodstream infec...

Thorough hand disinfection in hospitals is essential to prevent nosocomial infections. Health care workers are trained and instructed on when and how to use hand sanitizers during apprenticeship training and continuing education, but up to now there is no automatic system to give immediate feedback about the quality of a hand disinfection in daily clinical routine. We propose a method that is c...

Cleaning and disinfection of surfaces which have been in contact with animals, poultry or organic material is a vital element in controlling bacterial and viral diseases, and ensuring the wholesomeness and safety of foods. The thoroughness of pre-disinfection cleaning is the most important determinant of the efficacy of disinfection processes. Disinfectant users and officials responsible for th...

Conventional treatment methods are used in the of drinking water to protect human and environmental health. These can be named aeration increase amount oxygen, precipitation, chemical treatment, filtration, chlorination for disinfection. Besides, iron manganese removal operations performed places where hardness is very high depending on geographical location, cases content high. Drinking, techn...

Despite regular disinfection and decontamination of the hospital floors and surfaces, resistant pathogens from the hospital surfaces and their transmission to humans have been reported recently. The resistance of pathogens to the disinfectant agents or failed disinfection techniques have put the routine floor and non-critical surface disinfection done in hospitals into question with regard to t...

To the best of our knowledge, there was little information available on pathogen removal using low level disinfectant followed by free chlorine in sequential disinfection (SD). This study investigated Escherichia coli inactivation by four types of disinfection: single step disinfection (SSD), SD, traditional sequential disinfection (TSD) and mixed disinfectant disinfection (MDD). Results indica...

Disinfection by-products were determined in 15 water treatment plants in Beijing City. The effects of different water sources (surface water source, mixture water source and ground water source), seasonal variation and spatial variation were examined. Trihalomethanes and haloacetic acids were the major disinfection by-products found in all treated water samples, which accounted for 42.6% and 38...

STATEMENT OF PROBLEM Disinfection of prostheses with chemical solutions has deleterious effects on dentures. The appropriate power setting of microwave for disinfection, without affecting denture base properties, is a controversy. PURPOSE To evaluate and compare the effect of simulated microwave disinfection at a recommended power setting on the mechanical properties of three denture base hea...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) has been shown to survive on ambient surfaces for extended periods of time. Leftover MRSA environmental contamination in a hospital room places future patients at risk. Manual disinfection supplemented by pulsed xenon ultraviolet (PX-UV) light disinfection has been shown to greatly decrease the MRSA bioburden in hospital rooms. Howev...
