Engineering is a very broad term used to describe manufacturers and producers of raw components, often used in larger assemblies. The assembled equipment can use filtration components to suit the application’s water requirements although here we focus on the production processes used to manufacture finished engineering components. Processes such as grinding, milling and drilling benefit from using depth filtration to remove swarf that if reintroduced, could damage the component. The coolant used in these processes is often expensive and by removing particles collected, makes the coolant lifecycle, longer.
The same techniques are applied using surface cartridges to polish water and other liquids before they are applied to the component. Incoming water to these sites is often softened using a softening system to prevent scale build-up within the expensive equipment, keeping the machines running efficiently. Where boiler feed is a requirement, the softened water is used in conjunction with a reverse osmosis (RO) system to produce water of such high quality that boiler ‘blowdowns’ are significantly reduced, saving energy costs.
Incoming Water and Boiler Feed
Water fed to site should be softened to protect the expensive machines from scaling that can affect energy use, accuracy and visibility on gauges/screens.
Softened water in combination with a reverse osmosis (RO) system is also used to feed the boiler, reducing the amount of ‘blow downs’ to save energy costs.
Coolant Swarf Removal
For processes such as milling, grinding, cutting and drilling applied to precision engineered components, the quality of the lubricating coolant is important.
Keeping the coolant free from particles prevents damage to the piece being worked on, keeping yields high. Typically, coolant is recirculated through a depth filter cartridge to remove particles.
High performance, precision engineered components often have the requirement to be thoroughly cleaned before a process or before packing.
Deionised water is preferred generally as it ensures a spot free finish on the component.
