The new mobile NivuFlow Mobile 600 flow transmitter has been developed particularly for long-term measurements in full pipelines. Very high endurance is achieved thanks to energy-efficient algorithms, performance-optimised sensors and high-capacity rechargeable batteries. Utilising a five-minute-cycle for measuring and recording, it is possible to measure up to one year without battery replacement. Featuring 182.000 storage cycles, the internal data memory is conceived for even longer measurement periods. Contactless clamp-on sensors and pipe sensors for direct measurement in the medium are available. Both sensor types share quick and easy mounting without the need to shut down running processes. The clamp-on sensors do not have any medium contact and are clamped onto the pipe outside. Thanks to the high protection rating of sensors and transmitter (IP68) it is possible to operate the measurement system even under harsh ambient conditions. For example, batteries can be replaced by the operator even during heavy rain. This ensures uninterrupted measurements even for long-term projects. The transmitter is controlled on site by using smart terminal devices such as smartphones, tablets or notebooks. Connection is set up using a WLAN created by the transmitter itself. No plug-ins or apps need to be installed to operate the system. During poor weather conditions, in strong sunlight or in case of limited access to the measurement site it is hence possible to operate the instrument from protected areas such as service vehicles etc. Typical NivuFlow Mobile 600 applications are: leakage detection, heat quantity measurement, pump verification, water supply monitoring, monitoring of inlets and outlets conducting cooling water or circulation systems as well as monitoring of process water and service water. www.nivus.com
LANXESS adds CCRO module to design software
LANXESS Sybron Chemicals, a subsidiary of specialty chemicals company LANXESS, has announced a significant addition to its LewaPlus® software suite of reverse osmosis (RO) and ion exchange (IX) system dimensioning capabilities. The new module provides system modeling with Desalitech’s Closed Circuit Reverse Osmosis (CCRO) technology and enables the dimensioning of RO systems using the latest available water treatment technology, helping system designers bring their water treatment footprint closer to zero liquid discharge (ZLD) or minimum liquid discharge (MLD) goals. The system operates in two alternating modes: Closed Circuit (CC) mode at 100 percent recovery and Plug Flow (PF), or flushing mode, at 10 percent to 50 percent recovery. During CC operation, permeate is produced at a rate equal to the flow rate from the high-pressure pump. When a desired recovery percentage is reached, the operating mode is switched to PF mode in which concentrated brine is purged from the system and displaced by feed water from the high-pressure pump in a single plug-flow sweep. The new software module was developed cooperatively by LANXESS Sybron Chemicals and Desalitech, Inc. (Newton, MA, USA). Until now, the modeling of the CCRO process was based on experience values without energetic optimization, which generally limited CCRO projections for recovery rates and system capabilities. https://lanxess.com
Geopolymer passes corrosion resistance test
Quadex’s GeoKrete Geopolymer meets the most demanding European test standard for corrosion resistance, WXX4, as defined by DIN 19573: Mortar for Construction and Rehabilitation of Drains and Sewers Outside Buildings. This test was created by the Hamburg Society for urban drainage to ensure mineral based repair and renovation products meet a minimum standard of resistance for biogenic acid corrosion. In order to comply with DIN 19573, in all testing phases, GeoKrete possessed a relative residual compressive strength greater than 55 percent for pH0, and greater than 75 percent for pH1. GeoKrete is used for the repair and rehabilitation of manholes, large diameter pipes and other sewer infrastructure requiring exceptional structural and corrosion protection. www.quadexonline.com
