Water Treatment Solutions for Oil & Gas Filtration - Produced & Frac Flowback Water Treatment

Discharge and re-injection of produced water from oil/gas production is becoming increasingly challenging for the oil producers as the world’s oil wells mature and the water cut increases.

With LiqTech’s revolutionary SiC ceramic membrane technology, it has never been easier to meet these tightening standards and requirements for produced water and flow back water (fracking).

One-Step Filtration with LiqTech's SiC membranes

Due to the unique hydrophilic properties of Silicon Carbide, it is possible to obtain higher water fluxes on LiqTech’s SiC-based ceramic membranes than any other membrane material.

Continuous process flux for oil/water separation is recorded between 200 – 2000 L/(m²h)! – depending on the oil type. Removal of oil and TSS to below 1 ppm is possible at very high flux rates.

This means that our filtration solution has become a viable alternative to hydrocyclones, induced gas flotations units, micro-flotation, and walnut shell filters. 

LiqTech’s filtration solution replaces before mentioned conventional solutions with a one-step-filtration system based on LiqTech’s SiC membranes. We can meet discharge levels for oil content, where conventional technologies cannot. 

LiqTech offers a market proven water treatment system for produced water and flow back water (fracking) both onshore and offshore.

SiC Ceramic Membrane Properties

Our revolutionary silicon carbide ceramic membranes will provide you with a future proof water treatment solution for tertiary treatment of produced water.

  • pH range: 0 to 14
  • Abrasion-resistant
  • Temperature: Up to 800°C in air
  • Solvents: Completely stable
  • Oxidizers: Any concentration
  • Permeability: Highest for any membrane material

i.e. the highest flux and most robust properties for any membrane material

= Fit for Oil & Gas

  • SiC membrane surface is very hydrophilic = oleophobic, thus repelling oil
  • SiC membrane surface charge is negative at most pH-values, oil droplets are typically negative charged, thus repelled from the membrane surface
  • Weight, footprint, and energy reduction due to higher permeability of SiC membranes
  • Chemical resistance in order to ensure efficient cleaning of membranes for worst-case scenarios (severe scaling)
