Stark 500 LPH automatic stainless steel two-stage reverse osmosis filters system EDI device

In industries where the slightest impurity can compromise product integrity, process efficiency, or analytical accuracy, ultra-pure water is an absolute necessity. The Stark Water 500 LPH Automatic Stainless Steel Two-Stage Reverse Osmosis Filters System EDI Device is meticulously engineered to meet these exacting demands, providing a compact yet powerful solution for continuous production of ultra-pure water. This system represents a fusion of advanced filtration technologies, ensuring uncompromised purity and reliable performance.

The Precision of a Two-Stage Reverse Osmosis Filters System

Our system begins with a sophisticated two-stage reverse osmosis filters system. While a single RO stage effectively removes the majority of dissolved solids and contaminants, a second RO pass further refines the water. This sequential purification significantly reduces residual ions, ensures higher overall contaminant rejection, and provides an exceptionally pure feed for the subsequent EDI process. This robust pre-treatment is crucial for maximizing the efficiency and extending the lifespan of the EDI device. With a capacity of 500 LPH (500 liters per hour or 0.5 m³/hr), this system is ideally suited for small to medium-scale industrial, laboratory, and commercial operations requiring consistent volumes of highly purified water.

Integrated EDI Device: Chemical-Free Ultra-Pure Water Polishing

The true heart of this ultra-pure water solution is the seamlessly integrated EDI device (Electrodeionization). Taking the high-quality permeate from the two-stage RO, the EDI device elevates water purity to ultra-pure levels, typically achieving resistivity values between 16 and 18 MΩ·cm (megohms per centimeter). EDI technology uniquely combines ion exchange resins and ion-selective membranes with an applied electrical current to continuously remove remaining dissolved ions. The key advantage of this EDI device is its chemical-free regeneration:

• No Hazardous Chemicals: Eliminates the need for costly and dangerous acids and caustics traditionally used to regenerate ion exchange resins, enhancing operator safety.
• Continuous Operation: Provides an uninterrupted supply of ultra-pure water, avoiding downtime associated with batch chemical regeneration cycles.
• Reduced Waste: Minimizes the generation of hazardous chemical waste, aligning with environmental sustainability goals and reducing disposal costs.

This ensures the final output water is not only exceptionally pure but also produced with optimal safety and environmental responsibility.

Robust Stainless Steel Construction & Automated Operation

The STARK 500 LPH system is built with durability and hygiene in mind, featuring comprehensive stainless steel construction (typically SUS304 or SUS316L for all critical wetted parts and frame). Stainless steel offers superior corrosion resistance, structural integrity, and hygienic properties, crucial for high-purity water applications. Furthermore, the system is fully automatic, incorporating an intelligent control system (PLC with HMI) that provides real-time monitoring of water quality (e.g., conductivity/resistivity at multiple points), pressure, and flow. Automated functions like auto-flush and cleaning-in-place (CIP) cycles simplify operation and maintenance, ensuring consistent performance, minimal manual intervention, and reliable ultra-pure water output for sensitive processes.
