the use of the natural resource water are boosting the demand for profitable, low-cost

and highly efficient sewerage / waste water treatment systems. Copying nature�s

fascinating capabilities as perfectly as possible and harnessing them for our technical

applications is the source of innovative renewal processes. Nature shows us in an

exemplary manner that organic matter contained in water can be converted biologically

into energy-rich and utilizable.

EEC ME shall provide you an efficient, cost effective, time saving solution for any water

needs, especially the waste and sewage treatment systems. AMB BIOMEDIA ensures

that the system footprint is five times smaller and ten times faster than regular treatment

plants.

DESIGN BASIS

The basic design and the processes use stichomythic factors to alter the concentrations

of the materials involved. As a result of the high level of process linkage, a material can

be of decisive importance to several processes in the model. Should an alteration in the

concentration of this material occur due to one process, and then the processing speed

of another will be influenced, which in turn, has consequences for the entire system.

We have assumed wastewater fully domestic in character from residential application

and that metal contents documented in the consent for discharge would not be present

in any higher amount in the influent and therefore will not present in the effluent. Based

on this assumption we have not allowed for any removal of inorganic material and metals

from the wastewater. We have also assumed the 2*250 m3/day in the residential area

and have allowed a flow of 200 liter per person per day and BOD of � 300 mg/liter in the

influent.

PROCESS DESCRIPTION

The treatment of the sewage water designed for this system can be broken down into

following phases.

Treatment scheme They are;

A. Inlet screening includes manual Bar screen

B. Pre clarification (Buffer or feed / sludge)

C. Mechanical � Biological Sewage Treatment plant � MBBR

a. Bio � reactor - 2 nos

b. Settling / Clarifier - 1 nos

D. Post Treatment includes Chlorination System

E. Irrigation Pumps.

A. BUFFER SYSTEM This will be a construction of three chambers forming the Buffer & Pump well system.

The wastewater will first pass though the Barscreen chamber before it enters into

equalization tank; this separates all solids above 10 MM like, plastics, sanitary pads,

bags etc.

Buffer tank have been aerated continuously with the help of coarse bubble diffusers in

order to keep the particles in suspension. It also helps to avoid wastewater turning

septic. Buffer chamber will avoid any excess oil entering into the pump well chamber

which in turns affects the treatment process.

Note: Buffer tank is continuously aerated, so if you can add the septic sewerage into it, it

will take care of initial polishing and avoid any bad smell so that it won�t have any

negative affect when it enters the Bioreactor. This is achieved by the aeration, the

dilution with sludge that has not turned septic and the time taken by this sewage to enter

into the MBBR plant.

14

B. BIOLOGICAL TREATMENT SYSTEM The treatment plant will take suction from the pump well by its own feed pump. The

pump is level controlled and has a capacity, which is 2 times the average daily flow. The

plant has therefore intermittent working mode in terms of hydraulic flow, while the air

blower supplying air to the bioreactor is continuously running.

The biodegradation reactor comes in three stages. The bioreactors degrade the

dissolved organic matter by oxidation into carbon di oxide, which escapes to the air, and

also a biomass, which acts as an activated sludge. A suspended, free-floating bio film

carrier provides a large protected surface as host for the bacteria and simultaneously

active bio sludge accumulates inside the reactors.

The biodegraded water flows into a clarification chamber where the suspended solids

settle by gravity. The water is directed through a skim well to a Tube settler system,

which provides the final clarification of the effluent. An addition of polymer to the

sedimentation may enhance the cleaning/ settling efficiency if it is required.

C. SLUDGE SEPERATION SYSTEM

The sludge pump will be activated for approximately 5 minutes for every 1 hrs of

operation with suction from the clarification stage. The pump causes the discharge of the

sludge through a hydrocyclone, which separates volatile and non volatile solids with an

overflow back to the bioreactor, while the underflow is discharged to the Equalization

tank. Feed pump will stop whenever sludge pump is working. When necessary, the

sludge is emptied by a vacuum truck and hauled away for disposal.

6. System Operation

SYSTEM OPERATION

Moving Bed Process Technology Using AMB Bio Media. Description of the moving bed process

The basic principal of the moving bed process is the growth of the biomass on plastic

supports that move in the biological reactor via agitation generated by aeration systems

(aerobic reactors) or by mechanical systems (in anoxic or anaerobic reactors). The

supports are made from plastic with a density close to 1 g/cm3 letting them move easily

in the reactor even when the capacity reaches 70%.

The moving bed processes come from the current trend in wastewater treatment, from

the use of systems that offer an increased specific surface in the reactor for the growth

of the biomass, achieving significant reductions in the biological reactor volume.

Initially fixed bed systems were used, however it was discovered that this type

of process show a series of operational inconveniences such as the blocking of the bed

because of the excessive growth of the biomass, this makes periodical cleaning

obligatory. These drawbacks have caused the need for the creation of simple biofilm

processes that eliminate them and that ease their operation; these are the moving bed

processes.

