Homogenisation plant and technology
The following system was built for the homogenisation test series (Figure 1). A UADA module with 25 m³/h and an acoustic plate 204 (2.0 x 4.0 mm). There is a pressure gauge at the inlet. A hose connection connects the module to a pump.
The pump is also connected to an IBC via a hose. Another IBC for the product is located after the module. This is also connected to the module via a hose. The diagram is shown in Figure 2.

Results of WPPO homogenisation
The homogenisation test was carried out on 6 June 2025. Two samples were taken. One sample was taken before homogenisation, the other after two homogenisation (see Figure 3 and Figure 4). The sample bottles werephotographed again on 7 July 2025 (see Figure 5 and Figure 6).

Figure 4: WPPO after homogenisation
After homogenisation, there are no longer any large particles or droplets in the sample, as can be found in the unprocessed WPPO. The sample bottles were photographed again on 7 July 2025 (see Figure 5 and Figure 6).

Figure 6: WPPO after homogenisation
After one month of storage, no differences were noticeable. A test with filter paper was alsocarried out on 7 July 2025. In each case, 200 ml of each sample was used. Kitchen rolland coffee filter paper were used as filters. The samples are dried andanalysed after one day. The results of the test can be seen in the photos (Figure 7 and Figure 8).

Figure 8: Results of the test with filter paper (homogenised WPPO)
Large dark spotscan be seen on the paper after the test with unprocessed WPPO (Figure 7).
During filtrationthrough the coffee filter paper, a sample of the unprocessed WPPO was filteredwithin 1 hour/12 minutes/32 seconds. The homogenised WPPO was filtered in 15minutes/27 seconds.
After emptyingthe sample bottles containing the filtered samples, different sedimentationscan be seen (see Figure 9 and Figure 10).
This also shows that thedelivered WPPO leaves significantly more oil residues in the sample jarscompared to the homogenised WPPO
leavessignificantly more oil residues in the sample jars. With the considerableimprovement in the quality of the WPPO achieved by the UADA module throughadditional homogenisation, it can be assumed that the energy required forfurther processing of the WPPO can be significantly reduced.
