| HOW REVERSE OSMOSIS WORKS |
| WHAT IS THE MAINTENANCE SCHEDULE FOR THE BIONIC RO SYSTEMS ? |
| The three pre-filter cartridges should be changed every 6 months. The first is a 5 micron sediment cartridge. The second is a Carbon Cartridge. The third is a 1 micron sediment filters. (some system comes with the Extruded carbon filter.) Failure to change the cartridge every 6 months may allow chlorine to destroy the membrane. It is very easy to change the prefilters. Just order the needed filters from us and all system come with the housing wrench to open the filter housings so you can maintain your system yourself and feel confident about your drinking water. |
| WHEN SHOULD THE MEMBRANE BE CHANGED ? |
One indication is a gradual reduction in water production caused by a layering of minerals and salts on the membrane surface. Another is a gradual deterioration in the quality of water being produced. You my notice a different taste or more white scum on the inside of a pan of water you are boiling. This might mean the R.O. membrane is disintegrating and requires replacement.
OSMOTIC PRESSURE: When a solution, such as salt water, is separated from pure water by a membrane which is impermeable to the salt, a flow of water will occur from the pure water to the salt solution. The driving force for this flow is called the osmotic pressure and its magnitude depends on the number of salt particles in the solution.
Note that the osmotic pressure depends on the number of particles and not on the total mass of particles. For example, 1 g/L of a small solute, such as sodium chloride, will exert a greater osmotic pressure than 1 g/L of a large solute, such as protein. For water to flow from the salt solution to the pure water this solution must be exposed to a hydrostatic pressure greater than its osmotic pressure. This is the principle of reverse osmosis.
BACTERIA: Bacteria are single cell microorganisms capable of replicating on their own. They can be divided into two broad categories: aerobic (requiring oxygen) and anaerobic (not requiring oxygen). Bacteria can live in a very broad range of habitats. Some, for example pseudomonads, can thrive in environments containing very low level of nutrients. These bacteria are frequently slime producers and are a major problem in water treatment systems. Other bacteria, which adhere to surfaces, secret gelatinous material which serves to protect the bacteria from chemical disinfectants. This combination of bacteria and their protective coating is sometimes referred to as biofilm. The concentration of bacteria in water is commonly given in terms of colony forming units (cfu) per ml. A colony forming unit is a viable bacterium able to replicate to form a whole colony when incubated in a given environment

| AT FACTORS AFFECT THE QUANTITY AND THE QUALITY OF THE WATER PRODUCED ? |
There are four major variables to consider:
- PRESSURE. The greater the water pressure, the better the quantity and quality of the water produced. Water pressure of 60 psi ideal. PurePro include one booster pump can make sure the water pressure.
- TEMPERATURE. 76*F is the ideal water temperature for R.O. 40*F water will cause the production of R.O. water to fall to half of that at 76*F. The maximum water temperature recommended is 85*F.
- TOTAL DISSOLVED SOLIDS (TDS). The higher the amount of dissolved contaminants in the water, the lower the quantity of water produced. A high level of TOTAL DISSOLVED SOLIDS can be overcome with additional water pressure.
- MEMBRANE. Different membranes have different characteristics. Some produce more water than others; some have better contaminant rejection capabilities; some have greater resistance to chemical abrasion for longer life. PurePro system include RE1812-70 The Thin Film Composite(TFC) membranes combine the best of these characteristics and are considered the finest membrane in the world.
