Abstract:
A distributor plate assembly for crossflow cassette filtration appliances, said distributor plate assembly being generally rectangular to receive at least one filtration module, said distributor plate assembly comprising:a middle plate member having a front and rear surface, a first and second side wall and a first and second edge wall; a feed duct extending from said first side wall through said middle plate member for introducing a fluid into said distributor plate assembly; a plurality of feed orifices located on said front surface of said middle plate member, said feed orifices being in fluid communication with said feed duct via a plurality of feed connecting ducts; a residue duct extending from said first side wall through said middle plate member for discharging a residue fluid from said distributor plate assembly; a plurality of residue orifices located on said front surface of said middle plate member, said residue orifices being in fluid communication with said residue duct via a plurality of residue connecting ducts; a plurality of upper filtrate orifices arranged on the front surface of said middle plate member parallel to said first edge wall, said upper filtrate orifices being in fluid communication with upper filtrate connecting ducts; a plurality of lower filtrate orifices arranged on the front surface of said middle plate member parallel to said second edge wall, said lower filtrate orifices being in fluid communication with lower filtrate connecting ducts; an upper plate member having a front and rear surface, a first and second side wall and a first and second edge wall, said first edge wall of said upper plate member being located adjacent to said first edge wall of said middle plate member; an upper filtrate duct extending from said first or second side wall of said upper plate member being in fluid communication with an upper longitudinal filtrate duct orifice; an upper filtrate collecting chamber disposed between said middle plate member and said upper plate member, said upper filtrate collecting chamber being in fluid communication with said upper connecting filtrate ducts and said upper longitudinal filtrate duct orifice to allow a filtrate to pass from said filtration module through said distributor plate assembly; a lower plate member having a front and rear surface, a first and second side wall and a first and second edge wall, said first edge wall of said lower plate member being located adjacent to said second edge wall of said middle plate member; a lower filtrate duct extending from said first or second side wall of said lower plate member being in fluid communication with a lower longitudinal filtrate duct orifice; and a lower filtrate collecting chamber disposed between said middle plate member and said lower plate member, said lower filtrate collecting chamber being in fluid communication with said lower connecting filtrate ducts and said lower longitudinal filtrate duct orifice to allow a filtrate to pass from said filtration module through said distributor plate assembly.
