Judgment Index of MBBR Filler

MBBR filler is a microbial carrier applied in the MBBR process, mainly providing a suitable environment for microorganisms.

Judgment indicators of MBBR fillers:
Extracellular matrix adhesion
Operating situation of the adhesion work ability of extracellular matrix — the most important indicator of the most important indicator of the filling of the filling charging, the amount of microorganisms = the maintenance area of the maintenance (related to the design scheme of the filling charging) The characteristics of filling the charging).

Filling material characteristics
Filling features — Comment on the most important indicator value of filling charging microbial adhesion.
(1) Filling surface characteristics
1. The surface structure: Generally, the roughness is large, and the membrane speed is faster.
2. Power difference between the surface layer of the membrane: The general microbial bacteria are negative, and the surface layer of the filling is suitable for the growth and development of positive electricity.
3. Water absorption: Microbial bacteria are water absorption particles.

(2) Hydrological characteristics
1. Pole rate: The volume of the filling is good, and the pore rate is high.
2. Specifications: endanger the flow of flowing water and cyclones.

(3) Dust collection characteristics: related to the relative density of filling charging. The relative density of filling the charging should be 0.97-1.03. Small hydrolyzed acidized pools or mix can be completed.
