Triple Deodorization System for Compost Odor Control

In organic waste treatment and livestock and poultry manure fermentation scenarios, odor control is the key challenge. Ammonia, hydrogen sulfide, methyl mercaptan and other gases are highly irritating, affecting environmental compliance, resident satisfaction and project sustainability.

Bolong Group independently developed “ammonia washing + activated carbon adsorption + microbial deodorization” trinity deodorization system, combined with the cooling tower and circulating water system to optimize the environment, the comprehensive deodorization efficiency of more than 90%, and Bolong independently developed high-temperature aerobic fermentation tanks used in conjunction with the end of the farm odor prevention and control to achieve twice the effect of half the effort.

1.Ammonia washing – to solve the irritating gas from the source

In the composting process of livestock manure and organic waste, ammonia (NH₃) is one of the most common and unpleasant gases. Bolong deodorization system cleverly utilizes the physical property that ammonia is easily soluble in water, and by setting up a multi-stage water washing device, the ammonia gas reacts with water to generate colorless and stable ammonium hydroxide (NH₄OH).

This process not only significantly reduces the concentration of ammonia in the air, but also effectively controls the risk of gas diffusion in the plant. In addition, the resulting liquid can be safely discharged or reused after treatment, realizing the environmental goal of “no waste by-production”.

2.Activated carbon adsorption – efficiently capturing sulfur-containing odor gases

Compared with ammonia, hydrogen sulfide (H₂S) and methyl mercaptan (CH₃SH) are the main culprits of malodor, which have strong rotten smell and low olfactory threshold, and are very likely to cause complaints from the surrounding environment.

Bolong deodorization system is equipped with a highly efficient industrial grade activated carbon adsorption layer after the water washing spray tower, using its rich pore structure and strong adsorption capacity, it can quickly capture these trace but extremely smelly gas molecules and lock them firmly.

The technology does not involve chemical reaction process, stable operation, and before saturation without frequent replacement, low maintenance costs, is a reliable deodorization system in the “second line of defense”.

3.Microbial deodorization – from the essence of “eat” odor

The real embodiment of technological leadership, is the integration of microbial deodorization technology on the basis of traditional deodorization. Through scientific screening, domestication and fixation of functional microorganisms inside the deodorizing device, the system can realize the biological transformation of sulfur-containing gas.

Through their own metabolism, these microorganisms oxidize the sulfur element in hydrogen sulfide and methyl mercaptan into odorless sulfate or sulfur substitute, which is a natural process without by-products and pollution, and truly realizes green deodorization and source treatment.

In addition, the technology can run for a long time and has the ability of “self-renewal”, under reasonable temperature and humidity conditions, the activity of the bacteria can last for months or even years.

4.The cooling tower + circulating water system: the hero behind the scenes to ensure the stability of the system operation

In order to ensure the activity of microbial flora in high temperature environment, Bolong system especially introduces cooling tower system, which controls the temperature of circulating water below 35℃ to create the best living conditions for microorganisms.

At the same time, the closed circuit water circulation design significantly reduces water consumption, compared with the traditional open circuit water washing system, the water saving efficiency is increased by more than 40%, which saves energy and reduces emissions for the project operation.

This system not only improves the deodorization efficiency, but also ensures the long-term stable operation of the whole fermentation system, which is an important guarantee for the synergistic optimization of high-temperature fermentation and odor control.
