Let see the video below for general description of New Biotank:

Domestic wastewater is treated follow the principle below:

No.1 ANAEROBIC CHAMBER
Sewage water comes from Kitchen and Toilet, then, they are separated as SOLID and LIQUID. With the support of contact media, ANAEROBIC MICROORGANISMS growing up and do their responsibility to decompose the organic substances of sewage water. The process is called FIXED BED BIO-FILTRATION.

No.2 ANAEROBIC CHAMBER
It repeats the same processing as 1st. anaerobic chamber.
This repeating process ensures completely treatment by microorganism. Also, the process of DENITRIFICATION is going very well at this chamber.

AERATION CHAMBER
This process is a splendid function to do nitrification process effectively.
The AEROBIC MICRO-ORGANISM expedites to further decompose by oxygen supplied by blower. The process is called MOVING BED BIO-FILTRATION.

SEDIMENTATION CHAMBER
The supernatant water will go through out
And remaining sludge will be returned to No.1 Anaerobic chamber as an NUTRIENT SOURCE and for completely proceed the denitrification process.

DISINFECTION CHAMBER
Treated by disinfection and go through out.
