Abstract:

Assessment and screening of water stabilizer is a key link on industrial and domestic water treament. An dynamic simulated experimental device for circulated water introduced here is a special water stabilizer assessment unit. By getting tendency of dirt resistor, it gives comprehensive assessment for water stabilizer producing effectiveness and technological condition. Working principal of the unit and a method of object-oriented water stabilizer on-line assessment are particularly introduced. The assessment system's hardware and software structure and software functions are included. The practice proves that the developed system possesses friendly interface and reliable performance. It meet the demands of long working period and high performance. Water stabilizer could be assessed directly by dirt resistor varying tendency.

Key words: water treatment, water stabilizer assessment, computer measurement and control
