influent ph
Although the influent pH values were higher than the optimum range of autotrophic denitrification at 8.7~10.1, the effluent pH was stable at 7.2~7.9 due to the production of hydrogen ions during operation.
      
For each temperature selected, the influent pH values were 7.6 (initial pH of the waste used) and 7.0.
      
An increase in pH between influent (pH 6.9) and effluents (pH 7.5) was observed.
      
Lowering the influent pH to 4, the influent Zn2+ concentration to 50mg/l and increasing the flow rate to 800ml/h (residence time: 2.6 min), resulted in decreased sorption capacities by 15.3, 7.7 and 9.6%, respectively.
      
Equalization can help promote the control of influent pH; however, most wastewater streams require a pH control system to maintain this pH range.
      
Influent pH was slightly above neutral and no pH adjustment was made.
      
Low influent pH caused an increase in the effluent hardness while a high influent ionic strength caused the poorest effluent chemical oxygen demand.
      
Second, the effluent pH of 7.2 during the entire column run was essentially equal to the influent pH.
      
The influent pH and ionic strength will control both the effluent quality and removal efficiency.
      
The influent pH and ionic strength will affect the effluent quality and removal efficiency for this filter.
