What is Ultrafiltration for Tertiary Wastewater Treatment?
UF is a membrane filtration method which pushes water, across asemi-permeable membrane, using a hydrostatic pressure. The ultrafiltration membrane typically has pores between 103 and 106 Daltons in size. For water creation with extreme high purity and low silt density, ultrafiltration uses pressure as a pressure-driven barrier to suspended particles, bacteria, endotoxins, as well as other pathogens.
Let’s understand how ultrafiltration acts as a tertiary wastewater treatment.
Process of ultrafiltration
In ultrafiltration (UF), a liquid is forced against a semi-permeable membrane by hydrostatic pressure. Water and solutes with low molecular weight pass through the barrier, whereas suspended solids and solutes with a large molecular weight are trapped. Except for differences in molecule size, ultrafiltration is basically similar to reverse osmosis, microfiltration, and nanofiltration.
Pore size of ultrafiltration membranes
Almost, all colloidal particles (0.01 to 1.0 microns) and some of the biggest dissolved pollutants, are removed from water with ultrafiltration (UF). The kind and size of pollutants removed are mostly determined by the pore size, in a UF membrane.
Membrane ho?les typically have a size between 0.005 and 0.1 microns
Each UF product is categorized by the producers of UF membranes, as having a particular molecular weight cut off, which is a rough estimation of the size of pollutants eliminated by a specific UF membrane.
A 100,000 MWC UF membrane ensures that almost none of a given standard substance, which has a molecular weight of about 100,000 Daltons, will pass through the membrane when water containing it is introduced to the UF unit.
The size of materials having a molecular weight of 100,000 Daltons ranges from 0.05 microns to 0.08 microns. Most pathogenic organisms and nearly all colloidal particles must be eliminated, when utilising UF membranes, however most dissolved solids can pass through the membrane without producing issues further down the line, or in the final product water. Most turbidity in water will be eliminated by UF.
Why is membrane filtration required?
Our need for fresh water is growing yearly, and the market for water re-use technologies, has been gradually expanding. Netsol Water has created a standard product line of packaged Ultrafiltration (UF) membrane systems and Reverse Osmosis Plants, in response to this demand.
The systems are added to already-existing domestic wastewater treatment facilities. UF offers tertiary treatment, producing high-quality water for reuse purposes, like irrigation or cooling water. The high-quality water can also be utilized to supply reverse osmosis systems, with the process water they need.
UF is a pressure-driven membrane separation technique that clears water of suspended particles. Additionally, it eliminates some dissolved materials with high molecular weight, such as colloids and organics. The majority of viruses and bacteria found in water are effectively removed by UF membranes.
The technology is perfect for tertiary wastewater treatment because UF systems can eliminate bacteria, and the majority of viruses. Pathogens are completely blocked off from the public by the membrane. Additionally, since there are almost no suspended particulates in the filtered water, the amount of chlorine, UV, or ozone that must be dosed, is considerably decreased.
