Food Grade Sanitary EDI Equipment for Eco Friendly Operation

This Low TDS EDI System is professional high-standard water purification equipment specifically developed for food processing, beverage production, drinking water processing, and food factory process water preparation. The food and beverage industry demands extremely strict water cleanliness and stability standards. Excessive dissolved solids, trace minerals, and residual impurities can directly impact product taste, transparency, shelf life, and overall quality.

Traditional water treatment equipment often fails to maintain consistent low TDS output, leading to unstable production water quality. Our system employs advanced electrodeionization technology combined with two-stage RO pretreatment, achieving deep removal of dissolved solids, micro impurities, and trace electrolytes. The system supports fully automatic, chemical-free continuous operation, reliably providing low TDS high-purity process water with food-grade safe construction, stable purification performance, and low operating costs.

Pre-treated water undergoes two-stage RO purification before entering the professional food-grade EDI membrane stack. Under a stable DC electric field, the high-efficiency ion exchange resin thoroughly adsorbs residual dissolved solids, trace cations, and anions. Impurity ions complete directional migration and separation through selective ion exchange membranes, with concentrated discharge through independent water channels.

The equipment achieves automatic electric regeneration of internal resin during continuous operation without chemical additives, eliminating residual pollution and ensuring hygienic water quality. Equipped with high-precision online TDS and resistivity monitoring modules, the system dynamically adjusts operating parameters according to inlet water variations, maintaining continuous stable low TDS water output to meet long-term hygienic production requirements.

• Stable Low TDS Water Output: Effectively removes dissolved solids and trace electrolytes, maintaining long-term low TDS high-purity water status to ensure consistent taste, color, and product quality.
• Food-Grade Sanitary Structure: All water-contact components use hygienic, harmless materials with smooth inner walls and no dead corners, preventing impurity accumulation and bacterial growth while complying with food production standards.
• Non-Chemical Eco-Friendly Operation: Automatic electric resin regeneration eliminates chemical dosing, chemical residues, and waste liquid pollution, ensuring pure and safe process water environments.
• Continuous Stable Purification Performance: Optimized food-grade membrane stack structure with strong anti-interference capability ensures no water quality fluctuations during long-term full-load operation.
• Fully Automatic Intelligent Operation: Complete automatic control and real-time water quality monitoring system enables 24-hour unattended stable operation, reducing manual errors and labor costs.
• Low Maintenance & High Cost Performance: Modular integrated structure simplifies daily inspection and maintenance, featuring low failure rates and long service life to reduce long-term operational costs.
