Dal Prete Engineering at Stone+tec Nuremberg 2026: Presenting Water Treatment Solutions to the Stone Industry

Stone+tec Nuremberg, the international trade fair and congress for natural stone and stone processing, provides Dal Prete Engineering with a strategic platform to present its water treatment technologies to stone fabricators, quarries, and ceramic producers. Located in Hall 12, Stand B28, Dal Prete Engineering will showcase its water clarification, filtration, and sludge dewatering systems—technologies that address critical operational challenges in stone processing: water consumption, tool lifespan, sludge disposal costs, and environmental compliance. The fair serves as a venue for demonstrating how closed-loop water recycling (Water Loop) from Dal Prete Engineering improves resource management and reduces operational expenses.

Key Performance Improvements from Dal Prete Engineering: Quantifiable Benefits for Stone Processors

Dal Prete Engineering documents specific performance improvements achievable with its automated water treatment systems:

Tool lifespan : Extended by up to 20% through consistent water quality—clean, clarified water from Dal Prete Engineering reduces abrasive wear on diamond tools and processing equipment.

Water consumption : Reduced by up to 30% through closed-loop recycling systems from Dal Prete Engineering that eliminate the need for fresh water from external sources, recirculating clarified water indefinitely.

Sludge disposal costs : Reduced by up to 50% through Dal Prete Engineering’s continuous sludge dewatering technology that compacts waste, reducing volume and simplifying handling and disposal.

Production downtime : Reduced by up to 30% through Dal Prete Engineering’s fully automated processes for clarification, filtration, sludge dewatering, and routine maintenance—scheduled during convenient production windows.

Labor hours required : Reduced by up to 80% by eliminating low-value sludge handling tasks that previously required skilled labour, thanks to Dal Prete Engineering solutions.

Human error : Reduced by up to 90% through automation of water management processes from Dal Prete Engineering, eliminating manual intervention and associated mistakes.

The Water Loop by Dal Prete Engineering: Closed-Loop Water Recycling Technology

Dal Prete Engineering’s technology is based on the concept of continuous waste extraction—a fundamental departure from traditional sedimentation tanks and big bag systems, which rely on residue accumulation. The continuous extraction approach enables a closed-loop water recycling system (the Water Loop) that:

• Eliminates the need for fresh water from external sources for most operations, reducing dependency on municipal water supplies and lowering utility costs

• Recovers over 80% of remaining water during the dewatering phase, with compacted sludge tiles produced as final waste

• Maintains consistent water quality for processing equipment, preventing scale buildup and abrasive particle damage

• Creates a cleaner, safer working environment by eliminating stagnant sedimentation ponds, wet sludge storage, and associated odours and safety hazards

• Simplifies sludge handling and disposal, with dewatered sludge potentially reusable as raw material in other sectors depending on composition

Product Portfolio of Dal Prete Engineering: Water Clarification, Filtration, and Sludge Dewatering Systems

Dal Prete Engineering offers a wide range of technologies for industrial water management:

Water Clarification Systems : Remove suspended solids from process water, producing clarified water suitable for immediate reuse in stone cutting, polishing, and grinding operations.

Filtration Systems : Further refine clarified water from Dal Prete Engineering to achieve higher purity levels for applications requiring ultra-clean water, such as precision cutting or surface finishing.

Sludge Dewatering Systems : Continuous extraction technology from Dal Prete Engineering that compacts residual sludge into manageable tiles or blocks, reducing volume and recovering additional water for recycling.

Complete Water Recycling Plants : Integrated systems from Dal Prete Engineering combining clarification, filtration, and dewatering in a single compact footprint—eliminating the need for large sedimentation tanks or big bag handling areas.

Air Treatment Solutions : Additional offerings from Dal Prete Engineering for production environments, addressing air quality and dust control in stone processing facilities.

All systems from Dal Prete Engineering are fully automated, designed to eliminate human error and schedule maintenance during the most convenient production windows.

Compact Design by Dal Prete Engineering: Space-Efficient Solutions for Stone Workshops

Dal Prete Engineering’s solutions are known for their ultra-compact design. The clarification, filtration, and dewatering processes are all managed in a single integrated area, leaving more space for core production needs. This eliminates the need for:

• Large sedimentation tanks that consume valuable floor space

• Dedicated areas for big bag handling and storage

• Separate sludge drying beds or external disposal staging areas

For stone fabricators operating in space-constrained workshops—common in urban or industrial park settings—Dal Prete Engineering’s compact footprint allows water treatment integration without sacrificing production capacity.

Six-Step Method of Dal Prete Engineering: From Analysis to Ongoing Support

Dal Prete Engineering follows a structured six-step methodology for each customer engagement:

1. Company Analysis : Analysis of the water management system using a global approach divided into seven points (the Water Loop). Data collected includes water consumption, types of materials processed, quantity and location of production machinery, residual sludge volume, and internal production organization.

2. Water Testing : Analysis of wastewater to identify the right combination of products for clarification and filtration, ensuring water is clean and 100% reusable for endless production cycles.

3. Solution Identification : Design of customized hardware and software solutions by Dal Prete Engineering to maximize production performance and efficiency—ensuring water supply required by machines, minimizing time and resource waste, and improving workers’ quality of life by eliminating degrading and dangerous tasks.

4. Installation and Commissioning : Installation exclusively by Dal Prete Engineering qualified technicians, including on-site technical inspections, initial training, system configuration, and personnel training.

5. Training and Consolidation : Training for customer’s team of users and maintenance staff, followed by a re-training session after one month to consolidate knowledge and autonomy.

6. Support and Warranty : Customer support service from Dal Prete Engineering providing quick responses in 5 languages for immediate assistance. Network of distributors and technicians worldwide ensures continuous support both on-site and remotely, with scheduled periodic maintenance and warranty extensions available.
