Suspended Solids Separation System

Tubular Membrane Filter (TMF™) Modules

render pic 2.jpg

A processing skid, with Tubular Membrane Filters, designed to target Total Suspended Solids as a ultra-filtration. Offering superior solids removal efficiency, higher flux and reduced system footprint, where a fluid containing solids in suspension, such as industrial pre-treated wastewater, flows through the membrane tubes at high velocity to maintain turbulent flow.


Suitable for applications including:

  • Heavy Metal Removal from Plating or Printed Circuit Processes

  • Semiconductor

  • Dewatering Oil/Water Emulsions

  • Metal processing Coolant/Glycol cleaning

  • Photovoltaic process water

  • Pre RO & RO Reclaim (Power, Steel/Iron, Brine Recycling

  • Fluoride Removal

  • High Solids WW

  • Zero Liquid Discharge (ZLD) Systems


Capable of operating in pH range of 0-14 standard units, these high performing filter modules are resistant to a broad spectrum of corrosive chemicals and reagents.

The system operates as a batch process at typical operating pressures of 20–80 psi, clean fluid is forced through the pores of the membrane, while suspended particulates remain in the retentate stream. The turbulent flow of the retentate stream prevents the build-up of particles on the inner surface of the membrane tube, prolonging filter life.


The design and performance of the large bore tubular design may eliminate the need for pre-filtration and should routinely handle high solids levels up to 5% by weight and have long service life in excess of 20 years.

Typically, pilot feasibility tests are needed to determine the actual TMF module performance under real operating conditions. We can conduct small scale tests requiring only small water samples to design a system specific to your application needs.

Tubular Membrane Filter Modules provide a cost effective alternative to dosing chemicals and changing filter bags or cartridge filters on a daily basis. TMF is a filtration technology that can handle process streams with high oil and solids concentration that presents a challenge to other membrane based technologies

The modules contain a number of permeable sintered particle tubes, specifically designed to allow fluids to pass through while leaving behind oils and suspended solids

Typical Applications

Metal working coolant recovery


Used Coolant has a high concentration of oils and metal particles

Coolant after use collects oils and particles from the process


Specifically designed to remove Total Suspended Solids from glycol coolant fluid used in machine shops and metal forming processes. Used coolant accumulates large amounts of oils and small particles or metal and other suspended matter, which, if left in the coolant and re-used lead to premature wear of parts and tooling and more frequent maintenance.


The fluid is pumped through the membrane tubes at high velocity to maintain turbulent flow through a 0.05 micron module. The resulting recovered coolant had no residual oils or metal particles and no odor.


Refractory testing revealed the recovered coolant to be as concentrated as new coolant.

Recovered Coolant

The recovered coolant through TSS process tested at same concentration of Glycol as new product, making this a feasible technology to reduce waste.

Starch separation from bean processing

Installed to target Total Suspended Solids from wastewater fluid resulting from cooking beans, the liquid contains large amount of starches which, if left untreated and disposed, will decompose and generate gases in the sewer system. The fluid is pumped through the membrane tubes at high velocity to maintain turbulent flow.

With a 0.05 micron module even the coloration was removed and prepared the waste flow to be disposed of safely.
