Water Filters

A filter is a device which removes impurities from water by means of a fine physical barrier and/or chemical processes. Filters are used to cleanse water for irrigation, drinking water, aquariums, and swimming pools. Water Filters can be bought at stores to filter drinking water. Two major brands are PUR and Brita. These water filters remove things that are harmful to your health, things that can increase the chance of getting cancer, and things that taste or smell bad. The phyiscs of filters is based on sieving, ion exchanges and other processes.

Drinking Water Purification

In July 2002, Singapore announced that a process named NEWater would be a significant part of its future water plans. It involves using reverse osmosis to treat domestic wastewater before discharging the NEWater back into the reservoirs.

In the United States, household drinking water filtration systems, including a reverse osmosis step, are commonly used for improving water for drinking and cooking. Such systems typically include four or five stages:

- a sediment filter to trap particles including rust and calcium carbonate
- optionally a second sediment filter with smaller pores
- a carbon filter to trap organic chemicals and chlorination
- a reverse osmosis filter with a thin film composite membrane (TFM or TFC)
- optionally a second carbon filter

Water Ionizer/Ioniser

A Water Ionizer is an appliance that ionizes water through a method of electrolysis. Major water ionizer manufacturing companies (e.g Jupiter Dong Yang Science) claim that consumption of alkaline water with a lower ORP and higher oxygen content may improve health. There are many nutrition experts that support this theory as well.

The water ionizing system was first introduced in Japan some 30 years ago.

Common claims about the health benefits of ionized water include the claim that ionized water is more readily absorbed by the body than ordinary water, and that minerals in ionized water are more readily available to the body. A link is often made between consumption of nonionized water and a medical condition known as chronic cellular dehydration. Another claim is that ionized water is an antioxidant. Although western medicine has not yet confirmed the benefits of drinking alkaline water, there seems to be an ample amount of testimonials from consumers who have reversed disease through the use of a water ionizer.
