Depending  on what you are trying to achieve, purpose built photo catalytic oxidation / disinfection might be a long term viable alternative.   Happy to assist.

Electro-chlorination can be either with a membrane system (producing chlorine gas or a high concentration of hypochlorous acid), or non-membrane (producing a lower concentration of hypochlorous acid, typically < 1%).  The non-membrane systems  have the advantage of low maintenance and lower operational attention, with the feed water quality being less stringent.  Either system requires cleaning of the electrodes (acid wash) from time to time, while the membrane systems also require membrane flushing and replacement.  Pre-softening the water helps to minimise scale formation on the electrodes.

Hi
Different scenarios and aspects to be considered:
- if the system is for drinking water: all components must comply with local regulations, in USA is  NSF or equal
- there is more flexibility is the application is for waste water or industrial effluent
On either case, always is good to compare CAPEX and OPEX and safety issues
CAPEX for gas chlorination can be high if emergency infrastructure is required, like scrubber systems in case of emergency leaks. Gas chlorination close to schools and/or communities is always a concern!
OPEX for gas chlorination we all know are lower as compared with electro chlorination             (man hour + salt+ power+parts) For industrial or WWTP effluents sea water can be an option for offset salt consumption.
Not a bad idea to include other options like liquid bleach, UV in your analysis for your disinfection needs

Envirolyte Generators typically produce up to 95% Hypochlorous Acid (HOCL), its efficacy is 100 to 300% more effective than Sodium Hypochlorite (SH). Our low salt and low energy machines provide very competitive running costs, as does our whole range of generators.
HOCL is environmentally friendly and is a fully biodegradable product that offers excellent health & safety benefits compared to SH.
