RO filtration is commonly installed in homes and businesses to purify drinking water. It is also used in industrial and commercial applications such as seawater desalination, ultra-pure water for electronics manufacturing, and wastewater treatment. A RO water filtration system is one option for a house water filter.  Using pressure, reverse osmosis removes contaminants from water by forcing water molecules through a semipermeable membrane. The contaminants are filtered out and flushed away during this process. You may be interested to know that reverse osmosis technology is not revolutionary. In fact, municipalities began using RO processes in 1977. Since then, reverse osmosis has become increasingly popular because it is safe, cost-effective, and easy to maintain.





A reverse osmosis filter forces water molecules through a semipermeable membrane. The membrane allows only water molecules to pass through and filters out contaminants such as bacteria, viruses, heavy metals, and chemicals. A post-filter polishes the drinking water after it exits the RO membrane before entering a dedicated faucet. Prefilters and post-filters determine reverse osmosis systems stages.  The contaminants are then removed from the water and flushed away. Purified water is then collected for use. A reverse osmosis filter can generate 10 to 75 gallons (45-340 Liters) of water per day.


What is the purpose of an RO storage tank?

When you need reverse osmosis water, you have plenty in an RO storage tank. Reverse osmosis slows down the process of making water. – Two to three ounces of RO water can be produced in one minute. For a glass of water, you would have to wait at least 5 minutes if you turned on your faucet at the actual membrane production rate. Your glass fills instantly when you use a storage tank. – Storage tanks also improve the efficiency of RO systems. Having stored purified water allows the system to operate more efficiently since it does not need to constantly filter water. Large families or households with multiple appliances that require purified water may find this especially useful. – By reducing the frequency of the system’s cycles, a storage tank can also prolong the life of the RO system. The lifespan of the components of the system can be extended by reducing the number of times the system needs to filter water.



Water and wastewater purification:

Water shortages in Los Angeles and other cities are solved by reclaiming rainwater from storm drains and using it for irrigation and cooling. A reverse osmosis system removes minerals from boiler water at power plants. In order to prevent corrosion, it must be as pure as possible. A boiler with deposits inside or outside the tubes may underperform, reducing its efficiency and resulting in poor steam production, and thus poor turbine power. Effluent and brackish groundwater can also be cleaned. A reverse osmosis system should be used for effluent treatment in larger volumes (over 500 m3/day). A reverse osmosis system’s membrane life is extended, which reduces treatment costs. Deionized water can be produced using reverse osmosis. Water purification by reverse osmosis does not require thermal energy. Reverse osmosis systems can be regulated by high-pressure pumps. Purified water recovery depends upon various factors, including membrane size, membrane pore size, temperature, operating pressure, and membrane surface area. In 2002, Singapore announced that a process named NEWater would be a significant part of its future water plans. It involves using reverse osmosis to treat domestic wastewater before discharging the NEWater back into the reservoirs.


In reverse osmosis filters, wastewater is created as follows

Reverse osmosis filters generate wastewater, called brine or rejected water, as part of the filtration process. This wastewater is created when the semipermeable membrane filters out contaminants and only allows clean water molecules to pass through. Contaminants are flushed away, while clean water molecules are collected for use. Wastewater is usually disposed of through the sewer system. For every gallon of clean water produced, a typical point-of-use RO system generates five gallons or more of wastewater. However, there are several ways to reduce or avoid wasting water:

  • A high-efficiency RO system produces more purified water using less water than others. For each gallon of wastewater generated, look for systems with a high recovery rate.
  • Reduce the amount of wastewater generated by an RO system by using a permeate pump. By increasing the pressure on the RO membrane, more pure water is produced per gallon of wastewater.
  • Some RO systems can be designed to recycle wastewater, using it to water plants or flush toilets. Water waste can be reduced this way.
  • Using a water-saving faucet when accessing purified water from the RO system can reduce water usage. To save water, choose faucets with low flow rates or install a flow restrictor.
  • Make sure the RO system is properly maintained to reduce wastewater generation and improve its efficiency. Check for leaks, damaged, and leaky filters, and replace them as necessary. By implementing these measures, it is possible to reduce or avoid wasting water when using a reverse osmosis system.

Polypropylene microfibers are melt-blown into this Sediment Filter. A high-capacity filter removes rust, silt, scale, sediment, dirt, coarse sand, and sand from water. Due to its high dirt-holding capacity, it lasts longer. This protects the membrane from clogging and damage.


Stage 2: CTO Block activated carbon filter

High-quality carbon is used in the construction of the Carbon Block CTO. Chemical absorption is high due to the structural design. This process removes chlorine, volatile organic compounds (VOCs), and pesticide residues that can affect the taste and odor of water.


Stage 3: RO Reverse osmosis filter

Water filtered with 0.0001um precision is pure and healthy. Among other things, it removes bacteria, heavy metals, salts, chemical pollutants, and other dissolved matter. When water is forced through a semipermeable membrane, 99% of health-related contaminants are removed


Stage 4: T33 Post-activated carbon filter

In-line filtering with high-quality carbon removes all residual impurities and odors from the tank and stabilizes water taste quality. Post-filtering removes any remaining contaminants and improves the water’s taste and quality. **Optional cartridges:


Stage 5: AAF Alkaline antioxidant filter

By passing the water through the alkaline and hydrogen filters, the pH value will increase and hydrogen ions will be boosted. This will improve the body’s acid/base balance. The remineralization stage improves the taste and nutritional value of the water by adding beneficial minerals like calcium and magnesium.


