Common diaphragm electrolyzer were revamping by activated cathode process and modifieddiaphragm process. Voltage was reduced, and effect on saving electricity was obvious.
采用活性阴极改性隔膜技术对普通隔膜电槽进行改制，降低了槽电压、节电效果显著。

To improve the cavitation performance of diaphragm metering pump, a comparison of cavitation test is made between the modifieddiaphragm metering pump and the original measuring pump.
