Procedure for Cleaning the Inside of Tanks and Purification
Tap water is run in and softened to 0 degrees of hardness with the help of decalcification tablets.
|Branching the Pipe in Two
Water with 0 degrees of hardness is fed directly into the boiler.
The second pipe is mixed with tap water attaining a hardness value of 4 degrees. This pipe feeds a 3,000 litre capacity tank.
|The 3,000 Litre Tank
This tank supplies water to the spray-heads, handguns and sanitation facilities.
The boiler generates a steam pressure of 110 °C. It is checked and purged by the staff daily. The steam is stored in a 3,000 litre capacity insulated tank.
The boiler contains a heat recovery unit yielding 40-50 °C which is stored in a 25,000 litre capacity insulated tank.
One of these pumps is in operation. The second is used as a back-up since the facility is inoperable without a pump.
The operational pump is exchanged weekly so that the pumps remain in regular use and do not block.
|High Pressure Pumps - Switch Cabinets - Heat-exchanger
The facility has 4 high pressure pumps; 2 feeding the spray-heads and 2 feeding the handguns. Two heat-exchangers that heat the water are situated above the high pressure pumps.
The switch cabinets house the control system for the complete computer monitored facility. The computer monitoring determines and notifies every defect.
The compressor produces the air to operate the pneumatic control valve.
The use of dosing pumps ensures that the correct amount of soap is employed for every wash. The computer raises an alarm if the pre-programmed amount of soap is not added to a wash.
|IBC Container Cleaning Facility
A spray-head with a throughput of 30 litres per minute is available for cleaning IBC Containers. Soap can also be added to the wash, if required.
|Wash Facility Computer for Lines 1 and 2
If desired by the customer, the wash programme can be saved on the computer in reception. A previously saved wash programme can then simply be started from the computer in the wash facility.
The facility has two lines each with 5 spray-heads and 2 driers. 4 of each lines spray-heads have a throughput of 50 litres per minute. 1 spray-head which is used for cleaning containers with an opening has a throughput of 100 litres per minute.
Pipes and hoses are cleaned with the aid of this spray-jet.
|External Silo (right)
Liquid waste is initially stored in a 50,000 litre capacity tank. Subsequently it moves into our purifier.
The purifier chemically cleans the liquid waste. Liquid waste from the external silo flows into the first chamber, here it is mixed with additives via an agitator. Purification takes place in the second chamber. The purified water runs into the drainage system. Fatty substances are pumped into the sludge silo.
|Sludge Silo (left)
The tank has a capacity of 30,000 litres. When the tank is full, the waste is transported to a biogas plant for disposal.
