    Which of the following are not the process of water treatment?

    • Blending

    • Coagulation

    • Disinfection

    • Sedimentation

    Correct Answer
    A. Blending
    Explanation
    Blending is not a process of water treatment because it refers to the mixing of different water sources or types, rather than the actual treatment methods used to remove contaminants and impurities from water. The other options listed - coagulation, disinfection, and sedimentation - are all common processes used in water treatment to remove particles, kill microorganisms, and separate solids from the water.

    There are two (2) types of contaminants that are present in an untreated water, which is aesthetic and health-related contaminants.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because untreated water can contain both aesthetic and health-related contaminants. Aesthetic contaminants refer to substances that affect the taste, odor, or appearance of water, such as minerals, algae, or organic matter. Health-related contaminants, on the other hand, can include bacteria, viruses, parasites, chemicals, or heavy metals that can pose a risk to human health if consumed. Therefore, it is important to treat water to remove these contaminants and ensure its safety for drinking and other uses.

    Correct Answer
    A. Trap aerators
    Explanation
    Trap aerators are not a type of aerator. Aerator is a device that introduces air into a liquid, typically water, to increase oxygen levels. Cone aerators, cascade aerators, and spray aerators are all types of aerators commonly used in various applications. However, trap aerators do not exist as a recognized type of aerator.

    Screening is the process of removing debris such as woods, leaves, aquatic plants, rubbish and others. In this process, it consists of two (2) types of filter, which is;

    • Rock filter

    • Fine filter

    • Sand filter

    Correct Answer
    A. Fine filter
    Explanation
    The given correct answer is "Fine filter". In the screening process, there are two types of filters used: rock filter and fine filter. The rock filter is likely used to remove larger debris such as woods and rubbish, while the fine filter is used to remove smaller particles like leaves and aquatic plants. The sand filter is not mentioned in the options, so it is not the correct answer.
