Four Water Classes (Quality)(Government Regulation No 82 Year 2001

• Class I : Best Quality designated for raw water for water supply; and include Class II till IV (BOD < 2 mg/L)

• Class II : designated for water sport activities (not a direct contact) and include Class III and IV (BOD <3 mg/L)

• Class III: designated for fishery (aquaculture) and include Class IV (BOD < 6 mg/L)

• Class IV : designated for irrigation (BOD < 12 mg/L)

• For most of the rivers in Indonesia: intended to be Class II.

What has happened can be explained by the following diagram:

Water Risks or Challanges:

In Indonesia

• Decreasing Water Availability and Reliability of Supply.

• Declining Water Quality

• Failure to Meet Basic Water Needs.

21

Opportunities

• At the same time, these risks present possible opportunities for the water industries that produce technologies and provides services for meeting water needs.

• Careful analysis of opportunities and needs may prove valuable to corporations and investors who are seeking to capitalize on smart and effective solutions to water problems.

Example of Collaboration ITB with

Japanese Companies:

- Low Cost Membrane – Asahi Kasei

- MBR – Toray Membrane

-MBR – Industrial Scale

Pilot Study in Bandung

25

Conclusions of the study

• The applicability of submerged membrane filtration without any chemical dosing to the treatment of river water containing high turbidity was investigated.

• The operation of the pilot-scale submerged membrane filtration unit was very stable and can be continued for three months without any irregular membrane cleanings.

• Increase in membrane flux and decrease in frequency of regular maintenance cleaning did not affect the rate of membrane fouling development.

• Owing to its higher membrane flux and less frequent maintenance cleaning, operating expenditure of the membrane based water treatment system was equal or even lower in comparison to the conventional water treatment system based on coagulation, sedimentation, and sand-filtration.

Characteristics of the Produced Water• High TDS

• Fluctuated COD (300 – 4000 mg/l, including data from pilot test)

• High oil and grease

Pilot Test PerformanceOil Content Profile

32

• Oil is totally removed by membrane

• Could be a problem, therefore use DAF in real plant

• Not problem in this test if performs membrane cleaning

Pilot Test PerformanceFouling rate

33

• No fouling detected after daily cleaning

• Fouling in the first 5 days probably were caused of microorganism attachment to membrane surface
