Many people often struggle with wastewater problems when buying water purifiers, and even give up buying water purifiers. In fact, you don't have to worry too much, compared to the water we use in bathing and flushing toilets every day, the wastewater discharged by the water purifier is actually very small.
In addition, the purified water quality of the water purifier with wastewater discharge is safer and more secure, and at the same time, it can also extend the service life of the filter element and save the cost of water purification.
In order to purify water more efficiently, the reverse osmosis water purifier has a special waste pipe when it is working to discharge the trapped harmful substances. The main component of wastewater is harmful impurities such as bacteria, viruses, organic matter, and heavy metal ions intercepted by RO reverse osmosis membranes.
The generation of wastewater first stems from the working principle of reverse osmosis water purifier. The work of a reverse osmosis membrane is essentially the process of concentrating a liquid: when water flows through a RO membrane, clean water flows out from one side of the membrane, and the "concentrated water" containing higher concentrations of organic matter and metal ions on the other side is discharged to form "wastewater".
In addition, the water purifier also generates wastewater when it automatically flushes the filter element. In order to avoid the accumulation of impurities intercepted by the RO membrane and cause the filter element to clog, the water purifier will use automatic backwash technology to clean the RO membrane to ensure the long-term use of the filter element.
Therefore, the reverse osmosis water purifier produces wastewater, not only to ensure that the effluent quality meets the standard of cleanliness and safety, but also to extend the service life of the filter element and provide users with more durable and stable water purification services.
Indeed, there are ultrafiltration machines on the market, which use ultrafiltration membranes as the core component. The pore size of this ultrafiltration membrane is much larger than that of RO membranes, so there is no need to apply additional pressure when filtering out impurities. As a result, the ultrafilter does not need to be plugged in and does not produce wastewater discharge, making it quite convenient to use.
However, it should be pointed out that the filtration accuracy of the ultrafiltration machine is indeed lower than that of the reverse osmosis water purifier. In areas with poor water quality or serious industrial pollution, in order to ensure the purity and safety of drinking water, it is recommended that you choose to use a RO water purifier. After all, pure drinking water is what makes us feel more at ease.
Of course. In fact, the wastewater from the reverse osmosis water purifier is not useless. After the multi-stage filter cartridge filtration in the previous section, most of the impurities have been removed, except for the salt content and bacteria content is slightly higher than that of tap water, other indicators such as turbidity, color, organic matter and large particles of impurities are lower than that of tap water.
Although this water is not drinkable, it has a wide range of uses in daily life. Whether it's watering flowers, flushing the toilet, or mopping floors, it's a great choice. Not only does this save energy, but it also helps us save money.
So, how to collect wastewater from a water purifier? Let me give you some advice.
Method 1: Simple and straightforward, connect the waste pipe directly to the bucket.
You can choose a bucket with a moderate opening, large capacity, and not easy to tip over, and put the waste pipe in it. In this way, the wastewater can flow directly into the bucket. However, it is important to note that there may be a risk of overflow with this method, so it is advisable to place the bucket in a lower position and make sure there are drains around it.
Method 2: Connect the wastewater pipe to a place where a large amount of water is needed.
If you're hands-on, consider DIY a wastewater** system. Alternatively, you can pipe your wastewater to a sink, washing machine, toilet, or other equipment or container that requires a lot of water, so that you can make better use of your wastewater. This will make the most of the wastewater and facilitate your daily life.
No matter which method you choose, the rational use of wastewater from the water purifier is an environmentally friendly and economical practice. Hopefully, these suggestions will be helpful to you.
Now we know that the reverse osmosis water purifier does not actually waste a lot of water, but because of the wastewater discharge, the water quality is safer and more secure, and it can also extend the service life of the filter element and save the cost of water purification. Wastewater can also be reused to save water resources. The questions are solved, and you can rest assured that you can install a water purifier to ensure the safety of family drinking water.
