Prototype 2 Construction Progress - Piping's Up on 6 October 2010 (Wednesday)

A picture speaks a thousand words; click on image to enlarge.

In summary, the main piping and valve connections are up, less the sight glass as we were short of a 1" x 1/2" Reducer Bushing. The workers used metal and I explained to them that metal can't be used - detrimental to methanogens etc. Hence, I will need to do more purchasing tomorrow. Due to the lack of manpower, me and marcus will work on 2 separate sites:

Kian How - Tuas:

• Buy 1" x 1/2" PLASTIC Reducer Bushing x1
• Buy 1" threaded sch 80 End Cap x3
• Buy 2" threaded sch 80 End Cap x1
• Buy 2" Hose Ring x1
• Drill holes on base - to prevent rain water accumulation
• Supervise construction of bushing for gas sampling port
• Call Ai Ling (Auric) for Detailed Gas-D Sampling Probe Dimensions

Marcus - SVF:

• Meet Vacuum Truck at 10.30am
• Run Orange Digestor
• Draw out a table of data to record (Temp, pH, age of input waste, etc)
• Follow up on Totalizer

Auric Gas Detector Sampling Probe - KH to call Auric for dimensions to construct sampling port:
