Can any body tell what is the diffrence between Sea water chlorination and Electrochlorination? Or is it same?

Question

This question is with refrence to sea water based thermal power plant.

Answer 1

These are two different processes:

Chlorination of seawater is sometimes used to inhibit marine growth within a condenser and other sea water piping. This is done with a chlorine solution ( bleach, calcium HypoChlorite etc.) and a liquid chemical injection pump.
The injection system doesn't have to work 24/7 instead it was better to batch treat the piping. This prevented organisims from adapting to the chlorine. Batch treatment kills off the new growth and prevents adaptation and resistance to chlorine from ocurring.

Electro Chlorination uses high voltage to disassociate salt (NaCl) into Sodium and Chlorine Ions. It is these Chlorine Ions which are used for disinfection the electric current passed through the salinity of the water produces hypochlorous acid (chlorine).

I have seen this system used in a Marine Sewage treatment system where the treated effluent was passed across a high voltage grid. The sanitation system used sea water for flusing so there was plenty of available salt. When the ship operated in fresh water salt needed to be added to the collection tank to provide the salt or a seperate chlorination system needed to be used. Either rock salt was flused down a toilet or a salt block was added to the tank


I do not belive that electro chlorination would be effective in the large flow and cross-sectional area of a sea water cooling system. The units I have seen pass the water to be treated across flat plates spaced close together. This provides and area where the newly formed chlorine will interact with the effluent rather than recombine downstream.

Answer 2

Sea water chlorinators are used to keep the cooling water systems free from pathogens, algae and mussel growth. So you can chlorinate sea water. They are the same.

Answer 3

To understand the difference between the Roman Catholic Church and the Orthodox Church you have to understand how the schism between them came to be: it resolved around the word "filioque" ("and [from] the son") that was added in the Roman Catholic Church to the Nicene Creed (which is thought be some to be left unchanged). Because of this the Catholic Church encountered a schism and the Roman Catholic Church became the dominating Christian Church in the West, while in the East the Catholic Church laid claim to the title "orthodox" ("right thinking", thus claiming that their interpretation of Christianisty was the right one and that the Roman Catholic Church went astray). But the Orthodox Church doesn't deny the Apostolic Succession of the Roman Catholic Church and vice versa.
