3. Sustainable & Maintenance-Free Operation
Modern industries are increasingly focused on reducing environmental footprint and operating costs (OPEX). The STK-N04-1.0 is designed to meet these "Green Manufacturing" standards.
Eliminate Disposable Filter Bags
Traditional bag filters require frequent manual intervention to replace dirty bags, creating a cycle of recurring costs and generating hazardous solid waste soaked in pollutants. The STK-N04-1.0 utilizes a permanent SS316 Stainless Steel Filter Screen. This durable screen is automatically cleaned and reused, eliminating the need to ever buy or dispose of filter bags again.
Eco-Friendly Water Treatment
- Zero Consumables: No disposable plastic or fiber waste is generated during operation.
- Water Saving: The intelligent cleaning cycle is precise and short, significantly minimizing wastewater discharge compared to sand filters or manual backwashing.
- Energy Efficient: Driven by a high-efficiency 0.37KW Motor, the system consumes minimal electricity.
4. Premium Component Configuration
To ensure long-term reliability, the STK-N04-1.0 integrates top-tier global brands, distinguishing it from standard market alternatives.
- Drive System (German SEW Motor): The cleaning cycle is powered by a SEW-EURODRIVE motor. Known for high torque and durability, this motor ensures the cleaning shaft rotates smoothly.
- Intelligent Control (Siemens PLC): The brain of the system is a Siemens PLC equipped with an LCD display. It offers precise logic control for timing and differential pressure monitoring.
- Electrical Safety (Schneider Electric): Internal electrical elements are sourced from Schneider Electric, ensuring circuit stability.
- Discharge System (Covna Valve): A DN40 Electric Drain Valve from Covna handles the discharge, featuring a fast response time.
5. Operational Sequence & Working Principle
The STK-N04-1.0 utilizes a smart differential pressure (DP) monitoring system to trigger self-cleaning without interrupting the main water flow.
Filtration Phase
Raw water enters through the DN100 inlet and passes through the permanent SS316 Screen. Impurities are trapped on the screen surface, while clean water flows to the outlet.
Self-Cleaning Phase
When the differential pressure reaches the preset value, the Siemens PLC initiates the cleaning cycle:
- The Covna Drain Valve opens.
- The SEW Motor rotates the cleaning device (SS316 shaft and brushes).
- Impurities are scrubbed off the screen and flushed out through the drain.
Note: The system continues to supply filtered water during the cleaning cycle.
6. Material Specifications
