Can you build effective homemade water filtration systems? Well, that all depends on your purpose.
If you want to keep your fish tank clean there are some acceptable homemade water filtration systems, but of course you have to buy the parts, which could cost as much as buying a ready-built unit. You would still need a standard aquarium power head and a submersible water pump.
You would also have to find a place that sells activated carbon in a bag. That might be kind of hard to find. Personally, I think the fish would be safer if you just bought a professional system.
Some people have constructed homemade water filtration systems for their outdoor ponds. You would need a plastic trash can with a lid, similar in height to the depth of your pond. You would again need to purchase some type of filtering material depending on the quality of your source water.
Once again, a waterproof pump would be required and piping. If not installed correctly, you risk electrocution. Ponds require aerating, as well as filtering in order to prevent stagnations. So, professional products may be a better choice than homemade water filtration systems for your pond.
Homemade water filtration systems are definitely not the right choice for safe drinking water. The technology is simply too complex.
There is a simple little science project that you can do with your kids, maybe on a rainy summer day, but I would not let them drink the result. There are diagrams for these projects all over the internet, so I'll leave out the details. But, it might give them an idea of how your kitchen counter filter works and you can give them this explanation.
Unlike homemade water filtration systems, our kitchen purifier has a lot of different steps inside. You know the cartridges that I replace every so often? Well, they remove things that we cannot see. We saw the dirt in that water, but not the chemicals and other things that can hurt us.
There could be bug spray, weed killer and tiny little germs that could make you sick. Homemade water filtration systems can't get rid of those things, so
I bought this nice one and now I know that you guys are safe.
For the adults, the number of steps in a system depends on which product that you buy. Most systems include an activated carbon step that removes most of the chlorine, which is put in at the treatment facilities to disinfect and prevent algae growth in the pipes.
In the better systems, there are multi-media blocks that remove VOCs, pesticides, herbicides and industrial pollutants through a process called adsorption. The best systems will also include a micron particle filter that removes microscopic sediments, cryptosporidium and giardia cysts.
They also include and ion exchange phase that removes lead ions and replaces them with potassium, so your water is safe and has a pleasant healthy taste.
That completes today's lesson on homemade water filtration systems. Hope you learned something.
