Donaldson Tackles Emission Control Issue for Waste & Incinerator Plant 1

The community-owned plant incinerates household waste including furniture, but did not have the required environmental protection control systems in place.

Today’s stringent environmental legislations aim to prevent effects of pollution from incineration and the subsequent risk to human health. Therefore incineration plants may only be granted permits to incinerate hazardous waste if they have procedures in place to control and limit emissions, as outlined on www.wasteonline.org.uk’s waste guide:

Here its states that:“Directive 89/429/EEC on existing municipal waste incinerators introduced a programme of phased improvement for existing plants, whereby emission limit values must be met within certain time limits. Extensive requirements for monitoring, inspection and reporting by the operators of these plants are laid down in this Directive.”

The Directive sets mission limits which necessitate the use of strict operational conditions and technical requirements, therefore the plant was in urgent need of an effective filtration solution if it was to continue to operate.

This necessitated the installation of a new filter house manufactured by an expert in industrial ecology and advanced technology and in the treatment of fumes from incinerating urban and industrial waste.

However, after 12 months the originally installed filter media was not meeting the legislative standards required and Donaldson Membranes, known internationally for its manufacture of Tetratex® expanded polytetrafluoroethylene (PTFE) membranes was asked to resolve the serious emission problem caused by this failure.

Following consultation between local bag supplier EM-TEK in Györ, Hungary, and Donaldson Membranes Sales Manager, Wolfgang Drong, it was decided that #6255 Tetratex Ultra High Efficiency Woven Glass fabric, suitable for continuous service at temperatures of up to 2600C, would be the most effective media for plant’s operation - and 1,200 sleeves, dia.126 x 6,330 (mm), volume = 180,000 m³/h, were manufactured and installed.

After more than 18 months of operation the plant manager is delighted with performance of the ultra high efficiency media, and continuous monitoring shows that Donaldson Membranes’ #6255 Tetratex Ultra High Efficiency Glass fabric filter media has resolved the emission problem, maintaining levels well below the acceptable of 10 mg/m³.
