5 stage reverse osmosis system

Types of 5 stage reverse osmosis system

The 5 stage reverse osmosis system is a popular type of water filtration. It effectively eliminates numerous impurities, such as heavy metals, bacteria, viruses, pesticides, and salts. Models with five stages are compact, making them ideal for various settings. There are several models, such as the tankless model, countertop model, and under-sink model.

• Tankless Reverse Osmosis System

  This model has a filter and faucet. It is installed close to the water supply. One benefit of a tankless model is that it filters and dispenses water simultaneously. This usually reduces waste and improves the water's taste. Also, installation is easy because the setup is quick, and it doesn't need a storage tank. Tankless models are compact and environmentally friendly. However, they may lack some filtration features. Experts recommend allowing the filtered water to settle for some hours before using it. The taste might improve better because of the minerals that are expected to return to the water.

• Countertop Reverse Osmosis System

  There are two subtypes: semi-permanent and portable countertop systems. Portable systems are good for traveling or working in diverse locations. They filter water using a pressure created by the user. The pressure can be reduced by inserting a filter into a container. Semi-permanent systems are more durable than the portable ones. The water flows from the source hose into the system, and then a tube brings the filtered water out. The hose and tube are usually connected, so they can be interchanged. This makes it easy to move the entire system to another location. Both the portable and semi-permanent models are easy to install. They don't need electricity, and the waste water can be used for other tasks. However, installation takes time, and they are less permanent than other systems.

• Under Sink Reverse Osmosis System

  Like the tankless system, the under-sink model also comes with a filter and faucet. It is installed underneath the sink in the kitchen. Under sink systems filter large amounts of water and store them. Because it is hidden, it maximizes space on the countertop. This makes it suitable for areas with limited countertop space. It also provides water for cooking, drinking, and other tasks. On the other hand, installation is difficult because the installer has to connect the system to the plumbing system under the sink. It also requires regular maintenance like checking for leaks, replacing filters, and cleaning the storage tank. This model comes with a secondary faucet, which it can easily connect to the sink.

Function and Features

Like any typical reverse osmosis system, the five-stage system has specific fundamental purposes and features.

The primary use of the system is to filter water and make it safer to consume. The following features help achieve this:

• Micron Pre-Filters: The first two stages of a 5-stage filtration system include pre-filters that use microscopic membranes to remove some contaminants. While the first filter removes bigger particles such as silt, sand, and dust, the second filter, made of activated carbon, eliminates VOCs, chlorine, and other substances that can harm the carbon block filter in the subsequent stage.
• RO Membrane: The membrane applies pressure to remove dissolved solids, heavy metals, and pathogens from the water. Around 90 to 99% of such impurities are usually removed. The membrane also helps remove impurities that cause bad tastes and smells from the water.
• Post-Carbon Filter: After reverse osmosis, the water may still contain some bad tastes or smells due to the existence of tiny quantities of dissolved solids. The water also needs to gain back any lost minerals. The post-carbon filter, which normally consists of activated carbon, absorbs any remaining impurities and replenishes the water's minerals, including calcium and magnesium.
• Mineral Filter: Not all purification systems have a mineral filter, but many include it as their fifth stage. Its purpose is to enhance the mineralization of the filtered water. It also improves the flavor and quality of the water so that users may enjoy it more and stay healthy. The mineral filter usually contains natural rock minerals. It is considered an important part of the filtration system because, apart from improving taste, it helps balance the water's pH, which may have become unbalanced during the filtering process.

Applications of 5 stage reverse osmosis system

A 5-stage reverse osmosis system is one of the most potent water filtration systems broadly used to eliminate unwanted ions, pathogens, and other impurities from water. This system has several uses beyond providing clean drinking water for homeowners. Here are some significant applications of a 5-stage reverse osmosis system:
