About AICR (Advanced Immobilized Cell Reactor) Technology

Developed by Govt’s Environment Technology Research Lab Fluidized/ Fixed bed of unique, activated carbon catalyst Bacteria immobilized in pores of carbon matrix Dead bacteria replaced with new ones in the pores Integrates biological & chemical oxidation in a single reactor Counter-current liquid and air streams allow simultaneous

oxidation and desorption Organics oxidized by compressed air from bottom Variations of implementation based on Client specs

AICR Reactor

• Consists of tall column packed with activated carbon

• Activated Carbon immobilized with chemo autotrophs

• Oxygen is sent through compressed air

• Activated Carbon maintains its activity throughout.

Salient Features of AICR Technology

• Will conform to any rigorous specs; even fit for human touch • Cost-effective, incl Investment, Operation & Maintenance

• No consumption of chemicals (except for Industrial Effluents)

• Green technology, with minimal power consumption

• Ease of operation

• Is Modular and scalable

• No degradation in performance, even over years

• Technology Guaranteed from Govt of India

Key Benefits of AICR Technology

(i) Minimizes Investment, Capex and Opex

(ii) No odour, mosquitoes & insects

(iii) Saves > 95% space, for commercial/ agricultural use

(iv) Sludge fully digested; no need for handling

(v) Modern technology; investment good for long term

(vi) Depending on the purpose of treated water, treatment

process can be decided.

Applications of AICR Technology

Biological Treatment: Domestic Sewage Treatment (Municipalities,

Residential Complexes, Oil Rigs) Commercial Sewage Treatment (Restaurants, Hotels,

Resorts, Office Complexes, Hospitals, etc.) Industrial Bio-Effluent Treatment (Food Processing

Plants like Cassava, Palm Oil)

Biological-cum-Chemical Treatment:

Industrial Effluent Treatment (Chemical Process Water Like Tannery, Car Wash, Textile Effluent, etc.)

Small Space Requirement (Incl. All Tanks & Unit Operations)

Many Times, Space Saved wrt Other Technologies Can Pay For STP 30% Area Can Be Saved As Some Tanks Under Ground More Area Can Be Saved If Some Units Are Tiered Space Savings Can Also Result In Power Saving (Just 1 Pump) Complete Plant Can Be In Basement New Materials of Construction (like Ferro-cement and ZincAlume) for

pre-fab lower cost tanks, speed up execution

A few Important Thought-provoking Questions for Westside

One Centralized STP Or Multiple De-Centralized STPs?

If De-Centralized STPs, how many and where?

Solutions from multiple vendors for Different STPs, Or Single solution from a single vendor for All STPs?

Sludge Generation, Transportation, Treatment & Disposal, Or complete digestion, avoiding the costs?

Is Maximising Biogas Generation & Use Viable?

A few Important Thought-provoking Questions for Westside ... (Contd)

Secondary Treatment, or also Tertiary Treatment? To what specifications?

Regulations the World Over DON'T OVER-SPECIFY. Treatment Based on End Application of Treated Water.

Decide End Application, Find out Applicable Local Laws, & Treat To Required Levels. No More, No less.

For Discharge to Sea, BOD < 100, COD < 250 is Normally Adequate. Why Over-Treat & Discharge To Sea If Regulators Don’t Stipulate High Standards?


Even For Re-use to Gardening/ Landscape Irrigation, BOD < 30, COD < 100 is adequate.

Even For Human Handling Like Car Wash, Toilet Flush etc, BOD < 10, COD < 25 may Be Justified.

For Discharge to Live River, BOD < 3, COD < 10 may be Needed.

Cost Difference Between the 4 Applications are Normally High, like 1 : 1.5 : 2 : 2.5


Merely Mentioning Secondary Treatment, or also Tertiary Treatment Is Inadequate Specification.

Different Processes & Designs Of Secondary Treatment Can Yield Entirely Different Treated Water Qualities.

As Wide Results As COD: 250 To COD: 10 Are Possible With Secondary Treatment

So, Necessary to Specify BOD, COD, TSS Of Treated Water

Likely Cost Range of Entire Project

If Treated Water is To Be Fully discharged to Sea, Project Cost of 124 MLD Could Be < 200 Million Canadian Dollars

Sludge Digestion/ Treatment Cost Inclusive

Cost of Pipelines for Discharge, If Required, Extra

System Evaluation Test

Proof Of Concept – Demonstrated in a small scale

Usual Practice in such large projects.

A well known Example of such test is by Singapore Land transport Authority

1 MLD Pilot Plant as Proof Of Concept From Shortlist?

Split Order Among Successful Vendors?

Suggestions for RFP Specifications

Minimum Specifications may be as below:

Volume of Sewage: nnn MLD

Parameter Sewage Treated Water BOD aaa xxx COD bbb yyy TSS ccc zzz

All values in mg/l (or ppm) Parameter Sewage Treated Water

BOD aaa xxx COD bbb yyy TSS ccc zzz

Suggestions for RFP Specifications (contd...)

To Provide STP capacity only for the next 2 years, and not 20 or 25 years, scaling up whenever needed

Larger STPs operating at lower loads operate at their low efficiency zones, increasing Capex and Opex

Capacity increases can be as population increases, say once in 2 years or so, with smaller modules


May consider Separating pipeline laying contract,

both primary and secondary sewerage,

and leading the treated water to the outfalls,

NOT include in this RFP,

as vendors who handle STPs and Pipelines are different


May consider awarding the Centralized STP Contracts to multiple vendors (minimum 3),

avoiding time over-runs,

and not putting all eggs in one basket.

Capacity requirement is large enough to justify this


If organic sludge is generated,

its cost of handling & treatment

and space requirement to be mentioned by the Vendor,

along with value of revenue generating potential, if any

If biogas is generated,

its cost of handling & utilisation

and space requirement to be mentioned by the Vendor,

along with value of revenue generating potential, if any


If Capex is not the only factor in evaluating Offers,

May consider stating the process of evaluation of Offers,

Vendors can try to make Proposals accordingly, enhancing their chances as far as possible.
