Reverse Osmosis Technology

Reverse Osmosis is a sophisticated water purification process that was first successfully demonstrated on the UCLA campus by Professor Sydney Loeb in 1960. To understand reverse osmosis it is logical to first describe osmosis. Osmosis is a vital function performed by living cells and therefore this is the context in which it is explained. Through osmosis cells are nourished by allowing passage of small molecules like oxygen, carbon dioxide, glucose and amino acids while larger molecules like starch and protein are not allowed.

An Intro to Activated Carbon

Activated carbon is a valuable weapon in the arsenal of water treatment technologies. It is widely used to remove contaminants from water. Activated carbon is an amazing substance which justifies a brief explanation. What is it? The primary raw material for activated carbon is any organic material with high carbon content such as wood, coconut shells and coal. Granulated activated carbon is produced by grinding the raw material, adding a suitable binder to give it hardness, re-compacting and crushing to the correct size. The carbon is activated by thermal decomposition in a furnace using a controlled atmosphere and heat. This process produces a product with an incredibly large surface area per unit volume. One quart of carbon provides a surface area equivalent to six football fields.

Smelly Hot Water

Smelly Hot Water It is common for cold water with a high sulfate content to transform from odor free to obnoxiously smelly after passing through the hot water heater. Typically the sulfates react with the magnesium (and even the aluminum) anode rod to chemically reduce the sulfate to sulfide. It is also speculated the smell may be the magnesium rod reacting with naturally occurring anaerobic bacteria creating hydrogen sulfide gas. To rectify the problem the magnesium rod needs to be replaced with an anode rod comprised of an aluminum/zinc alloy rod. This specialty anode rod is less reactive with the sulfate thus eliminating the reduction reaction. The cost for a typical 39 anode rod is $70.00.
