Over the past few decades there have been significant change in the discharge standards required to be met for both industries and municipalities. Additionally, increase in volumetric as well as upgradation of existing activated sludge to the plants have forced the facilities manage to upgrade their plants to meet the treatment targets.
Conventional Approach And Its Limitations
Conventional approach of upgrading existing activated sludge plants for higher capacity or removal requires addition of new activated sludge basins to retain more biomass/MLSS and thus increase treatment capacity. However, this approach requires additional construction of new aeration tanks and clarifiers along with its associated infrastructure. In existing set up where land is scarce , providing additional space for construction of new basins or reactors becomes very difficul
Disadvantages Of Conventional Approach:
- Construction of new Aeration and clarifier basin
- Additional land/space requirement
Upgradation of existing activated sludge with Levapor IFAS: Maximum Utilization Of Existing Infrastructure Without Adding Foot Print
In contrast to conventional approach, Levapor IFAS upgradation of existing activated sludge doesn’t require construction of new basins and clarifiers. Instead by adding Levapor carriers to existing basins at 12-15% volumetric filling ratio, existing plant biomass /MLSS can be significantly increased to meet the higher treatment requirement. Almost all activated sludge process configurations can be converted in to Levapor IFAS based process to achieve higher treatment capacity
Advantages Of Levapor Ifas Upgrade
- No additional civil construction
- No additional space requirement
- Same flow sheet and operating as conventional activated sludge
- Higher MCRT And MLSS with the same size of basin
- Better settling properties and clarifier performance
- Better removal efficiencies
