Biotrickling
Recognizing the need for environmentally friendly, perfectly performing and low-cost air treatment technologies and the limitations associated with conventional biofilters, we have developed an innovative biotrickling technologies. The need for reliable and cost effective technologies is urged by rising concerns about air contaminant emissions (carbon dioxide, NOX, VOC’s, etc.), workforce exposure to organic solvents and public complaints about odours from wastewater treatment plants.

Sulphus - Compact Biotrickling Filter
The Sulphus is a compact biotrickling filter for reliable and highly effective removal of hydrogen sulphide (H2S) and other primary sources of wastewater odours, including ammonia, mercaptans and ...

VOCUS - Emission of Volatile Organic Compounds (VOC) Control System
The Vocus with its innovative biological treatment achieves an entirely new level of performance in VOC Control. The VOCUS has a big advantage for lower solvent emissions above RTO's. The VOCUS is succesfully used for over 10 years now. The VOCUS is a development since 2004 and is based on the biological destruction of the solvents from the waste air stream of the factory. The installation will be placed outside the factory. The air will be led through ...

Chemsorption
Scrubber systems are a diverse group of air pollution control devices which can be used to remove particulates and/or gases from industrial exhaust streams. Traditionally, the term `scrubber` has referred to air pollution control devices which used liquid to `scrub` unwanted pollutants from a gas stream. All chemical scrubbers are designed for a large contact area between the gas and liquid phases. Odour control however requires some dedicated design features.

Model MPX - Cross-Flow Scrubbers
Our cross flow scrubbers feature a number of advantages compared to vertical packed bed towers. Ducting is simpler and the crossflow design makes it convenient to fit the scrubber in a ducting system. In the case of a single stage design, a packed tower may be preferred in view of its convenient combination with a stack. Choice of material is usually plastic, given the chemical additives used in the ...

MPV Scrubber
Pure air solutions offers standardised packed tower scrubbers ranging from 1,000 to over 50,000 m3/h. Water soluble contaminants can easily be removed from an air stream by scrubbing in a packed tower. The counter flow principle ensures high efficiencies for most common pollutants like ammonia, hydrogen fluoride, hydrogen chloride and similar pollutants. Obviously the pollutants must be soluble in water to a certain extent. Slightly soluble gases can ...

OCC Solution
Odorous components can be removed from an air stream by condensing water vapour present in the air stream and subsequent absorption of these odorous components in the condenser. The Odour Condensation Cooling (OCC) system is based on the principle that gaseous components tend to establish equilibrium between its concentrations in the -as phase and water. In the OCC heat exchanger the air is cooled to below the water dew point. As a result a layer of ...

Preconditioning
The operation of a biofilter for odour control can be problematic for three reasons. Firstly, the performance and life span of the system is very much related to temperature and maximum temperature is at 35°C. Secondly, drying out of the organic biofilter can occur if the relative humidity of the incoming air is not close to 100%. Thirdly, excessive dust in the incoming air can cause clogging of the organic biofilter material, which can also occur in the structured packing of a chemical scrubber.

Precon
The Precon is especially designed for conditioning airflows before treatment in a biofilter. Through an adiabatic process polluted air is cooled down (or heated up) to 35°C before entering the biofilter. At the same time the Precon humidifies the air to approx. 99% RH, and removes dust and fat. It is proven that the use of the Precon gives higher odour removal efficiency and a lower pressure drop. It can also be used at existing bio-filters and is ...

Venturi Scrubber
Our Venturi scrubber utilises the kinetic energy of an air stream to accomplish dust collection through the principle of impaction. The contaminated air stream is accelerated through a throat section reaching velocities between 45 and 120 meters per second. Water is introduced ahead of the throat and atomised by the high air velocity. Dust particles collide with and are captured in millions of small droplets. In order to avoid build-up of dust at the ...

Biofiltration
Pure Air Solutions has extensive knowledge and experience in biofiltration. Our engineered biofilters, developed, designed and built since the 1990’s, have provided significant footprint reductions, reliable operations, low running costs and removal efficiencies of 95% and more. Small (> 2.000 m3/h) and very large airflows (> 200.000 m3/h) can be treated. Although for large airflow a large area (footprint) has typically been required, our systems have reduced this footprint to 30% - 50% compared with conventional biofilters.

ORGUS - Concrete Biofilter
Building compact in prefabricated concrete containers enables us to deliver biofilters that achieve outstanding removal efficiencies with less than 50% of the size of conventional biofilters. Our dual stage concrete biofilter achieves removal efficiencies of 95% or more on a smaller footprint and with a lower operational cost compared to any other commercially available odour treatment technology. State-of-the art design, advanced airflow distribution, ...

ORGUS - Model FRP - Biofilter System
Our FRP biofilter has a light weight design and is especially engineered for small airflows or to achieve significant footprint reductions at larger airflows. Because of the light weight design FRP biofilters can be stacked in a frame. Despite its special and light weight design, no concessions have been made when it comes to reliable operation, cost and removal efficiencies. Smart design, perfect airflow distribution, high quality media and efficient ...

Custom Build Biofilter
A custom made biofilter built at your facility. This biofilter is especially suited for large airflows of 80.000 m3/h or more, where total odour solutions are required. It achieves >98% odour removal rate at sites with high intensity ...
