11.1.2 Cleaning agents
The type of cleaning agent selected depends on the degree and type of contamination. For the
most common types of contamination and the suitable cleaning agent, please refer to the table
below.
11.1.3 Process-wetted parts
For stable and reliable sampling, sample preparation system components that come in contact
with the media must be cleaned regularly. The cleaning frequency and intensity depend on the
medium.
Manual cleaning
• Remove minor contamination using a suitable cleaning solution (see "Cleaning solution"
section).
• Heavy dirt can be removed with a soft brush and a suitable cleaning agent.
• In the case of difficult-to-remove contamination, soak the parts in a cleaning solution. Then
clean the parts with a brush.
Manual filter cleaning
1. Use the transport packaging of the filter as the cleaning vessel.
2. First clean the filter for 1 to 2 days in a combination of alkaline (1.5 %) and oxidizing cleaner
(1.0 %).
See documentation on cleaner CY820.
3. Rinse the filter thoroughly with water.
4. Then clean the filter for 2 days in an acidic cleaning solution (1.5 %)
5. Rinse the filter thoroughly with water.
A typical filter cleaning interval, e.g. for installations in the primary clarification system, is
1 week.
