Fluid contact plate

A plurality of fluid contact plates, each of said fluid contact plates comprising a first array of vertical fins provided in spaced relationship;

• a second array of horizontal fins provided in spaced relationship with respect to each other, said horizontal fins intersecting said vertical fins, respectively;
• a first plurality of diagonal fins positioned in spaced relationship with respect to each other, said first plurality of diagonal fins intersecting said vertical fins and said horizontal fins in angular relationship to define a plurality of discreet junctions, respectively;
• a second plurality of diagonal fins positioned in spaced relationship with respect to each other, said second plurality of diagonal fins intersecting said first plurality of diagonal fins, said vertical fins and said horizontal fins in angular relationship at said junctions, respectively, said vertical fins, said horizontal fins and said diagonal fins defining a front matrix surface and a back matrix surface in said fluid contact plate;
• front connecting means provided in said front matrix surface and back connecting means provided in said back matrix surface, said front connecting means adapted to engage said back connecting means for joining first selected ones of said fluid contact plate to each other in front-to-back relationship, said plurality of fluid contact plates joined in vertical, abutting, assembled relationship to define an assembly, with means to pass liquid vertically down through the assembly and means to pass air horizontally therethrough.
