Features of a water refilling station
To begin, the Structurally, water refilling station can be operated with a minimum area of at least 20-25 square meters.
It comprises the following sections: refilling and selling room, enclosed water purification room, container washing and sanitizing room, storage room for empty and refilled containers, source water storage facility, toilet and an office. To operate the water store,
it needs five employees.
1 – Manager – Overseas store operations at least 4 hours a day
Accountant/Bookkeeper – Makes financial statement of business operations
Administrative assistant – Logs and handles cash sales and purchases
Front Liner – Accepts and refills containers of customers
Technical Asst. – Maintains and runs the machine
Driver/Delivery Man – Transport refilled containers to customer’s home
The main processes in a water refilling
station is read by raw water quality
The typical steps are filtration (several stages), softening, and disinfection.
Machines that could be installed for such
processes are the following:
Firstly, Multi-media sediment filter – removes sediments such as rust, sand and particles that are invisible to the naked eye; employs a total of 5 filters.
Secondly, Ion exchanger – replaces hard minerals with soft minerals.
Activated carbon filter – removes all organic chemicals, herbicide, pesticide, offensive odor and bad taste.
Thirdly, Reverse osmosis membrane – the heart of the system and the most expensive unit; removes inorganic minerals, bacteria and viruses while retaining its oxygen content.
Since the filter size is very small at less than 0.05 micrometre, the product water could have a total dissolved solids (TDS) of less than 10 ppm. The filtration process rejects about 50 percent of raw water volume.
Fourthly, Post-carbon filter – improves the taste of water.
fifthly, Ultraviolet lamp – ensures that the water is free from disease-causing micro-organisms.
Lastly, Ozone generator – inhibits the growth of bacteria in the product tank and prolongs the shelf life of water.employs a total of 5 filters.
The efficiency of water purification system in removing impurities is high. The 10 water quality parameters measured by Magtibay (2001) showed an average of 80 percent efficiency.
