Rehabilitation of Surface Aerators and Replacement of V notch weir for MIT Dmases and new Prempal STPs in Dakahlia Governorate

Project Overview

This project, undertaken for the Holding Company for Water and Wastewater, involves the rehabilitation of surface aerators and the replacement of V-notch weirs at Mit Damsis and New Prempal Wastewater Treatment Plants in Dakahlia Governorate. The project aims to improve the operational efficiency and reliability of the wastewater treatment processes by upgrading critical mechanical and hydraulic components within the treatment facilities. Through rehabilitation works and equipment enhancement, the project supports improved treatment performance, energy efficiency, and sustainable operation of wastewater infrastructure while ensuring compliance with environmental and operational requirements.

Scope of Work

The project includes the rehabilitation and upgrading of essential treatment plant components, including:

  • Inspection, assessment, and rehabilitation of existing surface aerators to restore optimal performance.
  • Replacement of damaged or inefficient aerator components and associated mechanical parts.
  • Replacement and installation of new V-notch weirs to improve flow measurement and hydraulic control within treatment units.
  • Testing and commissioning of rehabilitated equipment and upgraded systems.
  • Inspection and maintenance of mechanical, electrical, and control systems related to aeration and hydraulic structures.
  • Calibration and adjustment of operational parameters to enhance treatment efficiency.
  • Monitoring dissolved oxygen levels and aeration performance to optimise biological treatment processes.
  • Providing technical support during rehabilitation activities and ensuring proper integration with existing plant operations.
  • Preparation of technical reports, equipment assessments, and completion documentation.
  • Ensuring compliance with occupational health, safety, and environmental (HSE) requirements throughout project execution.

Technological Impact

The project enhances wastewater treatment performance through the rehabilitation of key process equipment and the introduction of improved hydraulic control systems. Upgrading surface aerators improves oxygen transfer efficiency, reduces energy consumption, and enhances the stability of biological treatment processes. The replacement of V-notch weirs provides more accurate flow control and measurement, improving process monitoring and operational optimisation.

These technological improvements contribute to increased treatment efficiency, reduced operational failures, extended equipment service life, and improved reliability of wastewater treatment plants. Furthermore, the project supports the adoption of modern rehabilitation practices and sustainable asset management approaches, ensuring long-term performance improvement for Mit Damsis and New Prempal Wastewater Treatment Plants in Dakahlia Governorate.
