Understanding the Steps in a Water Purification Diagram
The complex process shown by a water purification diagram starts with the removal of various metal ions through a process known as ion exchange. Also called water softening, ion exchange uses large tanks which are filled with a special tube that carries a slightly negative charge. Ion exchange gives efficient removal of the metals responsible for hard water pipe deposits. In addition, the process eliminates various heavy metals, such as lead, iron, mercury and cadmium, many of which have been co-related with a number of well-publicized health topics.
Next on the water purification diagram is granular activated carbon. Once the water moves through the ion exchange system, it passes into an oversized granular activated carbon bed. Carbon filtration, which uses a process known as adsorption, is a particularly efficient technique for chlorine elimination.
Granular activated carbon filtration is the most used technology in home filter systems. Unfortunately, these home systems are often poorly checked.
The next step in the water purification diagram is a simple paper sediment filter. The sediment filter acts as a sieve for large particles which may be present in the water. It is needed to remove these large particles first in the process to prevent clogging of the more sensitive parts utilized at later stages.
Reverse Osmosis is next on the water purification diagram. Reverse osmosis is at the centre of water purification processes. Osmosis is a normally occurring process whereby water goes across a membrane due to a pressure difference between one side of the membrane and the other side. As osmosis occurs, the concentration of dissolved material on each side of the membrane is equal to an equilibrium state. The more concentrated one side of the solution becomes, the more diluted the other, and so on.
The five micron carbon block filter, another step in water purification diagram, is created to trap extremely small particles present in the water. The five micron size designation signifies that bigger particles will be trapped by the filter. The filter itself is an extruded block of carbon, giving an additional measure of adsorption capacity for the elimination of chlorine and organic contaminants. The extruded carbon block filter is made to very tight tolerances, thereby giving maximum characters for eliminating contaminants.
Succeeding the water purification diagram is ultra violet disinfection. At this step of the process, the water moves through a special chamber which has a large ultra violet light source. The microorganisms quickly die, and are trapped and eliminated during the reverse osmosis purification process.
One micron sediment filter will be the next in water purification diagram. The one micron sediment filter is a blocking device created to maintain the systems integrity during operation so that the end product holding tank is not at stake.
The second phase of chemical-free disinfection is known as ozonation in the water purification diagram. Ozonation depends on oxygen to be sure that purified water remains entirely free of contaminants.
And the last stage in the water purification diagram is storage and recirculation. After the water has moved through the preceding eight steps, it goes into the storage and recirculation stage. This storage and recirculation system has been created so that the processed and purified water will retain high purity and will be protected.
