Function of Performance Monitoring System for Refill Water Business

Refillable drinking water has become an integral part of Indonesians' daily lives.

With the increasing awareness of the importance of safe and quality drinking water, the refillable water depot business has grown rapidly across the country. However, despite its popularity, the industry faces major challenges in ensuring the quality and safety of their products. This article will take an in-depth look at the importance of Performance Monitoring System in the refill water business to produce optimal and safe output for consumers.

The refill water business in Indonesia has unique characteristics. Some depots claim to use water from the mountains (although this claim cannot always be verified), while others use water from urban sources or wells. Regardless of the source, the challenges faced by refill water entrepreneurs are very similar to those faced by household water treatment systems, but with the added responsibility of serving the community to a higher standard.

One of the most important aspects of a refill water business is ensuring an effective disinfection process. This is a major line of defense against microbiological hazards that can directly threaten the health of consumers. In addition, refill water entrepreneurs must also be aware of harmful solutes that cannot be removed by ordinary filters. Reverse Osmosis (RO) technology can be a solution to this problem, although its implementation depends on the available budget.

Cleanliness and sanitation are also major concerns in this industry. Given the scale of their operations, refill water depots should not use systems designed for domestic use. There are three tiers of systems to consider: Residential, Commercial, and Industrial, each with a higher load capacity.

Water treatment systems in refill depots usually consist of a few main components: water storage, filters, RO systems (if budget allows), as well as UV and ozone units for disinfection. The use of ozone has an advantage due to its residual effect that aids sustainable sanitation. Generally, refill water depots do not add chlorine and prefer ozone because of its odor that will dissipate after a while.

Importance of Performance Monitoring System

In the context of a refillable water business, a performance monitoring system is key to ensuring consistent and safe product quality. This system involves not only checking the final water quality, but also monitoring each stage of the treatment process. Here are some important aspects of a performance monitoring system for refill water businesses:

1. Source Water Monitoring

The first step in ensuring refill water quality is to closely monitor the water source. This involves regular testing of the physical, chemical and microbiological parameters of the raw water. The use of pH and conductivity analyzers can help in quick monitoring of source water quality. Sudden changes in these parameters can be an early indication of a problem in the source water.

2. Filtration System Evaluation

The filtration system is a critical component in refill water treatment. Monitoring differential pressure in cartridge filters and RO membranes can provide information on filter efficiency and condition. A significant increase in differential pressure indicates the need for filter replacement or cleaning. The use of high-quality cartridge filters can improve filtration efficiency and extend maintenance intervals.

3. Reverse Osmosis Process Monitoring

For depots using RO systems, monitoring the performance of the RO membranes is essential. This involves measuring the flow rate, operating pressure, and permeate water quality. A decrease in flow rate or an increase in operating pressure could indicate fouling of the membranes. The use of high-quality RO membranes can improve the efficiency and durability of the system.

4. Disinfection Control

Monitoring the effectiveness of the disinfection process, whether using UV or ozone, is crucial. For UV systems, this involves checking lamp intensity and contact time. For ozone systems, dissolved ozone concentration and contact time need to be closely monitored. The use of a reliable UV system can ensure effective and consistent disinfection.

5. Final Water Quality Testing

Final water quality monitoring involves regular testing of microbiological, chemical, and physical parameters. This includes testing for coliform bacteria, TDS (Total Dissolved Solids), pH, and other parameters according to standards set by health authorities.

6. Hygiene and Sanitation Monitoring

This aspect involves regular checks on the cleanliness of equipment, filling areas and employee hygiene practices. The use of corrosion-resistant filter tanks can help keep the system clean and prevent contamination.
