A water treatment plant in Saudi Arabia required quicklime storage for water softening. Requirements: hermetic sealing to prevent air slaking, dehumidified aeration, corrosion-resistant construction, and reliable discharge for the lime slaking system.

Manxing provided 2 x 500t hermetically sealed steel silos with internal epoxy coating. The aeration system uses desiccant-dried air (dew point -40°C). Temperature monitoring detects any hydration reaction. The silos are equipped with pressure/vacuum relief valves and desiccant breathers. The discharge system feeds the lime slakers at a controlled rate.

The system has been operating since 2022 with no lime degradation issues. The desiccant aeration system has proven highly effective in the Saudi climate (ambient humidity 60-80%).
