Technology Overview

VOC-SEP™ (PERVAPORATION & VAPOUR PERMEATION) systems can be developed to utilize either vacuum membrane distillation technology or pervaporation.

Vacuum Membrane
Distillation VMD in AQUA-SEP™

VMD systems utilize a membrane-based separation process for extracting low concentrations of volatile organic compounds (VOCs) from water by partial vaporization through a polymeric membrane. The membrane acts as a selective barrier between the feed in the liquid phase and the permeate in the vapor phase. The customized membrane allows only the selected desired component of the mixture to be transferred through it…..

Principle of Operation

VOC-SEP™ (PERVAPORATION & VAPOUR PERMEATION) systems utilize modules made from proprietary polymeric hollow fiber membranes. The hydrophobic (water repellent) nature of the membrane prevents the water from entering the pores of the membrane and allows only VOC’s to pass through.

VOC-SEP™ (PERVAPORATION & VAPOUR PERMEATION)units can be designed for batch or continuous operation depending on the volume of the process stream to be treated. The degree of separation is controlled by the membrane and fluid proprieties.

In continuous processes, multiple modules in series may be required to achieve the desired degree of separations.

A vacuum pump is used to maintain a vacuum on the permeate side of the module. Permeate vapors from the vacuum pump discharge are condensed in a condenser. gravida. Risus commodo viverra maecenas accumsan lacus vel facilisis.

However, distillation is extremely complicated when the concentration of the separating components are similar in the liquid and vapor phase, called the azeotropic point (e.g. Ethanol/Water or IPA/Water mixtures). Distillation alone cannot perform any further separation beyond the azeotropic point.

Pervaporation or Vapor Permeation
AZEO-SEP™ & VOC-SEP™

AZEO-SEP™ (PERVAPORATION & VAPOUR PERMEATION)systems use pervaporation for separation or purification of various liquid mixtures by partial vaporization through a non-porous membrane.

Principle of Operation
The membrane acts as a selective barrier between the two phases; the liquid phase feed and the vapor phase permeate. It allows the desired component(s) of the liquid feed to transfer through it by vaporization. The separation process is mainly due to polarity difference and not on the volatility difference of the components in the feed.
Limitations of Conventional Distillation
Distillation is a conventional fluid mixture separation technology that can separate components with different volatilities and markedly different boiling points (i.e. Benzene/Toluene mixture).

Commodity Filtration Systems Microfiltration

Micro-filtration and ultra-filtration are pressure-dependent processes. They remove dissolved solids and other substances from water to a lesser extent than Reverse Osmosis, yet with a high level of purity.

The membranes used in Micro-filtration have with a pore size of 0.1 – 10 micrometers (µm). The membranes used in Ultra-filtration have smaller pores varying in size from 0.001 – 0.1 (µm). This makes Micro-filtration excellent for the pre-treatment of surface water, sea water, and biologically tested municipal effluent.

Examples include:
Cold sterilisation of beverages and pharmaceutical
Clearing of fruit juice, wines and beer
Separation of bacteria from water (biological waste treatment)
Effluent Treatment
Separation of oil/water emulsions
Pre-treatment of water for nano-filtration or Reverse Osmosis
Solid-liquid separation for pharmacies or food industries
