    Power Plant Uses Membrane Contactors To Remove CO2 From Water

    A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO2 inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO2 to reduce the load on the equipment and improve the water quality.

  • Santa Barbara, Curaçao Desalination Plant: Six Years Of Operation Of LG Chem Thin Film Nanocomposite (TFN) SWRO Membrane
    Santa Barbara, Curaçao Desalination Plant: Six Years Of Operation Of LG Chem Thin Film Nanocomposite (TFN) SWRO Membrane

    The Santa Barbara desalination plant located in the south-eastern part of Curaçao provides drinking water to about half of the population of this Caribbean island. With an average precipitation of approximately 500 mm, rainwater is the only natural source of freshwater in the island. Government efforts to address the water shortage problem date back to the 20s of the last century. Initially based on evaporation, the seawater desalination evolved into the reverse osmosis technology in the 90s. After several years of experimenting with RO, Aqualectra, the municipal supplier of potable water and electricity for Curaçao, took the decision to move forward with this technology and in 2003 started a project to build a SWRO desalination plant.

Savings Helps MABRs Gain Traction In Municipalities
Savings Helps MABRs Gain Traction In Municipalities

An MABR is essentially a biological wastewater treatment process that utilizes seemingly passive aeration through oxygen-permeable membranes. Oxygen transfer through the MABR membranes is diffusion based: driven by concentration differences such that oxygen passes from air at atmospheric pressure into water at a higher hydrostatic pressure. This oxygen transfer mechanism, wherein air is supplied to the process at very low pressure, is the reason MABRs have significantly lower energy consumption compared to other wastewater treatment processes, such as conventional activated sludge (CAS), that utilize diffusers. This energy savings is one of the key reasons MABRs are gaining traction in the municipal wastewater industry.

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.
