Products
Factory not connected to City main sewer, as it is not on zoned industrial park
Currently the 224 Cu. Meters of waste water produced per day is disposed on dug out ponds.
Slurry removal from sedimentation tanks cumbersome.
As production ground gets choked with the water this method of disposal is not sustainable.
Hence the need for a proper waste water disposal system.
Waste Water challenges
Waste Water Parameters:S/n Parameters DESIRED EXISTING
1) Flow in M3/Day 250 224
2) pH 6.8– 7.9 4.5
3) COD in mg/ltr 1875-2000 7,500
4) BOD in mg/ltr 200-250 2,000-2,500
5) TSS in mg/ltr Min. 100 344
Present System - Collection Tanks:
Sedimentation Ponds:
BIL approached the University of Dar es Salaam to find solution to the wastewater problems in 2009
This was because we heard that they have been working on waste water treatment systems especially constructed wetlands
UDSM suggested energy generation combined with polishing in a constructed wetland
BIL and UDSM applied for Bio-innovate funding
