AEC SYSTEMS – YOUR PARTNER FOR SOLUTIONS TO ODOUR AND EMISSIONS PROBLEMS

AEC Systems specialises in the purification of process air produced by various industries. AEC Systems consults, designs, produces, installs and maintains air purification systems. For us, everything revolves around the individual customer and that customer’s problem. We will investigate possible solutions to the air emissions problem in partnership with you, where appropriate by means of testing and measurements on-site. We will then design the optimum system - with a focus on minimising energy consumption and environmental impact as well as reducing emissions.

ABOUT US

Our company is founded on very extensive experience (established in 1994) in designing, producing, supplying and maintaining technologies to reduce air emissions. We strive to design and supply the ideal solution for each customer. In doing so, our primary focus is on the following areas:Significant reduction of emissions of polluting compounds to airUse of sustainable materialsHigh reliability of the systemLow energy consumption Maintenance that is simple and fast to implement

We want to be your reliable partner in every step of the process. Thanks to a thorough analysis of the problem conducted together with you, we are able to recommend the optimum solution for the air emissions problem.

INDUSTRIAL EMISSIONS

The government is increasingly restricting emissions from polluting components via ventilation and/or process air. Odour nuisance is an increasingly frequent problem, one reason being the increasing shortage of space in residential areas. Homes are being built ever closer to industry, increasing the chances of nuisance from odour. The list shown here summarises a number of industries in which the production process involves odour emissions. AEC Systems designs and supplies systems to effectively capture these odour emissions.

WET SCRUBBERS

Odour is made up of a large number of different compounds, most of which dissolve easily in water. Wet scrubbers use water as the transfer medium. The compounds which cause odours dissolve in water in the scrubber and are filtered out of the air in this way. The air is washed using water. In order to limit the use of water, substances are added to the water which increase its capacity to absorb. If the air flow contains dust, it is also possible to make a dust scrubber the first scrubbing stage.

VENTURI SCRUBBERS

A Venturi scrubber uses the kinetic energy of an airflow to achieve dust removal through collisions. The airflow contaminated with dust is accelerated through a narrow section which causes the speed of the airflow to increase from 45 to 120 metres per second. Water is injected before the acceleration occurs and nebulised by the high speed of the airflow. Dust particles collide with and are encapsulated by millions of tiny water droplets. In order to prevent an accumulation of dust on the intake side of the Venturi, a sharp transition is maintained between the dry and wet zones.

Where the Venturi opens out beyond the narrow section, the static pressure is reduced by means of a reduction in the speed of the airflow. The airflow saturated with water changes direction in a bend through which water flows, after which the air enters a cyclone. In this cyclone, the droplets are “hurled” out of the air. Clean, droplet-free air exits the Venturi scrubber via the demister.

BIOFILTERS

A biofilter makes use of biologically active material, the biomass. In most cases, the biomass is made up of a mixture of, for example, compost, heather, coconut fibre and root wood. The pores of the biomass within which the micro-organisms are found are filled with water, partially free and partially fixed on the surface of the fixed material. During the passage of the contaminated air through the filter, the polluting substances move from the gas phase to the liquid phase. The micro-organisms then break these compounds down. To achieve this conversion, the micro-organisms need phosphate, sodium and calcium. These nutrients exist in a continuous cycle. However, some of these nutrients are drawn out of the biomass over time. It is therefore necessary to occasionally replace the biomass.When starting up a biofilter, there are already micro-organisms present in the biomass. The quantity of organisms is not sufficient to break down the polluting substances, so these organisms first need to multiply. It therefore takes a certain amount of time before a biofilter achieves optimum performance.
