To address the problem of reducing odors in composting facilities, the first step is how to reduce the concentration of the original odor. First, review fermentation failure by changing the properties of the mixture and improving aeration. If the bad odor cannot be removed even after that, consider installing deodorization equipment. We can propose a system that suits the mixture of raw materials and the facility, so please consult us.

How to Improve Ventilation

Improving ventilation will promote fermentation and increase temperature without heating

Poor ventilation causes fermentation failure, and the main cause is compounded odors due to anaerobic fermentation. If there are many types of malodorous substances, it is difficult and expensive to use deodorization equipment to counteract them, so it is important to promote aerobic fermentation first. It is possible to reduce odors by supplying appropriate oxygen to the compost material through improved ventilation.

How to Introduce Deodorization Equipment

Odor that cannot be removed by fermentation process or ventilation improvement requires addition or review of deodorization equipment

Proper deodorization design is important for deodorization equipment, including the selection of a method according to the conditions of the facility, calculation of the scale, and duct structure and layout. MIRAIE recommends the ‘MIRAIE Biological Deodorizing Equipment’, which offers an excellent balance between deodorization performance and cost.
When malodorous gases such as ammonia and hydrogen sulfide are passed through the porous glass material with countless minute pores, microorganisms settled in the pores quickly decompose and deodorize the malodors. The deodorizing base material does not need to be replaced for more than 10 years and can be replaced in existing facilities.
