High-Efficiency Vortex Grit Removal System
Advanced Grit Separation Technology for Municipal & Industrial Pre-treatment.
- Item 1:Superior Separation: Removes 95% of grit particles ≥ 0.2mm.
- Item 2: Corrosion Resistant: Full SUS304 / 316L stainless steel internals.
- Item 3: Energy Efficient: Low-speed paddle design minimizes power consumption.
The Industry Challenge:
Inorganic grit (sand, gravel, cinder) causes severe abrasion to pumps, pipes, and sludge dewatering equipment. If not removed effectively in the pre-treatment stage, it accumulates in digestion tanks, reducing active volume by up to 30% and causing costly maintenance shutdowns.
The Feiran EP Solution:
Our Vortex Grit Chamber utilizes the Coanda effect and centrifugal force to separate grit from organic matter. The paddle mixer maintains a constant rotational velocity, ensuring that organic solids remain suspended while heavy grit settles into the central hopper. This guarantees clean grit output and maximum protection for your downstream assets.

Q1: How does the Vortex system differ from an Aerated Grit Chamber?
A: Vortex systems are more compact, require less energy (no blowers needed), and release fewer odors since there is no air turbulence to strip VOCs into the atmosphere.
Q2: Can it handle varying flow rates?
A: Yes. The Feiran EP Vortex Grit Trap is designed to maintain high separation efficiency across a wide range of hydraulic loads, making it ideal for plants with fluctuating peak flows.
Q3: What equipment is usually paired with this system?
A: It is typically paired with a Grit Classifier or Sand Washer. The grit pump extracts the slurry from the hopper and feeds it to the classifier for final dewatering and discharge.
