What is Reverse Osmosis?

Whole house reverse osmosis water system uses the membrane filtration principle of reverse osmosis. Under the push of pressure, water containing impurities will be forced to permeate through the semi-permeable membrane.

However, the pore size of the reverse osmosis membrane is very small and can intercept substances larger than 0.0001 microns. Therefore, it will intercept lead, arsenic, uranium, total dissolved solids, and other harmful substances in the water, while allowing water molecules to pass through to achieve water purification. Its high desalination rate makes it often used for desalination of brackish water and seawater.

How Does a Whole House Reverse Osmosis System Work?

The residential reverse osmosis system will provide purified water suitable for the different water needs of the entire house, such as drinking, cooking, kitchen, shower, etc., based on the water treatment needs of the residents and combined with the working principle of the reverse osmosis system mentioned above.

Whole-house RO systems usually have a built-in pre-filter, which protects the RO membrane in the reverse osmosis water purifier from sediment, suspended solids, colloids, rust, etc. in the incoming water. In addition, the system can also be supplemented with central water softeners, pipeline hot drink machines UV sterilizers, etc., depending on the customer’s water quality requirements and budget.

Which Sources of Water Can Be Treated Using Whole House RO Systems?

Tap water, seawater, river water, well water, and brackish water are the main sources of water in most households. Water drawn from these sources often consists of varying pollutants. The contamination can be naturally caused or result from human activities. This contamination degrades the water quality thereby disqualifying its use in most domestic applications. To remedy water contamination and undersupply, most households are now installing whole house RO systems.

Households drawing their potable water from well water can deploy whole house RO systems to filter out minerals, dissolved salts, heavy metals, and other undesirable elements. For well water treatment, we manufacture and supply reverse osmosis systems for well water. Households in coastal areas have a limited supply of freshwater. With RO watermakers, they can convert seawater into potable water efficiently and economically.

For homes reliant on brackish water, we manufacture top-notch brackish water RO systems. We generally manufacture reverse osmosis systems customized to treat virtually all types of feed water. When placing your order, provide us with information regarding the composition and characterization of your feed water. We will consequently customize the whole house reverse osmosis system to accurately meet your operational specifications.

Will a Reverse Osmosis System Filter Everything in the Water?

The reverse osmosis system has a desalination rate of more than 98% and a high water reuse rate. It can intercept solutes with a particle size of several nanometers or more, and the water produced is close to pure water. However, the reverse osmosis process cannot remove dissolved gases such as hydrogen sulfide and some pesticides, solvents, and volatile organic chemicals (VOCs). Therefore, the RO system cannot remove all substances in the water.

Substances that reverse osmosis systems can remove include:

  • Bacteria
  • Virus
  • Colloid
  • Rust
  • Suspended solids such as sediment
  • Heavy metal
  • Organic matter
  • Parasite
  • Soluble salts 
  • etc.

Therefore, RO water does not contain substances harmful to the human body and can ensure healthy drinking water for your family. At the same time, the RO filter is simple to operate, has a high degree of automation, and has stable water quality. The wastewater produced during the water production process can be used to flush toilets, mop floors, etc.

Are There Different Types of Whole House Reverse Osmosis Systems?

Yes. Different households draw their feed water from different sources. As such, different types of whole house reverse osmosis systems are needed to adequately treat the varying types of feed water. Below, we briefly discuss the distinct types of whole house well water reverse osmosis systems utilized in homes.

●       Well water reverse osmosis systems.

Well water reverse osmosis systems are filtration systems specifically made for groundwater treatment. They get rid of impurities such as dissolved minerals, viruses, bacteria, organic compounds, and metals. Whole house well water RO systems are primarily installed at points of entry. They are manufactured in distinct designs including skid mounts and modular designs.

Figure 4 Skid-mounted whole house reverse osmosis system.

●       Reverse osmosis drinking water systems.

Reverse osmosis drinking water systems are primarily designed to generate safe, uncontaminated drinking water. These systems can literally convert any form of feed water into drinking water. They extract harmful pollutants such as microbial pathogens, dissolved salts, and organic compounds.

●       Whole house RO systems for seawater.

