Dusty Air Treatment
DESIGN of Air Pollution Control Device
Developing an optimized air pollution control system requires the
consideration of a wide range of engineering, environmental, economic,and
regulatory factors. At SAVECO, we have assisted a wide variety of
industrial, municipal, and research clients with the selection and design of
effective air pollution control systems.

ADSORPTION TOWER Odor & VOCs Removal Device by Activated Carbon
The SAVECO Activated Carbon Adsorbers are well suited for the removal
of VOC’s from high flow air streams and other emission control
applications. Some typical applications for the SAVECO Adsorbers include:
• Industrial plant emissions
• Soil vapor extraction (SVE) remediation system off-gases
• VOC removal from dusty air emissions
• Backup VOC control device for thermal oxidizers.
The frequency of adsorber exchange will depend on operating parameters
that affect carbon loading such as VOC type and concentration, temperature,
relative humidity, superficial gas velocity, carbon type (coconut shell or
coal) and other factors.

Heat Exchanger
The hot flue gasses pass from the incinerator ① to
the gas cooler ② via either an underground canal or
overhead flue duct. The gas cooler ② comprises two
water cooling circuits, and one combustion air pre
heat
section
which
improves
the incinerator
efficiency. The water cooling circuits are connected
to a back cooler ③ which is mounted outdoors. he
cooled gasses then pass through a cyclone separator
④ which removes all but the finest dust particles
from the gas stream. Separated dust leaves via a
cell wheel sluice and falls into the collecting bin ⑤.
The gasses then pass to the ball rotor recycling and
conditioning unit ⑥. A the start of each working day,
a pre determined quantity of fresh adsorbent is
automatically loaded from its storage container ⑦.
The gas stream passing through the ball rotor unit will
be treated by the adsorbent, some of which will be
entrained in the gas stream leaving this section. It
then passes into the SDR/SNCR ⑧, where hazardous
gas plus the entrained adsorbent will be removed.
An automatic system cleans the bags by inflating them
in order to dislodge the accumulated deposits. These
deposits fall to the bottom of the unit ⑨, where the
majority is returned to the ball rotor unit. This
ensures that the adsorbent is recycled until it is fully
used. Any rejected deposits are removed through a
cell wheel and fall into a collection bin ⑩.
The completely clean gasses pass from the bag filter
through the induced draught fan ⑪ to the exhaust
stack.

Emission Characteristics
From Source Materials
Research Objectives
Coating materials are composed of very complex chemical
compounds, these indoor building materials discharge very
much VOCs. We performed the environmental chamber test
to investigate the TVOCs emission characteristics and
emission factor about paints. As the result, we knew that
those of TVOCs emission characteristics are high emissions
at initial time and decreased in course of time. The emission
factor-time profile showed good fit with the results from the
measured and predicted value

Time (hr)
Liquid manure can be successfully composted by our aerobic-liquid composting methods. The liquid composting manure maintained high temperature over the initial reaction period,
about 3 days. The curing compost continued to stay hot for an expended period of time, beyond the typical seven to fifty days. Aerobic composting of liquid manure to produce organic
fertilizer results in a significant reduction in C/N ratio from livestock operations, compared to the raw materials. Most of the reduction in mass (water content, carbon) occurs during the
active aerobic composting phase while organic component in total nitrogen and suspended particulate were increased.
