How to Choose the Best RO System for a Refillable Water Business

Water is a basic human need that cannot be replaced. In Indonesia, water refill business has become a popular solution to fulfill people's drinking water needs.

However, with the increasing awareness of the importance of drinking water quality, water refill businesses are required to be able to provide water that is not only safe, but also of high quality. One technology that can help achieve high water quality standards is the Reverse Osmosis (RO) system. In this article, we will take an in-depth look at how to choose the best RO system for a water refill station, as well as the various important aspects that need to be considered in running this business.

The water refill business in Indonesia has grown rapidly in recent years. Many entrepreneurs are interested in getting into this business due to the huge market potential and people's need for quality drinking water. However, not all water refill businesses operate with the same standards. Some use water that comes from the mountains (although this claim cannot always be verified), while others use water from municipal sources or wells.

Regardless of the water source.

Regardless of the water source, water refill businesses have a huge responsibility to ensure that the water they sell is safe and fit for consumption by the public. They must understand that the problems faced in water treatment for refill businesses are not much different from water treatment for domestic use, but on a larger scale and with heavier responsibilities.

One of the most important aspects of water treatment for refill businesses is the treatment of water for household use.

One of the most important aspects of water treatment for refill businesses is the disinfection process. This is a crucial step to remove harmful microorganisms that can cause illness. In addition, businesses must also ensure that the water they produce is free of harmful dissolved substances, which ordinary filters may not be able to remove. This is where the role of Reverse Osmosis (RO) systems becomes very important.

RO systems are capable of removing a wide range of contaminants, including solutes that are difficult to remove by conventional filtration methods. However, choosing the right RO system must consider various factors, including the available budget. Water refill businesses should also pay attention to the aspects of proper cleaning and maintenance of the system to maintain the quality of the water produced.

It is important to note that water refill businesses fall under the category of commercial customers, so the use of RO systems for household use is not recommended. There are three levels of RO systems available in the market: Residential, Commercial, and Industrial. Each of these tiers is designed to handle different workloads.

Water treatment systems for water refill businesses fall under the category of commercial customers.

A water treatment system for a refill business usually consists of several main components, namely water storage, filters, RO system, and UV and ozone units. The use of ozone as an additional disinfection method has the advantage of having a residual effect that can help sanitize water. Unlike the use of chlorine, ozone does not leave an odor or taste in the water, making it more preferred by consumers.

In choosing the best RO system for a water refill station, there are several key factors to consider. Let us discuss in more detail about these important aspects.

Production Capacity

One of the most important factors in choosing an RO system for a water refill business is the production capacity. You need to consider how much water will be produced each day to meet customer demand. Commercial RO systems usually have a larger production capacity compared to residential systems.
