Introduction to water Treatment

3. bacteria and particles or coagulants and impurities that have come together to form a cluster.
7. is an expression of the intensity of the basic or acidic condition of a liquid.
8. are added to help remove light, fine particles and other materials suspended in the water.
9. factor The ratio of the true power passing through an electric circuit to the product of the voltage
11. The chemicals neutralize the electrical charges of the fine particles
13. The gradual decomposition or destruction of a material by chemical action
15. A substance that is poisonous to a living organism.
16. water Water in its natural state, before any treatment.
19. The process of settling and depositing of suspended matter carried by water
20. data sheet intended to provide comprehensive information about a substance or mixture.

1. sample a collection of individual samples obtained at regular intervals.
2. well A reservoir for the storage of filtered water of sufficient capacity
3. The gathering together of fine particles after coagulation to form larger particles.
4. residual The concentration of chlorine present in water after the chlorine demand
5. A wall or plate placed in an open channel and used to measure the flow of water.
6. organisms bacteria, viruses, protozoa, or internal parasites, capable of causing disease.
8. A group of bacteria found in the intestines of warm-blooded animals and in plants, water.
10. which organisms use the oxygen in water while stabilizing decomposable organic matter
12. sample A single sample of water collected at a particular time and place
14. The capacity of water or wastewater to neutralize acids.
15. an optical property of the water based on the amount of light reflected by suspended particles.
17. rain Precipitation that has been rendered (made) acidic by airborne pollutants.
18. Test A laboratory procedure that simulates coagulation/flocculation with differing chemical doses.
19. The settleable solids separated from liquids during processing.
