Sewage treatment plan Sewage treatment is the process of removing contaminants from waste water and household sewage‚ both run off (effluents)‚ domestic‚ commercial and institutional. It includes physical‚ chemical‚ and biological processes to remove physical‚ chemical and biological contaminants. Its objective is to produce an environmentally safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm fertilizer). Origins

All surface water and some groundwaters require treatment prior to consumption to ensure that they do not represent a health risk to the user. Health risks to consumers from poor quality water can be due to microbiological‚ chemical‚ physical or radioactive contamination. However‚ microbiological contamination is generally the most important to human health as this leads to infectious diseases which affect all populations groups‚ many of which may cause epidemics and can be fatal. Chemical contamination

conducted was to analyse the work of a heat exchanger‚ by studying the effects of heat transfer from a hot stream and a cold stream in the heat exchanger. In the experiment we were introduced to the shell and tube heat exchanger and were told of all its parts and how to use them. The experiment started by evaluating what the heat transfer rate for a hot stream and a cold stream was within the heat exchanger. Using this information the experiment went on to analyse the heat exchanger in more detail. The log

How can the specific heat capacity of water be used to regulate temperature? Specific heat capacity is the amount of energy needed to increase the temperature of an object by 1˚C. The formula that uses specific heat is Q = mc∆T‚ where Q is heat energy‚ c is specific heat‚ and ∆T is the change in temperature. The amount of heat energy depends on the mass‚ or the size of an object‚ and the specific heat capacity‚ which depends on the substance it is made from. The specific heat capacity of water is

Stance on Ashley treatment Ashley’s treatment’s main purpose is to improve patient’s quality life‚ in other words‚ it makes it easier for the caregivers to take care of the patient. The methods under this treatment include breast bud removal‚ removing uterus to avoid menstruation cramps and limiting final height using estrogen therapy. (Ashley’s Blog‚ 2009) In my opinion‚ Ashley treatment is beneficial for both the patient and the caregivers because it minimizes pain for the patient and also makes

2006 Q4 a) The greatest decline took place between 1965 and 1970. 700‚000 metric tons - 200‚000 metric tons = 500‚000 metric tons 500‚000 metric tons/5 years = 100‚000 metric tons per year the gorundfish harvest depleted by aproximately 100 thousand metric tons per year between 1965 and 1970. b) Bottom trawling is the act of scraping the bottom of a fishing area with a large net in order to catch fish. The net‚ however‚ catches more than the intended product. The nets destroy the bottom vegetation

Title: Heat Treatment of Ferrous Objective: To determine the effect of heat treatment on mechanical properties of 1050 Steel. To reveal the microstructures of 1050 steel during heat treatments. Abstract In this experiment‚ we observed how the properties of plain carbon steel vary with the heat treatment condition. We prepared six different samples in three different heat treatment configurations and performed hardness tests on them by using the Rockwell tester and observed the microscopic
