JCAFM-S Inorganic Nano-Modified Glass Filter Media | 1-Micron Precision Filtration

JCAFM inorganic nano-modified filter media

Product

JCAFM-S Inorganic Nano-Modified Filter Media

Application

Replaces conventional media such as quartz sand, glass sand, anthracite and activated carbon in all types of media filtration processes. Under specific operating conditions it can also optimize or even simplify existing membrane filtration configurations.

Function

Effectively removes suspended particles, suspended oil and heavy metals from water bodies

Material

Green glass substrate with optimized particle shape and an activated surface design

Features

Biofouling-resistant and self-cleaning, with a long service life and stable filtration performance. Outstanding filtration accuracy, achieving fine filtration down to 1 micron

JCAFM-S Media Grades

JCAFM‑0 (0.25‑0.5mm)

For fine filtration, with >98% filtration efficiency at the 1-micron level. Effectively removes suspended oil from oily wastewater.

JCAFM‑1(0.4‑0.8mm)

The primary filtration medium, with >97% filtration efficiency at the 5-micron level. Combined with flocculation, filtration performance can be extended to sub-micron.

JCAFM‑2(0.7‑2.0mm)

Normally used as a support layer, and in certain special applications as the main filtration layer. Overall performance is superior to conventional media of the same grade.

JCAFM‑3(2.0‑4.0mm)

Used as a support layer to cover the bottom distributor of the filter and ensure proper hydraulic water flow distribution during backwashing.

Technical Highlights

JCAFM-0 achieves over 98% filtration efficiency for particles of 1 micron and above, while JCAFM-1 reaches over 97% efficiency for particles of 5 microns and above — and with flocculation its filtration accuracy can be pushed further into the sub-micron range.
The nano-activated surface, combined with a specific hydrophilic–oleophobic structure, effectively removes organics and suspended oil from water.
Biological resistance greatly reduces the likelihood of media-bed caking and wormhole channelling, helping the filtration system run stably over the long term and limiting the efficiency loss caused by bed anomalies.
Stable desorption performance delivers predictable, repeatable and highly consistent filtration results. Under proper operating conditions the media provides a long, durable service life.
Backwashing requires less intensity and no additional air-scouring step, effectively reducing backwash water consumption and overall operating costs compared with conventional media.

FEATURES

High Strength · Wear and Impact Resistant

Mohs hardness >7 with excellent mechanical strength, resisting high-velocity water impact.

Low Attrition · Long-Term Stability

After 100 hours of backwashing at 50% bed expansion, attrition remains below 1%.

Long Life · Economical and Energy Saving

A design life of up to 10 years matches the equipment service cycle and reduces media replacement frequency.

1’ Biofouling-Resistant Surface

Water molecules and dissolved oxygen

are converted into free radicals on the JCAFM surface (catalytic reaction)

This inhibits biological scaling and protects JCAFM from bacterial proliferation.

Suppresses bacterial growth and reduces the likelihood of biofilm formation
The surface ionization layer keeps contaminants from contacting the media itself, improving backwash desorption
Reduces performance loss caused by microbial attachment and keeps the media clean over the long term

2’ Mesoporous, Ultra-Large Surface Area

JCAFM-1 = 50.000 m² / 1000 kg

A high specific-surface-area substrate with excellent surface filtration capability captures very fine particles
Optimized particle shape and sphericity provide excellent hydraulic characteristics
A molecular-sieve effect delivers markedly better filtration and adsorption than conventional media such as quartz sand and glass sand

3’ High-Precision Oil Removal

Strong Negative Surface Charge

Provides stable, reliable filtration performance and is effective at removing suspended solids, positively charged particles and heavy metals such as iron, manganese and arsenic.
