Enviroflex - Integrated Sludge Treatment System
Enviroflex GmbH, located in Austria, specializes in advanced solutions for municipal and industrial sludge treatment, focusing on solid-liquid separation technologies. The company offers integrated systems for effective sludge thickening and dewatering, featuring high-performance belt presses and belt thickeners. These systems are designed for efficient processing of various sludge types, optimizing moisture content and minimizing waste. The HTE3-2000L model integrates a gravity belt thickener with a belt filter press, compactly designed for energy efficiency and automation. The process involves flocculating raw sludge to remove water through a porous belt, proceeding to compression between belts for making a dry sludge cake. This method ensures high solids content, efficient water usage, and low operational costs. The equipment includes advanced automation and user-friendly interfaces compliant with CE and ISO standards, ideal for both municipal and industrial applications.
Enviroflex GmbH, based in Austria, is a leading provider of innovative solid-liquid separation technologies. With years of expertise in the field, we specialize in complete, tailor-made solutions for municipal and industrial sludge treatment—from primary thickening to final dewatering.
Our current catalogue focuses exclusively on our high-performance belt presses and belt thickeners, engineered to deliver reliable, efficient, and cost-effective results for a wide range of sludge types.
Product Highlights
- Gravity Belt Thickeners: Ideal for thickening dilute sludge (e.g., primary or secondary sludge) to a manageable consistency, minimizing volume before further treatment or disposal.
- Belt Filter Presses: Designed for continuous dewatering of thickened or illiquid sludge, producing a dry cake with high solids content.
- Integrated Systems: Combined units with both belt thickener and stages in one frame—perfect for thin sludges like waste activated sludge (WAS), offering a compact and fully automated process.
- High Capture Rate – Advanced belt and roller design ensures minimal solids loss in filtrate (typically <1%), protecting downstream systems and optimizing efficiency.
- High Dry Solids Content (DS%) – Precision-engineered pressure and shear zones, including high-pressure „tension“ rollers, achieve excellent cake dryness, even with difficult sludges.
- Low Wash Water Consumption – Efficient belt cleaning systems reduce water use and operational costs.
- Wide Belt Selection – High-quality belts available in various weave patterns, air permeability, and chemical resistance grades, customized for specific sludge characteristics.
- Robust, Low-Maintenance Design – Built for long service life with corrosion-resistant materials and minimized mechanical complexity.
- Flexible Operation – Adjustable belt speed, pressure zones, and polymer dosing for optimized performance under varying sludge loads.
- Fully Automated Control Systems – Integrated with user-friendly HMIs and optional SCADA interfaces for remote monitoring and process optimization.
- Compact Footprint – Space-saving designs available for containerized and retrofit applications.
In addition to manufacturing the belt thickening and dewatering units, we supply and integrate the full process chain:
- Sludge feed tanks and pumps
- Polymer preparation and dosing units (powder or emulsion)
- Polymer mixing and maturation tanks
- Sludge conveyors (screw, belt, shaftless)
- Filtrate handling systems
- Electrical control panels and automation (with CE compliance and ISO-certified production)
