Highest Demands on the Fitting Technology
Protecting our environment requires sophisticated plant and process technology. Thus, the requirements of the planners and operators of systems for water technology to the reliability and reliability of the fittings are used. In addition, planners, plant constructors, as well as the operators in the selection of the valves oriented from an economic point of view increasingly oriented to ...

Water purification by functionalised self-assembled monolayers on silica particles
This study focuses on a novel method to remove bio molecules and pathogens of different nature, such as proteins, viruses and oocysts, from water by silica particles coated with functionalised self-assembled monolayers. The results clearly show that organic species can efficiently be removed at pH ranges of drinking water by stirring the coated particles in the contaminated water for up to 60 min ...

Method for trihalomethane analysis in drinking water by solid-phase microextraction with gas chromatography and mass spectrometry detection
Headspace solid-phase microextraction coupled with gas chromatography and mass spectrometry detection (HS/SPME-GC/MSD) was optimized for trihalomethane (THM) determination in drinking water. A 75 μm fiber coated with carboxen/polydimethylsiloxane (75-CAR.PDMS) was used. Experimental parameters such as sample volume, time and temperature of extraction, time and temperature of desorption, ...

Leaching of bisphenol A and F from new and old epoxy coatings: laboratory and field studies
Laboratory tests were carried out with three types of new epoxy resins to assess the release of bisphenol A and F (BPA and BPF) and potential halogenated phenolic by-products. Tests were carried out over a duration of 6 months in the presence and absence of disinfectants (chlorine and chlorine dioxide) at realistic doses and contact times. None of the three systems exhibited Fickian-type ...

Evaluation of model parameters for simulating TiO2 coated UV reactors
A CFD-based model for simulating TiO2 coated photocatalytic reactors used in drinking water treatment applications was preliminarily evaluated. The model includes aspects of hydrodynamics, mass transfer, UV-radiation field, and surface chemical reactions. Appropriate models for each of the associated physicochemical phenomena were experimentally or analytically examined. Once defined and ...

Manganese oxidation and bacterial diversity on different filter media coatings during the start-up of drinking water biofilters
Manganese removal is a typical concern in drinking water production. Biofiltration may be used when treating groundwater sources but the onset of manganese removal in virgin biofilters can vary considerably. The aim of this study was to investigate the effect of different filter media on manganese oxidation and bacterial diversity in biofilters during the start-up. The onset of manganese ...

First Stainless Steel High-Flow Filter Housing Hits the Market
Stainless Steel Housings the Key to Improved Filtration Performance As manufacturers look to increase the performance of their filtration systems and avoid the costs of replacing equipment, stainless steel housings are definitely a versatile problem solver. In the manufacturing world, filtration systems are truly put to the test. They must withstand high temperatures and pressure, are exposed ...

Concrete Water Tank Relining and Repair Case Study
These images show the concrete tank before any preparation work and then after preparation and concrete water tank relining and repair. The concrete tank was fully relined with Acothane DW. This underground, concrete, water storage tank is located at a university and sized at approximately 12m x 3m x 3m. The fibre glass lining that had been previously applied to the floor and part of the side ...
