Andritz separation launches low-profile belt press
Technology news Filtration+Separation November/December 2014
GE’s latest membrane technology GE has introduced its latest in membrane-based wastewater treatment technology, combining anaerobic digestion technology with its ZeeWeed 500 membranes to create anaerobic membrane bioreactor (AnMBR). As industrial customers seek greater water reuse, while facing more stringent discharge limits, AnMBR could offer lower costs, better performance and the ability to generate renewable energy from industrial wastewater. GE’s new technology is a solution for industrial wastewater with high biochemical oxygen demand and chemical oxygen demand concentrations that result in higher aerobic treatment operational expenses. GE
claims that its AnMBR provides reduced energy consumption, energy recovery and reduced sludge production both economically and reliably. By combining anaerobic digestion and ZeeWeed membrane technology, GE says that it has solved the issues associated with traditional anaerobic processes. GE’s AnMBR separates solids retention time from hydraulic retention time for a more robust biological process, retaining methanogens in anaerobic reactor, increasing methane production with no suspended solids in permeate and improving final effluent quality. http://www.ge.com/
Sterilising-grade air and gas filters from 3M New LifeASSURE PFC sterilising-grade air and gas filters from 3M feature an advanced ethylene chlorotrifluoroethylene (ECTFE) membrane, combining reliable micro-organism retention with high airflow performance, efficiency and durability. The single-layer ECTFE membrane is validated by liquid bacteria challenge, and has demonstrated complete aerosol retention of the bacteriophage. The hydrophobic nature of ECTFE ensures continuously high airflow and low pressure drop throughout a long service life by preventing blockage due to moisture. In addition, specially designed polypropylene flowenhancing layers help maximise efficiency. The membrane is contained in a Single Open-End (SOE) filter cartridge capable of withstanding multiple exposures to autoclave or steam cycles. The LifeAssure PFC series complies with food and beverage industry regulations, and is suited to sterile filtration or
Andritz separation launches low-profile belt press
New low-profile belt press from ANDRITZ Separation.
International technology Group Andritz is offering its customers a new belt press for dewatering in municipal and industrial applications, based on a new low-profile design and flexible modular construction. The main benefit of the new belt press is the size and weight; this has reduced by around 50% each compared to the previous machine generation. This means
easier access to the machine, lower investment costs for the customer but achieving the same machine performance. With an overall height of only 150 cm (approximately 60”), the gravity zone is at the ideal working height, resulting in reduced time and costs for operating and maintenance work, as well as increasing the availability of the machine. www.andritz.com
Xylem in water treatment plant upgrade
LifeASSURE PFC sterilising-grade air and
Xylem, has provided ultrafiltration solutions as part of the upgrade of the Santa Eufemia municipal water treatment plant, north of Oporto in Portugal. As a result of the upgrade the plant has a new capacity of 24 million litres per day, providing clean drinking water to 80,000 people in the Guimarães and Vizela regions.

use in small and economical vent filter assemblies. Typical filtration applications include filtering process air as well as use in largescale fermentation air inlet and exhaust systems, or blow, fill and seal machines. Venting applications include venting tanks, lyophilizers and autoclaves. www.3M.co.uk/filtration
Xylem has worked with Moinhos Ambiente, the company in charge of engineering, procurement and construction for the project to provide GE’s ZeeWeed 1500 membrane modules and Lowara pumps, as well as process and design engineering support, in a contract worth €430,000 to Xylem. Plant upgrade work was required as a result of deteriorating
water quality from the nearby Rio Ave river. The Santa Eufemia drinking water plant is now one of the largest installations of GE’s ZeeWeed 1500 modules in Europe and the Middle East. GE’s ZeeWeed 1500 membranes were chosen for the Santa Eufemia plant because of their reliable filtration that provides superior water quality. The ultrafiltration system provided by Xylem is designed with four parallel membrane trains each incorporating 88 membrane modules. This ensures full system capacity and as it is fully automated, minimises operator intervention. www.xylem.com
