UMA carries out RO water production which is consumed by staff and students. The war supply comes from the ground and rainwater. The quality of drinking water is examined by PDAM (Indonesian Regional Water Utility Company) Tirtanadi and UMA has also carried out the test of the ready-to-drink water quality through the Integrated Service Unit of the Health Laboratory of North Sumatra Provincial Health Department.
The process the treated water starts from the rainwater harvesting by using water tank/ rain barrels. Then the harvested rainwater goes to the filtration stage as follows:
• Stage 1: Inline 5 Micron Sediment Filter
With only five micron rating, It is effective in removing dirt, rust and sand particles.
• Stage 2: Inline Granular Activated Carbon Filter
It takes out 99% of the chlorine and organic chemicals. It provides enhanced reduction of taste, odor, and color.
• Stage 3 Inline Granular Activated Carbon Filter
It provides effective filtration to protect your membrane. It provides for improved membrane performance up to 95% of TDS rejection.
• Stage 4 Reverse Osmosis Membrane
A thin film composite (TFC) high quality membrane that processes 80 gallons per day. It remove the following hard water contaminants that may be present in your water: lead, cooper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, nitrate, and selenium.
• Stage 5 Inline Post Carbon filter:
This carbon post filter removes objectionable tastes and odors to enhance the quality of your drinking water. We are using NSF approved post carbon to guarantee the taste of water.
The fulfillment of drinking water needs for the UMA academic community comes from 2 sources, namely treated water (RO Water) and gallon water. The average gallon water requirement for academic and administrative staff is 9500 L/month with a total daily estimate of 395 L. Meanwhile, the processing results for ready-to-drink water (RO Water) at three sites in UMA are estimated to be able to meet 60% of the needs of the academic community (3588 people) where the estimated need for drinking water per person is 0.5L, so 1794 L per day is needed. For he remaining 40% of drinking water needs, the UMA academic community is encouraged to bring their own tumblers, which are in accordance with the rector’s appeal that has been socialized. In the future, UMA plans to add 2 RO drinking water places, namely in the dormitory and in the laboratory.
Currently, UMA has also signed the Memorandum of Understanding with PDAM Tirta Sari which is expected to corroborate proper RO water processing in UMA besides other academic and student programs.
