AQUARIUM OSMOSIS DEMI RESIN CARTRIDGES MB400 20

Cartridge set for the RO4 filter for aquarium use

The set has been prepared for use in reverse osmosis systems used in aquarium keeping. The cartridges work with systems in which the water is first pre-cleaned, then directed through the osmotic membrane, and finally additionally polished by a demineralizing cartridge.

This water filtration system effectively limits the presence of mechanical and chemical contaminants and also removes remaining ions from the water after the membrane. As a result, the set performs well wherever water quality is of key importance.

Set contents

• FCPS5 – sediment cartridge made of polypropylene nonwoven fabric
• FCCBL – Aquafilter activated carbon cartridge
• FCEB10-DEMI – cartridge with MB400 resin for water demineralization

Cartridge characteristics

FCPS5 – sediment cartridge

This is a mechanical cartridge responsible for trapping solid contaminants present in the feed water. It is an important protective stage for the other system components, including the carbon cartridge and the installation operating in a reverse osmosis filter setup.

• Type: sediment (mechanical)
• Material: polypropylene nonwoven fabric
• Function: retains mechanical contaminants down to 5 μm, such as sand, silt, and rust
• Construction: filter density increases toward the core

FCCBL – carbon cartridge

The activated carbon cartridge improves water quality on a chemical and organoleptic level. It is an essential element of any system where effective water treatment before further purification stages matters.

• Type: sintered activated carbon
• Function: removes chlorine and organic compounds and eliminates bad taste and odor from the water
• Advantages: low pressure drop and high absorption capacity

FCEB10-DEMI – demineralizing cartridge with MB400 resin

This is the final polishing stage for water after the RO membrane. The cartridge with MB400 resin is designed to remove remaining ions from the water, making it suitable where demineralized water of very high purity is required.

• Type: demineralization
• Application: demineralizing bed in a 10-inch housing
• Function: removes all ions from the water
• Construction: disassemblable housing, reusable
• Practical use: water polishing after the membrane in RO systems, marine aquarium keeping, laboratory research

How this set works in the filtration system

The set creates a coherent operating system for a water filter used in aquarium keeping. In the first step, the FCPS5 cartridge captures mechanical impurities. Next, the FCCBL cartridge reduces chlorine and organic compounds, improving water parameters before further purification. The final stage is the FCEB10-DEMI, which is used to polish water after the osmotic membrane and removes all ions from the water.

This combination is especially useful when the standard operation of the RO membrane is not yet the final stage and additional water purification to a very high level of purity is needed.

Typical application

The set is used in professional aquarium keeping, especially marine aquariums, as well as in laboratories for preparing water with zero or near-zero conductivity. The cartridges ensure high water quality, essential in specialized applications.
