SEPAREL® PF Series SEPAREL® PF Series

The SEPAREL PF series removes dissolved gases in water through a tube-shaped gas permeable membrane composed of polytetrafluoroethylene (PTFE). Gasses dissolved in water flow through the tube and are removed due to the pressure difference of the gases inside and outside of the tube, thus creating a vacuum outside of the tube. This video explains how the PF series works.

SEPAREL® EF Series SEPAREL® EF Series

The SEPAREL EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. Also, a lower pressure drop means that larger modules can be used. This video explains how the EF series works.

Small SEPAREL® EF Series Small SEPAREL® EF Series

The small SEPAREL EF series is optimized to remove dissolved gases in water applications with smaller flow rates. The EF series uses external flow which allows water to randomly flow over the hollow fibers and, in turn, contact dissolved gases more frequently. Therefore, desgassing performance with the EF series is higher than the PF series which utilizes internal flow. This video explains how the EF series works.

WATER MEMBRANES

 

Water membranes are widely used in the water treatment processes. They have become a fundamental player in separation technology because of the fact that they require no additional chemicals and their relatively low energy requirements.

Water membranes have been applied during the extraction of produced water, treatment of waste/sewage water and processing of surface water all with huge success levels. Conventional water treatment techniques are over time incorporating in their processes the use on water membranes. Commercialization of membranes was first done in the 1970s and 1980s.

Membrane technology is chiefly based on the presence of pores on the membranes that make them semi-permeable. The simple principle on which water membranes work is such that the semi-permeability of water membranes ensures that only water is allowed to pass through a specific membrane while trapping unwanted particles and substances.

In both microfiltration and ultra filtration, membranes provide an effective barrier for arresting suspended solids in water.

To aid substances to penetrate across a semi-permeable membrane the following steps are undertaken: Electric potential introduction, high pressure application and ensuring that the concentration gradient on both sides of the membrane is maintained. The surface area of the membrane also determines the efficiency of the membrane in use.

The only drawback on water membranes is that they cannot remove substances that are actually dissolved in the water such as phosphorus, nitrates and heavy metal ions. The following are categories of membranes: Microfiltration (MF), Ultra filtration (UF), Reverse osmosis (RO), and Nanofiltration (NF) membranes

Ultra filtration membranes employ polymer technology with chemically created microscopic pores that trap dissolved substances therefore eliminating the possible use of any coagulants.
