Understanding Water Sources and their Contaminants

Before we discuss more about household water treatment, it is important to understand the various water sources commonly used by Indonesians, as well as the contaminants they may contain.

1. PDAM water

Drinking water is the main source of water for most urban communities. This water usually comes from rivers or reservoirs that have been treated at water treatment plants. Despite its treatment, PDAM water can still contain various contaminants, including:

• Chloramine and residual chlorine
• Heavy metals such as lead and copper
• Microplastics
• Bacteria and viruses that escape the disinfection process
• Organic compounds that can form trihalomethanes (THMs) when reacting with chlorine

2. Well Water

For people who live in areas not covered by PDAM services, well water is the main alternative. However, well water can also contain various contaminants, such as:

• High levels of iron and manganese
• Coliform bacteria and E. coli from septic tank seepage
• Nitrates from agricultural fertilizers
• Arsenic and other natural contaminants

3. Rainwater

In some areas, rainwater harvesting is an alternative water source. Although relatively clean, rainwater can be contaminated by:

• Air pollutants
• Dirt from roofs and gutters
• Microorganisms that develop in storage tanks

Understanding the water source and its potential contaminants is critical in designing an effective household water treatment system. Each water source has unique characteristics that require different treatment approaches.

Water Treatment Technologies to Address Chloramines

To solve the chloramine problem in tap water, there are several water treatment technologies that can be used. Here are some of the most effective methods:

1. Activated Carbon Filtration

Activated carbon is one of the most effective filtration media for removing chloramine from water. The process works through adsorption, where chloramine molecules are trapped in the pores of activated carbon. Calgon's coal-based activated carbon is one of the highly effective products for this purpose.

2. Reverse Osmosis (RO)

Reverse osmosis systems use semi-permeable membranes to filter out various contaminants, including chloramines. Pentair Merlin's undersink RO system is an example of a product suitable for household use.

3. Ultrafiltration

While not as effective as RO in removing chloramines, ultrafiltration can reduce chloramine levels while retaining essential minerals in water. The Asahi ultrafiltration membrane is one option available in the market.

4. Ion Exchange

Ion exchange machines can be used to remove chloramine through a chemical process. Dionix's MUI halal certified ion exchange machine is a good choice for Muslim consumers.

5. Ultraviolet (UV) Disinfection

While it does not remove chloramines directly, a UV system can help inactivate microorganisms that may have escaped the chlorination process. A Hydropro UV system can be a good addition to a household water treatment system.

Designing a Comprehensive Household Water Treatment System

To effectively address the issue of chloramines and other contaminants, a comprehensive approach in designing a household water treatment system is required. Here are the steps that can be followed:

1. Water Quality Analysis

The first step is to conduct a water quality analysis to determine the type and level of contaminants present. This will help in determining the type of treatment required.

2. Selection of the Right Technology

Based on the results of the analysis, select the most suitable combination of technologies. For example, for PDAM water with high chloramine levels, a combination of activated carbon filtration and RO may be the ideal choice.

3. System Design

Design a water treatment system that includes:

• Raw water storage tank
• Distribution pump
• Sediment filter to remove coarse particles
• Activated carbon filter to remove chloramines and organic contaminants
• RO or ultrafiltration system
• Treatment water storage tank
• UV system for final disinfection

4. Selection of Quality Components

Use high-quality components to ensure system performance and durability. Some recommended products include:

• Polyglass FRP filter tank from Hydropro
