However, with the increasing awareness of the importance of good water quality, many families in Indonesia are starting to consider installing a water treatment system in their homes. One question that often arises when deciding to use a water treatment system is how much electricity it will consume. This article will take an in-depth look at power consumption in household water treatment systems, as well as provide insights on how to select and operate an efficient system.
In this modern era, the availability of clean, safe water for consumption has become increasingly important. Although many areas in Indonesia have access to PDAM water, the quality of water provided does not always meet the desired standards for direct consumption. In addition, many households still rely on well water sources that may contain contaminants such as iron, manganese, or bacteria. Therefore, household water treatment systems are becoming an increasingly popular solution.
However, before deciding to install a water treatment system, it is important to understand the power usage implications that will arise. Excessive power consumption will not only increase electricity bills, but can also negatively impact the environment if not managed properly. This article will discuss various aspects related to power consumption in household water treatment systems, ranging from the types of systems commonly used, factors that affect power consumption, to tips for optimizing energy efficiency.
One problem that often occurs in the planning of household water treatment systems is over-specification. For example, it is not uncommon to find a system with a capacity of 7 m3/hour for a family of 5 (which can increase to 10-12 people if servants are included). A capacity of this size is actually unnecessary, as it will only fill the above storage tank in half an hour per day. Overspecification like this not only wastes energy, but also increases initial investment costs unnecessarily.
In this article, we will explore various aspects of household water treatment systems, including key components, commonly used treatment processes, and how each of these elements contributes to total power consumption. We will also discuss the importance of choosing a system that suits the specific needs of the household, as well as how to optimize system operation to achieve maximum energy efficiency.
Before we discuss more about power consumption, it is important to understand the main components that are commonly found in household water treatment systems. These systems typically consist of:
Each of these components has a contribution to the total power consumption of the system. The pump, for example, is often the component that consumes the most electricity. Therefore, efficient pump selection and proper operation settings are key in optimizing energy consumption.
Power consumption in domestic water treatment systems is influenced by various factors, including:
Understanding these factors is important in designing and operating an energy-efficient water treatment system. For example, for a home with a relatively clean PDAM water source, it may be sufficient to use a simple filtration system with a cartridge filter and UV disinfection, which is much lower in power consumption than a full RO system.
To give you a more concrete idea, let's take a look at the estimated power consumption for some commonly used types of household water treatment systems:
Keep in mind that these figures are only rough estimates and actual power consumption will vary depending on the specifications of the equipment used, water usage patterns, and other factors. In addition, systems do not always operate at full capacity all the time, so the daily average power consumption is usually lower than the above figures.
To optimize power consumption in domestic water treatment systems, some of the following strategies can be applied:
In addition, consider the use of energy-efficient technologies such as ultra low pressure (ULP) RO membranes that can operate at lower pressures, thereby reducing pump power consumption.
The type of water source used will affect the design of the treatment system and consequently the power consumption. Here are some special considerations:
Choosing the right treatment technology according to the characteristics of the water source can help optimize power consumption. For example, for well water with high iron content, the use of Birm media that does not require chemical regeneration can be more energy efficient compared to conventional ion exchange systems.
Technological developments continue to bring innovations in the field of water treatment that can improve energy efficiency. Some examples of such innovations include:
Although some of these technologies may have higher initial investment costs, the long-term energy savings can result in a significant return on investment, especially for large-scale systems or in areas with high electricity rates.
In selecting and operating a household water treatment system, it is important to consider economic and environmental aspects in addition to power consumption. Some factors to consider:
To reduce environmental impact, consider using Halal certified ion exchange resin which is more environmentally friendly in the regeneration process.
Household water treatment is an important investment to ensure the availability of clean and safe water for families. However, it is important to consider power consumption as one of the main factors in system selection and operation. By understanding the components of the system, factors that affect power consumption, and optimization strategies, we can achieve a balance between desired water quality and energy efficiency.
Some key points to keep in mind:
With the right approach, we can enjoy the benefits of high-quality clean water while maintaining energy efficiency and minimizing environmental impact. Remember that every household has unique needs, and consultation with a water treatment professional can help in choosing the most suitable solution.
Not always. Some simple water treatment systems can operate without electricity, utilizing gravity or existing water pressure. Examples include gravity-flow activated carbon filters or ceramic filtration systems. However, more advanced systems such as reverse osmosis or ultrafiltration generally require electricity to operate pumps and other components. For households looking to reduce dependence on electricity, a combination of a passive system for initial treatment and an electrically powered system for the final stage could be a good solution.
Some indicators that can indicate excessive power consumption in household water treatment systems include:

"In much of Europe, there may be complaints about the cost of water, but it is generally accepted that it is essential to have the highest quality water, almost regardless of cost. Notwithstanding this, in March 2011 it was stated by the EU, that for drinking water in small supplies (serving less than 5000 people) no more than 60% of the small water supply zones deliver water which is entirely compliant with the requirements of the Directive (according to a study produced at the Commission's request)."
