Greater Efficiency in the Use of Reclaimed Water at Montazah Gardens

Greater Efficiency in the Use of Reclaimed Water at Montazah Gardens

Montazah Gardens

Montazah Gardens, in Alexandria, is an iconic historic site that combines Egypt’s royal heritage with a unique natural setting on the Mediterranean coast.

Covering an area of more than 150,000 m², these gardens represent an important part of our landscape and cultural heritage, and their preservation requires efficient and sustainable water resource management.

The Challenge

The water system had difficulty maintaining adequate water quality under conditions of high demand:

  • The presence of total suspended solids (TSS) that were affecting water quality.
  • The need to manage high flow rates efficiently.
  • Recurring problems with blockages and operational shutdowns.

In addition, the project presented specific challenges:

  • Need for a large-scale filtration system (30 units).
  • Variability in the quality of the incoming water.
  • The need to ensure a balanced flow rate distribution among all filters.
  • Limitations of conventional systems, which suffer from high head losses and frequent clogging.

The challenge was to design a robust, automated, and easy-to-manage solution capable of operating reliably on a large scale.

The Solution

AZUD implemented a comprehensive filtration solution based on 30 automatic disc filters (130 microns), configured in a modular system.

The project’s development included:

  • Analysis of hydraulic requirements and water quality.
  • System design to ensure a balanced flow rate distribution among the units.
  • Installation of filters in a scalable modular configuration.
  • Implementation of an automatic self-cleaning system using backwashing, activated by differential pressure (ΔP).
  • System integration with a PLC control panel for fully automated operation.

This solution enables efficient filtration of fine particles and continuous operation with minimal manual intervention.

Benefits of the Solution

The implementation of the system has significantly improved water efficiency and management in the gardens:

  • A significant improvement in water quality.
  • Reduction of blockages and operational disruptions.
  • Stable operation even under high-demand conditions.
  • Reduction in water consumption during backwashing.
  • Reduction in operating and maintenance costs.
  • Easy system management despite the large number of units.

Overall, the solution ensures efficient and sustainable water management, which is key to the preservation of this historic site.
