When seeking a simple yet effective means to control contamination of water – the answer lies in a filtration system. These are a relatively simple and effective way to control a variety of contaminants. Filter systems are of various types. Some of these are mechanical filters, activated carbon filters, oxidizing filters and neutralizing filters. The moot point to be borne in mind with respect to filtration systems is that they are designed for use only on potable water. This means is that the water supply where they are used should be clean, uncontaminated and suitable for drinking.
