With an in-depth understanding of this topic, it is hoped that entrepreneurs and aspiring entrepreneurs in the water refill field can make informed decisions in selecting and implementing a water treatment system for their business.

Understanding Water Sources and Challenges

The first step in choosing the right water treatment system is to understand the characteristics of the water source to be used. In Indonesia, water refill businesses generally use three main types of water sources: mountain water, well water, and PDAM (Perusahaan Daerah Air Minum) water.

1. Mountain Water: Many water refill entrepreneurs claim to use mountain water as their water source. Mountain water is often considered a pure and high-quality water source. However, keep in mind that not all water claimed to come from the mountains is truly pure or safe for consumption without further treatment. Mountain water can also be contaminated by various factors, such as human activities in the upstream area or environmental pollution.

2. Well Water: Well water is a commonly used source, especially in areas that do not have access to piped water. The quality of well water can vary greatly depending on the surrounding geological and environmental conditions. Well water may contain high amounts of dissolved minerals, heavy metals, or even microbiological contaminants.

3. Tap water: Water supplied by the PDAM has generally gone through a basic treatment process. However, the quality may vary depending on the source of raw water and the effectiveness of the treatment system used by the local PDAM. In addition, contamination may occur during the distribution process through old or damaged pipes.

Each of these water sources has unique challenges and characteristics that must be considered in designing a water treatment system. For example, mountain water may require simpler filtration while still requiring effective disinfection. Well water may require more intensive treatment to remove excess minerals or other contaminants. Meanwhile, tap water may require additional treatment to upgrade its quality to drinking water standards.

It is important to conduct a thorough source water quality analysis before designing a treatment system. This analysis should include physical (such as turbidity and color), chemical (such as pH, hardness, and metal content), and microbiological (such as coliform bacteria) parameters. The results of this analysis will form the basis for determining the type and level of treatment required.

Main Components of Water Treatment System

After understanding the characteristics of the water source, the next step is to design a suitable water treatment system. A water treatment system for a refill business generally consists of several main components:
