Membrane filters are purification filters that remove solid particles from water. Membrane is widely used in water treatment plants using filtration method. Membrane filter has a key role for water purification systems. Membrane technology has been accepted as a common purification technology from past to present. Membrane technology draws attention with its many advantages.
What is Membrane Filter?
The membrane is a sheet of synthetic plastic material that can be said to have very fine holes or pores. However, considering the different types of water treatment membranes, there may be differences in the size of the pores.
Membranes basically have a simple system. It appears as systems that act as a special filter by filtering solids or other substances and allowing water to flow. Membrane filters are preferred for many purification processes such as sediment purification techniques, distillation.
Membrane filters are very important for all domestic or industrial water purification devices due to their high purification power. Membrane filters are surrounded by non-permeable or semi-permeable membrane-shaped plastic material.
When the water to be purified comes to the membrane filter, it is purified from all harmful particles and invisible chemicals through this membrane. While the wastewater generated as a result of treatment is discharged from one of the membrane filters with two different outlets, the treated water passes through the other filters inside the device from the other outlet.
What are the Membrane Types?
Membranes come in many varieties. Membranes are generally available in flat plate, hollow fiber, tubular, and multihole options.
Flat Plate Membranes
Flat-plate membranes are sheet-shaped. While there is an active separating layer on one surface, the water purified from the membrane is obtained on the other surface.
Hollow Fiber Membranes
Hollow fiber membranes are cylindrical in shape. This type of membrane, which can work in two ways, can work from the inside out and from the outside in.
Tubular Membranes
Tubular membranes with a cylindrical shape and large diameters are especially used in waters with high suspended solids. These membranes work with the principle of inside-out.
Multihole Membranes
This type of membrane, which has many water flow channels in its structure, is called multi-hole. Working on the inside-out principle, these membranes can be polymeric or ceramic.
