Evaluation of increase at the production of keratinolytics enzymes

The beamhouse area in leather technology has a notable influence on the gaseous and liquid effluent because they have to satisfies discharge standards. The organic matter content and the presence of suspended solids in the liquid effluent greatly depend on the unhairing process used: the conventiona...
