Wastewater treatment is an important process for removing pollutants contained in domestic and industrial wastewater to make it safe. Various methods and facilities are used for wastewater treatment, depending on the type of wastewater and the pollutants it contains. Fundamentally, these methods can be divided into three categories: "physical treatment," "chemical treatment," and "biological treatment." Each method has a variety of techniques and processes, and by appropriately combining these, efficient water quality purification can be achieved. This article will clearly explain practical knowledge from the basic concepts of wastewater treatment to the main treatment methods such as physical treatment, chemical treatment, and biological treatment, as well as methods for removing harmful substances. *For more detailed content of the blog, please refer to the related links.

• Water Treatment

In wastewater treatment, "coagulation and sedimentation" plays an important role. In the coagulation and sedimentation method, fine substances in wastewater, such as heavy metals, are bound together with a coagulant to form large clumps called "flocs," which are then separated from the water by settling or floating. Understanding the principles of coagulation and sedimentation and the process by which flocs settle is a key point that beginners in wastewater treatment should grasp. This article will provide a detailed and easy-to-understand explanation of the basics of coagulation and sedimentation as well as specific treatment methods for beginners. *For more detailed information, please refer to the related links.

• Water Treatment

Water is an essential element for human survival. It is needed not only in daily life but also in various situations such as agriculture and industry. Since water is not infinite, it is necessary to purify contaminated water and return it to nature. The process of removing impurities from water for human use or to return it to nature is called water treatment. We will introduce what water treatment is, the types of water treatment, and information about Suirei's water treatment. *For more detailed content, please refer to the related links.

Our company proposes a "recycled water treatment system" that returns purified water back to the production line instead of discharging wastewater, allowing for a continuous circulation within the factory. This system can recycle factory wastewater at a rate of 70% for the "semi-closed type" and nearly 100% for the "fully closed type," enabling our customers to fulfill their social responsibilities. Not only does it support our customers' "legal responsibilities," but it also aims to achieve the "social responsibilities" of the local community, government, and industry, serving as a partner that connects with nature and fosters "affinity" for the future. 【Recycling Rate】 ■ Semi-closed type: 70% ■ Fully closed type: Nearly 100% *For more details, please refer to the related links or feel free to contact us.
