The 2 stage Chemical system collects odors generated by the sewage treatment plant and removes the odor and VOCs by chemical reactions using second-stage cleaning fluids (NaoH,H2SO4, etc.).
Double-stage Chemical Deodorizer:
Double-stage chemical deodorizer is composed of one wash tower divided by two stages that uses different types of chemical liquids; so it reduces the installation area while enhancing the deodorization efficiency.
- 1st stage acidic odor removal : It sprays a chemical liquid onto odors in order to remove acidic odor(ex.H2S).
- 2nd stage alkali odor removal : upon inflowing of the odor of which the acidic odor has been removed, it sprays an other chemical liquid to remove alkali odor.
- Porous panel : A porous reaction panel is a panel with numerous pores so it pneumatizes a odor gas without leaking a chemical liquid. With pneumatization of a odor gas, the surface area of odor gas contacts with chemical liquid expands, in turn raising its removal efficiency.
Yusung twins has two medicinal wash towers that each sprays different medicinal liquid so it is highly suitable for a highly-concentrated foul smell. Especially, since it is equipped with a device for removal of a salt, generated from the use of a medicinal liquid, its foul smell removal efficiency does not degrade over time.
- 1st washtower–removal of primary odors : By analyzing components of odors, we choose a proper chemical liquid to remove them.
- 2nd washtower–removal of remaining foul odors and disinfection : It sprays CLO2 to remove any remaining unpleasant odors and disinfect.
- Porous panel : A porous reaction panel is a panel with numerous pores so it pneumatizes a odor gas without leaking a chemical liquid.
