Industrial Effluent Treatment for Compliance

Centrally located on Sheikh Zayed Road, the Sheraton Mall of the Emirates Hotel is an iconic part of the Dubai skyline and is directly connected to the Mall of the Emirates, one of the biggest and most famous malls in the country. With its increasing success, the Sheraton chairpersons at Majid al Futtaim Properties Group had approached Clear Water Solutions in 2013 to reduce their water wastage and biological fouling.

The Challenge

Reducing the biological fouling

Our Approach

On-Demand Supply

An Advanced SBR system was retrofitted inside an existing water storage tank in the basement of the building. The drains were diverted using electrically actuated butterfly valves to feed the plant “On-Demand.” With the flip of a switch, the plant has the flexibility to accept some amounts of Sewage during high demand periods.

The Result

First of its Kind Solution

The plant was commissioned as a first-of-its-kind for using biological treatment to reduce the biological fouling and achieve an exceptional quality treated effluent, to be reused easily in the cooling towers.

Design Flow: 70 m3/day

Influent: < 100 mg/l BOD5, < 200 mg/l COD

Effluent: < 5 mg/l BOD5, < 50 mg/l COD


Advanced Sequential Batch Reactors

The ASBR is an enhanced SBR process, which incorporates staged activated-sludge process configurations to operate with continuous inflow of wastewater and increase efficiency and capacity. The process utilizes a simple repeated time-based sequence of operation, which incorporates: Aeration (for biological reactions), Settling (for solids-liquid separation), and Decanting (to remove treated effluent). Completion of these three operations in the sequence described above constitutes a cycle, which is then repeated.

“Clear Water provided our property, the Sheraton Mall of the Emirates, Dubai, with a water treatment system for our cooling towers. Their system has performed very well and they have proven themselves to be a competent and reliable business partner. In a field where problems and excuses are common, the Clear Water team has stood out because they get the job done.”