17

This type of process can be applied both to treatment plants for the biodegradation of

organic material as well as for installations with nutrient elimination, in urban and

industrial wastewaters. Another application is the use of this technology in the redesign

of current activated sludge processes, which only treat organic material, to expand them

and include simple nitrogen elimination without the need to construct new biological

reactors.

With respect to the aeration system is via a grid of perforated stainless steel tubes that

avoid problems of efficiency loss, diffuser replacement, etc.

All the wastewater is collected in a 3 chamber Equalization tank. This tank acts as a

balancing reservoir, keep the wastewater in suspension and bar screen used to

separate solids, paper and other waste to be received with the wastewater. The last

chamber of this tank is fitted with a level control system, which starts or stops the

system feed pump. The feed pump takes suction from the last and discharges in to the

first chamber of the High-Speed Bio Tec.

The first and the second chamber of the High-Speed BioTech are filled with AMB Bio

media and water. The last chamber, which is a Tube settler, is filled with water only.

Before starting pumping of wastewater, the system blower starts. The blower forces air

through the manifolds into the first 2 chambers of the bio system and the equalization

chamber.

The influent wastewater enters the first chamber and comes in constant with the AMB

Bio Media and air Large Surface area provided by the AMB Bio Media helps the

bacteria to form large colonies on the AMB Bio Media. Slow circular motion of the

media is caused by the airflow. Each element of the media slowly moves in a circular

18

motion from the surface to the bottom and then upward again. During this movement, it

is in constant with the injected air, slowly a bio film develops over each element, which

disintegrates the biomass present in the effluent.

From the first chamber the effluent flow to the second chamber through the perforated

partition at the top. The same treatment is repeated in this chamber and the remaining

biomass from the first chamber gets fully digested here, effluent at this stage will go to

the 3rd Biodegradation chamber. The treated water then enters the third chamber at the

top.

A baffle plate guides the water entering the third chamber downwards. Then enters the

tube settler from the bottom. The settler provides a large surface area for the

suspended particles to settle down on its surface and the same area guided towards

the bottom. Clean water is let out of the system from the outlet provided at the top of

the third chamber.

When the level of the influent drops in the collection tank the feed pump gets tipped.

Simultaneously the sludge pump is started. The sludge pump draws sludge from the

bottom of the 3 chambers and discharges it into a Hydro-cyclone separates our heavier

sediments from the sludge, which settles in the collection tube mounted at the bottom of

the hydro-cyclone. Clarified water is discharged back into the first chamber of the

bioreactor. The sludge pump operates for pre-set time and is stopped automatically.

19

The solid sludge accumulated in the sludge collection tube is discharge out periodically.

This sludge can be used as manure or for land farming.

High-Speed Bio System should not compare with regular job systems (activated sludge)

as we implemented a leading technology known as �Assisting Moving Bed� or AMB Bio

Media. These systems are designed to handle sewer (black and Grey water) and most

biological wastewater from industrial application.

The AMB Bio Media represents 850 sqm / cum active area once submerged inside the

bio chambers. Activated sludge process and other bio film systems have often proven to

the unstable and difficult to control. By implementing the AMB Bio Media, your benefits

are numerous including reliable and compact bioreactors. The systems are self-

cleaning, non-clogging, can handle server BOD loading, pH variations, and colder

temperatures than regular systems, all this without loss of bioactivity. No sludge return

as in activated sludge system and our systems require minimum service and almost no

attention.

22

8. Installation & Start up

23

INSTALLATION OF HIGH SPEED BIO-TECH REACTOR The High Speed BIOTECH Bio reactor containers require properly leveled ground,

preferably concrete slab with drain facility or properly graveled. The High Speed

BIOTECH reactor must be carefully water leveled before commissioning and checked for

deviation afterwards. Otherwise national safety regulation must be adhered to. A

wastewater pond or buffer tank should be provided upstream of the plant. The pond

should be sized as to level out daily variation in hydraulic load and is to be arranged for

returns of reject water from the plant.

Downstream sludge receiving tank or pond must be provided, the daily produced sludge

and the haul away regularity determine the size of which. Local regulations with respect

to handling and disposal of sludge will determine any further treatment of the sludge.

WARNING

A qualified electrician in accordance with pertinent codes and regulations must perform

electrical installation and connection to the main power source. Turn off facility power

before making any electrical connections. System must be grounded in accordance with

applicable electrical codes.

24

THE AMB-BIOMEDIUM

The AMB bio film mediums are a proprietary bio medium. The Bio medium is produced

of plastic material, which has long lifetime in water. Renewal of the Bio medium during a

treatment plant's regular lifetime should normally not be required.

The bio film carrier elements are extruded tube cuttings with an internal cross and have

25 external low fins. Nominal measurements are Diameter 1/2�, Length 3/8�. The surface

to volume ratio is approx. 850 m² per m3 of Bio medium in bulk.

