Sulphus for Waste Water Treatment odour of Ence (Spain)

Zwolle/Madrid | 01-11-2011

Pure Air Solutions received the order from ENCE to supply 2 odour control systems. The SULPHUS 3000 will be installed to treat air from the sludge treatment and sludge storage building of the plant in Ponteverda (Spain).

The Sulphus is specially designed for the treatment of odours related to H2S and other (in)organic odour compounds. The technology is based on the biological removal of the compounds, therefore no chemicals are necessary. Typical removal rates are 99% on H2S and 95% on odour. The Sulphus is fully corrosion resistance and has a synthetic packing material. With the multilayer media beds ENCE is ensured that at various pH gradients H2S and organic odours, such as VOC’s and mercaptans, are removed with high efficiencies at the lowest cost.

Ence is a reference in the production of market pulp and energy from planted biomass as an example of a business - like Pure Air Solutions - committed to the sustainable development and the mitigation of climate change. The business activity of the group is based on the cultivation, promotion, and exploitation of forest species for the production and extraction of wood and biomass, and the subsequent processing of these into pulp and energy. The company manages approximately 116,000 hectares of forests in Spain, Portugal, and Uruguay, and complies with the most demanding international requirements in the field of Sustainable Forest Management. Ence has three industrial complexes in Spain (Huelva, Navia in Asturias, and Pontevedra) with the capacity to produce 1.3 million tonnes of pulp and 1.7 million MW h of renewable electricity.
