Evaluation of electropositive filtration for recovering norovirus in water
The virus adsorption-elution (VIRADEL) technique has been widely used in the recovery of various enteric viruses in water, and an electropositive filter such as 1 MDS has been commonly applied. However, effective methods of monitoring waterborne norovirus (NoV) have not yet been well characterized and optimized. Hence, in this study, the VIRADEL technique was evaluated and optimized for ...

Evaluation of the flocculation and de-flocculation performance and mechanism of polymer flocculants
Understanding the interaction mechanism between polymeric flocculants and solid particles in two oppositely charged solutions: bentonite and calcium fluoride, is of great practical and fundamental importance. In this work, inorganic flocculants based on aluminum(III) or iron(III); cationic, anionic and non-ionic organic flocculants were used. The solution pH, which highly influenced the ...

Comparison of hollow-fiber ultrafiltration to the usepa viradel technique and usepa method 1623
Received for publication April 2, 2008. Hollow-fiber ultrafiltration (UF) is a technique that is increasingly viewed as an effective alternative for simultaneously recovering diverse microbes (e.g., viruses, bacteria, parasites) from large volumes of drinking water. The USEPA has organism-specific methods, including Method 1623 for Cryptosporidium and Giardia and the virus adsorption–elution ...

What is Sustainable Flocculation and What are Sustainable Flocculants?
What is Sustainable Flocculation? In most standard drinking water and wastewater treatment systems, there is a flocculation process that is used to reduce the concentrations of solids within the effluent stream. This particular process makes use of substances that aid in the clumping together of suspended particles among other contaminants in a clarifier system. Sustainable flocculation ...

Bio-Organic Flocculant Treatment for Phosphorus Removal: A Zeoturb - Case Study
Problems with Phosphorus in Wastewater Regulating the discharge of phosphorus from industrial and municipal wastewater treatment plants is a primary factor in averting eutrophication of surface water sources. Phosphorus is one of the key nutrients that contribute to this process in both lakes and natural waters. Its existence has caused major water quality issues such as diminished recreational ...

Occurrence of norovirus and other enteric viruses in untreated groundwaters of Korea
A total of 39 water samples from 23 different groundwater wells in Korea were collected and analyzed in order to monitor the occurrence of norovirus (NoV) and other indicator microbes as the first part of a national survey of groundwater. More than 500 L of untreated groundwater were filtered through 1MDS filters. Following elution and concentration by organic flocculation, PCR and sequence ...

What is Zeoturb Bio-Organic Liquid Flocculant Treatment?
In most standard water treatment systems, there is a flocculation process that is used to reduce the concentrations of solids within the effluent stream. This particular process makes use of substances that aid in the clumping together of suspended particles. There are several different substances that have been used for decades, but research continues looking for more. Ideally, newer flocculants ...

Coagulation, flocculation and agglomeration
Agglomeration Agglomeration refers to the formation of more or less firmly bound primary particles by collision processes between primary particles, primary particles and agglomerates, as well as pre-existing agglomerates. The agglomeration consists of a destabilization and a transport process. The destabilization is divided into coagulation and flocculation. In general, both mechanisms occur ...

The safe use of cationic flocculants with reverse osmosis membranes
Abstract Flocculants are used in combination with coagulants to agglomerate suspended particles for removal by filtration. This technique is used extensively in all types of surface waters to reduce the silt density index (SDI) and minimise membrane fouling. Although organic cationic flocculants are particularly effective, their widespread use in membrane applications is limited because of ...

Sustainable Thermal Power Plant Water Management: Overcoming Water Stress Challenges
The World Resource Institute (WRI) recently found that 47% of the world’s thermal power plant capacity is located in water-stressed regions. That’s highly problematic because thermal energy significantly depends on water for cooling and electricity. This requires efficient thermal power plant water management. If you manage a thermal power plant or consult those who do, you must ...
