Commercial and Industrial Ultrafiltration UF System

Industrial ultrafiltration (UF) systems are a water purification process, during which water passes through a semi-permeable membrane for filtration. As a result, suspended solids and high-molecular-weight solutes remain on one side of the membrane, known as the retained side, while water and low-molecular-weight solutes pass through the membrane to the permeation side.

Therefore, the pore size range of ultrafiltration membranes is between 0.1 and 0.01 micrometers. However, "molecular weight cut-off value" (MWCO) has now become one of the best ways to describe ultrafiltration membranes. So, MWCO refers to the molecular weight at which 90% of high-molecular solutes cannot pass through the membrane. Therefore, the filtration range of ultrafiltration lies between microfiltration and nanofiltration.

What is the role of ultrafiltration technology in water treatment?

Modern membrane technology began in the late 1990s when polymer membrane chemistry and treatment technologies were applied to membrane manufacturing. As a result, these new materials and manufacturing methods have made ultrafiltration an efficient and competitive water treatment process.

What are the advantages of industrial ultrafiltration systems?

Industrial ultrafiltration systems (UF systems) technology can complete more work while reducing the occupied space by 50%. That's why ultrafiltration pretreatment is selected as the standard configuration for all Huaxin  high-end seawater and brackish water modular desalination devices.

Ultrafiltration (UF) pretreatment technology can extend the service life of reverse osmosis membranes in water bodies with high sedimentation index (SDI). At the same time, this method has a lower investment cost, lower operating cost, no need for coagulants, and very little use of chemicals.

Stainless steel skid-mounted ultrafiltration system devices are suitable for various applications. For example, they can be used for reverse osmosis (RO) pretreatment, surface water clarification, high SDI groundwater treatment, seawater pretreatment, arsenic removal, primary and secondary treatment of wastewater for reuse, and bacterial treatment of mineral water.

What are the differences between ultrafiltration (UF) systems and reverse osmosis systems?

Ultrafiltration systems can filter the finest solid particles in liquids, but they cannot filter out dissolved particles like reverse osmosis systems. However, ultrafiltration systems can filter smaller particles than microfiltration or standard activated carbon filters. Therefore, if you want to reduce total dissolved solids (TDS) content, you must use reverse osmosis water purification system. Ultrafiltration membranes can remove impurities as long as the particle size is greater than 0.01 micrometers.

What is the electricity consumption of the industrial UF system?

Therefore, this depends on the treatment capacity of the reverse osmosis water purification plant (in terms of liters per hour or per day). So, the power supply voltage range for our reverse osmosis water treatment system is 220 volts to 480 volts, with a frequency of 50 hertz or 60 hertz.
