One Eye Industries · Magnetic Filtration

The damage you cannot see,
in the fluid you cannot clean.

Below about four microns, ferrous wear debris stops behaving like a solid and starts behaving like part of the fluid. Gravity does not remove it. Settling tanks do not remove it. Centrifuges do not remove it. Media filters cannot remove it without stripping out the barite you paid for. It circulates, and it keeps cutting.

STAGE 01

The Silent Killer

Why the fine fraction never settles out, whatever you do to the tank.

48 days
for a 2 µm particle to fall two metres. The system turns over every 28 minutes.
STAGE 02

The Blind Spot

Seven stages of solids control, and the damaging fraction walks through all of them.

98% / 2%
of the metallic wear removed, and left behind. Both true at once.
STAGE 03

Breaking the Cycle

What high-gradient magnetic filtration does about it, and what that is worth.

97%
of ferrous debris captured from the fluid passing through the unit, per pass.

Conventional solids control removes 98% of the metallic wear
and leaves the 2% that does the damage.
Mass scales with the cube of diameter, so one 100 micron chip outweighs eight million half-micron particles. The shakers and cyclones take nearly all of that mass out, the returns look clean, and everyone concludes the system is working. Metal is not worn away by mass. It is worn by the number of hard particles small enough to enter a running clearance.
Basis. Stokes' law terminal velocity at Reynolds number below 1; Stokes–Einstein diffusion for Brownian displacement; magnetic body force balanced against Stokes drag. Steel 7,800 kg/m³, mud 1,200 kg/m³ at 30 cP and 60 °C. Cascade order per Rabia (2001) and Hossain & Al-Majed (2015), validated against a generic P&ID. Cut points are industry-typical ranges and vary by make, screen, feed and operating condition. Counts weighted to a wear-debris size distribution of d−1.73; the defensible range is 1.5 to 3 and the answer moves materially across it. Capture per pass is a property of the unit, not of the rig. Performance and financial figures are vendor field and demonstration data, representative and illustrative, to be confirmed by field data. Not a guaranteed result.
