Sealife Istanbul – Achieving more with less
Project ID: Location Istanbul Company Merlin Entertainments Year 2019 Water Saltwater Size of Aquarium: 5 million liters ATO Energysaving, with Merlin Entertainment and other partners, implemented an energy-saving initiative at Sealife Istanbul for its 5-million-liter ocean tank. The Challenges: High energy consumption due to compromised hydraulic lay-out, needing significant amount of energy to get circulation (2x 37kW, 2x 30kW & 4x 15kW). Lack of bottom and side drains in the tank design, leading to inefficient waste capture and excessive detritus buildup, requiring daily siphoning. Protein skimmers underperformed as waste failed to reach the LSS. Ineffective biological filtration caused by insufficient waste retention time in the filters, caused by not well spreading of water on the bio filter area Significant water and salt usage for siphoning and backwashing The Solution: Replaced sand in the filters with AFM® (Activated Filter Media), enhancing filtration and stabilizing ORP (Oxidation-Reduction Potential) levels, enabling automatic ozone generator shutdown and reducing energy consumption. Implementation of 17 highly efficient AFC400 propeller pumps and adjustments of speed to the existing pumps and taking offline the 37kW pumps. Optimized water flow with AFC400 pumps, to keep detritus suspended, reducing daily siphoning demands. Enhanced retention time and even water flow through biological filters for better nitrification performance. Reduced backwash intervals, saving water and salt. Pumps energy usage 1’250 MWh/year 550 MWh/year Power use of pump of filters 200 MWh/year <100 MWh/year Backwash interval Twice a week Once a week Backwash volume 2500m3/year 600m3/year Water to be reclaimed 10 million liters 2.4 million liters Circulation in the tank 2.1 million liters/h 3.4 million liters/h Results: 700’000 kWh are saved per year The optimized circulation system increased water movement by over 50%, improving cleanliness within the tank and reducing detritus buildup. The reduction in detritus accumulation decreased the need for siphoning and backwash operations, which in turn saved water and salt. The frequency of backwashing was halved. AFM® improved water quality and stabilized ORP, minimizing the need for chemical additives such as ozone. FormaEin Bild, das Konzert, Aquarium enthält.

Golden Nugget, Las Vegas
AFM® delivered 100% water clarity 3x faster than silica sand in backwash recovery filters, maintaining optimal flow rates all day, and has now been implemented in every exhibit.
Belgrade penguin exhibit
With AFM® filter media, Belgrade Zoo’s penguin exhibit ensures the best water quality and therefore the least impact on the penguins health.
Dolphinarium Madrid
With AFM® filter media and ACO, water clarity improved 4-fold, chlorine levels dropped by 50%, and air backwashing became a thing of the past.
