How to Set a Maintenance Schedule for Water Treatment Systems

Water is a very important resource for human life.

In Indonesia, the water refill business has become a popular solution to fulfill people's drinking water needs. However, with increased popularity comes greater responsibility for water refill business owners to ensure the quality and safety of their products. One crucial aspect of running a successful and responsible water refill business is proper and regular maintenance of the water treatment system.

The water refill business in Indonesia faces unique challenges. Some entrepreneurs purchase water from sources claimed to be from the mountains, while others use municipal water or well water. Regardless of the source, all water refill businesses face issues similar to household water treatment systems, but with the added responsibility of serving the community well.

A water treatment system for a refill business typically consists of several key components: water storage, filters, possibly a reverse osmosis (RO) system, as well as disinfection systems such as ultraviolet (UV) and ozone. Each of these components requires proper care and maintenance to ensure optimal performance and consistent water quality.

Disinfection is the most critical step in the water treatment process, as it is the primary defense against microbiological hazards that can cause disease. Furthermore, the removal of unwanted solutes, which cannot be removed by ordinary filters, is also important. RO systems can address these issues, although their implementation depends on the available budget.

Proper cleaning is also an important aspect of water treatment system maintenance. Considering that the volume of water treated by refill businesses is much larger than household use, it is important to use commercial systems instead of residential systems. There are three levels of systems: Residential, Commercial, and Industrial, each with progressively higher loads.

In this article, we will take an in-depth look at maintenance schedules for high-use water treatment systems in the context of water refill businesses in Indonesia. We will explore the various aspects of maintenance, from routine cleaning to component replacement, as well as the importance of maintaining consistent water quality. Let's embark on a journey to understand how to keep a water treatment system functioning optimally and producing safe, high-quality water for consumers.

Understanding Water Treatment System for Refill Business

Before we dive into the maintenance schedule, it is important to understand the main components of a water treatment system that is commonly used in water refill businesses in Indonesia.

1. Water Storage

The water storage tank is the first component in the system. Water from the source (be it mountain water, city water, or well water) is stored here before entering the treatment process. This tank should be made of food-safe materials and resistant to algae or bacteria growth. Wellmate's Pressure Tank is one option that can be considered for efficient and hygienic water storage.

2. Filtration System

A filtration system usually consists of several stages:

• Sediment Filter: Removes large particles such as sand, silt, and dirt.
• Sediment Filter.
• Active Carbon Filter: Removes unwanted chlorine, odors, and tastes. Calgon's coal-based activated carbon is a good choice for this stage.
• Fine Filter: Removes smaller particles. Hydropro's MUI halal-certified melt-blown cartridge can be a good choice.

3. Reverse Osmosis (RO) System

RO systems are one of the most effective methods for removing dissolved contaminants, including salts, minerals, and organic substances. These systems use semi-permeable membranes to filter water on a molecular level. DuPont TAPTEC reverse osmosis membranes specially designed for bottle refilling stations can be the right choice for water refill businesses.

4. Disinfection System

The final stage in water treatment usually involves disinfection to ensure the water is free of harmful microorganisms. Two commonly used methods are:

• Ultraviolet (UV): UV light kills microorganisms by damaging their DNA. The Hydropro ultraviolet disinfection system is one of the options available in the market.
• Ultraviolet disinfection.
• Ozonization: Ozone is a powerful disinfectant that also helps remove odors and tastes. Ozone has a residual effect, which means it continues to work after the treatment process, helping to keep the water clean during storage.

5. Control and Monitoring System

Modern systems are often equipped with automated control and monitoring devices. These can include Create pH and conductivity analyzers to monitor water quality in real-time.

Understanding the components of a modern system can help you understand the components of the system.

Understanding these components and their functions is essential in designing an effective maintenance schedule. Each component has different maintenance needs and different frequencies. Let's take a more detailed look at the maintenance schedule for high usage water treatment systems.

Maintenance Schedule for High Use Water Treatment System

Regular and timely maintenance is key to ensuring the water treatment system continues to function optimally and produce consistently high-quality water. Here is a suggested maintenance schedule for various system components:

1. Daily Maintenance

• Check the water pressure at each filtration and RO stage. A significant change in pressure could indicate a problem with the filter or membrane.
• Check the water pressure at each filtration and RO stage.
• Check the quality of water produced using TDS (Total Dissolved Solids) and pH meters.
• Check for leaks at all stages of filtration and RO.
• Check for leaks throughout the system.
• Clean the area around the system to prevent accumulation of dust and dirt.

2. Weekly Maintenance

• Clean the water storage tank using a food-safe disinfectant solution.
• Check and clean the pre-filter.
• Check and clean the sediment pre-filter. This frequency may need to be increased if the water source has high sediment levels.
• Check and clean the sediment pre-filter.
• Check the UV system and clean its quartz tube if necessary.
• Calibrate pH and conductivity meters.

3. Monthly Maintenance

• Replace sediment and activated carbon filters. NSF-certified Pentair Pentek filter cartridges can be a good choice for regular replacement.
• Check and clean the valves in the system, including the corrosion-resistant Aquamatic automatic valves.
• Perform a backwash on the multimedia filter if applicable.
• Check and clean the ozonation system.

4. Quarterly Maintenance

• Perform chemical cleaning on RO membranes to remove fouling and scaling. Use the cleaning agent recommended by the membrane manufacturer.
• Replace the UV lamp if required.
• Replace the UV lamp if needed. UV lamps usually have a lifetime of about 9000 hours or one year.
• Check and calibrate the RO membrane.
• Check and calibrate all sensors and measuring instruments in the system.

5. Annual Maintenance

• Replace the RO membrane if its performance has significantly degraded. RO membranes typically have a service life of 3-5 years, depending on feed water quality and regular maintenance.
• Conduct a thorough inspection of the entire system, including tank integrity checks.
• Conduct a thorough inspection of the entire system, including integrity checks of tanks, pipes, and connections.
• Recalibrate or replace aging gauges and sensors.
• Evaluate overall system efficiency and consider upgrades if necessary.

6. Performance Based Maintenance

In addition to the regular schedule, some maintenance should be performed based on system performance:

• If the differential pressure at the filter increases by more than 10-15% of the normal value, it indicates the need for filter replacement.
• If RO water production decreases by more than 10-15% or salt rejection decreases, this indicates the need for membrane cleaning or replacement.
• If the quality of the produced water decreases (e.g., increased TDS), check and troubleshoot immediately.

It is important to note that this schedule is a general guide. The exact frequency of maintenance may vary depending on feed water quality, production volume, and specific operating conditions. Always follow the recommendations of the equipment manufacturer for optimal maintenance.
