Membrane filtration is an advanced filtration technique distinguished by its ability to separate water from soluble substances such as oils, organic compounds, suspended solids and metals (particulate or ionic) using semi-permeable membranes. This technology is based on various membrane processes, each tailored to specific separation and purification needs.
Membrane filtration relies on the passage of water through a membrane, a semi-permeable material that allows certain substances to pass through while blocking others. The membranes used in these processes vary in pore size, ranging from a few hundred nanometers to several millimeters, which allows for the classification into four main types of membrane processes:
Microfiltration uses membranes with pore sizes between 0.1 and 10 micrometers (μm). It is primarily used to remove suspended particles, algae, and bacteria from water. This process is commonly employed in wastewater treatment.
Ultrafiltration employs membranes with pore sizes between 1 and 100 nanometers (nm). This process is effective for separating proteins, viruses, and colloidal particles from water. UF is often used in wastewater treatment.
Nanofiltration uses membranes with pore sizes between 1 and 10 nanometers. This intermediate process between UF and RO allows for the separation of multivalent ions and small organic molecules. NF is commonly used for potable water production.
Reverse Osmosis is the most effective filtration technique. It can remove almost all contaminants, including dissolved salts and organic molecules. RO is primarily used for seawater desalination and the production of high-purity mineral water.
Membrane filtration are used in a wide range of applications :
Membrane filtration is essential in desalination, where Reverse Osmosis (RO) is used to remove salts and other contaminants from seawater, producing potable fresh water.
MF and UF processes are commonly used to treat wastewater, removing solid particles and micro-organisms.
NF and RO are used to purify water intended for human consumption, guaranteeing high quality and optimum health safety.

GRP (Glass Reinforced Polyester) is a composite material combining polyester resin and glass fibers. This combination gives it high mechanical strength, excellent durability, and remarkable chemical resistance.
GRP (Glass Reinforced Polyester) is a composite material offering an exceptional combination of lightness, mechanical strength, and durability. It is distinguished by its high resistance to corrosion, chemicals, and extreme environmental conditions, making it ideal for a wide range of industrial applications. In addition, its design flexibility allows for the manufacture of custom structures, optimizing the performance and longevity of equipment.
GRP (Glass Reinforced Polyester) cannot be recycled in the same way as traditional plastics. Due to its composite composition—a polymer matrix reinforced with glass fibers—conventional mechanical recycling is difficult. However, there are specialized processes for recovering end-of-life materials, including energy recovery or grinding techniques and reuse in secondary applications (fillers, construction materials, etc.). In addition, research is underway to develop more sustainable recycling methods for composites. GCER remains attentive to these technological developments in order to integrate environmentally friendly solutions into its processes.

A membrane housing is an essential component in membrane filtration systems, used to protect, maintain, and optimize the functioning of filtration membranes. This advanced technology effectively separates unwanted substances in liquids, such as oils, suspended solids, organic matter, and metals, using semi-permeable membranes. In these filtration systems, the membrane housing performs a crucial role in ensuring smooth and controlled liquid flow while maintaining stable internal pressure. It also prevents external contamination, thereby guaranteeing the integrity of the membranes and the efficiency of the filtration process.
Membrane housing are used in many industrial sectors, including : • Wastewater and drinking water treatment : used in wastewater treatment and desalination plants to ensure watertightness and durability in corrosive environments. • Chemical industry : to provide an effective barrier against aggressive chemicals and prevent leaks. • Pharmaceutical industry : to maintain sterile environments and control fluid flows safely. • Agri-food : to ensure hygiene, product safety, and ease of cleaning. • Energy and environment : used in industrial facilities and pollution control systems requiring high mechanical and chemical resistance. • Petrochemical industry : for applications with demanding pressure, temperature, and corrosion resistance requirements.
The membrane housing is used because it offers many important advantages in a filtration system : • Membrane protection: It protects the filtration membranes from external contaminants, extending their service life and ensuring their performance. • Pressure control: It regulates the pressure within the filtration system, which is essential for optimal membrane operation. • Effective separation: The membrane housing ensures high-precision separation of unwanted substances, enabling high levels of liquid purification. • Reliability and safety: Membrane housings are designed to withstand high pressures and demanding environments, providing a robust and durable solution.
Maintaining a membrane housing is relatively simple, but it is essential to ensure its longevity and performance : • Regular inspection : check the condition of the membrane and seals frequently for cracks or wear. • Cleaning components : clean the internal surfaces properly to prevent the accumulation of contaminants that could interfere with filtration. • Membrane replacement : the membrane must be replaced when signs of wear are visible or if it no longer guarantees a perfect seal. • Pressure control system checks : ensure that the pressure regulation mechanism is working properly to prevent dangerous variations.
