Until recently, using membranes for whole-house residential clarification and disinfection had not been an option for water treatment dealers. Technical advances made by Zenon Environmental in hollow fiber membrane technology for its large-scale municipal and industrial plants have changed this. Membranes are now being used in the company’s Homespring point-of-entry (POE) systems, providing a cost- effective solution for the removal of turbidity and pathogens, and delivering clear, biologically safe water.
Field applications of Homespring ultrafiltration units
A study published as part of the EPA's Environmental Technology Verification (ETV) Program verifies the performance of a Fyne Process membrane filtration plant tested on high organic-laden surface water in Barrow, Ark. The plant was able to remove significant levels of organics--precursors to disinfection byproducts such as trihalomethanes (THM) and haloacetic acids (HAA)--producing water that easily met the disinfection byproduct standards set by the EPA's stringent Stage 1 D/DBP Rule.
Membrane technology offers the possibility of managing total water resources. The spiral wound membrane element configuration is the most widely used due to its high packing density and relatively low price. This article will describe some technological advances in the area of innovative new membranes and application concepts for spiral wound membrane elements.
Ultrafiltration (UF) rapidly is becoming a common and practical method of preparing pure water that is free of particulate matter.
The Use of Nephelometric Light Scatter to Monitor Ultrafiltration Performance
The membrane processing technologies of microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) are widely used to separate suspended and dissolved materials from water solutions in numerous industrial, medical and drinking water applications.
The removal of impurities and contamination from water supplies or industrial chemicals is a process existing all over the world to varying degrees of sophistication. Filtration systems vary enormously according to location, the type of purification required and funding available.
An overview of various filtration methods and their applications
Municipal and industrial sectors are looking to new and innovative technologies to meet the demands of modern day consumers' requirements. One such technology is ultrafiltration.
