Adamson Goes Green with Its New STP

Date Posted: Nov 2, 2009 at 01:17:27 AM

As part of its commitment to become not only socially responsible but environmentally responsible as well, Adamson University unveiled its new Sewage Treatment Plant (STP) last November 5, 2009 in simple rites presided by University President Fr. Gregg Bañaga Jr., C.M.


The STP is Adamson’s latest step in waste management and water conservation. The facility is composed of a control room housing the programmable logic control and water chambers where several processes take place. Wastewater from the ST and OZ buildings are directed to the plant where it first goes through neutralization. Water will then flow to the to sequential batch reactor or the “digester,” where microorganisms do their work. After that it’s off to chlorinization for disinfection and then to filtration before it goes back to the buildings’ toilets for flushing. The sludge from waste matter will be collected and treated separately to convert them as fertilizer.


According to Engr. Merlinda Palencia, Chemical Engineering department chair and one of the main administrators in charge of the plant, the STP can accommodate wastewater from all buildings in the campus plus that of two more new buildings. The plant processes a maximum water level of 250 cubic meters.


The inauguration and blessing of the plant, which is located at the back of the OZ Building, was attended by the University’s top management and guests from the various departments and colleges of the University. The College of Engineering is at the forefront of the project led by the Chemical Engineering department. Alpine Systems Corporations, represented by its engineers who were also AdU alumni, were contracted for the construction and technology of the STP.


Adamson is one of the few schools in the metro with an existing sewage treatment plant in place. This facility is expected to decrease the University’s water costs and dependence on running water for its toilets, particularly when pipes from Adamson’s other buildings are redirected towards the STP. The treated water can also be used for watering plants around the campus. In using the STP, the University can also avoid dumping its wastes into the estero that runs in between the campus.


The STP is also planned as a learning laboratory for Engineering students. It was built above-ground particularly to allow on-site instruction as well as hands-on training. The facility can also be used for other scientific research.


“The STP is our own concrete contribution to the preservation of environmental integrity,” Fr. Gregg says of Adamson’s new facility. This new gem of the campus is another pioneering effort of the University to help answer the challenges of climate change and teach environmental responsibility to every member of the Adamson community.
