Study Notes
Water Purification Process
- Passing water through a filter bed with grains of sand and activated carbon removes impurities, sediments, and harmful substances, improving water quality.
- Activated carbon absorbs organic compounds and chlorine, enhancing taste and odor while filtering contaminants.
Coagulation in Water Treatment
- Aluminum sulfate is added to water in the filter plant to form gelatinous aluminum hydroxide, which helps in coagulating and removing suspended particles.
Water Source for Balara Filter Plant
- Water supplied to the Balara Filter Plant primarily comes from the La Mesa Watershed, transported through large pipeline systems.
Sedimentation Ponds Function
- In sedimentation ponds, aggregates settle at the bottom, allowing cleaner water to rise to the surface for further treatment processes.
Role of Chlorine in Water Purification
- Chlorine gas is introduced as a disinfectant during purification, effectively killing bacteria, viruses, and other pathogens, ensuring safe drinking water.
Copyright on Government Works in the Philippines
- Prior approval for exploiting works created by the Government of the Philippines must be obtained from the National Commission for Culture and the Arts (NCCA).
- According to Republic Act 8293, section 176, there is no copyright on works created by the Government of the Philippines.
Ownership of Borrowed Materials
- The publisher and authors of the module claim ownership over the borrowed materials included, indicating proper acknowledgment of sources.
- Government agencies or offices can impose the payment of royalties for exploitation of their works only under specific conditions outlined in relevant legislation.
