The apparatus includes a separation membrane element having an axial dimension, a membrane support structure having the element therein, and means for vibrating the membrane element (hydrodynamically or using motors) in the axial dimension.
Claims18
A membrane separation apparatus utilizing vibration of a membrane module having an axial dimension for treatment of effluents flowed through said apparatus by means of fluid ports, said apparatus comprising:
- a membrane support structure having the membrane module receivable therein and including an adjustment plate at an upper section thereof and a retainer ring having at least a first port therethrough at a lower section thereof;
- and
- vibrating means associated with said support structure for hydrodynamically activating vibration of the membrane module along the axial dimension in said support structure, said vibrating means including a fluid pump and a spring, said fluid pump connected with said first port and said spring located in said support structure between said adjustment plate and location of the membrane module.
A membrane separation apparatus utilizing vibration of a membrane module having an axial dimension for treatment of effluents flowed through said apparatus by means of fluid ports, said apparatus comprising:
- a membrane support structure having the membrane module receivable therein and including an adjustment plate at an upper section thereof and a retainer ring having at least a first port therethrough at a lower section thereof;
- and
- vibrating means associated with said support structure for hydrodynamically activating vibration of the membrane module along the axial dimension in said support structure.
A membrane separation apparatus utilizing vibration of a membrane module having an axial dimension for treatment of effluents flowed through said apparatus, said apparatus comprising:
- a membrane housing including an adjustment plate at an upper section thereof and a retainer ring having at least a first fluid port therethrough at a lower section thereof, the membrane module receivable therein;
- a piston structure slidably retained in said lower part of said housing, one end of the membrane module receivable adjacent thereto, said piston structure between said first fluid port and the module;
- a ring structure slidably retained in said upper part of said housing, an opposite end of the membrane module receivable adjacent thereto, said ring structure between said adjustment plate and the module;
- a spring maintained in said housing between said ring structure and said adjustment plate;
- and
- a fluid pulsing pump for pulsating a high pressure water jet connected at said first fluid port of said housing.
