The drinking water section of the Ontario Ministry of the Environment issued a revised bulletin in January 2001 regarding chlorinating and contact time of potable water supplies (Procedure B13-3, Section 2.1). Most other provinces have adopted similar standards.

A solution to this new drinking water standard is Hyprescon's inline-mixing chamber or Chlorine Contact Tank (CCT), which can provide the required contact time (please contact us for tank sizing). The diameter and length of the chamber are based on the available pump rate, site restrictions, and a minimum required chlorine contact time. The contact tank is designed to the working pressure of the existing or new distribution system and will be shipped "ready to install" with all the corrosion protective properties of concrete. Perforated inlet and outlet branches, as well as, perforated intra-basin baffles are located in the chamber to prevent short-circuiting and ensure complete mixing. This perforated branch/baffle system represents a "superior" baffling condition (T10/T ratio of 0.7).

Please note that it is Hyprescon's recommendation that the owner/consultant seek MOE approval of each Chlorine Contact Tank prior to manufacture and installation.
