A food company has constructed a new fruit juice production facility, which will generate wastewater effluent that must be treated. A wastewater treatment plant expansion has also been planned; however, unforeseen events have caused a four-month delay in its construction. Without the ability to treat the effluent, the new production line cannot be operated, which represents a loss of €200,000 per week for the fruit company. Rather than accepting the delay, the company chose to turn to a renowned water engineering company to find a solution.
In addition to air blowers, Aerzen Rental Solutions has fine bubble air diffusion grids in its product portfolio, which can transform any tank into an aerobic treatment unit. Our water engineering customer, who has already used this capability in the past, naturally turned to us to install a temporary treatment solution in an existing sludge storage tank that was on-site.
For this process, it was decided to operate according to the principle of SBR (sequencing batch reactor), and this required the following equipment and operations:
- A generator to provide power to the pumps and the blower
- Pumps and pipes to transfer process effluent to a buffer tank
- Pumps for transferring homogeneous effluent into the mud silo
- A 1500m3/h blower and 3 grids of fine bubble aeration diffusers
- Seeding of the basin with sludge, which it had delivered by slurry trucks.
