Maynilad water treatment process

Mixing causes lightweight particles in the chemically treated to clump together, or coagulate, into much larger particles.

Maynilad water treatment process

Its application has been extended to the removal of pathogenic microorganisms, dissolved solids, anions and trace-heavy metals. The plant has been fabricated with 14 units of microfiltration and six units of reverse osmosis assemblies. One strategy frequently employed to remove these solids is gravity filtration.

Other methods are also employed to remove the organisms, including through coagulation, sedimentation, and filtration. The plant supplies potable water to 4, households. Coagulation Aluminum sulfate is added to the water entering the plant. Residents and establishments in Muntinlupa City and neighbouring areas currently draw water from deep wells. We derive our Mandate primarily from Republic Act which states the basic goals of the System and declares as its major policy the proper operation and maintenance of waterworks system to ensure an uninterrupted and adequate supply and distribution of potable water for domestic and other purposes and the proper operation and maintenance of sewerage systems in its service area which includes the whole of Metro Manila and parts of Cavite and Rizal. Disinfection In many water supplies, the most serious health threats are posed not by chemicals, but by infectious organisms, such as bacteria, in the water. Schematic Flow Process of a Water Treatment Plant The processes of screening, flocculation, sedimentation, filtration, and disinfection work together to remove the unwanted substances from our water supply, making it safe to drink and appropriate for other uses. The intensity of the mixing is then reduced, allowing well-defined pinhead-sized particles of floc to begin to form. It is the largest lake in the Philippines and the third-largest freshwater lake in South East Asia. The new treatment plant uses water from Laguna Lake as an alternative source to the Angat Dam.

Residents and establishments in Muntinlupa City and neighbouring areas currently draw water from deep wells. Water purification To ensure that water drawn from Laguna Lake is fit for drinking, an advanced process of microfiltration and reverse osmosis has been adopted to purify the water.

When water is allowed to sit, heavy suspended particles, such as sand, will settle to the bottom over time, as they are denser than water. Government concession Maynilad is the water and wastewater services provider for the 17 cities and municipalities that comprise the West Zone of the greater Metro Manila area.

The intensity of the mixing is then reduced, allowing well-defined pinhead-sized particles of floc to begin to form. The water that remains at the bottom of the filter no longer contains those solid impurities. We derive our Mandate primarily from Republic Act which states the basic goals of the System and declares as its major policy the proper operation and maintenance of waterworks system to ensure an uninterrupted and adequate supply and distribution of potable water for domestic and other purposes and the proper operation and maintenance of sewerage systems in its service area which includes the whole of Metro Manila and parts of Cavite and Rizal. Other Al and Fe salts, including polyaluminum chloride, ferric chloride, and ferric sulfate, may be used as well. Therefore, these particles must be removed from the water by another process known as sedimentation. The facility is expected to produce million litres of water per day MLD. These screens, however, must be cleaned periodically to remove any objects that have become stuck and prevent the screen from becoming clogged and impeding water flow into the facility. This is done through the addition of chorine, and is repeated after all other treatment sequences to ensure the destruction such organisms. Filtration Oftentimes, however, the particles generated by the previous precipitation reactions are too small to settle efficiently by sedimentation. The most common coagulant used in water treatment facilities is aluminum sulfate alum, Al2 SO4 3.

The intensity of the mixing is then reduced, allowing well-defined pinhead-sized particles of floc to begin to form. These objects can clog the water-treatment system and therefore must removed before the water enters the treatment plant.

The plant is located in the city of Muntinlupa, situated 22km south of Metro Manila in the Philippines. The water that remains at the bottom of the filter no longer contains those solid impurities. Therefore, these particles must be removed from the water by another process known as sedimentation.

When water is allowed to sit, heavy suspended particles, such as sand, will settle to the bottom over time, as they are denser than water. Connectwise: Your recommended content. The water, now free of the suspended impurities, can be collected from the top without disturbing the layer of sediment at the bottom, which is eventually discarded. These screens, however, must be cleaned periodically to remove any objects that have become stuck and prevent the screen from becoming clogged and impeding water flow into the facility. The solids formed from precipitation get stuck in the pores, and are thus removed from the water as it passes through the porous medium. In this process, water containing solid impurities is passed through a porous medium, typically layers of sand and gravel pieces. Coagulation is the process of gathering particles into a cluster or clot, often achieved by the addition of special chemicals known as coagulants.
