Clean water is a basic need that is very important for every household.
However, often the quality of available water does not meet the desired 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 household water treatment systems, common problems that are often faced, as well as solutions that can be implemented.
A household water treatment system generally consists of several major components, including a storage tank, pump, filter, water softener, and sometimes a reverse osmosis (RO) system. The main purpose of these systems is to treat water from an available source, be it well water or PDAM water, into water that is safe and convenient for daily use.
The water source used in the system is the well water.
The source of water used in household water treatment systems usually comes from two main sources: well water or PDAM (Regional Drinking Water Company) water. Each of these water sources has its own characteristics and challenges in the treatment process.
Well water, which is widely used in household water treatment systems, comes from either well water or PDAM water.
Well water, which is widely used in areas not covered by the PDAM network, often contains high levels of iron and manganese. In addition, well water is also susceptible to bacterial contamination, especially if there are leaks from nearby septic tanks. On the other hand, PDAM water, which comes from surface water sources such as rivers, sometimes also faces contamination issues from household and industrial waste.
Some households also use water from rivers and other surface water sources.
Some households also use refill water as their source of drinking water. While practical, the use of refillable water also comes with its own risks, such as the potential for microplastic contamination from the plastic bottles used.
.
To address these various water quality issues, comprehensive household water treatment systems are becoming an increasingly desirable solution. These systems are usually installed at the point of entry and are capable of treating the entire water supply entering the home.
The main components of a comprehensive household water treatment system are the following.
Main Components of Household Water Treatment System
An effective household water treatment system usually consists of several main components:
- Storage Tank:Functions to store raw water, either from wells or PDAMs.
- Pump: Used to transport water from the storage tank to the treatment system.
- Filter:Functions to filter solid particles and other contaminants from water.
- Water Softener: Reduces mineral content that causes water hardness.
- Disinfection System:Usually uses chlorine or UV light to kill harmful microorganisms.
- Reverse Osmosis (RO) System: Optional, used for advanced filtration, especially for drinking water.
One of the important components in a water treatment system is the pressure tank or pressure vessel. The Codeline 40E and 40S series pressure vessels are a popular choice for reverse osmosis and other water treatment systems. These tanks help maintain consistent water pressure throughout the system, ensuring optimal water treatment efficiency.
Common Problems in Household Water Treatment Systems
Although household water treatment systems are designed to provide comprehensive solutions, there are some common problems that are often encountered:
1. Iron and Manganese Contamination
Well water often contains high levels of iron and manganese. This can cause the water to be brownish in color, have a metallic taste, and leave stains on clothing and sanitary equipment. To solve this problem, the use of specialized filter media such as manganese greensand Inversand or Birm media from Clack can be an effective solution.

2. Water hardness
Water that contains high levels of calcium and magnesium can cause hardness. This can result in scale formation on appliances and reduce the effectiveness of soaps and detergents. The use of water softener systems with ion exchange resins can solve this problem. Dionix's MUI halal-certified ion exchange resin is a good choice for this need.
3. Microbiological Contamination
The presence of bacteria and other harmful microorganisms in water is a serious threat to health. Disinfection systems using chlorine or UV light are essential to address this issue. Hydropro ultraviolet systems can be an effective option for water disinfection.
4. Unpleasant Odor and Taste
Water that has an unpleasant odor or taste is often caused by the presence of organic compounds or excessive chlorine. The use of activated carbon filters can help remove these odors and tastes. Calgon's coal-based activated carbon is a good option to solve this problem.
5. Unstable Water Pressure
Fluctuations in water pressure can affect the overall performance of a water treatment system. The use of pressure tanks can help stabilize water pressure. Wellmate pressure storage tanks are a reliable solution to this problem.
Solutions to Common Problems in Household Water Treatment Systems
To solve the various problems that have been mentioned above, here are some solutions that can be implemented:
1. Multilevel Filtration System
The use of a multilevel filtration system can help address multiple water quality issues at once. These systems usually consist of:
- Sediment filter to filter out coarse particles
- Activated carbon filter to remove odor and taste
- Specialized filters such as manganese greensand to remove iron and manganese
Pentair's FRP Polyglass filter tanks can be used as containers for these various filter media.
2. Water Softening System
To solve water hardness problems, water softening systems using ion exchange resins are very effective. These systems replace calcium and magnesium ions with sodium ions, thereby reducing water hardness. Pentair's Fleck automatic filter valves can be used to control this water softening process.
3. Disinfection System
To ensure water is free from microbiological contamination, disinfection systems are essential. This can be:
- Chlorination system using a dosing pump
- Ultraviolet (UV) system
Hydropro dosing pumps can be used for chlorination systems, while UV systems can use products as previously mentioned.
4. Reverse Osmosis (RO) System
For advanced drinking water treatment, reverse osmosis systems are highly effective in removing various contaminants, including microplastics. Pentair's Merlin undersink RO system is a good solution for household drinking water needs.
5. Routine Maintenance
Routine maintenance is essential to ensure the water treatment system is functioning optimally. This includes:
- Periodic filter replacement
- Cleaning and disinfection of storage tanks
- Checking and calibration of the dosing system
- Leak inspection and repair if required
The use of high-quality components such as Pentair's Pentek filter cartridges can help ensure consistent system performance.
Special Considerations for Different Types of Water Sources
A household water treatment system needs to be customized according to the type of water source used:
1. Well Water
For well water, the main focus is usually on iron, manganese, and bacteria removal. A common treatment sequence is:
- Aeration to oxidize iron and manganese
- Filtration using specialized media such as manganese greensand
- Water softening if required
- Disinfection using chlorine or UV
2. PDAM water
For PDAM water, the treatment system is usually simpler:
- Sediment filtration to remove fine particles
- Activated carbon filtration to remove excess chlorine and improve taste
- Water softening if required
3. RO System for Drinking Water
For drinking water needs, an RO system can be added as the final stage of treatment. It is very effective at removing various contaminants, including microplastics that may be present in refill water.
