We have been arguing against the practice of water chlorination for some time. Though water disinfection is an important tool to promote public health, we do not believe that this is the proper method to do so.
In orbital space settlements water recycling is essential. So it is quite worrisome when we read the following article on ScienceDaily:
To cite from this article (my emphasis):
If people are educated on recycled water, they may come to agree it’s perfectly safe and tastes as good — or better — than their drinking water. They may even agree it’s an answer to the critical water imbalance in California. But that doesn’t mean they’re going to use recycled water — and it sure doesn’t mean they’ll drink it.
The problem is that educated people are disgusted to use a perfectly safe product that is necessary for staying alive. Perhaps people should not think too much about the origin of their tap water – if education is apparently not sufficient in this case.
In the previous post I did not discuss particular technologies to purify waste water and to turn it into clean water. One way to remove minerals from waste water are algae.
As orbital space settlements will get most of the energy from solar power, there is little use for biofuel. However, algae have a lot of other useful applications. Continue reading Sewage and Algae
Sewers are the summit of human civilization and taxation is the price of civilization. So we are supposed to pay sewer tax, right? No, not really. In this post I will explain how space settlements could fund a sewage and waste water treatment system without having to collect sewer charges. Continue reading Sewers and Taxes
The production of safe drinking water takes several steps to remove all kind of unwanted substance out of water. One important step is disinfection, i.e. killing (possible) pathogens in water. Continue reading Water disinfection
