First and foremost, thank you Mr Ting for providing us with the blender!! This blender works as a substitute for homogenizer, which is way beyond budget:
Chocolate Powder + Blender = Chocolate Ice Blended

Yup, Mr Ting, here's our token of gratitude; Bubble Tea!
Mr Kon... You wait! Good food is definitely worth the wait...
On on serious note, the was how the vacuum truck loaded the waste:
2 weeks and rusting occurs, we'll be getting some silver spray paint:
Mr Kon, look at the PI. After 1 week+, gas output is still 0. The failure was expected as I told you earlier that the concentration was way too low; we can't do a direct loading from PUB. We will be manually diluting the waste. Please get the next batch to design a method to control the loading sludge concentration to be between 6-12% (optimum standards).
Something I planned for 3 hours, and ended up we had insufficient chemicals again. On a bright note, the sulphate concentration exceeded the colorimeter measurement range (> 80mg/L); this proved that our hypothesis on the human diet and high H2S output is on the right track. We will be approaching Ms Yang on the photospectrometer usage, which provides a greater measurement range.
The manual loading process:
Now you know why I insisted on getting a 50 cm stand for Brenda
(see below: she's short)...
The primitive manual agitation for 3rd world countries:
Note: Take extra caution to decommission the anaerobic stage isolation valve before agitating the waste. You risk pumping the waste to the next drum.
This is when "Operate" in CDIO comes in. During the design stage, we did not foresee that the pressure in the anaerobic stage due to agitation would cause the sludge in the sight glass to be transferred over to the next drum.
Hence, we surmounted this issue by going back to "designing" the operation procedure (by decommissioning the isolation valve before every agitation).
