How to pack old ULPA for transshipment? Replacing pollution control and disposal processes

oldULPA filter packaging and transportation should be formulated based on actual contaminants and on-site management requirements. Ordinary dust filter elements and filter elements exposed to special process contaminants cannot be disposed of in the same way without evaluation. The disposal of old parts is often regarded as the final action of the replacement process. In fact, it is a component of the same set of pollution control as disassembly and loading of new parts. If the disposal method is improper, the previous protection will become invalid again. Aili Industrial's packaging system is two-way through: how to pack the new filter element in layers, the old filter element has the packaging method corresponding to the size and sealing level to follow. The project party does not need to temporarily find a container or make a temporary packaging plan on the day of replacement.

1. First confirm the nature of the pollution: no exposure history can be seen from the appearance.

Check the use area, contact objects and maintenance records, and let the project determine the protection, packaging and disposal procedures. The degree of contamination cannot be judged solely by the appearance of the filter element.

Used filter elements from the same batch are used in ordinary clean areas and areas exposed to special prnce data.When HEPA/ULPA filters are delivered, the model and usage scenarios will be recorded according to the application area. The project team can combine these records with the local location ledger to determine the exposure history of the old parts, instead of waiting to dismantle them to see their appearance before deciding on disposal methods. The relationship between levels and filtering requirements can be found inISO cleanliness level comparison。

2. Control diffusion after disassembly: packaging must be completed at the exit position

Pack as required and protect packaging integrity to avoid squeezing, shaking or disassembling filter media in clean areas. The transport route should be separate from new filters and workpieces.

After the old parts are removed from the installation location, the sooner they are packaged, the better. If the dust brought out by the filter element during the exit process is moved to the buffer zone before being processed, the intermediate path will form a diffusion source. Aili Industry isEFU equipment end fan filter unit andThe structural design of the detachable FFU indicates the exit direction of the filter element, making it easier for the site to arrange the packaging position and undertake tooling at the end of the exit path, so that the packaging action can be completed immediately after the disassembly action. For partition management of packaging of old parts and unpacking of new parts, please refer toULPA ultra-high efficiency filter FAQ and selection guide。

3. The packaging specifications must be matched according to the actual size of the old parts, and cannot be improvised.

The size of the old filter element packaging bag or box should match the shape of the filter element. If the package is too large, the old parts will shake during transportation, and the sealing surface and outer frame may be damaged due to collision; if the package is too small, forcibly inserting it will squeeze the filter material and increase the risk of pollutant leakage.

Aili Industry isThe delivery packaging of large-size non-standard ULPA filter models adopts a layered structure and indicates the overall dimensions. This set of packaging information can be directly used to configure the packaging scheme for old parts with corresponding specifications; the packaging specifications of standardized models can also be used as a reference for packaging old parts. For the corresponding relationship between packaging specifications and filter element size, please refer toHEPA FAQs and Selection Guide。

4. Keep transfer records: old items must also have their identities and whereabouts

Mark the origin, disassembly time and processing status, and hand over according to site regulations. For managed pollutants, corresponding requirements should be followed and not treated as general waste.

If the location, removal time and processing status of the old parts are missing, there will be no basis for subsequent traceability. Aili Industry isWhen the ULPA ultra-high-efficiency filter is delivered, it can cooperate with the project party to establish a corresponding record of points and numbers. When dismantling old parts, they will be marked with the same number to form a corresponding relationship between the loading of new parts and the withdrawal of old parts; matchingThe FFU computer group control system can record replacement time points to facilitate correspondence with old parts transfer records.

5. Related questions and answers

Can the old filter material be removed to reduce its size?
Dismantling may release contaminants and should not be performed on site without evaluation. The disposal method should be determined by the project according to the nature of the pollution.

There is no obvious dust on the used filter element in the process area. Can it be disposed of as ordinary waste?
You can't judge by appearance alone. Exposure history should be checked before packaging and disposal decisions are made.

Can the packaging of old parts wait until they are moved to the buffer?
Not recommended. Encapsulation should be completed at the exit position as much as possible to reduce the spread of brought-out dust on the transfer path.
