Discussion

Situation

Egypt is strongly influenced by tourism. In addition to the numerous sights, the country offers an interesting culture. Around 13 million foreign visitors travel to the country every year, making tourism one of the country’s largest economic sectors. The Mediterranean region in particular offers numerous visitors a place to relax.

A Mediterranean resort in Alexandria offers its visitors a comfortable place to relax. On the grounds are villas of various sizes, an indoor wellness area, its own shopping mall, numerous restaurants and direct access to the sea. Wastewater is produced on the entire site, which the owner wants to reuse to irrigate the green areas on the grounds. In addition to the hygienic wastewater from the villas, there is also wastewater from the kitchens of the restaurants and the wellness area.

Problem

The challenge of this project was, on the one hand, the almost invisible construction of the sbr system. As the Mediterranean resort is home to guests all year round, the construction work was not allowed to disturb them. Nevertheless, the sbr system was to be located close to the resort, as the owner wanted to avoid long transport routes. On the other hand, the sewage treatment plant had to be low-maintenance and reliable, as the Mediterranean resort has hardly any skilled workers who can repair faults on site.

Solution

The ClearFox® team visited the Mediterranean resort on site. The client built concrete tanks in which the staff installed the sbr system technology. The focus was on biological wastewater treatment: an aeration system supplies oxygen to the microorganisms in the wastewater, which convert the dissolved substances in the wastewater into secondary sludge. This settles at the bottom of the plant and thus separates from the treated water. To further reduce the volume of the sludge, the ClearFox® team offered the Mediterranean resort a sludge dewatering unit to reduce the cost of removal. Since the client reuses the water for irrigation, after the first treatment stage the water first flows into a filtration unit and then into a disinfection unit. The engineers accommodated all technical components such as the control system, sludge separator or dosing unit in one container. In addition to the overall project planning, the ClearFox® team also took over the project planning, installation and commissioning.

FAQ

Yes, the SBR system is flexible and can be individually adapted to the needs of your project. Whether hotel complexes, resorts, residential complexes or industrial facilities - the technology can be scaled and adapted to different wastewater compositions.

SBR technology is low-maintenance and reliable. The system is automated and requires only occasional inspections and minimal interventions, which can also be carried out by non-specialist employees.

The duration depends on the size and individual requirements of the project. Typically, a plant can be installed and commissioned within a few weeks after the concrete tanks have been built or the system modules have been delivered.

After biological purification by the SBR system, the water passes through a filtration and disinfection unit. After that, it is hygienically safe and can be used to irrigate green spaces or other non-drinking water applications.

Yes, we offer comprehensive support, including remote monitoring, maintenance contracts and training for on-site personnel, to ensure the plant remains reliably operational over the long term.
