For wastewater treatment facility, odour control unit capacity is estimated based on the two parameters: ·       The Air volume of odour causing process tanks ·        Air exchange factors to be considered for the process tanks While estimating the air volume of the process tanks, if it is a fixed water level tank, freeboard air volume shall be considered; if it is fluctuating water level, it is advised to consider the air volume from the lowest water level . Air exchange factors are very critical in designing the odour control system capacity and which impacts the size and efficiency of the odour removal. Most of the regional municipalities have made clear guidance on the air exchange factors to be considered while estimating the odour control system capacities. Typically, for inlet works, air exchange factors are considered in the range of 12-15 of the volume of the air. And for the sludge treatment facility, it will be 6-12 of the volume of the air, it depends on the v

  Most of the process engineers in the wastewater treatment industry and environmental industry are utmost clear about the treatment process of wastewater and its optimization but for those having unclear knowledge, any action could be futile.     Fixing clarity when implementing an odour control system at the facility is a favourable business key. Here are top-rated questions to be asked when exploring potential odour control system suppliers globally; 1. Which is the odour control technology offered? There are many proven odour control in wastewater treatment ; widely used are: ·        Activated carbon adsorption system ·        Chemical scrubbing system ·        Biological oxidation system 2. What are the process tanks, they have considered for odour removal? In wastewater treatment plant, potential odour generating areas are inlet works including but not limited to wastewater receiving channel, pumping station, screening & grit removal channel, etc. and s
