MB/MBA mixed bed

Product catalog summary

Overview: The document details the specifications and applications of an Automatic Mixed-bed plant, specifically the D2B-40A/1 model, designed for demineralizing water with extremely low salt content. It is suitable for industries such as pharmaceuticals, electronics, hospitals, and power stations.

Applications: The plant is applicable for polishing demineralized water from automatic two-column or reverse osmosis plants and for producing high-quality water directly from waterworks.

Mixed Bed Principle: Utilizes a mixture of cation and anion exchangers regenerated with hydrochloric acid and sodium hydroxide to produce demineralized water with low conductivity.

Regeneration Process: Involves separation and regeneration of exchangers with acid and base, followed by mixing with compressed air. The process takes 3.5 to 4 hours.

Plant Design: Features a resin tank treated with high-density polyethylene, plastic pipes, and automatic valves. The dielectric strength is approximately 21 kV/mm.

Control Panel: Includes a 12 V electronic control panel with a conductivity meter, control, and program sections. It has battery backup and remote alarm output.

Quality Control: Conductivity meter indicates water quality in microSiemens (µS/cm). An adjustable alarm can transmit regeneration impulses.

Program Facilities: Offers options for timer, meter, or quality control with sixteen time-adjusted regeneration cycles. Operational conditions are monitored via LEDs.

Duplex Operation: Allows continuous operation with two plants, ensuring one is always in service while the other regenerates.

Capacity: The plant has a large capacity, calculated by dividing basic capacity by the total salt content of feedwater.

Quality and Polishing: Achieves conductivities as low as 0.1 µS/cm at 10°C with low carbonic acid content. Silica content reduction requires heated regeneration water.

Waterworks Water Quality: Produces demineralized water with lower conductivities than two-column or reverse osmosis plants using ordinary clean waterworks water.

Accessories: Includes acid and caustic drawn by ejectors, with neutralization of waste water according to regulations.

Manual and Automatic Options: Available in both manual and automatic regeneration versions.

Specifications: Detailed specifications include flow rates, basic capacity, regenerant consumption, and required space dimensions for various modules (MB/MBA 40 to MB/MBA 1800).
