Congratulations. You have passed the test and completed the Wastewater in commercial buildings
Achieved badges:
01.
Q: When is it ideal to use a lifting station as a pressurised system for wastewater removal in commercial buildings?
A: When sanitary appliances are installed in the basement of an existing building, when space outside the building is limited or when excavation conditions are difficult.
01.
Q: When is it ideal to use a lifting station as a pressurised system for wastewater removal in commercial buildings?
A: When there is a need to remove black and grey wastewater, drainage water and surface water.
01.
Q: When is it ideal to use a lifting station as a pressurised system for wastewater removal in commercial buildings?
A: When storage of wastewater volumes is required over a longer period of time.
02.
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: Constructing a robust foundation, anchoring the building to the underground, or installing a drainage system – or all three in some cases
02.
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: There is no need to reduce the hydrostatic pressure as it adapts automatically to the weight of the building.
02.
Q: What are the approaches that can reduce hydrostatic pressure on your building?
A: Using the help of the local water supply company to once a year pump away the rising ground water around the building.
03.
Q: What does a Grundfos MULTILIFT protect against?
A: Flooding of cooling towers
03.
Q: What does a Grundfos MULTILIFT protect against?
A: Too high concentration of faecal matters in the wastewater
03.
Q: What does a Grundfos MULTILIFT protect against?
A: Backflow and basement flooding
04.
Q: Which inlet options does the Grundfos MULTILIFT offer?
A: DN32-DN100
04.
Q: Which inlet options does the Grundfos MULTILIFT offer?
A: DN50-DN150
04.
Q: Which inlet options does the Grundfos MULTILIFT offer?
A: DN40, DN65, DN100 and DN150
05.
Q: What makes the Grundfos MULTILIFT easy to install?
A: You only need to set the following in the controller: 1) the maximum number of starts/stops of the pumps and 2) the level of the high water level alarm in the controller.
05.
Q: What makes the Grundfos MULTILIFT easy to install?
A: The system comes pre-assembled with a freely adjustable inlet and many other installer benefits
05.
Q: What makes the Grundfos MULTILIFT easy to install?
A: The system comes pre-assembled and all settings in the controller are set from the factory.
06.
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: A lifting station is flexible, easy to service, cost effective, provides protection against flooding and is odour free. It can also be connected to the existing drainage pipe easily.
06.
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: A lifting station is a versatile solution that can handle both black and grey wastewater, drainage water and surface water.
06.
Q: Why is a lifting station an optimal solution for basement refurbishments?
A: The built-in frequency converter makes the lifting station very flexible for fluctuations in the discharge profile of the sanitary appliances.
