BIOGEST received in 2011 the order for the Vacuum flushing System Equipment of a 45.000 m³ retention tank at Greater Irbid WWTP Stage II Wadi Shallalah in Jordan. During rain fall season, heavy rainfalls will be collected in the Wadi Shallala reagion. To prevent overload of the wwtp a retention tank with the dimensions of 50 x 75 m BIOGEST was constructed together with a very effective and BIOGEST developed vacuum flushing System in 2013.
This large tank was divided in 5 lanes of each 10 m width. That way the mechanical equipment could be enormously reduced to a minimum, in comparison to other systems on the market. The great depth of the tank could be used to optimize the flushing water volume. This System has no moving parts in contact with waste water, is operating automatically and do not need maintenance inside the tank. The Level sensor where chosen as well contact free. No other cleaning system is so effective, widely applicable and user-friendly like the vacuum flushing System. The maintenance is therefore easy to be done by local operator staff.
These have been the decisive points for using the BIOGEST Vacuum system for this project in the desert area. The maintenance effort is a minimum and easy to handle for the Operator, without entering the tank. BIOGEST has already delivered thousand of this system, worldwide and to different climate zones (from Canada to NZ). It is a most reliable and simple flushing system that been proofed for many years.
