Operation Water Biology Test Procedures

Operation Water Biology Test Procedures

These are the directions for performing the tests that you will refer to each time you need to determine the total chlorine, free chlorine or ammonia concentration of a water sample.It is important to follow these testing instructions very closely. Extra test strips are not provided so you will need to make each one count.

Ammonia in Water Problem-Based Learning Set

You are a water treatment plant operator for your city’s local water treatment plant. Your job is to watch the water’s chemical composition for any chemicals that could be dangerous to your city’s inhabitants. This means that you conduct multiple types of tests on the water on a regular basis in order to collect the data you need.

Operation Water Biology Lesson One Chlorination and Dechlorination The purpose of a water treatment plant is to take raw water form a well or fresh water source, remove all of the contaminants and make the water safe to drink.

Lesson Three: Ammonia and Chloramine

Lesson Three: Ammonia and Chloramine

Students will learn about the sources of ammonia in ground water, the consequences of high ammonia concentrations in water supplies, and the manner in which these problems are usually dealt with. Students will learn about biological filtering as a way to use bacteria to remove ammonia from water. Students will learn about the chemical reaction between chlorine and ammonia which results in the creation of chloramine and will learn about chloramine. Students will be able to demonstrate calculations involving concentrations, volumes and dilution factors.

Lesson Four: Ammonia and Chloramine Experiment

Lesson Four: Ammonia and Chloramine Experiment

Students will learn more about chemical reactions involved in the water treatment process by participating in an experiment examining these reactions. Students will collect and analyze experimental data on chemical reactions. Students will be able to demonstrate calculations involving concentrations, volumes and dilution factors.

Lesson Five: Consequences of Inadequate Drinking Water Treatment

Lesson Five: Consequences of Inadequate Drinking Water Treatment

Students will expand their knowledge of the problems caused by ammonia in drinking water sources. Students will investigate the quality of their local water and that of a number of samples from the surrounding area. Students will act to help any communities which are found to have improperly disinfected drinking water.
