How to solve the odours problem

Most industrial processes are characterised by the presence of odours, fumes and dust.

Some of these can be harmful to air and environmental quality.

At this very moment, a national standard related to odorous emissions is being drafted, listing the industrial activities with the greatest odorous impact.

We are used to considering an analytical limit for odour, but the correct approach is to evaluate the odour flux (OER "Odour Emission Rate") and the impact that an emission point may have on nearby receptors using a dispersion model, starting from the emission measurement of the facility and the airflow rate.

Hence the need to find effective and reliable deodorisation, dust abatement and emission solutions in line with innovative green technologies such as multi-stage scrubbers and air treatment units.

TWT Scrubber

The Reliable Solution

A very simple and reliable way to remove water-soluble odorous substances is washing the sucked air with water.

In the past, water-based washing towers or scrubbers were designed in a poorly rigorous manner, thus some units were dimensioned according to the maximum air flowrate that could pass through the tower, with the consequence that sometimes the scrubber was not considered effective.

In reality, this was only caused by incorrect sizing and mismanagement, not by any specificity of the technology.

THE APPROACH OF TECNOIMPIANTI IS TOTALLY DIFFERENT!


Sizing

The different categories and types of polluted air require different approaches and contact times even longer than those recommended by the BAT (Best Available Technologies) reference documents and by the regional guidelines.

Scrubbers manufactured in our workshop are specifically designed for each type of odour (odours from wastes, composting, food production, rendering, mechanical processing or molding).

TECNOIMPIANTI scrubbers have special fillings optimized to maintain low pressure drops even in case of fouling, in order to guarantee an effective washing with water or with chemical products.


Structure

The structure of the abatement scrubbers is made of special polypropylene resistant to UV and to low temperatures or even ATEX PPS-el and can be manufactured with one or more stages in series with different washing solutions in the same tower (multistage scrubber).

TECNOIMPIANTI abatement towers are designed to treat gases with flowrates from 1000 to more than 150,000 m3/h and to assure emissions compliant with the standards set by law.

Furthermore, we can provide filtrating systems with scrubber+biofilter, ammonia stripping or abatement systems and ammonium sulfate production plants.


Why you should choose our plants?

  • Effective reduction of odorous emissions.
  • Flexible plants with the possibility of multistage operation.
  • Special fillings with low pressure drops and high resistance to fouling.
  • Special design of internal parts and supports.
  • Special anticorrosion materials (PP for low temperature, PPS-EL ATEX).
  • Use of control systems of pH and/or conductivity for continuous monitoring and maximum automation of the plant operations for the 4.0 transition.

How can we reduce odours?

The experience gained in multiple sectors allows us to offer reliable solutions for the treatment and reduction of odors in various sectors, both with scrubbers and with integrated systems with activated carbon, biofilters, biopercolators and bioscrubbers:

  • waste treatment
  • composting
  • vent treatment from tanks
  • agri-food productions
  • dairy products
  • cured meat factories
  • fertilizers production
  • centrifuges vents
  • tanker washing plants
