THE CARBON MAkES THE DIFFERENTROMOLD Activ-cArbon

WHAT IS ACTIVATED CARBON?

Activated carbon is a highly porous carbon-based

material which on account of its internal surface

area binds atoms and molecules to this surface by

means of an attractive force (adhesion).

One gram of activated carbon has an internal sur-

face area of 700-1800 m2.

Activated carbon consists of micropores (up to 1

nm), mesopores (1-25 nm) and macropores (abo-

ve 25 nm).

Activated carbon has been mass produced since

the early 20th century.

MODIFIED ACTIV-CARBON

Activated carbon has long been available for use

in removing odors – but Activ-carbon, with its ca-

talytic effects, has only just become available

for use in reducing H2S and odors. The secret lies

in the patented manufacturing process (doping)

that‘s used in the ROMOLD Activ-carbon product.

Modified Activ-carbon begins working immediate-

ly through catalytic reaction without compromi-

sing the adsorptive capacity that comes from the

surface coating (impregnation). This creates a seal

in the micro- and mesopores which is critical for

adsorption and thus significantly reduces the in-

ternal surface area and in turn the adsorptive ca-

pability. The 5 g of internal surface area in the

Activ-carbon is roughly equivalent to size of one

football field. The carbon contained in a

ROMOLD Activ-filter has the internal surface area

of 500 football fields. An Activ-filter for pumping

stations cleans the exhaust of 150,000 m3 of was-

te water per year and eliminates peak values up to

300 ppm H2S. Whether on hot or cold days, damp

or dry. The Activ-filter maintains its effectiveness

over time (day after day). With patented, modified.

Activ-carbon from ROMOLD, the problem of elimi-

nating odors is resolved through catalytic conver-

sion.

THE ADVANTAGES Of THIS SYSTEM ARE:- freely accessible micropores- effective loading with short retention times- water-insoluble “active centres” for sorption catalysis- high pore volume, huge loading capacity

ADSORPTION PERFORMANCE

The Activ-filter is specially designed for

elimination of hydrogen sulfide and ammonia.

but because of the special manufacturing process

of the activated carbon that is used, other

aromatic substances which are typical of waste-

water can be absorbed through adsorption pro-

cesses and odors can thus be largely eliminated.

The adsorption occurs primarily in the micro- and

small mesopores. The size of the pores and the dis-

tribution of the pore size together determine the

adsorption characteristics of individual substances,

independently of their size and chemical proper-

ties.

PHYSICAL ADSORPTION

AND CHEMISORPTION

Non-polar substances (e. g., hydrocarbons) are

adsorbed on the Activ-carbon (=physical

adsorption) very efficiently.

The adsorption performance of polar substances

(e. g., H2S) on activated carbon can be increased

through specific adsorption and surface reactions

(= chemisorption).

WHEN ODORS ARISE

The problem: the population consumes less water,

while the sewer networks are oversized. At the

same time, the quantity of industrial waste waters

is increasing. Sometimes it stinks to high heaven,

and not just on hot days.

The Activ-carbon itself is resistant to moisture and

dryness. At no time is there a risk of clumping or

airtight closure of the chambers (as occurs with

other systems).

ROMOLD Activ-carbon is a product of the BMWi program „Network

Management East (NEMO)“ under the direction of the „Fraunhofer

Institute for Environmental, Safety and Energy Technology UMSICHT“.

It is industrially produced and its effectiveness can be verified through both

practical and computational methods.

ROMOLD Activ-carbon is used in adsorbers (filter

chambers) to eliminate odours in cases of very strong,

bad odours and high air quantities. The filtering

system is put together on a custom-made basis

according to the local circumstances. We recommend

carrying out an H2S measurement in advance to allow

the filter adsorbers to be precisely designed. The

ROMOLD product line includes adsorber sizes: DN 625,

DN 1000 and DN 1250, equipped with:

- filter cartridges CAR-1050 (max. 3 units)

- Activated carbon in loose form with

a bed height of 30-100 cm

POINTS OF POSSIBLE ODOUR PROBLEMS

A) PUMP CHAMBER

In cases of strong, offensive odours, the entire air is suctioned out

of the pump chamber. A fan in the adsorber chamber creates a

slight negative pressure, thus extracting the entire exhaust air via

an activated carbon bed. A filter is put in the pump chamber cover

so that bad odour can be reduced even in the event of a power

failure. The amount of activated carbon is determined according

to the concentsation of H2S and the period of use required.

B) VENTING- AND EXHAUST VALVE CHAMBER

At certain points in a pressure pipe, a venting/exhaust valve might

be required (such as: high points). At such points, exhaust air

polluted greatly with H2S is blown out in the exhaust process. This

exhaust air is cleaned with activated carbon via a filter chamber.

The filter chamber can be equipped with a loose bed or with filter

cartridges.

C) PRESSURE PIPE END CHAMBER

At the end of pressure pipes H2S is outgassed through the

desired turbulence of the waste water, thus reducing the load

in the following gravitational sewer. The exhaust air from these

chambers is suctioned by a fan through a filter chamber, the

purified air thus being discharged into the atmosphere. This filter

chamber can also be used for pressure pipe end chambers with a

rising incline or other chambers with odour problems.
