Membrane Technologies

Reverse Osmosis Technology

Reverse osmosis (RO) stands out as one of the most reliable and effective water treatment technologies. In this system, raw water is forced through the microscopic pores of semi-permeable membranes using high pressure. These pores allow only pure water molecules to pass through, while salts, heavy metals, bacteria, viruses, pesticides, and other harmful contaminants are retained by the membrane and removed from the system as concentrated water.

Ters osmoz sistemleri, filtrasyon teknolojilerine kıyasla çok daha yüksek bir su kalitesi elde edilmesini sağlar. Sistemlerimizin gövde yapısı paslanmaz çelik ya da epoksi kaplamalı karbon çelikten üretilebilmekte; bu sayede uzun ömürlü, dayanıklı ve hijyenik bir çözüm sunulmaktadır. Ters osmoz membranları sayesinde çözünmüş tuzların, inorganik ve yüksek molekül ağırlıklı organik maddelerin %90 ila %99.5 oranında giderimi sağlanır. Kuyu, deniz, yüzey suyu gibi farklı kaynaklardan alınan sular, bu sistemle yüksek saflıkta suya dönüştürülür.

MBR Technology – Membrane Bioreactor

MBR (Membrane BioReactor) is a highly efficient advanced treatment system that integrates traditional biological treatment processes with membrane technology. This technology uses microfiltration (MF) or ultrafiltration (UF) membranes after the biological reactor to separate solids and liquids, replacing traditional sedimentation tanks. This saves space and produces effluent of the desired quality, free of microorganisms and particles.

MBR systems have a more compact structure than conventional systems. They do not require large areas such as aeration and sedimentation tanks, making them ideal solutions for projects with limited space. They also offer high chemical oxygen demand (COD) removal performance for wastewater with low biodegradability. The recycled water is reintroduced into the biological treatment process, along with the waste separated from the membranes through various backwash and chemical cleaning processes.

Areas of Use:

  • Grey water treatment systems

  • Domestic and industrial wastewater treatment

  • Regions with discharge limits to water basins

  • Recycling projects and irrigation water production

  • Existing treatment plants that need capacity expansion

  • Reuse in processes with high water consumption

Nanofiltration Technology

Nanofiltration systems are advanced, high-pressure filtration systems with membrane pore diameters of 0.001 microns. This technology safely removes bacteria, viruses, cysts, and organic compounds from water. It also optimizes the chemical properties of water by lowering alkalinity. However, this can cause the water leaving the system to become corrosive, so water analysis is essential before application.

Nanofiltration systems are an effective solution not only for microbiological safety but also for reducing color, hardness, and chemical loads in water. These features make them used in many industries to improve water quality and reduce energy costs. These systems also play a critical role in desalination (salt removal) and wastewater recycling projects.

Areas of Use:

  • Food and beverage industry

  • Treatment of groundwater and surface water

  • Production lines that require clean and soft water supply

  • Desalination and recovery projects

Ultrafiltration Technology

Ultrafiltration (UF) systems are a membrane-based physical separation technology and operate using specialized filters with a pore diameter of 0.01 microns. These systems remove colloids, silt, bacteria, viruses, and organic matter from water. This method, which does not require the use of chemicals, offers a treatment process that is both economical and environmentally friendly.

Ultrafiltration systems provide high performance, particularly in the pretreatment stages of drinking water, source water, and production processes. When used before reverse osmosis (RO) systems, they increase system efficiency by extending the life of the primary membranes. They are also widely preferred in industrial solid-liquid separation applications.

Areas of Use:

  • Food and beverage industry

  • Car wash and laundry water recovery

  • Chemical process waters

  • Reverse osmosis pretreatment

  • Process waters free from microorganisms

  • Industrial filtration and recovery applications
