Removing ammonia from household wastewater

How to control the ammonia from waste water that is coming from household water? I am controlling by irrigation method. But by using this method some ammonia decrease. Our requirement is that maximum ammonia be removed from water. Inlet water has 67 mg/l ammonia come, but by using irrigation method ammonia remains 40 mg/l. Please tell me how to control this?
I shall be very thankful to you for this.
