Hemodialysis Water Treatment Medical Grade Veolia MK-3MiniHT Suez EDI Stacks 1.14 M3/H Compact EDI

Dialysis centers treat thousands of patients every week, and the water used to prepare dialysis fluid must be biologically and chemically controlled far beyond ordinary drinking water standards. Water treatment systems designed for hemodialysis applications rely on electrodeionization to reduce ionic contaminants continuously after reverse osmosis. The Veolia MK-3MiniHT Suez EDI stack brings this proven E-Cell technology into a compact 57 kg package that fits the machine rooms of clinics and hospital dialysis units.

The MiniHT is the hot water sanitizable member of the Mini family. Its design tolerates repeated sanitization cycles at up to 85 deg C, which is essential in medical water loops where biofilm control decides patient safety. Because the stack regenerates electrically, dialysis facilities avoid the shift-to-shift quality swings associated with chemical regeneration and eliminate caustic handling inside hospital buildings.

• Hot water sanitization: withstands sanitization at up to 85 deg C and 160 documented cycles, supporting the disinfection regimens required in medical water loops.
• Compact footprint: measures only 30 x 61 x 29 cm and weighs 57 kg, allowing wall-adjacent or skid-mounted installation in small treatment rooms.
• Stable ionic removal: delivers resistivity of at least 10 MOhm-cm in pharmaceutical configuration or 16 MOhm-cm in industrial configuration, with sodium below 3 ppb.
• Continuous operation: produces purified water 24 hours a day without acid or caustic regeneration, matching the duty cycle of dialysis departments.
• Low energy consumption: the E-Cell electrodeionization process consumes only electric power and feed water, keeping operating cost predictable.
• Proven E-Cell reliability: built on the same plate-and-frame platform as the full E-Cell range with CE, UL and CSA certification.
• Modular redundancy: two or three stacks can be arranged in duty-standby configuration so sanitization or maintenance never interrupts water supply.

When integrated into a complete hemodialysis water treatment system designed to meet AAMI and ISO 13959 water quality guidance, the MK-3MiniHT provides the polishing stage between reverse osmosis and the dialysis fluid delivery loop. Its small hourly output matches the demand of 10 to 30 station dialysis units, while hot water sanitization keeps the distribution loop safe.

The same stack serves hospital clinical laboratories, endoscopy washer-disinfector feed water and medical device rinse applications where compact size, low bacteria growth potential and sanitization compatibility are decisive. For larger facilities, multiple MiniHT stacks are combined in parallel with automatic duty cycling.

The MK-3MiniHT is shipped in a dedicated foam-lined carton with the stack sealed against moisture, together with the sanitization logbook template, installation guide and factory test certificate. Export packing meets air and sea freight requirements, and stock delivery is 5-8 working days.
