Dear Jaber, As no one else has replied to your query, I'll jump in with some out of date information, and a pointer to where to look next. About eighteen years ago, my employers (then called CJB Developments Ltd) sold such chlorination systems to municipal swimming pools. Into the system one fed water, electricity and salt, and out came a solution of sodium hypochlorite that was stored in a large tank and dosed into the recirculated pool water, to maintain the appropriate concentration in the pool. The process involved an electrolytic cell that was purchased from Diamond Shamrock in the States. The advantages are no chlorine gas to worry about (there were several well publicised nasty accidents in pools at that time), and an automatic dosing system that doesn't involve the alternative of tossing expensive chlorination tablets into the pool until the concentration is correct (involving chemical analysis of a sample of pool water). Reliability must be pretty good, as we've recently heard of one of our 17 year old plants that's still in use. CJB stopped selling the systems about 15 years ago as they were not deemed "core business". A search of the 'Net for the trade name "Sanilec" brought up Exceltec International Corporation who sell such systems, so pop along to http://www.sanilec.com where it looks like all your questions will be answered!
