INCREASE YIELD, REDUCE ENERGY AND OPERATING COSTS The tannery industry is an important economic sector in many countries, but it is associated with significant environmental impacts. The biggest challenges for tanneries are the high amounts of water consumed and the contamination of wastewater with chemicals, heavy metals, and organic substances. Industrial centrifuges play an important role in optimizing tannery processes. They make it possible to generate additional profit from process side streams. At the same time, they reduce the direct and indirect costs of the industrial tannery through...

Flottweg supports you in optimizing industrial leather production with the following services, among others: ∙ ∙ ∙ ∙ Separation of valuable raw materials in limed fleshings with the Flottweg Tricanter® Separation of these raw materials into protein and fat for reuse or resale Reduction of non-recyclable residues to approx. 10% of the original quantity Fully automated centrifuge technology as a contribution to sustainable tannery Flottweg is certified to DIN EN ISO 9001:2015 and manufactures its products in compliance with the latest technical standards. Your advantages with Flottweg separation...

SUCCESS IS … INCREASED YIELD THROUGH PROCESSING OF LIMED FLESHINGS The Flottweg Tricanter® complete system for tanneries shreds and heats the limed fleshings before separating them into water, fat, and solids. ∙ ∙ ∙ ∙ Efficient separation leaves only 10% organic material for disposal The recovery of valuable fat creates an efficient overall process The simple (optionally, fully automatic) process requires no additional chemicals and takes place in a safe, closed system Various plant sizes, integration into existing processes, and even complete process lines are possible Effluent to treatment...

Special features of the Flottweg Tricanter® Flottweg Tricanters® are used for the simultaneous separation of liquid, fat and solids (3-phase process). Due to the special design of the impeller and the rotor, the re-mixing of water and fat phase after separation (e.g. due to swirling) is practically excluded. As a result, the Tricanter® achieves a very high purity in the separated fat phase. Often, the Tricanter® is preferred in 3-phase processes because the investment and operating costs are significantly lower than in comparable processes with decanter and separator. Liquid discharge Solids...

SUCCESS IS … PROTECTING THE ENVIRONMENT, REDUCING WASTEWATER COSTS The Flottweg decanter for tanneries pretreats the contaminated wastewater for the subsequent treatment stages. This reduces the overall effort and increases the capacity of these cleaning stages, after which the wastewater can be discharged to wastewater treatment plants or reused as process water. ∙ ∙ ∙ ∙ he wastewater is pretreated by removing organic solids (residual tissue, fur, etc.) T Sludges from upstream conditioning stages (biological and surplus sludges) are thickened (reduced) The chemicals bound in the solids (e.g....

Special features of the Flottweg decanter The “Big Five” – this is what matters in wastewater treatment: ∙ Dry matter content ∙ Throughput ∙ Polymer requirement ∙ Energy consumption ∙ Reverse contamination in the centrate (separation efficiency) Flottweg decanters are used in wastewater treatment to separate liquids from (contaminated) solids (2-phase process). In the Flottweg decanter, a high dry matter content is achieved for these separated solids, together with a high throughflow. Mechanical separation requires less energy than thermal separation and decreases the use of polymers. The amount...

FLOTTWEG FLOTTWEG QUALITY QUALITY AND AND SERVICE SERVICE Guaranteed Flottweg quality Made in Germany: We have a clear vision of quality and make no compromises. In the tannery industry, our products must withstand chemicals and heavy metals. For this reason, components of Flottweg centrifuges that come into direct contact with the medium that will be processed (including the bowl, scroll, and inlet), are exclusively made from high-quality, corrosion- and acid-resistant steel. This means higher strength and improved resistance. Our machines are well-equipped and can meet your requirements in...
