摘要：A tank top pretreatment unit and assembly comprises a treatment unit (30)installed inside a water treatment tank (12), such as a water softener tank, and in the topof the tank for treating the water either prior to its treatment with the primary treatingmedium (14) in the tank or following such treatment. The treatment unit (30) includes aplurality of chambers (32) which are configured to contain a finely divided watertreatment medium (42) of a different kind than the primary treatment medium (14).Some of the elements may be arranged in series, but many or all are arranged in parallelflow which reduces the pressure drop of the water across the treatment unit, and theinlet openings (76) to the chambers and outlet openings (78) from the chambers areelevationally spaced from each other and the area of the outlet openings is less than thearea of the inlet openings to maximize contact and dwell time in the chambers. A housing(12) is also disclosed which surrounds and contains some or all of the chambers (32) topermit positioning of the treatment unit (30) beneath the level of the primary treatingmedium (14).
