The new high-efficiency shallow air flotation machine is developed by our company based on the latest foreign technology and combined with the actual situation of China's sewage treatment system through nearly ten years of continuous testing, use, and improvement. Compared with traditional air flotation machines, the new high-efficiency shallow air flotation machine changes the static inlet dynamic outlet to dynamic inlet static outlet, allowing suspended solids (SS) to float vertically on the water surface in a relatively static environment. The sewage only takes 2-3 minutes in the purification tank, and the treatment efficiency is extremely high. More than 20 domestic chemical pulp, semi chemical pulp, waste paper papermaking, chemical, leather, urban sewage and other units have used our company's air flotation machine and have all met the discharge standards; And combined with the use of internationally advanced drugs developed by our factory, the cost is greatly reduced, only two-thirds of the original drug cost.
