Overview: The document provides detailed information on fully automatic demineralisers, specifically the DME, DMHE, and DMCE series. These systems are designed for water treatment, utilizing a two-column ion exchange process to remove dissolved salts from water.
Specifications: The DME and DMHE series are co-current regenerated systems, meaning water and regeneration chemicals flow in the same direction through the ion exchangers. The DMCE series uses counter-current regeneration, where chemicals flow in the opposite direction to water, enhancing efficiency and reducing chemical use.
Design and Features: The systems are skid-mounted and compact, featuring advanced electronic control units for programming and continuous quality surveillance. They operate on a safe low-voltage control system (12 V supply) and include a circulation pump to prevent standstill phenomena.
Regeneration Process: The regeneration involves backwashing, acid or sodium hydroxide draw, and rinsing. The process can be adjusted based on raw water quality and working conditions. The DMCE series offers improved water quality with lower chemical consumption.
Water Quality and Capacity: The demineralised water typically has a conductivity below 20 microsiemens, suitable for most industrial processes. The plant capacity is determined by the salt content of the inlet water, measured in equivalent hardness.
Control and Monitoring: The control panel allows for time-adjustable cycles and remote alarms. The conductivity meter monitors water quality, with alarms triggered if quality limits are not met. Duplex control is available for continuous water supply, allowing automatic switching between units.
Applications and Benefits: These systems are ideal for industries requiring high-quality demineralised water with minimal chemical use. The modular design allows for easy expansion and adaptation to specific needs.
