Biological carrier medium
An effective waste water treatment system is the basic prerequisite to ensure environment clean, of which the main process is microbiological degradation of organic matters. Like all creatures, microorganisms need oxygen to survive, and in general, oxygen is acquired through directly injecting air to the waste water. This process can be completed through adding solid surfaces to water container, and the solid surfaces make these microorganisms grow, and retention time longer than that in water. The best carrier of this application can be provided by our company.
Whether this process needs trickling filtration, random packing or biological carrier medium of submerged bed, it must meet the condition.
High specific surface area
Preferable waste water permeability
Optimum dimension and shape based on price and service life
Be easily washed by running water
To ensure that no harmful substance exists in microbial survival
Biological carrier used for MBBR keeps movement under the action of air and circulating water. The density of collective carrier can be adjusted into 1.15g/m3 from 0.95g/m³ based on customer demand, but it will increase with the development of biological membrane on carrier surface. Compared to the trickling filtration or submerged bed, MBBR has a relatively thin biological membrane in biological carrier so that its specific surface area is large, which can ensure that the smaller reaction tower can be built with less investment cost under the premise of equivalent organic matter degradation.
Shape of BIOFLOW 9 makes it provide a larger specific surface area with 800m2/m3, and it is mainly used for waste water with smaller amount of organic matters such as fishpond.
With a relatively open shape, BIOFLOW 30 is used for waste water with moderate amount of organic matters, especially for industrial waste water, for example in paper and paper pulp industry.
Due that BIOFLOW 30 has a larger dimension, screens in the reactor outlet and circulating pump inlet can be designed into comparatively screen mesh, which can reduce the cost of electric pump.
In the condition of higher organic quantity, BIOFLOW 40 should be used, and its dimension and weight is higher than that of BIOFLOW 9 and BIOFLOW 30, so it is necessary to consider wear. However, the shape of packing drum sample make it wear resistance improve largely.
