Abstract

A wastewater treatment system for treating wastewater effluent flowing through a sewer pipe from a sewage treatment plant, and specially designed chlorine tablets for use in the treatment system. In a preferred embodiment the wastewater treatment system is characterized by a wastewater flow conduit which is mounted in the sewer pipe and a tablet loading neck, closed by a removable lid, extends upwardly from the wastewater flow conduit. A tablet support rod extends downwardly through the lid and tablet loading neck into the wastewater flow conduit. Multiple treatment tablets, each having a central opening, are slidably mounted on the tablet support rod in stacked relationship, and as the tablets in the wastewater flow conduit are dissolved by the flowing wastewater, the tablets in the tablet loading neck descend on the tablet support rod into the conduit, to replace the dissolved tablets. In another embodiment the tablet support rod is slidably mounted in the lid and biased upwardly and as the tablets are dissolved, the tablet support rod moves upwardly through the lid and is either visually inspected or attached to an alarm switch which activates an alarm to indicate the need for replacing tablets on the rod.
