Producing a better quality software system requires an understanding of the indicators of the software quality through defect detection, and automated testing. This paper aims to elevate the design and automated testing process in an engine water pump of a drinking water plant. This paper proposes how software developers can improve the maintainability and reliability of automated testing system and report the abnormal state when an error occurs on the machine. The method in this paper uses literature to explain best practices and case studies of a drinking water plant. Furthermore, this paper is expected to be able to provide insights into the efforts to better handle errors and perform automated testing and monitoring on a machine.

Fourteen waterborne epidemics occurred in Finland during 1998-1999. About 7,300 illness cases were registered in these outbreaks. All except one of the waterborne epidemics were associated with undisinfected groundwaters. An equal number of waterborne epidemics occurred in public and private water systems, but most cases of illness occurred in public water systems. The three largest epidemics comprised 6,700 illness cases. Insufficient purification treatment unable to remove Norwalk-like viruses caused the only waterborne epidemic in a surface water plant. The main reasons for groundwater outbreaks were floods and surface runoffs which contaminated water. Norwalk-like viruses caused eight and Campylobacter three of the outbreaks. In two cases the epidemic ceased by the exhaustion of susceptible persons in the exposed community but in most cases it was terminated by changing the water source, boiling the drinking water, and starting chlorination.

Drinking Water Purification

According to contaminated raw water and drinking water purification processes, volatile/semi-volatile organic compounds in water are determined by GC-MS. The changes of the organic along the process and water quality from unsafe to safe process were revealed. The results show that there are odorous substances such as heptanal in raw water, which are not detected after the filtration. The composition of volatile organic compounds changes a lot after the ozone activated carbon process, thus anthropogenic pollutants are no longer detected such as 5-ethyl-5-(3-hydroxy isopentyl)-barbituric acid. However, biological metabolites that are not present in raw water such as cedrenol appear. Except disinfection by-products after disinfection, there are a variety of halogenated compounds as 1-1-dichlorocyclobutane and 1-chloro-3, 3-dimethyl-butane. Some hydrocarbons and alcohols in the finished water have little impact on drinking water safety.

Abstract Aquatic macro-organisms, such as naidids, propagate excessively in biological activated carbon (BAC) filters. This has become a troublesome problem for drinking water plants. For successful control of naidid contamination risk, it is necessary to determine the population dynamics under different environmental conditions within drinking water plants, with special emphasis on BAC filters. In this study, field studies of naidid distribution in a drinking water plant were conducted, and the effects of temperature and dissolved oxygen (DO) on naidid population dynamics were investigated using the life table method. The results indicated that naidid pollution in the water plant occurred seasonally and was induced by the excessive propagation of naidids in the BAC filters. Increased temperature and DO increased the naidid intrinsic rate of natural increase and decreased the naidid population doubling time. The life table method was also used to acquire the reproductive parameters of naidids in BAC filters based on simulative experiments. These results indicated that naidids can reproduce asexually in BAC filters, and the population doubling time was 12.60 days.
