Let’s have a look at 2 commonly-seen water treatment services – cooling tower water treatment and swimming pool water treatment.
There are 2 basic types of cooling tower water treatment: Filter-Reactor (also called “filter-chloride”) – A filter-reactor uses a low-pressure, air-driven, sand filter to remove the larger suspended solids. The treated water then flows through a high-pressure reactor where the remaining suspended solids are removed by the reaction with chlorine.
Reverse Osmosis (RO) – This is an advanced cooling tower water treatment process that uses a semi-permeable membrane to remove many of the pollutants from the water, including calcium, magnesium, iron, ammonia, nitrate and organic compounds. The treated water is then recycled back into the system. Depending on the type of treatment plant you choose, the design and installation will vary. Some plants are modular, which means that they can be broken down into separate components and moved around to different locations as needed.
Moving on to swimming pool water treatment. Some removes impurities using sand as a filter medium. One problem associated with the use of sand is that it can clog the filter medium. This causes the swimming pool water treatment system to work less efficiently and the pool water to become dirty again. Sand can also cause the filter to break down over time, which will lead to a buildup of impurities in the pool water. This buildup of impurities can lead to an increased risk of disease and bacteria growth in the pool water.
