Clean water is a basic need that is very important for human life.
This article will take an in-depth look at the role of pH balancing in domestic water treatment, as well as various related aspects of water treatment systems commonly used in Indonesia. We will explore the different water sources used, the challenges faced, and the solutions available to ensure a safe and high-quality water supply for households.
Understanding Household Water Treatment Systems
Household water treatment systems in Indonesia generally utilize water storage from municipal sources (PDAM) or wells, or sometimes a combination of both. Water from these sources is then pumped through a series of filters or water softeners to remove contaminants such as iron, silica, and other minerals. Some systems also utilize reverse osmosis (RO) technology for further water purification.
For households using well water, the main challenges often faced are high iron and manganese content, as well as potential bacterial contamination due to leaks from septic tanks. On the other hand, PDAM water sourced from rivers can also face contamination issues from household and small industry effluents.
To address these challenges, we have developed a series of water treatment programs to address these challenges.
To address these challenges, many experts recommend the use of whole-house water treatment systems installed at the point of entry of water from either wells or PDAMs. These systems usually consist of multiple treatment stages, including filtration, water softening, and disinfection.
The Role of Chlorine in Water Treatment
One important aspect of water treatment is the use of chlorine as a disinfectant. While some people may not like the smell of chlorine, it is important to understand that this odor is actually a sign of water that has been properly disinfected. In many countries, including overseas, people are accustomed to drinking chlorinated water and are even reluctant to drink water without this distinctive odor.
Chlorine is effective in killing bacteria and other harmful microorganisms that may be present in water. The use of chlorine in PDAM water treatment and household water treatment systems has been proven safe and effective in maintaining drinking water quality. However, for those who remain concerned with chlorine odor or taste, the use of activated carbon filters at the point of use can be a solution to remove residual chlorine before consumption.
Water Quality Challenges in Indonesia
Indonesia faces various challenges related to water quality, especially in certain areas. Some cities in Indonesia face low pH issues, especially in areas with peat soils. Although PDAMs have conducted treatment to adjust the pH, sometimes these adjustments may not be accurate or consistent. For customers using well water in peat areas, the issue of low pH may be more significant.
In addition, some areas also face the issue of high Total Dissolved Solids (TDS), which can affect the taste and overall water quality. Water with high TDS may require further treatment, such as the use of a reverse osmosis system, especially if it is used for drinking water.
Water Treatment Solution for Households
To address various water quality challenges, there are several solutions that can be implemented at the household level:
- Whole House Filtration Systems:These systems are installed at the point of water entry into the home and can remove a variety of contaminants such as sediment, chlorine, and some dissolved minerals. These systems often use polyglass FRP filter tanks which are durable and effective.
- Water Softener: For households with high water hardness issues, a water softener can help reduce the calcium and magnesium content in water. This not only improves the water quality for daily use, but also protects household appliances from damage due to scale buildup.
- Water Softener: For households with high hardness issues, a water softener can help reduce the calcium and magnesium content of water.
- Reverse Osmosis (RO) System: For the highest quality drinking water, an RO system can be a good choice. These systems are highly effective in removing various contaminants, including microplastics. Undersink RO systems such as the Pentair Merlin are becoming a popular choice for domestic kitchens.
- UV disinfection: For added protection against microorganisms, an ultraviolet (UV) disinfection system can be used. This is highly effective in killing bacteria and viruses without altering the taste or odor of the water.
PH Balancing: The Key to Optimal Water Quality
One important aspect of water treatment that is often overlooked is pH balancing. Unbalanced water pH can cause a variety of problems, ranging from bad tasting water to corrosion of pipes and equipment. Therefore, pH balancing is a crucial step in the household water treatment process.
The ideal pH of water for human consumption and household use generally falls within the range of 6.5 to 8.5. Water with a pH below 7 is considered acidic, while above 7 is considered alkaline. Water that is too acidic can cause corrosion of metal pipes and appliances, while water that is too alkaline can cause scale formation and reduce the effectiveness of the disinfection process.
Water that is too acidic can cause corrosion of metal pipes and appliances.
To balance the pH of water, several methods can be used:
- Use of pH Filter Media: Filter media such as Calcite and Corosex can be used to increase the pH of water that is too acidic. These media slowly dissolve in the water, releasing minerals that increase pH and alkalinity.
- Chemical Injection: For larger systems or water with significant pH issues, chemical injection such as soda ash or sodium hydroxide can be used. This requires a proper dosing system, such as a Hydropro dosing pump.
- Aeration:For water with high CO2 content leading to low pH, an aeration process can help remove the CO2 and naturally increase the pH.
It is important to note that pH balancing should be done carefully and monitored regularly. Too drastic or inconsistent changes in pH can cause new problems in the water distribution system.
Essential Components in a Household Water Treatment System
In addition to filters and pH balancing systems, there are several other important components in a household water treatment system that need to be considered:
- Storage Tank: The raw water storage tank, either from a well or PDAM, is an important component in the system. These tanks should be made of safe and durable materials.
- Pumps: Pumps are used to convey water from the source to the treatment system and then throughout the house. Proper pump selection is critical to the efficiency of the system.
- Pressure Vessel: Pressure tanks like the Wellmate are used to ensure consistent water pressure throughout the home without the need to turn on the pump every time a faucet is opened.
- Automatic Valves: Automatic valves are used to control the flow of water through various stages of treatment. These valves should be corrosion resistant and reliable.
- Control Systems: Automated control systems, such as the Aquamatic stager, can be used to efficiently manage valve and pump operations.
Choosing the Right Filtration Media
Choosing the right filtration media is critical to the effectiveness of a water treatment system. Some commonly used filtration media include:
- Activated Carbon: Coal-based activated carbon is very effective in removing chlorine, odor, and bad taste from water.
- Iron Removal Media: For water with high iron content, media such as Birm or manganese greensand can be used.
- Antrasite: Antrasite filter media is effective for removing suspended particles and improving water clarity.
