13. BIO-TRICKLING FILTER CHEMICAL SCRUBBER
Reactions The odorous gases are converted through the
reaction mediated by microorganisms
The odorous gases are reacted with chemicals
which are dosed in the chemical scrubber unit
Capital cost For equipment size, the capital costs are the
same or lower than the chemical scrubbing
units
The chemical scrubbers are slightly expensive
Contact time Longer contact time of 10-15 sec Shorter contact time, thus smaller footprints
required
Media/
Chemicals
Does not require any chemicals, it uses the
activated sludge which is characterized by
nutrient feed and trickling liquid
From an operational standpoint, the performance
of the scrubbers depends on the chemicals added
Operation Requires minimum 2 weeks to operate, this is
the time period for bacterial growth.
Immediate operation
Volume of
odorous
gases
handled
HIGHER volumes of odorous gases are treated
on time-weight basis
HIGHER volumes of odorous gases treated on
the time-weight basis
Chemical
requirement
No chemicals required expect the nutrients for
growth of microorganisms
Excessive chemicals required
Water
consumption
Comparatively less water usage Consumes lot of water for operation (dilution of
chemicals, etc.)
Operating
costs
Lower operating costs (no chemicals required,
minimum energy costs)
High operating costs (electrical power
requirement for the blower, pumping chemicals,
etc.)
Risk Low risk and minimal accidents due to non-
usage of chemicals
Potential risks due to the chemical usage and
insurance costs.

14. We use Special Catalytical carbon
which can be regenerated &
reused up to 5 times, in special
cases up to 10 times.
Efficiency: 100% of odorous gases
are eliminated.
 They are designed and used for
the removal of vapours and
odours present within the air or
gas flow.
 Main odours to be treated are:
• Hydrogen sulphide
• Indole and skatole
• Methyl mercaptan
• Methylamine
• Ammonia

16. Passive type carbon filters can be used for H2s reduction
on the manhole, air release chambers, small pumping
stations, sewage pits etc., Especially this types used for
remote application, where this no electricity available.
The process is basically same like activated carbon filter
with fan, but in this case no fan, the system directly
connected to the source by using flange or duct fixing
method. The carbon adsorbs the pollutants or odour
allowing into the chamber and vented to the atmosphere.
The system contains, vessel,
grating, catalytic type re-
generable carbon, H2s sampling
port, re-generation valve with
sprinklers, exhaust duct with
weather hood.

17. DIRECT CONNECTION TO THE PIT

18.  Uses
• Deodorization
• Exhaust air purification
(Customized Solutions)
 Possible Constructions
• Areal filters
• Round filters
• Multistage filters
• Coated sea container filters
• Compact bio-filter units
• Covered filters for targeted air routing
• Mobile bio-filter units

20. Prevents chlorine
emissions in case of
accidents.
Prevents leakage from
storage tanks, drums,
chlorine bottles etc.
This unit is activated
automatically by the

31.  MARTIN Membrane Systems transforms sewage to clear and high quality water.
The small footprint of the treatment technology enables the systems to be
integrated in natural, picturesque surroundings and to treat wastewater for irrigation
use.
 MARTIN Membrane System has the core technology inside the MBR which
consists of polypropylene plates with a polymeric membrane on each side. The
membrane is welded on rigid frame. The module reduces virus and bacteria by
99.99%. Filter plates are continuously aerated through bubble diffusers to keep
them clean. The membranes don’t need regular chemical cleaning except one or
two maintenance clearings per year.
 MARTIN Membrane Systems is developing compact package systems for MBR
plants so that up to 1000 m / day can be filtered in one 40-foot ISO container. The
inside tanks are made of stainless steel sheets.
