Q-ALU™

Calcium Sulfite

Calcium sulfite with improved reactivity thanks to special particle shape

summary

Features

Tateho’s Q-ALU™ calcium sulfite is characterized by a special particle shape that secures compatibility between high reactivity and ease of handling, with optimum conditions for removing residual free chlorine in tap water.
Q-ALU™ is used as a water purification dechlorinator or a delayed reducing agent.
It is supplied in various granulation type products as well.

High-Reactivity Calcium Sulfite

1. With its complexly shaped particles, Q-ALU™ has large specific surface areas, thus a high per-weight chlorine-treating capability.
2. The reduction of its specific surface areas after granulation can be suppressed, because of it’s large specific surface areas even though it's particle size is large.

Usages

• Dechlorinator used in water purification units
• Delayed reducing agent
