Reverse osmosis, also referred to as RO, is a water filtration process used in many industrial effluent treatment plants to effectively clean wastewater produced during manufacturing. Although there are other methods of cleaning wastewater, reverse osmosis is becoming a popular solution to the problem of contaminated effluent, thanks to its effectiveness, affordability, and eco-friendly nature. The process is really very simple. An effluent treatment plant that operates this kind of system uses a high-pressure pump to force the wastewater across a semi-permeable membrane. It’s important that the membrane be semi-permeable as this is what allows the contaminants to be filtered out. The high pressure forces the water through the membrane, and particles such as heavy metals, chemicals, bacteria and more, are captured. Although more and more industries are using RO in the setting of an industrial effluent treatment plant, there are still many myths about the method. Here’s the truth about some common misunderstandings. RO filters are expensive to maintain: Myth Many people assume that the filters don’t last that long, and that simply isn’t the case. The lifespan of a filter depends on a number of factors, such as the conditions of the industrial effluent treatment plant, the water quality, and how well the system is maintained. In fact, with regular cleaning and professional maintenance, filters can have a relatively long life. The average industrial consumer can expect to save with an effective and regularly-maintained RO system. The water has fewer healthy minerals: Myth A common myth is that RO water is demineralised and is therefore not as healthy as other solutions when re-used. This is false. The special membranes used in the filtration process only remove certain minerals and, while what’s produced does have a lower percentage of minerals, some do remain. It is wasteful: Myth While early systems may have been more wasteful in the past, thanks to technological innovations, modern RO systems are very water and energy efficient. There are a number of techniques used to reduce the amount of water wasted, such as using energy recovery devices and optimising systems as much as possible. Compared to other methods used in industrial effluent treatment plants, RO is a more eco-friendly option. The system is complicated: Myth It’s true that filtering systems can be complex, however, improved design and automation means that this technology is pretty easy to use – when installed and maintained correctly, by experts. Today’s reverse osmosis plants employ user-friendly interfaces and many steps can be automated to make the whole process as simple as possible within a variety of industries. If you’re considering switching to or installing an industrial effluent treatment plant that uses reverse osmosis as its base technology, then be sure to work with an experienced and reputable company. Their experts will have the knowledge to ensure that you reap all the benefits of this effective water treatment system. Plus, if you have any questions about what’s fact or fiction, they’ll have all the answers.
