Rainwater recycling system
Thread Content
Recently, the boss had the idea of reusing the water collected from the factory roof or rainwater drains during rain. I would like to ask if anyone has already implemented any processes for this purpose on site. This post was last edited by johncom on 2009-2-20 at 13:46
Our company is working on a project to separate rainwater from sewage. I can give it to you for reference after it’s done.
What is the purpose of the rainwater collected by the original poster?
The company’s factory area is too small; comprehensive urban utilization would be more effective, but don’t overlook the fact that water is needed everywhere on Earth.
Of course, it should be recycled and returned to the cooling tower; at least that’s my current idea, after all, the water quality control in that case is relatively loose
The key is to see how large the area you can cover for collecting water is; in other words, the coverage area for gathering rainwater. If it’s small, the amount of water collected will be too little； It only becomes valuable when it grows up. Additionally, initial rainwater drainage is also required; it seems there is a dedicated valve system for removing this initial rainwater. As for treatment, a sand filtration system will suffice.
Chemical plants can be built casually over several tens of thousands of square meters; if the roofs for storage areas are also included, the area must be quite large! Yet it all depends on the weather – on how heavy the rain is. My plan involves collecting water from various pipes into a \"rainwater retention tank\", installing an automatic debris barrier to remove branches and trash, and finally setting up an automatic backwash sand filtration system. The purified water is then sent to fire suppression tanks for use in emergencies
