Preconditioning
For pre-conditioning and pre-collection we have various methods and equipment – such as heat exchangers, humidifiers, venturi scrubbers, fabric filters and quench coolers – in our program to create ideal conditions for industrial odour control like dust removal, humidity and temperature control.
For optimal result of any biofilter, three parameters should be controlled. Firstly, the performance and life span of the system is very much related to temperature. Secondly, drying out of the organic biofilter can occur if the relative humidity of the incoming air is not sufficient (100%. Thirdly, excessive dust in the incoming air can cause clogging of the organic biofilter material.
The single or combined effects of temperature, relative humidity and dust together often leads to clogging causing inhomogeneous flow, preferential flow channelling, poor utilisation of all of the organic biofilter medium and reductions in odour removal efficiency. It can also result in a significant decrease in the effective life of the organic biofilter medium. Faster replacement adds extra costs and it is inconvenient to do on a regular basis. That’s why the contaminated air is often pre-conditioned and pre-collected.
