AlfaFlash ZLD
Reutiliza el agua y recupera el valor de tus residuos con un sistema AlfaFlash ZLD. Con el evaporador AlfaFlash y una centrífuga decantadora opcional, los sistemas ZLD eliminan eficientemente los sólidos de las aguas residuales y otros líquidos. Puedes recuperar valiosos materiales disueltos y suspendidos en tu proceso para reutilizar o vender. Si tienes un proceso que utiliza cantidades significativas de agua, puedes reciclarla y reutilizarla, reduciendo costos de eliminación.
Sistema modular o personalizado para ZLD y cristalización de procesos
- Eliminación de aguas residuales
- El agua destilada de alta pureza se puede reutilizar, recupera hasta el 98% del agua utilizada en el proceso
- Sólidos minimizados, para reutilización o costes mínimos de eliminación
- Alta eficiencia energética
- Instalación compacta pero robusta, ideal para una amplia gama de aplicaciones
Los sistemas AlfaFlash ZLD eliminan la descarga de aguas residuales líquidas, generan sólidos para su eliminación o reutilización, y reciclan agua destilada de alta pureza que puede reutilizarse de manera beneficiosa. El sistema AlfaFlash ZLD ayuda tanto al medio ambiente como a sus resultados y se ajusta fácilmente para cumplir con las regulaciones en constante cambio. La probada trayectoria de Alfa Laval y su amplia experiencia tanto en soluciones térmicas como en tecnología de separación garantizan una solución rentable.

Heat sources for evaporation system
Configuration Options
Alfa Laval evaporation systems can use heat from different sources such as mechanical and thermal compression as well as waste vapours from dryers.
Mechanical vapour recompression, MVR
- Low (or no) steam consumption
- Uses electricity
Multiple-effect system
- Saves energy by reusing steam
- Simple and flexible
Thermal vapour recompression, TVR
- Low cost with reduced steam consumption
- Simple, no moving parts
Waste heat from your process
- Utilize low grade steam or waste heat
- Recover energy from exhaust gases
Drive your evaporation process using heat recovered from exhaust gases
Combining Alfa Laval micro boiler into your evaporation system, you are able to drive your evaporation process using energy in your energy from your exhaust gases. The Alfa Laval Aalborg Micro is a uniquely compact boiler/economizer designed for waste heat recovery. This can help you to reduce energy consumption in your plant.
Working principle
Water is fed into the AlfaFlash heat exchanger. After heating fluid is then pushed through the flash orifice. The mixture is now essentially split in two phases – concentrate and vapour, which enters the cyclone separator where centrifugal forces boost vapour liquid separation. Vapour rises into space where mists and fine droplets are removed and the remaining concentrate flows into the recirculation pump. A side stream of concentrated liquid is then pushed through to the decanter where water is separated from solids.
Decanter centrifuge working principle
Alfa Laval decanter technology is used for dewatering suspended solids, resulting in minimum waste and maximum water recovery, with high removal efficiency for micro-particles as well. Watch the video to learn more!