Coastal households are not endowed with freshwater reservoirs like other inland regions. Therein, they are often forced to draw their product water from the surrounding seawater. This is mainly enabled by seawater reverse osmosis systems. Most household RO systems for seawater have TDS levels of 1,500-42,000ppm. They extract up to 99.7% of dissolved salts to generate freshwater with maximum TDS levels of <1000 ppm.

Which Pretreatment Systems Are Used with Whole House Reverse Osmosis Systems?

Certain elements found in feed water are capable of blocking the RO membranes and/or fouling essential components of the whole house RO system. This can result in premature termination of the system’s lifespan or unnecessary repairs and replacements which add to the operating costs. This can however be averted by installing an elaborate pretreatment system next to the whole house reverse osmosis system. Here are some of the most effective water pretreatment systems.

●       Chemical dosing systems.

Chemical dosing systems remove aggressive pollutants using chemical reagents like chlorine and antiscalants. Chlorination is one of the most effective chemical dosing processes that use chlorine to kill microbial pathogens. Antiscalant injection is mainly used to nullify scaling minerals e.g. hardness-causing minerals (calcium and magnesium).

●       Sediment filters.

Sediment filters are filtration systems used to filter out colloidal particles and other floating solids. They are probably one of the most utilized water pretreatment filters. Their deployment mitigates the possible clogging of RO membranes.

●       Carbon filters.

Feedwater with high chlorine concentrations as well as high organic chemical content often necessitates carbon pre-filtration. Carbon filters are ordinarily made of block carbon or granular carbon and they extract chemical pollutants through adsorption. Moreover, they eliminate organic chemicals thereby doing away with bad odors and tastes.

●       Water softeners.

Water softeners are treatment devices specifically designed to eradicate hardness-causing minerals. The most utilized and impactful water softeners are ion exchange softeners. These systems simply get rid of hardness ions (Ca2+ and Mg2+) by swapping them for sodium (Na+) or potassium (K+) ions.

What is the Average Capacity of Whole House Reverse Osmosis Systems?

When procuring a whole house reverse osmosis system, it is imperative that you go for the perfect production capacity. The production capacity of reverse osmosis systems is generally measured in Gallons Per Day (GPD). Most whole house RO systems are manufactured in a range of production capacities. This ensures that all households are well catered for irrespective of their usage demands.

Figure 1 Whole house reverse osmosis system.

Your water usage patterns should essentially guide you in selecting the ideal sizing and production capacity. For instance, if your household uses 200 gallons of water per day, you should opt for a whole house reverse osmosis water system with a production capacity of 300 or 400 GPD. This is because your water demand may surge upwards in the future. A bigger capacity also minimizes the chances of interruption since you have a continuous water supply.

Water usage in households is not as high as water usage in industries and commercial enterprises. Therein, low-volume RO systems are necessitated in homes. Our standard whole house RO systems are manufactured in production capacities ranging from 2GPM to 1,500 GPD.  We however manufacture customized systems with tailor-made sizes, flow rates, and production capacities.

Back to the guide ⇪

How To Size a Whole-house Reverse Osmosis System?

 Factors to consider when choosing a whole-house reverse osmosis system include the number of permanent residents, the water quality in the area, your family’s water needs, the space under the sink, and the total height of your floor/floor.

Water treatment products require different spaces due to different functions, different installation locations, and different product model sizes.

After determining the water treatment needs and the type of equipment that needs to be installed, you can plan the installation space and reserve water, electricity, drainage, and other processes.

How Durable is a Whole House Reverse Osmosis System?

NEWater’s whole house reverse osmosis systems are intelligently designed to guarantee the quality, first-rate performance, and durability. Where other systems average a lifespan of 15 years, our systems average a lifespan of 20 years. This is made possible by the high-quality materials we use as well as the ingrained ultra-modern technologies.

However, for a whole house reverse osmosis system to last 20 years, adequate pretreatment and maintenance are needed. Certain components such as the reverse osmosis membranes and the pretreatment filters also necessitate periodic replacements. For example, a high-quality membrane utilized appropriately can optimally function for 3 years.

After three years, the membrane should be replaced to avoid the passage of objectionable impurities. Users are also advised to ensure that the feed water meets the stipulated specifications and that the operating conditions e.g. temperature and pressure are also conducive. Grab long-lasting and highly whole house reverse osmosis systems at an affordable rate by ordering from NEWater.
