Advantages of Solar Disinfection of Water SODISSODIS is a method used for

Advantages of Solar Disinfection of Water (SODIS)SODIS is a method used for water purification in developing countries especially by people who don’t have access to clean water (Suter, 2016). All it require is sunlight and PET bottles. Many scientific studies confirmed the effectiveness of the SODIS method, having said that a task was carried out to get information about SODIS specifically the advantages of SODIS (Suter, 2016).The needed information was identified by searching for the topic of the task then defined it using simple words then showed current knowledge of the topic. I acknowledged that there is a need to achieve required information. I also went in the field to search for information myself.The topic required secondary information because it was collected by somebody else who researched about it. I never participated in the events or conditions when the research was going on that is why it is secondary information.I visited the clinic that is situated on main campus (University Of Namibia Windhoek) to ask the head nurse questions about SODIS. I then went to the central hospital to ask one of the head department advantages of SODIS. After that I went to the World Health Organization (WHO) and UNICEF and enquire benefits of SODIS also visited Red Cross webpage. WHO and UNICEF gave me pamphlets that contain SODIS information. I sorted the information that I collected in ascending order from least valid information to the most valid information.The information was accessed by visiting the clinic, central hospital, WHO, UNICEF and Red Cross. I read through everything they have provided me with. WHO and UNICEF gave me broad information therefore I had to separate the information I wanted from unwanted information. I also read through the pamphlet and noted the information which I thought was valid. Red Cross webpage provided an article which I read and again noted down the wanted information.It might be difficult to find information which one is looking for within a source therefore there are easier procedures that don’t consume time. I searched for information within a source such as a pamphlet by using different types of organization tools such as the topic and pictures. Pictures are usually on the first page of the pamphlet and they always give hint on what the pamphlet is all about, that enabled me to read the whole leaflet. The organization website was also provided in the leaflet and gives more details since the information in the leaflet is summarized.Information-Retrieval System (IR) involves searching for information from large sources which are specifically formatted as formal data. Having said that, all the information collected from the organization (WHO, UNICEF and Red Cross), clinic and hospital were formalized therefore I read everything and separated the relevant information from irrelevant information.I used the information I collected to get the advantages of SODIS and how they benefit the disadvantaged people. The method require empty bottles therefore once the user has acquired the bottle(s), there is no need to buy again because they can be reused (Suter, 2016). This method does not have residual chemical therefore recontamination is unlikely because water is served directly from a small, narrow necked bottle. The bottle can be placed on any surface as along as its receiving direct sunlight People will accept and some have accepted to use it because it’s a simple method and it does not have complicated procedures. SODIS method is proven that it reduces bacteria, viruses and protozoa in water also reduce diarrhea. I extracted the relevant information using the six steps. Pre-processing prepares the data from primary processing or for further analysis by extracting data from larger set or filtering it. Finding and classifying concepts deals with locations, events and other pre-specified types of concepts that are detected and classified. Connecting the concepts, this is where the identification of relationships between the extracted concepts take place. Unifying, this is when extracted data is presented into standard form. Getting rid of noise involve eliminating the duplicated information. Enriching your knowledge base deals with saving extracted data information in the database for further use.The retrieved information came from different sources therefore to prevent confusion, the information was organized in climatic order. Whereby the data is organized in order of increasing importance until the last piece which is more important.Sometimes information from sources can be misleading. We cannot always tell that information is relevant by looking at the first stage. For that reason I took my time to carefully scan or go through every information that way I will be able to decide if the information is relevant or not. At this point I considered all the questions which I prepared and asked myself what I am hoping to accomplish by the end of the task and the kind of information I hoped to achieve.Normally people use charts and graphs to visualize what is going on or what the information is saying. In this case I used the standard format whereby I organized in order of importance because it helps build the strength of idea. Each new piece of information presented builds on the last piece of result. Organizing by importance also works when presenting in order of increasing (Burke, 2019). Judging and evaluating of piece of work helps reflect on what you are trying to achieve, assessing how far the task has come and successful also identify the possible changes. Evaluation has four steps that need to be followed as they give guidance on judging the work. Planning is when you decide on areas or activities that need to be evaluated (Monitoring progress and evaluating results, 2005). The information I got from the clinic situated in UNAM is less, the nurse had little knowledge of SODIS and also she didn’t understand the questions properly. The head of one of the departments gave me broad information and also his information was more based on medicine. WHO, Red Cross and UNICEF provided me with a lot of information about SODIS and they understood the questions very well. WHO and UNICEF also gave out the pamphlet that contained SODIS information. Monitoring involves collecting and recording information (Monitoring progress and evaluating results, 2005). I collected information from both health facilities and health organizations and recorded in order of importance, whereby the least important information are recorded first then follows the most important information. Interpreting is when data is analyzed and evaluated, WHO, UNICEF and Red Cross’s information were the most efficient and well detailed. The fourth one is making improvements whereby identifying and prioritizing improvement.The health organization (WHO, UNICEF and Red Cross) information is updated, they refresh their data every year. The task was completed and successful because I managed to collect all the information my task required. Although it was a success, I faced a few challenges such as barrier in communication when the nurse didn’t understand the questions properly so I had to explain the questions in details. The head of department’s information were too much into medicine. I didn’t get the information from WHO the same day I got to their office because I didn’t make an appointment so I was sent back. Because of those challenges, I will reference them not to make the same mistakes in the future. I will prepare my questions in more detailed format to prevent confusion and misunderstandings. I will also make an appointment before going to any office to prevent any inconvenience.CONCLUSIONSODIS is a very convenient and effective method that doesn’t not require energy or any form of labor because the user only have to place the bottle on the surface where it gets direct sunlight. The bottles can be reused therefore the user doesn’t not have to strain about getting a new bottle(s). The task was a success as I got the advantages of SODIS and their extra information increased my understanding and knowledge of SODIS although I didn’t include it because they are not part of the task. REFERENCEBurke, A.
