DI-FUSION™ Cation Tank 14X47 + 3.6 Cu.Ft Purolite™ PFC100

When Ultra-Pure Water Depends on Precise Ion Control

Laboratories, pharmaceutical production lines, and electronics manufacturing facilities do not measure water quality in the same terms as residential systems. Conductivity, total dissolved solids, and ionic contamination must meet strict tolerances that change based on application and regulation. When a process requires deionized water, the cation stage is not optional, it is foundational. The DI-FUSION™ Cation Tank 14X47 addresses the first critical separation in high-purity water systems: removing dissolved cations before they reach downstream resin or mixed-bed polishing stages.

This tank is filled with 3.6 cubic feet of Purolite™ PFC100 cation exchange resin, a media specifically engineered for high-capacity ion removal in demanding environments. Unlike standard water softening resin, PFC100 targets the full spectrum of positively charged ions including calcium, magnesium, sodium, potassium, iron, manganese, and trace metals including lead, copper, zinc, and aluminum. Water enters the tank, flows through the resin bed, and exchanges cations for hydrogen ions. The result is water with drastically reduced cation load, protecting downstream stages from premature exhaustion and maintaining consistent TDS control across service cycles. Each tank is assembled in the USA using corrosion-resistant materials, precision inlet and outlet distribution, and bed support designed to prevent channeling under commercial flow rates. To explore how this cation stage fits into complete high-purity water production, read about commercial deionized (DI) water systems.

How Cation Exchange Protects the Entire Deionization System

In a two-bed or multi-stage deionization setup, the cation tank performs the first ion removal step. Water flows through the PFC100 resin bed, where dissolved cations are selectively exchanged for hydrogen ions. This reduces the cation load before water reaches the anion or mixed-bed stage, extending service life and improving regeneration efficiency. When cation exchange is performed correctly at this stage, downstream resin operates within design capacity, TDS breakthrough is minimized, and regeneration schedules become predictable.

The 14-inch by 47-inch tank dimensions are suited for moderate to high flow applications where contact time and exchange capacity must remain consistent. The 3.6 cubic feet of PFC100 resin provides the volume needed to handle fluctuating inlet water quality without compromising removal efficiency. Because cation resin can be regenerated using acid, this stage allows for cost-effective operation when managed within a structured maintenance schedule. Operators can monitor conductivity and TDS at multiple points within the system to determine when regeneration is required, ensuring that water quality remains within specification at all times. This tank integrates into existing DI systems or serves as the cation component in newly designed setups, pairing with anion tanks, mixed-bed polishing units, and carbon pretreatment vessels to form a complete high-purity solution. For businesses that depend on consistent water quality for pharmaceutical formulation, equipment cooling, or precision electronics rinsing, this cation stage is essential.

Pure Water Living - Precision, Reliability, and Long-Term Performance

When deionization is designed correctly, water quality becomes predictable. Each stage performs its designated function, TDS remains within tolerance, and operational costs stay manageable through efficient regeneration cycles. The DI-FUSION™ Cation Tank 14X47 provides the cation removal capacity that high-purity applications require, protecting downstream components and supporting the consistent performance your operation depends on. This is water treatment built on chemistry, not guesswork. Pure Water. Pure Trust.

Completing Your Water Strategy

While this cation tank provides selective ion removal, complete deionization requires coordination with anion and polishing stages.
