Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; Disinfection with chlorine gas, Disinfection with sodium hypochlorite and Disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different Disinfection methods.

The aim of this report is to create an easily accessible guide to basic hygiene, cleaning and Disinfection within the small animal practice. It is based on a literature study, using mainly research from the public health sector, due to the lack of relevant scientific reports within the veterinary field. To prevent the spread of infectious diseases it is important that the staff understands the importance of basic hygiene. Hand hygiene and Disinfection and cleaning with water and detergent combined are the most important routines to prevent spreading of disease. In conclusion the differences between the veterinary and the public health sector are small, but some basic differences exist due to the nature of the patient?s needs.

Introduction. Infection Prevention is one of the surgical nurses' main responsibilities. One of the steps which patients undergo in this purpose before surgery is the preoperative skin desinfektion. Background. The patient washes the day before surgery with Descutan cutaneous sponge 4 %, a sponge containing chlorhexidine.

ABSTRACTIntroduction: Preoperative hand Disinfection aims to prevent surgical site infections. After the preparing hand wash, drying is performed using an aseptic technique. It?s important to dry hands thoroughly in order to achieve the full effect of the alcohol based hand Disinfection. Due to the lack of a evidence-based guideline on this procedure, the hand drying techniques differ among operating theatre nurses, depending on which technique seen as the most appropriate.

The purpose of this work was to investigate the adherence to basic hygiene routines among staff and to investigate if there is any difference between the adherences in diverse professions. The purpose was also to study how staff rates their own adherence to current guidelines. Data for the study were collected through observations and questionnaires. Altogether 35 people were observed and 15 answered the questionnaire. Maximum adherence was found in the category of "hand Disinfection after patient contact" with a score of 96%.

This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially Disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is Disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal Disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..

This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of Disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterDisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV Disinfection of dishware.

Syftet med denna litteraturstudie var att beskriva varför följsamheten gällande handhygien ofta är låg bland vårdpersonal, samt hur man kan öka följsamheten för handhygien bland vårdpersonal. Metoden som använts var en litteraturstudie. Datainsamling skedde via databaserna Medline (PubMed), Cinahl (EBSCO host) och Academic Search Elite. Sökorden som använts: prevention, hand Disinfection, hand washing, infection control, nosocomial infection och education. Totalt användes 15 vetenskapliga artiklar.

To be able to give optimal care to patients in small animal hospitals, we have to have knowledge about how to prevent the spread of infection. An important part in this is hand hygiene routines. We have to clean hands whenever they are visibly dirty, and disinfect them regularly in between. Another important part is the cleaning and Disinfection of the environment in the clinic, and also the cleaning, Disinfection and sterilization of medical instruments. Other important parts are isolation of patients with known infections, to wear clothes with short sleeves and to wash them at least once daily, to wear gloves, having short nails and not wearing jewelry when working.

Aim: The aim of this paper was to investigate whether scientific evidence exists to improve, of students? perceived, insufficient infection control in isolation facilities in companion animal hospitals in Sweden. Material and methods: A question was emailed to the students in the last year of the animal nursing program at SLU in the spring 2012 to get their view of perceived insufficient infection control. A literature study was thereafter preformed using the search engine Web of Knowledge. Results: The students reported several perceived shortcomings which were divided into five categories: basal hygiene, isolation routines, cleaning and Disinfection, patient flow and other. Studies supporting that the shortcomings perceived by the students also exist in human health care and to some extent in animal clinics and hospitals were found. Furthermore, scientific evidence that improved hand hygiene, glove procedures and cleaning and Disinfection reduces the risk of nosocomial infections in humans was reported. Conclusion: There is not a lot of research performed in the area of infection control in animal nursing.

Bath has been a part of human history for a long time. Today bathing/swimming inmunicipal pools is for people of all ages and it is possible to take swimming courses,exercise or enjoy recreation. The municipal indoor pool of Hogdalen in Sweden wasbuild in the sixties and has had problems with high levels of heterotrophic bacteria. Thefacility has two larger pools, one adventure park for young kids, two smaller bath tubsand a jacuzzi. To improve water quality UV light and coal filter were installed inOctober 2009 to the already existing purification system.

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

Alla patienter som genomgår någon typ av operation där man penetrerar huden har en ökad risk att drabbas av en postoperativ sårinfektion. Syftet var att utforska de preoperativa åtgärderna huddesinfektion och hårborttagning relaterat till uppkomsten av postoperativa sårinfektioner. Metoden var en systematisk litteratur studie där nio artiklar användes som underlag. Resultatet visade att klorhexidin reducerar bakterierna på huden, men ingen signifikant minskning av antalet postoperativa sårinfektioner kunde påvisas. Av hårborttagningsmetoderna rakhyvel, rakapparat och hårborttagningskräm ger rakhyvel upphov till fler små sår..
