The water refill business has become very popular in Indonesia in recent years. This phenomenon emerged in response to the public's need for affordable and easily accessible drinking water. Many small and medium entrepreneurs have capitalized on this opportunity by setting up water refill depots in various strategic locations. However, behind the success of this business, there is a great responsibility that must be shouldered by business actors to ensure the quality and safety of the drinking water products they produce.

A good understanding of this aspect is very important considering that the improper use of chemicals can have a serious impact on the quality of the water produced and even potentially jeopardize the health of consumers.

Before we dive into this topic, we will explore the topic of water quality and safety.

Before we dive into the main topic, it is important to understand the context of the water refill business in Indonesia. Some depots claim to use water that comes from the mountains, although these claims cannot always be verified. Meanwhile, many other depots use water from urban sources or wells. Regardless of the source, the challenges faced by these entrepreneurs are actually not that different from treating water for domestic use. However, as commercial service providers, they have a greater moral and legal obligation to ensure that the water they produce is safe for consumption by the public at large.

One of the most important aspects of water treatment is that it is safe to drink.

One of the most important aspects of water treatment is the disinfection process. This is a crucial step to remove pathogenic microorganisms that can cause disease. In addition, water refill depots must also pay attention to the content of dissolved substances in the water that cannot be removed by ordinary filters. To solve this problem, many depots use reverse osmosis (RO) technology, which is capable of filtering out various contaminants down to the molecular level.

However, the use of advanced technology such as RO is not always possible.

A water treatment system in a depot is the most important part of the water treatment process.

Water treatment systems in refill depots generally consist of several main components, including raw water storage tanks, various types of filters, RO units (if applicable), and disinfection systems using ultraviolet light (UV) and ozone. The use of ozone as a disinfectant has the advantage of having a residual effect that can help keep water clean during the storage and distribution process. Unlike chlorine, which is often used in PDAM water treatment, refill depots tend to choose ozone because it does not leave an odor or taste in the water.

Proper chemical management is a crucial aspect of water refill depot operations. Chemicals are used in various stages of water treatment, from the initial filtration process to the final disinfection. Improper use can result in water contamination, equipment damage, and even health risks for workers and consumers.

One of the basic principles in proper chemical management is that the chemicals must be properly managed.

One of the fundamental principles in water management is that matter cannot be created or destroyed through ordinary chemical processes. This means that everything that goes into the system must be in balance with what comes out. This principle applies to all water that enters, exits, or remains in equipment or systems. It also applies to any chemical constituents originally present in the water and any chemical constituents that may be added to treat it.

In the context of water refill depots, some commonly used chemicals include:

  1. Chlorine or chlorine compounds for initial disinfection
  2. Coagulant materials such as alum or polymers to remove suspended particles
  3. Activated carbon to remove odor, taste, and organic compounds
  4. Ion exchange machine for water softening or demineralization
  5. Chemicals for pH adjustment such as caustic soda or sulfuric acid
  6. Ozone or peroxide compounds for final disinfection

Each of these chemicals has its own characteristics and risks that should be well understood by depot operators. For example, chlorine is an effective disinfectant but can react with organic compounds to form harmful byproducts. Activated carbon is highly effective at removing organic contaminants, but if not replaced regularly can become a breeding ground for bacteria.

To ensure safe and effective chemical management, water refill depots need to pay attention to several important aspects:

  1. In-depth understanding of the properties and risks of each chemical used
  2. Proper storage according to the characteristics of each material
  3. Use of appropriate personal protective equipment (PPE) when handling chemicals
  4. Adequate training for staff handling chemicals
  5. Good documentation system for recording chemical usage and stock
  6. Emergency response plan to deal with chemical-related spills or accidents

One important aspect of chemical management is the selection of the right equipment. For example, for chemical injection, depots can use Aquamatic injectors specifically designed for water treatment applications. This equipment ensures accurate and efficient mixing of chemicals, reducing the risk of overdosing or underdosing that could affect water quality.

In addition, the use of corrosion-resistant Aquamatic automatic valves can help control the flow of water and chemicals with great precision, reducing the risk of human error and improving operational efficiency.

A good understanding of chemical management is not only important for maintaining water quality, but also for ensuring compliance with applicable regulations. In Indonesia, water refill depots must comply with various regulations, including the Minister of Health's Regulation on Drinking Water Quality Requirements and Sanitary Hygiene of Drinking Water Depots.
