Pure water is essential for various applications, from common drinking water at residences and offices to various industrial applications. There are several water purification technologies; reverse osmosis is one of them.
This technology is used to efficiently remove a majority of contaminants from water. The way it purifies water is by pushing water under pressure through a semipermeable membrane.
Osmosis is the natural process of the migration of a weaker saline solution to a strong saline solution. Reverse osmosis as the name suggests is the same process in reverse. A semipermeable membrane allows the passage of water molecules but the majority of dissolved sales and bacteria.
Some of the other applications of an RO system include that in desalinating facilities to remove salt for ocean water, recycling water contaminated by chemicals, purification of water with high fluoride levels, at power stations to remove minerals from boiling water as well in various commercial industries.
A well designed reverse osmosis system will provide high-quality drinking water for a long time. However, the key to ensuring it lasts long is to maintain it well. This article provides more information on reverse osmosis system maintenance to ensure it runs efficiently and is long-lasting.
Importance of reverse osmosis maintenance
Water purification systems are implemented in residential, commercial and industrial places to ensure pure drinking water for various purposes.
The unit must be working efficiently to ensure it removes the contaminants like heavy metals, pesticides, viruses, bacteria as well as the taste and odour associated with it. The presence of calcium and magnesium will make the water hard.
An RO system has to work quite hard to ensure the purification process is completed efficiently each time. The harmful elements cause wear and tear over time making it essential one maintains it regularly.
With regular reverse osmosis filter maintenance, you can be sure it is always working at maximum efficiency.
Tips to maintain your reverse osmosis system
Several industries make use of large water purification systems; however, the level of water purification might differ depending on the type of industry. For example, the food & beverage, pharmaceutical, electronic industries require a different level of water purification.
The main components of an RO system include a storage tank, check valve, automatic shutoff valve, cold water line valve, drain line, flow restrictor, pre-filter, post-filter, carbon filter, RO faucet, RO membrane, etc. Each component plays a role in ensuring pure water.
Here are several tips to help maintain it to ensure it remains efficient:
- The filter element of a security filter must be replaced periodically to guarantee good water quality.
- Monitor the water quality on a routine basis to know when to replace the filter element.
- It is important to avoid sun exposure for the tank and for those who do not know how to clean the reverse osmosis tank; hire professionals to do it.
- Drain the RO storage tank regularly to maintain the high quality of the water.
- Record the operation parameters of your industrial RO system at regular intervals.
- Inspect the raw water pump and high-pressure pump on a routine basis and also replace the lubricating oil as per the system requirements.
- Some of the other systems that require routine inspection include the conductivity gauge, PLC systems, pressure gauge, etc.
- It is essential to change the RO membrane every 3-4 months. Water is pushed through the membrane and is responsible for separating the solutes from the solvents. Only the pure solvents are allowed to pass through. This is an integral part of your RO system hence it is essential to clean it regularly to avoid clogging of the pores.
- Contaminants from the RO purifier will clog the filter hence this also needs replacing periodically.
- Some of the common maintenance tasks include water filter maintenance, sanitizing tanks, replacing RO membrane, cleansing and re-assembling the plumbing pipes. It is also essential to check the pressure nozzles at regular intervals as well as replace other parts as necessary.
- Forgetting to change the filter can result in a decrease in water production.
- Make use of a softener to soften the water; this will not hurt the RO system.
- The final filter of an RO system is usually the GAC filter (Granular activated carbon). This is responsible for removing the taste and odour in the water. This must be replaced on a routine basis as well.
- It might be advisable to seek help from professionals for the replacement of filters and routine inspection. They will also have the ability to spot if there is a problem with drip or leakage.
- This system might seem simple enough, however; it is not a good idea to attempt maintenance without any technical knowledge of the system.
- If attempting maintenance work on the RO system yourself ensures the replacement filters are from a sealed original packing. Avoid doing it in dusty or dirty places and make use of gloves while doing so.
- Always shut off the system before attempting DIY maintenance. The frequency of changing different filters will vary. The type of filters to be replaced also depends on the size of the RO system installed.
- Some of the common fillers include sediment, carbon, reverse osmosis and polishing filter. For those wondering how often do you change filters on reverse osmosis? The frequency to replace these filters ranges from 6 to 24 months.
Where to buy a reverse osmosis system?
Several companies offer water and wastewater treatment. They also supply a wide range of equipment for this purpose. It is a good practice to spend some time on the Internet researching the type of products you might require for your industry and which companions offer such products and services.
Some of the popular products offered by companies include reverse osmosis units of various sizes, ultraviolet sterilization systems, chlorine disinfection units, water softener units, cartridge and bag filtration units, portable disinfections skids and media filtration systems.
