Filtration charges

Filter media charges for sand filters in aquaculture are designed to enhance water filtration efficiency by trapping suspended solids, organic matter, and particles. These media, typically composed of sand, gravel, or other materials with a specific grain size (such as glass), are essential for maintaining water quality in Recirculating Aquaculture Systems (RAS).

The media charge plays a key role in particle removal, helping to reduce the organic load and improve the performance of downstream biofilters. Depending on the aquaculture system’s needs, the media charge can be customized for optimal filtration, ensuring that aquaculture farms, shrimp farms, and hatcheries maintain clean and clear water.

Key Features:

Effective particle removal: Captures both fine and coarse particles from the water.
Durability: Long-lasting media that can withstand continuous use in demanding aquaculture environments.
Improved water quality: Helps reduce organic buildup and supports better biological filtration.

Special Cases:

Specific media are used for biological filtration of water (zeolite, clay, pumice).
Filters can be filled with media that have chemical activity (activated carbon, clay, peat, coral sand, sulfur) to treat specific water parameters.

Subcategories

Zéolite

Zeolite is a natural or synthetic aluminosilicate mineral formed by the weathering of volcanic rocks in an alkaline environment. Its microporous crystalline structure gives it a very high cation exchange capacity and a large specific surface area. These properties make it an excellent filtering material for aquaculture.
Filtration Silica

Filtration silica (or silica filter sand) is a natural granular material commonly used in water treatment systems — particularly in aquaculture and aquariology.
Glass Filter Media

Glass filter media is an eco-friendly material made from recycled and polished glass. Its smooth, non-porous surface prevents bacterial growth and reduces filter clogging. More efficient than traditional sand, it provides better filtration quality, water savings during backwashing, and a longer lifespan. In aquaculture and water treatment, glass media ensures clear, healthy, and stable water.
Lit fluidisé

MBBR (Moving Bed Biofilm Reactor) media is a floating plastic support for biological water filtration. It allows beneficial bacteria to grow as a biofilm and efficiently break down organic compounds and nitrogen (ammonia, nitrites). Used in aquaculture and water treatment, it provides stable, self-maintaining purification with minimal maintenance.
Activated carbon

Activated carbon is a natural carbon-based material known for its exceptional ability to adsorb impurities from water. Its microporous structure effectively captures organic compounds, chemical residues, and unwanted odors. In aquaculture, it helps maintain clean and healthy water, promoting fish well-being and growth.
