A bioremediation device and process for remediation of waste collection systems. The present invention preferably comprises an bioactive element having an outer and an inner portion. The concentration of the bioactive element in the outer portion differs from that of the inner portion so that the concentration is greatest when the waste material is first exposed to the outside of the element and diminishes while the solid dissolves in the waste material. The outer portion is disposed about the inner portion such that substantially all of the outer portion is dissolved for delivery of the bioactive element into the waste material before dissolution of the inner portion occurs. The outer portion has a relatively great bioactive effect for remediating the waste material and the inner portion has a relatively lesser bioremediating effect for maintaining the waste material in the collection systems.
