In industrial production, the spraying process usually requires a large amount of water. FOXSEN realizes the recycling of spray water. The used water can be reused in the spraying process after treatment. It can also be used to irrigate flowers and plants. This greatly reduces the demand for fresh water resources. At the same time, reducing wastewater discharge can protect natural ecological environments such as soil, rivers and lakes, maintain ecological balance, ensure the living environment of aquatic organisms, and reduce the loss of biodiversity caused by water pollution.
