DEPURGAN is a treatment system for cattle purines (porcine and bovine) with its own patent and with different locations within Zaragoza.
The aim is to reach the treatment capacity of 20 m3 of purine and reduce principal components that suppose an environmental hazard. Such as nitrogen, phosphorus, organic matter and heavy metals.
This is obtained by a succession of physical-chemical treatments. In this case there are following treatments: homogenization, solid-liquid separation by centrifugation, coagulation-flocculation and solid liquid separation by electrocoagulation.
Are obtained two residuals: solid and liquid. The solid residual is used for manufacturing of pellets, with an equal mixture of manure and pine wood. Liquid residual is used for liquid fertilisers.
