Recycling & ZLD

Sustainable conservation of resources

Wertstoffe, die recycelt werden können, darunter Glas, Metalle, Kunststoffe, Batterien uvm.

Recycling & ZLD are important processes with a positive impact on the environment, economy and society. By sustainably activating recyclable materials, we can conserve resources, reduce the need for new raw materials, minimize waste, save energy and reduce greenhouse gas emissions. With increasing environmental challenges and limited resources, recycling is an important part of building a sustainable future.

Recycling & ZLD – for a sustainable future and a healthy world!

For decades, the global scarcity of resources and raw materials has led to the sustainable activation of recyclable materials that are fed back into the value chain.

With the CONTURBEX screen scroll centrifuge, our customers dewater, for example, X-ray films for the recovery of silver, plastic granulates from car recycling or HDPE from the recycling of beverage packaging. We develop the necessary special slotted screens or CONIDUR® screens for dewatering in-house.

The salt contamination of waste water, e.g. from the power plant industry or the potash industry, must be minimized. This is achieved using Zero Liquid Discharge (ZLD) systems, among other things. In this application, dewatering is carried out using decanters, SHORTBOWL decanters, pusher centrifuges and CONTURBEX centrifuges. Our HSG vibrating centrifuges have proven themselves for dewatering coarse residue.

Finer mixed salts from crystallization systems are centrifuged with downstream SHORTBOWL decanters, pusher centrifuges and CONTURBEX centrifuges at temperatures sometimes exceeding 100°C. The high-alloy stainless steels, Hastelloy and titanium materials required for these machines are provided with appropriate wear protection made of tungsten carbide, stellite or ceramic tiles. In this innovation-driven market, we are constantly developing new and more efficient solutions for coating, bonding and joining technology for our customers.
