DESCRIPTION

Product description：

Designed for commercial or light-industrial water treatment systems, this 20″ Big-Blue format CTO cartridge uses compressed carbon block media to handle high flow rates while maintaining effective chlorine, taste, and odor removal. Its robust build and high dirt capacity make it suitable for demanding water supply environments.

Carbon Block Filter：

Carbon Block also known as CTO Filters, is made from activated carbon. Activated carbon is carbon that has been treated with oxygen to make it porous, allowing for a larger surface are for chemical reactions to occur. The water passes through the filter allowing the organic materials and chlorine to effectivly bond with the carbon molecules, thus removing them from the water.

Carbon Block (CTO) filters effectiveness depends on the flow rate and contact time with the water. If the flow rate is very high their efficiency could drop to as low as 0% but if the flow rate is slow their efficiency can even exceed those of various different carbon forms. It also has a 5 micron filter ability.

Carbon Block is used to absorb natural organic compounds and synthetic organic chemicals which affect the colour, taste and odour in drinking water.

Key Benefits:

Big-Blue large format supports high flow and high volume water usage.
5 micron filtration with activated carbon ensures chemical and odor removal.
Durable PP end-caps and shell for long service life and stability.
Low pressure drop even under heavy flow, ensuring system efficiency.
Compatible with standard commercial housings — easy to install and replace.

Where Can You Use It?

Commercial kitchens, hotels, restaurants water supply systems
Light-industrial water pre-treatment before RO or other purification
High-flow drinking water stations or dispensers
Utility water filtration in small industrial facilities
Bulk supply for system integrators and water treatment contractors
