Technologyoverview

Thistechnology adopts a new type of BDD electrodes to generate hydroxyl freeradicals. The generated hydroxyl free radicals react with organics to produceorganic free radicals to continue the chain reaction, or by generating organicperoxides, free radicals further oxidize and decompose organics till degradingthem into final products: carbon dioxide, water and nitrogen.

BDDis an “inert” electrode of diamond alloy, multi-plates or two sides are both utilizable;spacing is small, polarity is alterable; and one processing unit can be expandedto install multi-pairs of electrodes. Therefore, it has features such as largearea, high efficiency, fouling resistance and easy cleaning.

Technicaladvantages

Ø  Utilizing hydroxylfree radicals to react, no selectivity;

Ø  High electrode currentdensity and high oxidation efficiency

Ø  The electrode isstable in physical properties, difficult to corrode, and has long service life

Ø  No electrodeconsumption and no secondary pollution

Ø  The unit isskid-mounted and has a small footprint, easy for transportation

Ø  The unit is highlyautomatic and easy to monitor and operate

Ø  Can be used eitherindependently or in conjunction with other treating processes

Ø  Can treat wastewatercontaining a high-concentration of salts and containing such substances as phenols,naphthols, cresols which are difficult to degrade, or treat wastewatercontaining a high concentration of ammonia, sulfite and cyanide  

Ø  It is most economicalto treat wastewaters with a low concentration of organics, ammonias andsulfites. Traditional technologies are unable to further purify these kinds ofwastewaters.

Applicationfields

Especiallysuitable for treating high salinity wastewater and high organic wastewater,such as pharmaceutical wastewater, printing and dyeing wastewater, landfillleachate, oil field wastewater, waste lye, evaporative crystallization motherliquor, etc.
