DEVELOPMENT OHMIC HEATING SYSTEM FOR SEA WATER DESALINATION

AND SEWAGE WATER TREATMENT

Part of 1st report

Riyadh, January 13th 2009

PRINCIPLE

USING GENERATE HEAT FROM OHMIC HEATER TO EVAPORATE WATER

Qgen = [∆ v]2 ƍ

where Qgen = energy generation

∆ v = the voltage gradient

ƍ = electrical conductivity

USING CONDENSER TO CONDENSE VAPOR

MAIN COMPONENTMAIN COMPONENT

OHMIC EVAPORATOR CONDENSER

DEVELOP AND ANALYSIS SUITABLE TYPE OF THESE COMPONENT BOTH FOR SEA WATER DESALINATION AND SEWAGE WATER TREATMENT
