Aside from Marikina, the sewage treatment plant also covers the town of San Mateo in Rizal and other nearby areas. [2] It is built on a 2 hectares (4.9 acres) land with an elevation of 26.5 meters (87 ft) above ground as measure against flooding. The facility discharges treated water to the Marikina River. [3]
The Metropolitan Waterworks and Sewerage System [1] (Tagalog: Pangasiwaan ng Tubig at Alkantarilya sa Kalakhang Maynila), [5] formerly known as the National Waterworks and Sewerage System Authority (NAWASA), is the government agency that is in charge of water privatization in Metro Manila and nearby provinces of Cavite and Rizal in the Philippines.
This was not simply modern calcium chloride, but contained chlorine gas dissolved in lime-water (dilute calcium hydroxide) to form calcium hypochlorite (chlorinated lime). The chlorination of the water supply helped stop the epidemic and as a precaution, the chlorination was continued until 1911 when a new water supply was commissioned. [7]
Chloramination is the treatment of drinking water with a chloramine disinfectant. [1] Both chlorine and small amounts of ammonia are added to the water one at a time which react together to form chloramine (also called combined chlorine), a long lasting disinfectant. Chloramine disinfection is used in both small and large water treatment plants.
San Mateo is raised from being a municipality in 1993 to a municipality under the term (1992–2001) of then Mayor Crispin "Amo" Santos: 1997–1999: San Mateo is awarded the title of "The Cleanest and Greenest Municipality" in Rizal. 2001–2006: San Mateo inaugurates a new town hall during the term of the late Mayor José F.

Chlorine can be manufactured by the electrolysis of a sodium chloride solution , which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2). These two products, as well as chlorine itself, are highly reactive.
The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, noncorrosive operation. [2] Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water releasing carbon dioxide into the steam.
