Method for predicting wastewater treatment performance

A method for predicting a membrane contact process performance of a membrane contact device that removes ammonia contained in wastewater, the method comprising:

• inputting wastewater conditions;
• inputting membrane contact process conditions of the membrane contact device;
• calculating a concentration of vaporized ammonia (NH3(aq)) in a wastewater moving unit within the membrane contact device;
• calculating a diffusion flux (J) of ammonia (NH3(g)) absorbed into an absorption unit through pores of the membrane contact device;
• calculating a removal rate of ammonia from a mass (m) of the absorbed ammonia;
• and
• verifying the calculated ammonia removal rate.

A method for predicting a membrane contact process performance of a membrane contact device that removes ammonia contained in wastewater, the method comprising:

• deriving optimal wastewater conditions and optimal membrane contact process conditions of the membrane contact device so that an ammonia removal rate from the wastewater becomes an optimal value;
• supplying the wastewater to the membrane contact device under the optimal wastewater conditions;
• adjusting the membrane contact process conditions to match the optimal membrane contact process conditions;
• and
• verifying the ammonia removal rate calculated using the optimal wastewater conditions and the optimal membrane contact process conditions.
