Metal matrix composite solves thermal management issues
The metal matrix composite AlSiC (aluminum silicon carbide) provides cost-effective solutions for the thermal management of heavy equipment electronics used in water treatment and waste management facilities, according to CPS Corporation.
 |
The material makes AlSiC components lightweight, high strength and tolerant of in-service shock and vibrations that occur in these type of facilities. Unlike traditional packaging materials, AlSiC enables a tailored coefficient of thermal expansion (CTE), offering compatibility with various electronic devices and assemblies. The isotropic CTE value of AlSiC can be adjusted for specific applications by modifying the Al-metal/SiC-particulate ratio. AlSiC’s CTE matching capabilities eliminate the need for thermal interface stacking.
AlSiC exhibits high thermal conductivity that results in efficient thermal dissipation. Coupled with its CTE matching, AlSiC’s high thermal conductivity prevents the bowing and flexing of packaging and substrate material that can lead to failure. Traditional packaging materials with lower thermal dissipation can cause delamination, leading to air gaps and poor reliability.
The CPS AlSiC near and net-shape fabrication process produces the composite material and fabricates the product geometry, allowing rapid prototyping for high volume advanced thermal management solutions. The casting process enables integration of very high thermal conductivity inserts (>1000 W/mK) or cooling tubes for more advanced thermal management solutions.

Brawoliner® system renovates Jersey sewers
Since 2004, Bell Services Ltd. installed some 2,000 meters of pipeline using the German-manufactured Brawoliner® system from Karl Otto Braun KG (KOB) on Channel Island, Jersey, UK. The system was used to reline deteriorated pitch fiber and vitrified clayware sewer and surface water pipes across the island.
Bell Services is the Dyno Rod franchise holder for Channel Island. The company worked closely with CJ Kelly Associated Ltd, an independent specialist sewer renovation consultant and KOB’s technical representative in the UK and Ireland.

Some examples of projects undertaken on Channel Island include the renovation of a 100- mm-diameter pitch fiber pipe, adopted by the Public Services Department, running from a road, across a private property and under a pond that was re-rounded and lined. The pipeline served a number of blocks of flats managed by Rumsey Management, totalling around 50 residences, on a private estate. The sewer system serving the community was originally 6-in-diameter pitch fiber pipe, running at depths between one and three meters, which, on CCTV inspection, showed some deterioration. The original pipeline did need repair or replacement, so Rumsey brought in Bell Services to complete the work.
The project comprised the open cut replacement of some of the pipeline, but large sections of it was rehabilitated using lining techniques. In all, five lengths were lined by employing KOB’s Brawoliner system using manhole-to-manhole lining techniques. The lining runs included two lengths of 100-mm diameter that ran beneath buildings, one length of 100-mm diameter that ran under a garage, one 86-m-long section of 150-mm diameter that lay beneath a road and, ultimately, two 45-m lengths further 150-mm diameter. All of the installation sites were in sandy ground.

The Brawoliner system uses a seamless lining textile fabric that is applicable to pipes from 75- to 255-mm diameter, with wrinkle-free installation around 90o bends. The system is generally compressed air inverted from an inversion drum and can be used as an ambient or hot water cured installation.
The majority of the installations were completed with relative ease, although prevailing conditions on the 86-m-long run meant created difficulties. Bell Services reduced the length of the final linings by installing a new manhole half way along the proposed length, which allowed the final lengths to be made in two 45-m runs instead of another 90-m shot. The project was successfully completed as scheduled.

Water companies study meter exchange programs
Accurate metering is widely accepted as a key factor in water supply efficiency among utilities, but how do water companies know whether meters installed in the distribution network many years ago are still the most effective for their specified purposes?
Sensus Metering Systems has developed software that measures meter efficiency and is currently piloting this approach with several water companies. A recent project undertaken by Sensus using its Optimal Sizing Maintenance Software (OSMS) demonstrated that a meter exchange program would provide a 20 percent average increase in recorded revenue, delivering a payback to the utility over just a two-year period with significant operational benefits.
The ultimate purpose of OSMS is to assist in measuring the cost-effectiveness of each meter in a supply network. In this way, utilities begin to improve performance in the supply process through a program of meter review and, if necessary, replacement. Greater meter accuracy helps water companies reduce unmeasured supply. The program evaluates the performance of meters through a minimum seven-day data profile. The assessment involves analyzing the log against defined parameters, including accuracy of measurement in a variety of flow conditions, and then projecting any pay-back potential accruing from a meter exchange program.
The measurement criteria typically applied to meters Dn50 and above focus on total consumption, meter age (meters of 15 years or older may suffer from inaccuracy), change in the customer profile (eg lower or greater consumption), meter type and size and customer processes (perhaps as a result of change in ownership).
For installations where there is no logged data, it is still possible to generate an accurate statistical meter profile by focusing on a range of accepted usage criteria and supply conditions. All event profiles used in the software have been taken from internationally recognized standards.

Filtration system certified as microbiological water purifier
Through independent testing, Zenon’s whole home Homespring UF200 series ultrafiltration systems are now certified to meet the US Environmental Protection Agency’s (USEPA) “Guide Standard and Protocol for Testing Microbiological Water Purifiers.” It is the first series of whole home water filtration systems to be certified as a Microbiological Water Purifier.
The Homespring Central Water Purifier can be used on treated municipal water and untreated well or lake water. On municipal water sources, the system can provide chlorine-free, bottled water taste to every faucet in the home even in the event of a boil water alert or if pathogens are picked up along the distribution lines.
 |
The two-stage whole home water filtration system uses granulated activated carbon (GAC) to pre-filter the water and remove unwanted taste and odors, such as chlorine. The second stage uses thousands of strands of Zenon’s ZeeWeed® hollow fiber membranes, which filter down to 0.02 microns (nominal) and physically remove turbidity, bacteria, viruses and cysts from the water. Using only the inlet water pressure, the systems can filter up to 11 gallons of water per minute without electricity and have a built in daily self-cleaning cycle.
The USEPA Guide Standard and Protocol for Testing Microbiological Water Purifiers tests the ability of a microbiological water purifier to remove pathogens, such as bacteria, viruses and cysts from contaminated wells and surface water sources during normal and emergency situations (boil water alerts and natural disasters).
BioVir Laboratories independently tested the Homespring UF200 system and detected no microbiological organisms after being filtered by the Zenon membranes. According to Tom Palkon, director of product certification for the WQA, “The systems have gone through rigorous testing to meet the Water Quality Association’s ANSI accredited Gold Seal Certification program. The Homespring systems are the first Point Of Entry Filtration systems we have certified as a Microbiological Water Purifier.”
The Zenon systems have been used in developing countries to provide potable water for homes, apartments, villages and schools. They were also deployed for use in the Asian Tsunami and Hurricane Katrina disasters for aid relief where they were used to supply potable water to thousands of residents and relief workers.
