water treatment

Treatment of water is basically using a variety of processes to improve the incoming water source to a outgoing water whose quality meets a certain standards or concentration. Very often the final water quality is dictated by the local water regulations with the aim to ensure that public health is not compromised.

Processes will thus vary. Few people realized that thus incoming water quality is a critical factor in determining which process to use to treat the water to the required quality. Cost is a factor as there is a need to optimism the operation cost and effectiveness of treatment. Source control of water quality remains the most effective, though the hardest to achieve.

The main issue is that changing treatment process is costly and time consuming, especially if the source water quality changes. There is no one size fit all treatment process. The technology now is thus still very much a multi barrier treatment process.

per capital consumption

Our household average water usage is about 7cubic meters, and with 5 people in the house, we use about 50 liters per person per day. Might not be the exact way to calculate lpcd and not really an accurate way to measure individual consumption but it's a rough figure.

We don't do very special ways to save water and with children in the house, we do wash alot of clothes. Water efficient taps and drum type washing machines, but mostly a prudent way of using water like taking short showers less than 5 min, reusing our bath water to wash the floor outside the house helps alot.

It's been said that people used to using alot of water for their showers and washing can't get used or are not comfortable with low flows. Technology and design of water efficient fittings have come to a stage now whereby it can be quite comfortable to use water efficiently. It's just a matter of mindset and a willingness to adapt.

Would you be willing to change?
