Industrial Water Filtration Systems
A variety of filters are used as both pre filtration and post process filtration. Cartridge filters are an economic solution in capital cost, but they can become high consumable cost if the wrong filters are selected. The positioning of any such filters and the clients ability to monitor the performance of the same is also very important. Water filtration is often confused with purification. However, they are not one and the same. Filtration prevents unwanted particles from passing through, where water purification removes unwanted contaminants from water.
Types of Water Filtration
There are several types of water filtration available for effective use today.
Activated carbon filters are effective for removing odours and bad tastes from the water. In addition, activated carbon filters can remove a wide range of organic compounds. This fact is what makes the carbon filter a popular choice for water pre filtration.
Activated carbon is also very effective in the removal of free chlorine in the feed water to Reverse Osmosis systems. The type commonly used is carbon impregnated with a pore rating of 5 micron. This removes free chlorine and reduces the fouling index to acceptable levels.
Sediment filters offer an effective yet low-cost way to filter water. Water passes downward through sand that has been organised in such a way as to have large particles near the top and small particles near the bottom. Because water moves slowly with only the power of gravity, much contact is made with the filter, allowing fungi, bacteria, organic matter and even some viruses to be removed.
Carbon block filtration uses both adsorptive and slow filtration to filter water. Widely considered to be the best method of water filtration, carbon block filters solve the worry of contaminants being left behind once the water has passed through them.
Advantages and Disadvantages
Water filtration systems are not limited by size as far as the contaminant particles they can remove. As a result, a much higher number of contaminants can be removed by water filtration while retaining healthy minerals.
As well, water filters do not require expensive energy sources to work and waste very little water when compared to other methods.
Unfortunately, water filtration may not remove all unwanted contaminants from water. For example, some filters do not remove chemicals, causing them to remain in the water. Rapid water filters may not allow enough time for water to make contact with the filter, which can also result in contaminants being retained in the water.
As stated previously, the solid block carbon filter uses adsorption to ensure that chemicals as well as other contaminants are removed from water.
