Theoretical principles of electrolysis treatment

In the electrolysis treatment, when electric energy is supplied through the electrode plate to the organic wastewater containing electrolytes (Seawater, NaCl), electron is directly exchanged at the interface between the electrode and the solution The wastewater is treated by an electrode reaction of oxidation, reduction and decomposition, and precipitation, and an oxidation reaction by hypochlorous acid (HOCI) and ozone (O3), which are reaction products. Sodium chloride After electrolysis treatment, the strong sterilization power of hypochlorous acid generated on the electrode surface causes oxidation to the organ wastewater, which is purified and sterilized. And it is generated during electrolysis Due to the rise of fine hydrogen gas, floating solids and colloidal suspended substances in water are separated and treated.

Comparison with other methods

Sortation	Active sludge method	R/O system	S.B.R	Electrolytic treatment system
Principle	Organic matter control using microorganisms	Reverse osmosis	Accompanied by reaction, precipitation, etc. in one reaction tank	Electrolysis
Response to load changes	If inflow and water quality fluctuations are large, efficiency is likely to decrease	Strong against load fluctuations	When installing the automatic control system, it is resistant to load fluctuations within a certain range	Strong against load fluctuations
Nutritional Salt Removal	The conditions such as the ratio of C:N:P must be met.	Have an excellent removal rate	Have a relatively good removal rate	Have an excellent removal rate
Conditions of the site	A large site is required because a reaction tank and a precipitation tank are required.	As there are no civil engineering structures other than flow control tanks, less land is required	Reaction and precipitation take place in one tank, so relatively little	The reaction time is within 10mm, so it takes very little space
Merit	The installation and operation costs are low.	Easy to operate and small site area. It is advantageous for small and non-degradable wastewater.	Power can be minimized by controlling the reaction time according to the flow rate	Easy to operate and small site area. It is advantageous for small, non-degradable wastewater.
Weakness	Driving conditions are difficult and a separate nutrient salt removal facility is required	The cost of membrane replacement is the largest in the event of faulking, depending on imports for parts that are not produced in Korea	A rear-end facility is required to adapt to a high-concentration organic material treatment system.	Drugs should be injected into wastewater that lacks electrolytes.
