Water consumption in Oman is gradually increasing and expected to rise by 52% percent in 2022 as compared to 2018, therefore sewage and sludge production are increasing proportionately.
Although sludge treatment is a growing problem worldwide, there is no clear and defined consensus regarding the best utilization strategy.
EnCata was challenged with elucidating the two scenarios:
Additionally, the dry matter content (which is subject to sewer operations, climate, and effluent type) plays an important role in the process and financial modeling.

Mass / material balance
In this technical and business feasibility study, the EnCata team compared 6 different technologies for sludge treatment:
All 6 technologies were scrutinized for top-level equipment costs, material balance, business model operations, CAPEX, and financial outputs. We found that only 2 technologies are feasible/profitable to pursue. Further work in this project was in detailing the biogas digestion and cement-kiln co-firing technologies.
In this project, the technical and business analysis team of EnCata produced a detailed study for the client
candidate technologies considered in this feasibility study
model plants were chosen for further analysis
MMBTU Energy saving can be achieved per year with a 100 ton/day sludge utilization
