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.

playground @ west coast park (15 Oct 11)
Thought we'll bring the girls to west coast park in the morning, since we have some time.
Natalie didn't want to wake up, but jumped out of bed when she heard we are going out. We left the house early and reached west coast park at 9.00am. Turns out it's Keppel walk and fun day, so car park was full. Thus I parked further away at the more secluded car park 2 and walked back to join the girls at the playground.
Cayla didn't liked the sandy playground, so we split and I brought cayla to the toddler playground which is rubberized.

We ended the playtime with a McDonalds meal
