As part of the Singapore MIT Alliance (SMA) we have established the Center for Polymer Microfabrication (CPM) with an initial focus on processes and systems related to volume production of microfluidic devices. This research has focused on topics as diverse as material processing property characterisation and simulation, tooling and equipment design and control, and process control and metrology. This paper details a unique project undertaken by this group to explore how all this related by disparate research can be combined to actually produce functional products in volume at acceptable production rates and quality levels. The goals of this work are not only to test the individual research findings of the group, but to explore and experience the needs that are added by such a production goal. For example we found that rate is an overwhelming constraint, and that tooling and fixturing are major requirements for successful production. Also, our metrology methods had to be adapted to meet our rate goals, which were set at a Takt time of less than four minutes.
Process analytics in polyethylene (PE) plants – Case Study
For the production of polyethylene a variety of processes is in use depending on what final products are intended to be produced. However, regardless of the process type, all plants require process analytical equipment to collect reliable and accurate information for process control, product quality, plant safety and environmental compliance.Siemens, a leader in process analytical instrumentation, has proven over decades its capability to plan, engineer, manufacture, implement and service analyzer systems for...
Leachate Collection & Removal Systems – Pump Stations
Romtec Utilities designs and supplies pump stations for many different types of applications, including leachate collection and removal systems. Leachate pump stations are required whenever water passes through a bed of solids and extracts contaminating elements. The most common scenario for collecting and pumping leachate is for landfills, but there are industrial applications as well. Leachate can be corrosive, acidic, and toxic toward all lifeforms and for many years was allowed to runoff into watersheds or...
BAIONI supply complete dewatering centrifuge system for APS Ltd
Situated near Slough, in Berkshire, Aggregate Processing Solutions (APS) is operating a washing plant where Baioni has recently supplied a centrifuge system to complement the whole existing plant. Baioni has boosted the capacity of its decanter centrifuges range to pave the way for further improvements in waste water and sludge treatment for a wide range of feed solids and flows. The Italian company has invested in a new application for centrifuge systems, that of a compact dewatering unit fully equipped mounted...
Common Ion Exchange System Problems and How to Fix Them
Ion exchange (IX) systems can be an efficient solution for various demineralization, purification, and wastewater treatment needs. In fact, IX systems deliver several advantages over chemical treatment, as they generally require less space, less labor, no sludge disposal, and lower operational costs. While such benefits are attractive, you might be left wondering “What are common problems with ion exchange and how do I fix them?” This article will offer insight into the key conditions and issues that...
What is an Ion Exchange System and How Does it Work?
Ion exchange (IX) systems are used across a variety of industries for water softening, purification, and separation purposes. While the chemistry of individual ion exchange reactions vary from one application to the next, IX is a treatment process where dissolved ions are replaced by other, more desirable, ions of a similar electrical charge. If you’re wondering whether IX is right for your facility, you might be asking “What is an ion exchange system and how does it work?” The following...
