Best Practice Guide on Metals Removal From Drinking Water By Treatment

The EU Drinking Water Directive sets a range of standards for metals and related substances in drinking water, many of which are concerned with health protection. A number of these standards are very stringent and require compliance to be assessed at the point of use. Because of the difficulties associated with monitoring, historic practices in many countries have concentrated on the quality of water within the distribution network. As a resul

Handbook on Particle Separation Processes

Particles in water play an important role in all kinds of water quality and treatment issues. Since the early beginnings of centralised water production and treatment, the main goal of water purification was primarily the removal of water turbidity in order to produce clear water free from visible particles.The Handbook on Particle Separation Processes provides knowledge and expertise from a selected group of international experts wit

Biofouling of Spiral Wound Membrane Systems

High quality drinking water can be produced with membrane filtration processes like reverse osmosis (RO) and nanofiltration (NF). As the global demand for fresh clean water is increasing, these membrane technologies are increasingly important. One of the most serious problems in RO/NF applications is biofouling – excessive growth of biomass – affecting the performance of the RO/NF systems. This can be due to the increase in pressur

Operating Large Scale Membrane Bioreactors for Municipal Wastewater Treatment

During the last decade membrane bioreactor (MBR) technology has grown up to be state of the art in municipal wastewater treatment. Since 1999 the Erftverband has designed, tendered and commissioned three MBR for municipal wastewater treatment in Germany, with capacities from 3,000 to 45,000 m³/d. The Erftverband was one of the pioneers in the full scale application of the technology regularly hosted training and information workshops for

Performance Modification via Membrane Stretching

The objective of this research was to study the effects of uniaxial stretching on the structure of microporous membranes (especially the aspect ratio of the pores) and on the performance of these membranes as measured in terms of flux and particle rejection. The hypothesis of this research was that by stretching microporous membranes, their performance could be improved. Stretching a membrane was expected to elongate pores and change their asp

Water Treatment and Pathogen Control

Increasingly, microbial issues are commanding the attention of water treatment operators, regulators, and the media. There are many treatment options to eliminate pathogenic microbes from drinking-water. Finding the right solution for a particular supply requires sifting through a range of sometimes competing processes.

Quantitative Methods to Assess Capacity of Water Treatment to Eliminate Micro-Organisms

Ever since the recognition of the important role of water in the transmission of pathogenic micro-organisms in the 19th century, microbiological safety of drinking water has been a major research issue for microbiologists in the drinking water industry.
