How Does a Reverse Osmosis Filter System Work?

Looking for a water filter system that provides quality drinking water?

Many people depend on a limited number of water sources; unfortunately, most are not clean or healthy. Fortunately, a reverse osmosis filter system offers an effective solution for purifying home drinking and cooking water.

Aqua Hygiene Company, a reputable water filter system solutions provider, offers detailed information to help you make an educated and quick choice regarding your water needs. Let’s explore reverse osmosis’s depth in the below post and discover how it works.

What is the concept behind a reverse osmosis filter system?

A reverse osmosis filter system is designed to filter water using a semi-permeable membrane. This innovative filtration technique effectively eliminates contaminants from water. This water system operates on the principle that water flows from areas of high concentration to low concentration to reach equilibrium.

A reverse osmosis system is a barrier by employing a semi-permeable membrane, allowing only pure water molecules to pass through while blocking impurities such as chemicals, minerals, and bacteria. As a result, this process makes clean and safe drinking water devoid of toxic substances.

What does a reverse osmosis filter system remove?

It removes various substances from tap water, including:

  • Sodium
  • Chloride
  • Copper
  • Chromium
  • Lead

It can also reduce the amounts of

  • Arsenic
  • Fluoride
  • Radium
  • Sulfate
  • Calcium  
  • Magnesium
  • Potassium
  • Nitrate
  • Phosphorous

Highly effective in removing protozoa, bacteria, and viruses, although relying solely on it to filter out all bacteria and viruses is not recommended.

Why do some reverse osmosis filter systems need a tank?

Reverse osmosis filter systems require a tank for several reasons:

  1. Water Accumulation:

Reverse osmosis systems work slowly, filtering water drop by drop through a membrane. A storage tank accumulates the filtered water over time to ensure an adequate water supply when needed. This allows users to have immediate access to a sufficient quantity of water for various purposes, such as filling glasses or pitchers.

  1. Pressure Regulation:

The tank plays a crucial role in regulating the pressure within the reverse osmosis system. When the tank is complete, a pressure-sensing valve detects the increased pressure and signals the system to shut off. This mechanism prevents excessive pressure buildup and maintains the balance between the tank and the filtration system.

  1. Air Chamber and Compressed Air:

The reverse osmosis storage tank contains an air chamber or bladder separated from the water side by a diaphragm. As water enters the tank, it compresses the air chamber. Air, being compressible, allows pressure generation within the tank. This compressed air exerts pressure on the water, pushing it out of the tank and facilitating its flow to the faucet.

  1. Delivery System:

With its air chamber and compressed air, the tank acts as a delivery system for reverse osmosis-filtered water. By utilizing the pressure created by the compressed air, the tank ensures a steady and consistent flow of water from the faucet without needing an electric pump.

  1. Storage Capacity:

Reverse osmosis tanks come in various sizes and shapes, representing their capacity for holding water. The tank’s size indicates its total void volume, but the quantity of water it can have may be small due to the presence of the diaphragm and the required air chamber. The capacity of the tank depends on factors such as feed pressure, RO shutoff, and pre-charge pressure.

Benefits of Reverse Osmosis System:

  1. Reduction of contaminants:

The Reverse Osmosis System effectively reduces contaminants such as pesticides, chlorine, arsenic, sodium, and lead from the water. This ensures that you and your family consume water with significantly fewer impurities.

  1. Improved taste and purity:

By removing contaminants, the system enhances the water’s taste, odor, and quality. In addition, it provides a refreshing and cleaner drinking experience, making water more enjoyable.

  1. Lead removal:

A reverse osmosis filter system can remove lead from your drinking water. Lead is a highly toxic substance that can cause severe health issues such as nerve damage, anemia, brain tissue damage, high blood pressure, heart disease, kidney disease, and infertility, and it is particularly harmful to children.

  1. Convenient access:

The Reverse Osmosis System is conveniently installed at your sink, allowing easy access to purified water whenever needed. You no longer have to rely on constantly refilling pitcher filters or purchasing bottled water.

  1. NSF-certified and performance-tested:

The system is certified to meet NSF (National Sanitation Foundation) standards, ensuring its reliability and effectiveness. In addition, it has undergone rigorous performance testing to provide water that meets high-quality standards.

  1. Professional installation:

The Reverse Osmosis System is professionally installed by licensed plumbers, ensuring proper setup and functionality. This guarantees that the system operates efficiently and delivers the expected results.

  1. Hassle-free maintenance:

The system has a quick change filter that is conveniently replaced. In addition, the replacement filter can be couriered straight to your door, making maintenance simple and hassle-free.

  1. Personalized water purification solutions:

You can receive customized advice based on your water quality and specific needs by booking an in-home consultation with a Water Purification Advisor. The advisor will test your water, discuss your requirements, and recommend the best water purification solution for you and your home.

Problems with Reverse Osmosis Water Filters:

  • Inadequate removal of contaminants: Many reverse osmosis systems may not effectively remove all the pollutants they claim to eliminate. The term “reverse osmosis” has been used broadly, leading to confusion and a lack of standardized filtration capabilities. It is essential to verify that the system you are considering is specifically tested and certified to remove the contaminants in your water.
  • Neglecting prefilter maintenance: Prefilters in reverse osmosis systems play a crucial role in protecting the RO membrane from substances like chlorine that can damage it. Failing to change the prefilters on time can result in chlorine breakthroughs, leading to membrane damage and compromised filtration performance. Unfortunately, this can go unnoticed, and users may unknowingly consume water with high contaminants.
  • Complex installation requirements: Installing a reverse osmosis system often involves drilling holes in the kitchen and may require an expensive plumbing job. Many assume they can handle the installation themselves but later discover the need for professional assistance. Drilling holes in the drain pipe and countertop/sink, along with potential risks of damage, can add to the installation’s complexity and cost.
  • Reduced under-sink storage space: Reverse osmosis systems typically have a storage tank more significant than a basketball. This and the manifold and other components can significantly reduce the available storage space under the sink. As a result, it becomes challenging to accommodate the system and retain its storage capacity, especially for those with garbage disposals or limited under-sink space.
  • Slower flow rates: A common complaint with reverse osmosis systems is slower water flow rates at the tap. This can lead to frustration and impatience, causing some individuals to choose unfiltered water instead. In addition, the reduced flow rates may undermine the convenience and purpose of having a filtration system, as users may opt for quicker access to unfiltered water.

Overall, a Reverse Osmosis System offers the benefits of cleaner, purer, and better-tasting water, with the convenience of easy access and professional installation. It ensures you enjoy worry-free, high-quality water for drinking, cooking, and washing your food.
