Odor control is the essential process of eliminating harmful and unpleasant smells—especially those caused by gases like hydrogen sulfide (H₂S) and ammonia in sewage, industrial, and residential environments. Aaxis Nano offers advanced, scalable odor control solutions through four key products: SULPHACTUS, a high-efficiency two-stage biotrickling and carbon filter system for heavy-duty STP and industrial use; SULPHUS, a biological biotrickling filter delivering over 99.9% odor removal with low operational cost; ACTUS, a durable, standalone or polishing activated carbon unit ideal for low-odor and VOC removal applications; and ORGUS, a modular biofilter designed for both industrial and home settings with natural coir fiber media. These systems operate using proven technologies like chemical scrubbing, biofiltration, activated carbon, and ozone/UV treatment, tailored to handle airflows ranging from 500 to 200,000+ m³/h. Aaxis Nano also provides eco-safe STP odor control chemicals, remote monitoring, and plug-and-play systems that ensure compliance with CPCB norms and improve environmental and worker safety.

What Is Odor Control and Why Is It Important?

Odor control is the process of eliminating or neutralizing foul smells, especially in areas prone to gas emissions due to waste decomposition. Effective odor control:

• • Enhances air quality and working conditions.

• • Reduces complaints from nearby communities.

• • Ensures compliance with pollution control norms.

• • Extends the life of sewage and treatment infrastructure.

STP Odour Control Chemicals: What Are They?

Aaxis Nano offers environment-safe odour control chemicals used in dosing and misting systems to control STP emissions. These:

• • Target gases like H₂S and ammonia.

• • Are non-corrosive and biodegradable.

• • Work seamlessly with our odor control units.

Odour Control Unit: Working Principle

Each odor control system at Aaxis Nano operates on one or more of the following principles:

Technology	Description
Chemical Scrubbing	Absorbs H₂S and NH₃ using acidic or alkaline solutions.
Activated Carbon Filtration	Captures organic molecules and VOCs.
Biofiltration	Uses microbial colonies to break down pollutants biologically.
UV/Ozone Treatment	Breaks down gases at a molecular level for instant deodorization.
