SLS · Technology
Solid-Liquid Separation
Some of the hardest separations are not chemical, they are physical. Tailings slurries, biological broths, fermentation streams, and process residues all need solids removed before downstream treatment. Petro Sep designs membrane-based and hybrid systems that concentrate solids and deliver clean filtrate without filter aids or rotating equipment.
What it solves
Performance you can size against.
The outcomes below come from commissioned systems and verified pilots, not theoretical limits. Every number is independently testable on your own feed.
- Solids concentration
- Up to 35 wt%
- Without polymeric flocculants.
- Filtrate clarity
- <5 NTU
- Direct feed to downstream RO or clean water reuse.
- Cake handling
- Mechanical or pneumatic discharge for direct disposal or further processing.
How it works
The working principle.
Crossflow or dynamic membrane filtration concentrates suspended solids while passing clarified filtrate. Modules are designed for high solids tolerance, with mechanical or air-assisted backwash to manage cake build-up. For challenging feeds, we combine SLS with chemical conditioning upstream and dewatering downstream.

Solid-Liquid Separation fits some sectors better than others. The industries below are where we have shipped multiple systems.
Have a feed that SLS
might fit?
We will pilot before we promise. Send us a sample and a target outcome. If the technology fits, we will tell you what to expect; if it does not, we will tell you that too.
