YUTANK vertical flow sedimentation tank, also known as cyclone sewage collector, adopts circular vertical structure to settle fish manure and residual feed. Small footprint, easy installation, intercept suspended particles, reduce subsequent equipment load and realize solid-water separation for RAS aquaculture.
Vertical Flow Sedimentation Tank, also named Vertical Sedimentation Tank or Cyclone Sewage Collector, is essential front-end pretreatment equipment for fish pond aquaculture. It is specially used to purify breeding water containing residual feed, fish manure and suspended impurities.
With a round planar tank design, it realizes vertical downward and upward circulating water flow, completes solid-liquid separation through gravity sedimentation and suspension interception, and stably improves inlet water quality for subsequent RAS water treatment systems.
Water containing fish manure and residual feed flows into the tank from the central inlet pipe from top to bottom. An umbrella-shaped baffle at the bottom distributes the water evenly inside the tank, then the water rises slowly along the entire cross-section.
Suspended particles sink into the conical sludge hopper at the tank bottom and form a suspension layer to intercept rising fine impurities. The clarified clean water overflows out through the peripheral weir. A baffle and scum tank are installed in front of the weir to trap floating slag and ensure stable outlet water quality.
A sludge discharge pipe is arranged on one side of the tank wall; sludge is discharged regularly by static water pressure. In the vertical flow tank, the water flow direction is opposite to the particle settling direction. Particles with the same rising speed and settling speed form a stably suspended filtering layer, achieving efficient interception and filtration of tiny impurities.
Small Footprint, One Tank Matching One Fish Pond
Each fish pond can be equipped with one independent small vertical flow sedimentation tank, compact structure and covers minimal land space.
Reduce Load of Subsequent Water Treatment Equipment
Effectively intercepts and settles fish manure, residual bait and suspended solids in advance, greatly lowering the filtration and biochemical burden of downstream equipment such as microfilters and biofilters.
Solid Waste and Reclaimed Water Separation
Realizes separate diversion of solid waste and recyclable breeding water, maximizes gravity sedimentation efficiency and optimizes water recycling rate.
Simple and Convenient Installation
Integrated structural design, no complicated civil engineering required, easy on-site assembly and layout arrangement.
Particle Interception, Filtration and Regular Sludge Discharge
The internal suspension layer automatically intercepts rising fine particles; sludge is discharged regularly by static pressure, keeping long-term stable water purification performance.

It is also called cyclone sewage collector, used for front-end pretreatment of fish ponds to settle residual feed, fish manure and suspended impurities by vertical water flow gravity sedimentation.
No. It has a compact round structure, one small tank matched for each fish pond, with very small footprint.
It separates solid waste in advance, reduces the load of subsequent water treatment equipment and improves overall system operating efficiency.
No, the structure is simple, easy to install and put into use quickly without complex civil construction.
Sludge is discharged regularly through the sludge discharge pipe by static water pressure, and the internal suspension layer can automatically intercept fine particles.
