Taim Weser sets up Barcelona waste treatment plant
27 Sep 2010
Saragossa, Spain – Taim Weser (TW) has concluded pre-commissioning tests on its installation for the new Vallés Occidental waste treatment plant in Vacarisses, Barcelona. The installation comprises a complete composting plant for the organic fraction of urban waste.
Having completed the installation of TW’s equipment at the new Vallés Occidental waste treatment plant, the Vallès Occidental WTP, pre-commissioning testing of all the new equipment, as well as of the plant control and automation systems, took place during June and July.
TW was responsible for the engineering and supply of two automatic loading systems, two automatic stack turner machines, a discharge system, an aeration system, as well as assembly and start-up of the installation.
The TW installation features an organic waste composting plant, for the organic fraction of urban solid waste, which stabilises this fraction using trapezoidal stacks in enclosed fermentation chambers.
Stabilisation is carried out in two halls, each with an exhaust draft aeration system, a feed system and a stack turner, the end product of which is suitable for landscaping or gardening. The stack turning stabilisation system is fully automated and operates within the closed hall without any human intervention.
This stabilisation plant is scheduled for start-up by the end of 2010. It will have an organic waste treatment capacity of 154,000 t/a, to be produced by the mechanical treatment section of the Centre.
The Vallès Occidental WTP covers 43,900 m2, with a gross floor area of 37,128 m2 and a municipal waste treatment capacity of 254,000 t/a, and 40,000 t/a of organic fraction from selective treatment.
The Centre is composed of two plants, one for composting the organic fraction of urban solid waste, which houses the equipment supplied by TW, and one for treatment of the organic fraction of pruning waste, which is sent directly to the plant.
The launch of the new centre will allow the gradual but full decommissioning of the Coll Cardús landfill, which, after 30 years storing waste from the Vallés Occidental, is now close to its storage capacity limit.
