Humidification Solutions for Dust and Odour Reduction

Find your Condair expert

Benefits

Humidification systems provide an effective means of meeting required limits, improving process flows and safeguarding the health of employees in many industries that produce significant dust and/or odour emissions.

Dust suppression

Adequate humidity cleans the air of dust faster, reducing the risk of fine dust getting into the respiratory tract.

Odour containment

In addition to binding dust particles with air humidification, odour particles will be suppressed as well.

Observing limit values

Dust is swept up into the air as particle matter in waste incinerator plants, quarries, sorting and shredder plants, which is then carried into the ambient air as airborne dust.

Dust suppression in the wood working industry

Woodworking facilities generate dust both from the nature of the material and from the industrial processes involved. Cutting and sawing with table saws, band saws, and circular saws produce chips, fine dust, and micro-particles as wood fibres are severed. Sanding and finishing, whether carried out manually or by machine, generate large amounts of fine, airborne dust. Planing, routing, and milling use high-speed cutting tools that fragment the wood surface and release fine particulate matter. Drilling and shaping create a mixture of chips and fine dust, while material handling such as moving, stacking, and transferring boards or panels releases accumulated dust and loose fibres. Dry wood conditions, where the moisture content is low, increase brittleness and fibre breakage and therefore generate more dust. In addition, machine wear, such as blunt blades, worn sanding belts, or ageing machinery, can produce more fragmented material.

Humidification systems using fine spray nozzles effectively suppress airborne dust in woodworking environments. By increasing relative humidity, dust particles become heavier and settle more quickly, improving air quality, machine performance, and worker safety.

Dust suppression in the textile industry

Dust in textile facilities is generated by a combination of material properties and mechanical processes. Fibre shedding occurs as natural fibres such as cotton, wool, and linen naturally release small fragments during opening, carding, and spinning. Mechanical abrasion from high-speed machinery that rubs, stretches, and twists fibres breaks off micro-particles. Cutting and finishing processes, including cutting, brushing, sanding, and finishing fabrics, create fine lint and dust. Handling and transport activities, such as moving bales, rolls, and garments, release accumulated lint and debris. Low humidity increases static electricity, which both attracts and releases dust as materials separate. In addition, worn machine components, including brushes, belts, and moving parts, can contribute further particles as they degrade.

Humidification with fine spray nozzles helps suppress airborne fibres and dust in textile production. The added moisture binds loose particles, improving air quality, reducing static, and supporting smoother processing.

Dust and odour suppression in waste disposal facilities

Dust and odour suppression in waste disposal facilities: Spray-nozzle systems effectively suppress dust and neutralise odours in waste disposal facilities. Fine mist binds airborne particles and reduces smell dispersion, improving air quality and working conditions. In addition to benefits inside the facility, effective dust and odour control also positively impacts villages located nearby. By significantly reducing the spread of airborne contaminants and unpleasant smells beyond the site boundaries, these systems help protect local residents’ quality of life. Cleaner surrounding air supports public health, minimises nuisance complaints, and contributes to a more harmonious coexistence between waste management operations and neighbouring communities.
