Emission Limits

It is essential for your factory to comply with air emission limits on dust, vapors, and odors. Emission control systems are necessary to battle pollution and become part of the solution to improve air quality indoor and outdoor. Addressing a combination of these emission types requires a balanced, integrated design that prevents unnecessary future maintenance.

As factory processes and equipment often change rapidly, JOA filter units are built as easily extendable modules. Choosing the right filter principle, fume exhaust system, and filter media are key for a long-term sustainable solution.

In the over 2000 implemented systems, JOA has reduced waste-water streams, lowered pollution, improved air quality and energy efficiency for various FCMG, Pharma and Chemical manufacturers worldwide. Based on our experience, we prefer “dry” filter techniques over wet scrubbers. Also, we only apply wet scrubbers when the waste-water stream is recycled directly into the production process.

Dryer emissions in food and pharmaceutical applications have shown a great opportunity for effective energy recovery, producing steam and hot water. Other solutions are fully integrated fume exhaust systems, emission control, and air treatment systems. Read more about Energy Reduction & Recovery

How to comply with air emission limits and improve energy efficiency at the same time

Compliance with emissions ceilings for air pollutants in the form of gases and particles is essential for your factory. A good example of provided solutions is ammonium sulphate fertilizer plants. By utilizing JOA inline-venturi scrubber effluent as process make-up water, the wet-scrubbing system, in this case, delivers both environmental and economic benefits.

JOA helps factories to comply with emission limits (like the 2010/75/EU Directive), reducing pollution, and improving energy efficiency by recovering direct energy. The exhaust air from (spray) driers and flash towers can be used to recover the energy for direct steam or hot water generation. As a result, up to 70%, energy recovery efficiency is achievable.
