Clean water is a basic need that is very important for every household.
However, the quality of available water does not always meet the desired health and comfort standards. Therefore, household water treatment systems are becoming an increasingly popular solution to ensure the availability of clean and safe water at home. In this article, we will take an in-depth look at the components of a household water treatment system, with a special focus on the sediment filter as one of the key elements in the water purification process.
Water purification is an important part of the water treatment process.
Modern domestic water treatment systems are designed to address a variety of water quality challenges, whether sourced from well water or PDAM water. Each water source has different characteristics and potential contaminants, requiring specific treatment approaches. For example, well water often contains high levels of iron and manganese, and is potentially contaminated with bacteria from leaking septic tanks. On the other hand, PDAM water that comes from rivers may be polluted by household and industrial waste, and contain residual chlorine that can affect the taste and odor of the water.
In the face of these challenges, a comprehensive domestic water treatment system usually consists of several treatment stages. Starting from raw water storage, pumping, filtration, water softening, to disinfection. Each stage plays an important role in ensuring that the quality of water produced meets the health and comfort standards of the users.
Main Components of Household Water Treatment System
1. Raw Water Storage Tank
A raw water storage tank serves as a reservoir for water from the source, be it a well or PDAM. This tank ensures stable water availability for the next treatment process. The choice of material and size of the tank must be adjusted to the needs and conditions of the house.
2. Water Pump
Water pumps play an important role in transporting water from storage tanks to various stages of treatment. Proper pump selection, such as the Flint and Walling RO pump, can improve overall system efficiency.
3. Sediment Filter
The sediment filter is the first line of defense in a water treatment system. Its main function is to filter out coarse particles such as sand, silt, and other impurities. This filter is critical to protecting other system components from damage and extending the overall life of the system.
4. Activated Carbon Filter
Active carbon filters are effective in removing odors, bad tastes, and organic compounds dissolved in water. Products such as coal-based activated carbon from Calgon are often used for this purpose.
5. Water Softener System
Water softening systems are used to reduce water hardness by removing minerals such as calcium and magnesium. This is especially important for areas with hard groundwater, which can cause scaling in appliances and pipes.
