1. High-efficiency gas dissolution device dosing system: energy-saving solution for large-scale treatment
Technology core
The high-efficiency gas dissolution device is based on a special venturi water projector, and selectively matches the optomagnetic coupling auxiliary module according to the water quality to further improve the mixing efficiency. Specialized water jets have a unique hose structure compared to conventional jets. At the same time, the unique mechanical structure of the throat part can also ensure that the gas effectively cuts the jet water column and forms micro-nano bubbles, and finally these micro-nano bubbles enter the advanced catalytic oxidation tank, increasing the utilization rate of ozone.
Compared with the conventional aeration plate dosing method, it can increase the ozone utilization rate by 10~20% and effectively reduce the dosage of ozone. And the dosing device is installed outside the pool, which is easy to maintain and has no risk of blockage, which greatly reduces the later maintenance work.
Core strengths
• Low liquid-gas ratio, 1.5~2.5:1 can meet the requirements of use;
• Low head, conventional design power pump 24m head can meet the needs of use;
• High mass transfer efficiency, up to more than 95%;
• Combinational diversity, according to water quality, combined with photocatalytic coupling, can improve ozone mass transfer efficiency, greatly reduce suspended solids and COD content;
• Low operating cost, small liquid-to-gas ratio, and low power of the corresponding power pump;
• High safety, with our ozone preparation system comprehensively considering safety interlocking, front and rear control linkage;
Scenario adaptation: Municipal sewage upgrading and transformation, printing and dyeing wastewater decolorization, papermaking wastewater treatment, photovoltaic wastewater treatment and other difficult industrial wastewater treatment fields.
2. Aeration plate feeding system: stable and durable basic purification scheme
The most common way to add aeration discs in the water treatment process is as follows:
u Plate type microporous aeration disc: diameter 150, interface R1/2", material 316L+titanium, pore 30~50μm;
u Integrated arch silicon carbide microporous aeration disc: diameter 150, interface Rp3/4", made of corundum sand sintered at high temperature, tooth interface is made of ceramic material. The pores are 80~200μ, and the double-sided aeration is not easy to block;
Core strengths
• Low operating cost, no need for additional power drive, high aeration efficiency;
• The air distribution in the pool is uniform, and the bubbles are evenly dispersed, which can be adapted to different shapes of the pool structure scene.
缺点
• In the case of poor water quality or long-term non-aeration, it is easy to block and the maintenance workload is large;