25

BIOMEDIUM FILLING PROCEDURES (Only applicable for media delivered in bags and separate from system.)

Preparations

Before filling-up and start-up the following preparations to be done:

1. Check that the air holes in the Spurger pipes are facing downwards. If not, drill ½

inch drain holes in each end of the spurges.

2. Check that the bulkhead strainers are positioned correctly and sufficiently secured

3. Check that there are no openings outside the strainers that the biomedia can

penetrate and also no passage for biomedia above the bulkheads where biomedia

can be carried over by eventual foaming. Any gaps to be less than ½�.

4. Start the air blower(s) against open-air valves, and throttle gradually. Listen for

unexpected noises from motor and housing. Run finally the blower(s) against closed

valves for a short time and note the discharge pressure. The discharge pressure

should be not less than 1.5 times the operating water head.

5. Fill the bio reactors with ½ of water, run the air blower from zero to low capacity and

check that the air diffusers are delivering equal and uniformly distributed amount of

air from each Spurger.

6. Start and run the sludge pump in recirculation mode, with successive suction from all

drain valves. Check that the flow is equal from each drain. Checks that the drain

suctions in the bioreactor tanks are enclosed in strainers to prevent biomedia from

entering the pump suction.

7. Start the feed pump with closed discharge valve and note the pump pressure. Open

the discharge valves fully and note full flow and discharge pressure.

8. Start the chemical pumps on water and check capacity.

26

Charging of biomedia

New Bio medium will repels water and must go through a wetting procedure before it will

properly mix in water:

1. Add wastewater to until overflow to the settling tank. Start up the blower(s) and

aerate moderately with ¼ to ½ of normal capacity.

2. Fill biomedia until the bulkhead screens are covered. Aerate continuously during the

filling.

3. Top up with remaining biomedia as space allows. If actual filling degree in the

reactors is 50% or less, then the whole amount of biomedia can be filled in one

charge.

4. Continue aeration until good mixing is obtained, meaning visible movement of

biomedia in the surface.

5. Charge more wastewater while recirculating from the settling tank. When the settling

tank is filled, increase aeration as the water level is increasing in all tanks. Aerate

moderately, just enough to have the media circulating in the reactors.

NOTE

Good mixing is normally obtained after 2 - 3 days on usual municipal wastewater. In the

beginning there will be an almost immobile blanket of biomedia on the surface, while

there will be a good mixing below this blanket and down to the bottom.

27

START UP PROCEDURES

When the media wetting procedure is completed, the reactors are ready for start

up

Municipal wastewater will contain sufficient degrading type bacteria to develop a healthy

bioculture in the reactors without being specifically seeded. Hence, during wetting, the

bioculture will already have started to grow. This can be observed visually by a slight

change in turbidity and pH, usually 1-2 days after completion of wetting.

1. Run the plant on recirculation for 1 or 2 days after wetting. Use the feed pump

instead of the sludge pump. Note the pH and observe any changes. The pH will

first go down during the acidic stage, and then up again as the degradation is

being completed.

2. When the pH is on way back to its initial value, add more wastewater. Change to

recirculation with the sludge pump and shift feed pump suction to the feed tank.

Add a volume corresponding to approx. 1/3 of the total volume.

3. Changes back to recirculation with the feed pump and observe pH again. Repeat

above procedures, and observe the time between each charging.

4. When the time between charging is decreasing, the plant is ready for continuous

operation.

28

BIOFILM GENERATION Time for generation of a bio film on the carrier elements will vary depending on type of

wastewater and the temperature:

Municipal wastewater 3 - 4 week

Food industry 1 - 2 weeks

Paper/pulp industry 3 - 4 days

As time goes by, the bio film will develop and become more efficient and robust. It will

reach its maximum capacity after one year of normal operation.

FOAM CONTROL

During start-up of bioreactors, when establishing bio film on the plastic elements,

foaming may occur. Also greater load variations in fully developed reactors may result in

foaming.

Foaming is caused by surface tensions in the wastewater. Reducing aeration and waste

charging reduces foaming during start up. Foaming in a started reactor is reduced by

combined recirculation and feeding. Foaming in a correctly dimensioned bioreactor,

running on municipal wastewater should normally not occur. However, the wastewater

may contain substances, which make foaming unavoidable.

Sustained foaming during operation may be controlled either by spraying or by chemical

injection. Any available antifoam agent will normally do.

29

SHUT-DOWN AND RESTART

If it becomes necessary to stop the load on the bioreactors for a shorter period, for

instance one-week, all reactors should be moderately aerated to keep aerobic biomedia

condition.

If it becomes necessary to stop the load on the bioreactors for a longer period, it is

recommended to aerate the reactors the first week after the stop, and to restart aeration

2 days before the reactors are re-loaded with organic matter.

Before wastewater again can be pumped to the biological stage, it is important that all

the biomedia is in good suspension in all bioreactors first.

NOTE

Always remember first to stop and start the aeration before stop and start the water

flow.
