Hi,
Yes, it is possible to eliminate odors completely from chicken broiler farms,
but it depends on several factors such as the size of the farm, the area of the
farm, odor causing factors in the farm and one’s willingness to comply with the
described odor management plan.
In order to develop effective odor control strategies for chicken broiler
farms, one needs to take systematic approach for odor management, starting with
identifying the sources of the odor, factors that produce them and sources to
eliminate them.
Odor control technologies can be thought of in three different categories,
those that reduce the generation of odors, those that decrease the emission of
odors, and those that increase dilution of odors. There are around 24
technologies, for odor control.Once the major sources of odors are identified
in a particular farm, one can start with 2 to 3 technologies out of it and once
it proves effective can start with new one until satisfactory results are
achieved. On the University of Minnesota website a good odor management plan
with the 24 odor control technologies is listed.

Most common approaches taken for odor removal include, proper manure
management, chemical usage, moisture control, installation of aerated systems
etc….There are many options available in the market today for the same. I am
listing a few most popular approaches taken by the people and proven to be
effective.
In chicken houses major odor-causing compound like ammonia, can be eliminated
using Effective Microorganism (EM) products like EM Probiotic and EM Waste
Treatment. Several experiments with EM Probiotic in broiler farm indicated
reduction of ammonia up to 70% in chicken dung. Use of EM Waste Treatment can
eliminate odors and insect pests with in 48 hours.

CBPA is another organic liquid chemical, which is widely used as odor
abatement. According the review for the product from Eco Chem website this
product tend to eliminate all the malodors from the poultry farms to
satisfactory Level. Customer reviews for the product have been listed on the
Eco Chem website.

TrueFog is another simplest and most effective method of removing odors from
manufacturing or industrial waste handling treatment sites and poultry farms.
TrueFog odor control systems provide a safe and economical method of
eliminating a wide range of odor problems. It is easy to install within few
hours and can operate 24 hours a day.

Use of biofilters is also another cost effective way for odor removal by
converting the odorous gases to carbon dioxide and water. One of the cost
effective and easy to use biofilters is a bed of organic material, typically a
bed of mixture of compost and wood chips or shreds. This generally costs in a
range between $100 and $150 per 1000 cfm of air to be treated.
