Abstract
A water tub includes a circulation system utilizing a high permeability type (HPT) filter to filter water being pumped to form water jets. In some instances, HPT filters are used to filter all of the water circulated through a water tub, including water being utilized in therapeutic water jets. In some instances the described water tubs have a flow rate to filter material ratio greater than 1.
Claims18
A water tub circulation system causing water to flow through a water jet, the water tub circulation system comprising:
- a high permeability type filter positioned in the circulation system to filter water before it passes through the water jet.
A water tub including a water circulation system comprising:
- at least one jet pump that is high capacity water pump having a GPM rating of at least 120 GPM;
- at least one high permeability type (HPT) filter;
- and
- at least one feed line establishing one or more water flow paths between the at least one HPT filter and the at least one jet pump.
A method of water tub water filtration comprising using at least one HPT filter to filter at least some of the water circulated through a water circulation system.
A water tub comprising:
- at least one filter and at least one flow path between the filter and a pump wherein water flows through the filter, flow path, and pump during a particular operating state;
- and
- the flow rate to filter material ratio of the at least one filter and at least one flow path during that operating state is greater than 1.
