IV. Technical Design and Criteria

A. Technology Specification for the Biomethanation Plant

Considering that biphasic process of biomethanation is more efficient and the percentage of

methane in the biogas is higher (almost above 65%), it is considered that this process will be

deployed in the biomethanation plant to be constructed.

The Biphasic process will involve – hydrolysis cum acidic phase and methanogenic phase.

The Biphasic process may have two options:

(i) both phases as suspended particulate matter

(ii) first phase as suspended particulate matter and the second phase as UASB

(Upflow Anaerobic Sludge Blanket) after extracting the leachate from the solid

waste through the process of hydrolysis and acidification.

In this case aqueous extract of the solid waste is prepared in the 1st phase reactor, which is then

subjected to pH correction and then fed slowly and steadily into the 2nd

phase reactor (UASB)

using a peristaltic pump or a dosing pump. The hydraulic residence time in the UASB should be

about is about 24 hours.

B. Proposed Process Flow for Operation of Biomethanation Plant

1. Unloading of the segregated MSW on a raised platform. The height of the platform will

be such that unloading from the commonly used door to door collection system can be

conveniently carried out.

2. To ensure presence of only biodegradable matter in the feedstock for the biogas plant, a

sorting conveyor is provided. Ideally the conveyor should be 7 meter long with two

persons on either side taking out dedicated items and putting them into dedicated bins.

Non-biodegradable material can be sold or given to the waste sorters.

3. The biodegradable waste is passed through a wet grinder, where coarse grinding (2-3 cm

size) is done along with water.

4. In the first phase reaction (hydrolysis and acidification) the material is kept for 6 days for

optimal conversion (optimal time). Approximately 2 tons of feed material along with 2

m3 effluent from the UASB (including wash water from filtration tank T if necessary) is

allowed to ferment for 6 days (optimal time). For facilitating the reactions, either a small

pump is used to re-circulate the liquid or a small stirrer is used to stir occasionally. At

the end of 6 days a slurry pump is used to empty the contents of this tank into a filtration

tank (T). Here the liquid is filtered out from the residual solids using a stainless steel

screen (figure 4).

5. In view of the retention time of 6 days, 6 numbers of similar tanks (D1 – D6) are used.

These tanks are used on subsequent days. When the first tank (D1) is emptied after 6

days, it is again filled up on the next day. This sequence goes on.

6. The filtrate from tank T is piped into a buffer tank (E) fitted with pH probe and pH

correction system. A stirrer is fitted in the buffer tank for mixing the contents which has

high BOD and COD.

7. The liquid from the buffer tank is put into the UASB column (F) slowly and steadily

using a ‘dosing’ pump. The residence period inside the UASB (Upflow Anaerobic

Sludge Blanket) is 24 hours.

8. The effluent from the UASB (2nd phase reactor) is piped into the first phase reactor (D) to

reduce water consumption and recirculation of nutrients.

9. The biogas is stored inside a floating gas holder. Instead of water, the well of the floating

holder can preferably be filled with the effluent of the UASB. Alternatively a flexible

neoprene balloon can be used.

10. A biogas generator of 30 KVA is used to generate electrical power.

The drawings are provided in Annexure 2 (Figures 1-6).

No.


• All plaster work should be cured for the recommended

period (dependent on weather).

3 PCC (plain

cement concrete)

• The shuttering material for form work, moulds etc. should

have smooth surface (MS, marine plywood or seasoned

timber). Practically, MS is the safest bet. All shuttering

material and moulds need to be cleaned of any previous dry

plaster or concrete.

• Appropriate mix of concrete is of utmost importance even

proportion of water must be according to the recommended

ratio. The coarse aggregates (stone chips) must be of

recommended quality and size grade. Sand must be cleaned

and screened so that uniformity is maintained.

• Appropriate size of vibrator must be used to remove any

gaps, voids, holes etc. This is especially important where

water tightness and air tightness is essential.

• The concrete surface must be finished smooth.

• Curing for the recommended period (as per relevant IS

code) is essential for the concrete to reach its desired

strength and other characteristics.

4 RCC (reinforced

cement concrete)

• All the points mentioned for PCC is relevant for RCC as

well.

• In addition, the steel bars must be of the recommended size

and quality. The bars must be clean and free from rust.

While embedding steel bars in a concrete mass, care should

be taken to maintain the recommended thickness of concrete

cover on either side of the steel bars.

• The surface should be smooth on all sides.

5

Metal works • All metal surfaces must be cleaned and rust removed before

welding.

• Again the surface must be thoroughly cleaned before

applying primer and then paint. Zinc Chromate primer

should be used after cleaning. When the primer coat is

thoroughly dry, the paint coats are applied. Initial paint

coats are lean and thicker coats are subsequently used

Sl.

No.


towards the final coat. Total 3 coats are necessary for

durability.

6 Environmental

and health related

compliance

• All compliances related to the environment and health

should be regarded as mandatory for responsible work

culture.

• All workers need to be trained about safety issues at the site.

Protective gear (helmet, apron with fluorescent markings,

hand gloves, gum boots etc.) must be issued to each worker

and the site supervisor should check that every one use the

safety gear while at the site.

• The first aid box at the site should be regularly inspected to
