A new process for the treatment of fertilizer effluent using immobilized urease

 A method is reported for the treatment of industrial fertilizer effluent rich in urea by a new coupling method to immobilize crude urease onto polyester which is having high flow through property in columns. Kinetics of the immobilized enzyme is established in small column. A typical treatment process with two larger columns in packed bed mode is discussed with and without recycling the treated effluent.
