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-based 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 Membrane Properties

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

  • pH range: 1 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)