Factors that influence RO system cost:

  • Type of system – Pretreatment
  • Installation cost
  • Maintenance cost
  • Additional components



Home reverse osmosis water treatment benefits.

  • Your water will be free of dissolved solids, chlorine, fluoride, microorganisms, and heavy metals such as barium, cadmium, chromium, lead, and mercury. Drink, cook, and freeze RO purified water for better taste than bottled water.
  • It dispenses filtered water directly to your sink making it convenient for drinking, cooking, making ice, watering plants, and making beverages. The system requires minimal maintenance, typically replacing filters periodically.
  • RO systems are cost-effective over time compared to purchasing bottled water or using other filtration methods. RO systems provide clean water for the household at a fraction of the cost of bottled water.
  • When the tank is full, the feed line is automatically shut off to eliminate waste.
  • Help the environment & save money! Each year, consumers waste 3 billion pounds of plastic on bottled water. By using a reverse osmosis system at home, you can avoid buying expensive bottled water and reduce your carbon footprint.
  • RO systems also use less energy and resources than other water treatment methods. Drinking clean and purified water can provide several health benefits, such as improving digestion, boosting the immune system, and promoting healthy skin and hair.


Benefits of alkaline mineralization

  • Restores calcium and magnesium minerals (ions) removed during reverse osmosis to create pH-balanced, alkaline mineral water on tap.
  • Enhanced flavor for great-tasting water, coffee, and beverages.
  • Because alkaline water has a smaller molecular structure, it penetrates cells more easily than regular water. Energy and hydration can be improved.
  • It may have antioxidant properties, meaning it can neutralize harmful free radicals in the body that cause cellular damage and contribute to chronic diseases like cancer, diabetes, and heart disease.
  • Alkaline water can help neutralize stomach acid, which can improve digestion and reduce acid reflux symptoms.
  • Calcium and magnesium, essential minerals for strong and healthy bones, are found in alkaline water. Prevent osteoporosis by drinking alkaline water.
  • By reducing acidity and improving cellular function, alkaline water may enhance the body’s natural detoxification process.



How Much Of A Contaminant Can A Reverse Osmosis System Remove?

  • Fluoride (85-92%)
  • Lead (95-98%)
  • Chlorine (98%)
  • Pesticides (up to 99%)
  • Nitrates (60-75%)
  • Sulfate (96-98%)
  • Calcium (94-98%)
  • Phosphate (96-98%)
  • Arsenic (92-96%)
  • Nickel (96-98%)
  • Mercury (95-98%)
  • Sodium (85-94%)
  • Barium (95-98%)

Generally, RO replacement filters should be installed based on the following schedule:

  • Pre-filters (sediment and carbon filters): Replace every 6-12 months
  • Reverse Osmosis Membrane:** Replace every 24 months
  • Post filter (GAC polishing filter): Replace every 12 months

Some factors that may affect Reverse Osmosis System performance:

  • Incoming water pressure (most municipal and city tap water has 40-85 psi, but if water pressure is too low, the RO system will not operate properly)
  • Water temperature (i.e. cold water takes longer to filter)Warmer water can improve the efficiency of the RO membrane, allowing more purified water to be produced.
  • Type and number of total dissolved solids (TDS) in tap water
  • The quality of the filters and membranes used in the RO system (see operating specifications for your system).
  • RO system operation is dependent on feed water pressure. Low pressure may prevent the system from producing enough purified water. In contrast, too high pressure can damage the system and reduce its lifespan.
  • A good RO membrane is critical to the performance of the system. High-quality membranes can produce more purified water and last longer.
  • RO membranes can be pre-treated with filtration, softening, and chemical treatment to remove particles and contaminants.
  • Keep the RO system running smoothly with regular maintenance. Replace filters, check for leaks, and clean the system as needed.



Maintaining a reverse osmosis drinking water system:

To prolong the lifespan of a reverse osmosis (RO) system, regular maintenance is essential. RO system maintenance tips:

  1. Pre- and post-filters on RO systems need to be replaced periodically. Replacement frequency depends on the quality of feed water and usage. Typically, pre-filters need to be replaced every 6-12 months, while membranes have to be changed every 12 months.
  2. Clean the RO membrane: Over time, the RO membrane can become fouled with contaminants and minerals, reducing performance. It is important to clean the membrane periodically.
  3. Check for leaks: Regularly check for leaks in the system, including at the connections and in the storage tank.
  4. Clean the storage tank: The storage tank should be maintained periodically to prevent bacteria and mold growth. Drain the tank completely and use a mild detergent to clean it. Rinse thoroughly before refilling.
  5. Monitor water quality: Check the quality of the purified water periodically to ensure the system works properly. If you notice a drop in quality, it may be time to replace the filters or clean the membrane.
  6. Check the water pressure: Ensure that the water pressure is within the recommended range for the RO system. Low pressure can reduce the system’s performance, while high pressure can damage the membrane. By following these maintenance tips, you can ensure that your RO drinking water system operates at peak performance and delivers high-quality purified water.



The RO permeate can be further improved by post-treatments such as coral calcium mineral cartridge after the RO system, enabling it to be used in conjunction with the creation of healthy drinking water, or especially for a water ionizer, which must have minerals in the water to create the alkaline mineral drinking water. It is crucial to pretreat and monitor RO systems correctly to prevent unscheduled maintenance and costly repairs. You can expect many years of high-purity water from your RO system if you use the correct system design, and maintenance program, and follow the manufacturer’s instructions in their owner’s manual. We manufacture multiple types of systems that purify your family’s drinking water and generate healthy alkaline mineral water.
