Home water purification systems have been growing in popularity for homes as well as businesses. There are dozens of different kind s systems. There are systems that are just filters attached to your faucets to run your water through some activated charcoal. These filter out whatever solids might remained in your treated water. There are systems that use electrolysis, activated charcoal, and UV light to filter solids, remove chemicals, and kill microbes. A plumber can walk you through the different types of systems. However, the basic question remains concerning who needs which systems.
Municipal Water Supply
If you are on a trustworthy municipal water supply, you likely don’t need a complex water purification system. The water coming into your home should be free of toxins, microbes, and dangerous solids. There are some cases in which the pipes leading into your home might be old enough to have lead and might be leaching lead into your water. In that case, you’ll need fixtures that filter out lead. In some cases, the water coming into your home might be safe but just taste funny. If you want something a little more permanent than the filters that attach to faucets, you could have a system installed by a plumber.
In those cases, the plumber will install a system that is basically a charcoal filter but on a larger scale. All of the water coming into your house will run through the system. It will remove solids that might make water taste or smell funny.
If you live in a rural area, you might get your water from a local well. In that case, you’ll need to have a full water filtration system. That system will basically have three functions. When water is piped from your well, it will need to have solids removed. It will need to have chemicals removed. Lastly, it will need to have microbes killed. To remove solids, the water will likely be run through a multi-step filter. The filter might begin with clean sand, then work down to activated charcoal. That will remove most solids. Then, it might undergo electrolysis which passes the water through charged particles. The charged particles will be designed to react to chemicals suspended in the water but not to water itself.
Finally, the water will be treated with UV light. The UV light will kill any virus or bacteria in the water. That will leave you with pure, filtered water.
A plumber will be able to install that type of system for you.
