Reverse Osmosis Filtration Systems

Water contamination is one of the concerns for everyone drawing water from the well, city water sources, or other water bodies. If you are drawing water from the city water source, you are receiving the water that is sanitized and treated to remove certain contaminants. However, you still need to check out for chemicals like chloramines, fluoride, and chlorine, which may pose severe health hazards. If you are drawing water from a well and drinking it directly there are chances that you are consuming water laden with contaminants from pesticides or chemical factories or waste produced by different sources. There are several water treatment systems that claim to offer a permanent solution from harmful contaminants; however, reverse osmosis systems are the most effective among them. At Cannon Water Technology, we provide reverse osmosis systems from industry-leading brands. Our selection features reverse osmosis filtration systems as well as several reverse osmosis components, which are proven to offer effective results in contaminant removal. We assure the fastest turnaround times on all reverse osmosis equipment listed on this page.

What is Reverse Osmosis Filtration System and How it Improves Water Quality?

Reverse osmosis is a water filtration process where water from a source is made to pass through a semi-permeable membrane. This membrane removes dissolved inorganic solids from the water. This process is quite unlike other water filtration options where water is pushed through only filtration media. Here, water is made to pass through different water filtration media and purified water then goes to the storage tank and contaminants are directed to the drain. Reverse osmosis systems are designed to remove contaminants such as fluoride, lead, pesticides, chlorine and chloramine, nitrates and sulfates, arsenic, volatile organic compounds (VOCs), herbicides, pesticides, detergents, and many more.

Applications of Reverse Osmosis Filtration Systems

We regularly provide RO systems for use across the following industries:

• Boiler feed
• Food and beverage industry
• Environmental
• Marine
• Power and energy
• Pharmaceutical

Components of Reverse Osmosis Filtration Systems

A typical RO system may comprise the following components:

• Water Supply Connector: As the name suggests, this connector connects your RO system to the water supply. It is also known as feedwater supply adapter. The connector must be matched with the right valves and fittings for desired results.  
• Sediment Pre-filter: This is a type of cartridge filter that helps remove grit, sand, minerals, and oxide particles from water. If left unremoved, then the contaminated water may clog the RO membrane or drain flow restrictor. Both these factors hinder water filtration. For effective results, the pre-filters must be changed every 6 months.
• Carbon Filter for Chlorine and Chloramine Removal: Chlorine has been the most popular disinfectant used for water sanitation over years. It helps prevent the growth of algae and harmful microbes that would cause serious illnesses and even death. The effectiveness of chlorine in killing microbes has been substantiated over the years. However, that is not enough. Chlorine residues in water can have a negative impact on RO membrane and above all – human health. Thus, many city water utilities set the chlorine level to 1.0 mg/L. The carbon filter helps remove chlorine from water and protects the membrane from its side effects. Some carbon filters are also designed to remove chloramines from water. There are several studies that substantiate the effects of chloramines on human health. These chloramines are byproducts of chlorine. For effective results, activated carbon must have sufficient contact time with chloramine. Effective chloramine removal is challenging than chlorine removal and requires almost five times more carbon contact time.
• Auto Shut Off Valve: RO storage tanks are fitted with auto shut-off valves, which would help reduce water wastage by stopping the reverse flow of water to drain when the tank is full. When the water storage tank is filled to 2/3 of its feed pressure the valve severs the water supply to the tank and restores it when the tank is drained to 1/3 of the feed pressure.
• Reverse Osmosis Membrane: This is the most effective component of the RO filtration system and removes 99% of total dissolved solids including different types of metals, minerals, salts, organic substances, and microorganisms. This membrane also serves as a barrier between the rejected water and purified water. Purified water is sent to the storage tank and rejected water is directed to the drain. Most RO systems are known to produce around 4 gallons of wastewater against 1 gallon of purified water.
• Check Valve: They help prevent filtered water from the pressurized tank from flowing back to the membrane when the shut-off valve turns the feed pressure to the membrane.
• Pressurized Water Storage Tank: The pressure tank stores the water purified by the membrane and provides filtered water on turning the water faucet. The tank features a water chamber and an air chamber, which is separated by a bladder. This bladder expands when the tank is filled with RO purified water. This expansion compresses air and when the faucet is turned on, this air pushes the water out.
• Drinking Water Faucet: They dispense purified water from a storage tank.
• Water Softener: If are you are familiar with your water chemistry which suggests the presence of several hard minerals, then you must pass the water through a softener before directing it to the RO system. A reliable water softener will help improve the lifespan of your RO membrane. If feed water comprises hard minerals and is directly made to pass through the membrane, its lifespan may reduce and require quick replacement.
• Optional RO Components: You can fit these water filtration systems with optional components such as:
  • Booster Pumps: These pumps provide extra pressure to the RO membrane, and this helps ensure adequate flow from the system.
  • TDS Water Quality Monitors: A TDS meter helps detect the working efficiency of your RO system. It helps analyze the capability of your distillation or RO system in removing harmful dissolved solids from water. TDS meters are an integral part of several service test systems, too.
