How SDI Works
Smart De-Ionization (SDI) purifies water using a low-voltage electric field and ion-selective membranes to remove dissolved salts and minerals — without the use of salt, chemicals, or high pressure. It’s a clean, energy-efficient, and eco-friendly alternative to traditional RO and softeners, delivering high-purity water with minimal waste and maintenance.
When water passes through the SDI unit, the electric field causes positively and negatively charged ions to migrate through specially designed membranes. These membranes allow only the target ions to pass, effectively separating them from the purified water stream. This results in soft, low-TDS water suitable for a variety of industrial and commercial applications.
One of SDI’s biggest advantages is its fully automatic Cleaning-in-Place (CIP) system, which flushes out the captured ions without manual maintenance or chemical regeneration. The system consuming up to 75% less electricity than reverse osmosis, and delivers up to 80% water recovery, minimizing waste.
Process Overview:
1. Ion Separation Using Electric Field :- Raw water enters the SDI system, where a low-voltage electric field is applied. This field causes the dissolved ions (such as calcium, magnesium, sodium, and chloride) to move toward oppositely charged electrodes.
2. Selective Ion Exchange Through Membranes :- Inside the system, ion-selective membranes allow only the charged ions to pass through, separating them from the purified water stream. These membranes act as filters that selectively remove salts without blocking the water itself.
3.Continuous Water Purification :- The pure water continues through the outlet, while the separated ions are directed to a waste stream. This ensures a steady flow of de-ionized water with consistent quality.
4. Automatic Cleaning-in-Place (CIP) :- To keep the system clean and efficient, SDI uses automatic CIP — a self-cleaning process that flushes out the collected ions, eliminating the need for manual cleaning or salt regeneration
Benefits of Using SDI
- High Water Recovery Rate :- SDI systems can recover up to 90% or more of water, significantly reducing wastewater generation. This makes it more efficient than traditional reverse osmosis systems, which often waste large volumes of water.
- Low Energy Consumption :- Unlike RO or thermal processes, SDI works on electro-deionization principles that consume very low power, resulting in reduced energy bills and a smaller carbon footprint.
- No Chemical Usage :- SDI is a chemical-free water treatment technology. It eliminates the need for acid or caustic regeneration typically used in ion exchange resin systems, making the process safe, sustainable, and eco-friendly.
- Compact & Modular Design :- SDI units are space-efficient and modular, allowing for easy installation even in areas with limited space. This is especially beneficial for hotels, hospitals, and urban buildings.
- Low Maintenance Requirement :- The system is designed for long-term use with minimal maintenance, reducing the need for frequent servicing, consumables, or part replacements—translating into lower operational costs.
- Consistent and Reliable Water Quality :- SDI technology maintains stable water purity over time without quality fluctuations, ensuring compliance with required standards in sensitive applications like healthcare, laboratories, and hospitality.
- Plug-and-Play Installation :- SDI systems are pre-engineered and easy to install, cutting down commissioning time and making them ideal for quick project turnarounds.
- Environmentally Friendly :- With zero chemical discharge and high efficiency, SDI contributes to greener infrastructure and helps industries meet sustainability goals and regulatory norms.
Applications of SDI System
- Water Treatment for schools, hospitals , offices, hotels, restaurants, shopping malls, and bungalows.
- Water ATMs or water purification for public areas.
- General water treatment for commercial and industrial purposes.
- Water treatment for boiler, cooling towers, laundry, or other industrial or commercial and industrial or commercial machines.
- Retrofit to demineralization plants or RO plants to reduce operating costs or avoid frequent breakdowns.
