MEMBRANE FILTRATION FOR WATER AND WASTEWATER Membrane filtration, widely used in chemical and biotechnology processes, is already established as a valuable means of filtering and cleaning wastewater and industrial process water. More recently, tubular and spiral membrane plants have begun to be used to filter impurities from drinking water in regions where conventional treatment proves…
HOW RO WATER PURIFIERS WORK The RO water purifier at your home or office might appear to be a complex system to you but in reality it involves a very simple water purifying process. Here are a few points that I would like to share before explaining the entire Reverse Osmosis (RO) process. All RO water purifiers…
CONVERTING SEAWATER TO FRESHWATER ON A SHIP: FRESH WATER GENERATOR EXPLAINED Fresh water generator, one of the important machinery on board a ship, is something that cannot be done without. Fresh water produced from fresh water generator is used for drinking, cooking, washing and even running other important machinery which use fresh water as a…
HOW DOES REVERSE OSMOSIS WORKA SIMPLE AND STRAIGHTFORWARD WATER FILTRATION PROCESS Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semipermeable membrane. A few impurities found in tap water that can…
WHAT IS ELECTRODEIONIZATION? Electrodeionization is a water treatment technology that has gained popular acceptance because the process does not use chemical treatments. In such a system, there are no moving parts. Water is passed between a positive electrode and a negative electrode. Semipermeable ion-exchange membranes separate the positive and negative ions, creating deionized water. The commercial technology was…
