Odour Control Management in Industries

From food processing industries and landfills waste to sewage treatment plants and chemical processing units, odour emanation is potent in all forms. Odours produced by a variety of organizations is an ongoing process. That’s why the constant pressure on facilities to keep the odour pollution at bay, is on rising.

What practices one should follow to control Industrial odour?

While many industries work towards the former issues, they often overlook the problem that nasty and stinky odorants create. The pungent smell coming out from the various units is not only a cause of health concerns but also reduces the overall productivity of the employees working there.

Odour management refers to an instrument statement of guidelines or manual of instructions for industries and employees. There are mixed procedures to be followed by both on daily basis to control fugitive emissions contributed by Industries.

Amplifying some of the best practices on odour management.

1. MONITOR & ANALYSIS OF INDUSTRIAL ODOUR

Track the odour — It begins by monitoring the odour and environment. Try to observe the source of the odour, causes of its emission and how large it has affected the facility. Having a well-prepared monitoring plan by your side will help you to eliminate odours more quickly.

Major sources of industrial odour emissions are wastewater, sewage treatment plants, solid waste management, pharmaceutical manufacturing, food processing, chemicals and oil processing units.

Analysation of odour — It is important to run an analysis to recognize the nature of the odour, factors through which it has originated at the industrial unit, the level of concentration of odorous compounds, its emission and discharge frequency.

A major pragmatic way of analysing odours is odour sampling.

2. IDENTIFY ODOUR CONTROL REQUIREMENTS

It is easier to locate primary and advanced odour control requirements, as now that you know enough about odorants, their nature, therefore identification of treatments and technologies becomes simpler. It varies from case to case, facility to facility and cost to cost.

Comprehension of odour control requirements forms a constructive decision-making process. Evaluate two to three products prior to the decision. Trials could help you in determining a product requirement, its use and costs, much effectively.
Some leading odour control units ‘manufacturers in India will help you to skate through odour comprehension and solutions.

Major odour control solutions include odour control units, odour masking.

3. IMPLEMENT THE RIGHT SOLUTIONS

Deployment of odour control solutions in India is a prime step. It is one of the important practices in the realm of odour management. Once, the odour monitoring plan is initiated, analysation of odour samplings is thoroughly carried out, odour control technology can be installed at the facility on the basis of odour control requirements.

Odour problems can be treated through adsorption, oxidisation and scrubbing.

Adsorption Method: Adsorption is the cohesion of ions/molecules, gas, liquid, or dissolved material to the surface of a solid. This is entirely a chemical process and therefore is called the chemical adsorption method. Activated carbon adsorption is one of the proven odour control technologies for various industries.

Biological Oxidization: Biological oxidation is a treatment through which bacteria and other micro-organisms consume depleted and dissolved oxygen and organic substances using the energy released, to convert organic carbon into carbon dioxide.

There are two main categories of biological oxidation methods. One is oxidation via inorganic media such as bio-scrubbers and the other is using organic media bio-filters.

Chemical Scrubbing: It is designed to neutralize odorous gases and remove them. When the process is done chemically, it is also called chemical absorption. Chemicals to scrub are chosen based on the gases to be treated.

There could be lot more treatments to abate industrial odour control problems. But they are widely used in the realm of odour control solutions. Companies, as per the odour type, size of the facility, cost of technology, may install single staged technology or multi-staged technology, having more than one treatment.

Some of the world-class odour control systems in India is offered by AQOZA, which has a wide range of,

How To Remove The Smell From The Sewage Treatment Plant

There are various reasons for determining the bad odour from any sewage mechanism and ascertaining those grounds is one of the most integral steps to control the odour. Seemingly, anaerobic decomposition of organic compounds generates a foul odour at the sewage treatment plant and their low solubility in wastewater makes them liberate into the environment causing offensive odour. Understandably, these sewage odours often pollute the entire nearby surroundings and are not meticulous matters that can be tolerated. Although controlling these repellent odours sometimes get a bit challenging, however, few steps can be pursued. Initially, we would recommend discovering the reason behind odour and then trying to look for odour control technologies accessible. Consult an expert If you haven’t treated the plant in recent days or didn’t consult for service, we would suggest speaking to your local service providers.
