ALDRUM G3
El filtro de tambor rotativo Aldrum G3 de Alfa Laval establece un nuevo estándar para el espesamiento de lodos. El espesador de lodos espesa eficazmente los lodos para optimizar los procesos posteriores, aumentando la producción de biogás y reduciendo los costes de deshidratación. Su diseño mejorado, que incluye un filtro de tambor rotativo y una eficiente tolva de lodos, mejora el rendimiento y mantiene bajos los costes operativos.
Experimente el rendimiento simplificado con un revolucionario espesador de lodos
- Mayor capacidad en el mismo espacio
- Bajo consumo de polímeros, lo que garantiza bajos costes operativos
- Instalación en exteriores del espesador de lodos, si es necesario
- Enclosed design for a clean, odourless working environment
- Mantenimiento sencillo con sistema de limpieza in situ que utiliza agua potable, efluente final o filtrado tratado
Los espesadores de lodos son óptimos para el espesamiento de lodos de capacidad media a grande, mejorando la eficiencia del proceso y logrando una deshidratación más rentable. Los lodos que normalmente necesitan polímero líquido para la floculación y el espesamiento pueden tratarse con un polímero en polvo más económico, reduciendo así los costes operativos. El diseño del transportador del espesador de lodos mejora la eficiencia, mientras que el interruptor de la cubierta y la cubierta a prueba de golpes mejoran la seguridad. El Alfa Laval Aldrum G3 es capaz de manejar capacidades que van desde 15 a 180 m³/h.
Rotary drum filter for medium-to-high-capacity sludge thickening
By utilizing advanced technology, including components like the rotary drum filter, the sludge thickener system enhances process performance while minimizing operating costs. It is suitable for a wide range of applications, including all types of municipal wastewater sludge, industrial separation (such as in paper production and solid waste processing), and fresh water production at waterworks. Additionally, the optimized design of the sludge hopper ensures efficient collection and handling, contributing to a streamlined sludge management solution.
How does the sludge thickener equipment work?
The sludge thickener works on the principle of conveying polyelectrolyte-treated sludge (a.k.a. flocculated sludge) through a slowly rotating drum filter. Inside the drum, the sludge is retained while water passes through the filter cloth. Thanks to intermittent cleaning with spray nozzles, water consumption remains low, as the drum can be flushed using potable water, final effluent, or treated filtrate.
You can achieve the most efficient thickening by varying the feed rate, the polymer type and dosage, drum speed and spraying interval. You get the most cost-effective flocculation and polymer dosage by installing a flocculation reactor and/or mixing valve upstream of the actual drum thickener. A variety of rotary drum filter cloths are available for new applications.
Alfa Laval's Aldrum G3 drum thickeners are renowned for their robust, straightforward design, extremely durable filter cloth, and low maintenance requirements. They are also equipped with an integrated Cleaning-in-place (CIP) flushing system.
Discover our range of auxiliary equipment
- Mixing valve: Ensures thorough mixing of polymer and sludge, which reduces polymer consumption. Can be installed directly on to the drum thickener inlet or before the flocculation reactor
- Flocculation reactor: Simple open reactor that kick-starts the creation of large and strong flocks. Can be installed directly onto the drum thickener inlet
- Sludge hopper: Leads the thickened sludge to the sludge pump in a controlled and efficient manner
- Basic control panel: For easy control of the drum thickener, including control of the level in the flocculation reactor (if fitted)
- Advanced control panel: All-in-one control solution. Control of the plant’s feed pump, sludge pump and polymer pump, as well as the drum thickener, the level in the flocculation reactor and the sludge hopper
