UNIQUE STANDARD FEATURES INCLUDE
SIRM – Shakesby Iron Removal Media. Our own propriety catalytic filter media is a light weight material which accelerates the reaction between oxygen and iron. As a catalyst, it is not used up in this action and is classed as a permanent media. Under normal operating conditions SIRM should achieve many, many years of service and is not routinely replaced keeping lifetime running costs to a minimum.
True, air scour back wash. This has been a key feature of Shakesby filters since the early days of development. The fact that the air scour back wash flow rate is typically half that of the service flow rate ensures reduced water usage without compromising efficiency. Pumps can be specified for service rather than back wash flow rates.
Back wash flow rate is half that of the service flow rate. Using our unique design and components it is possible to achieve this key benefit for you. It is especially relevant when comparing other filters on the market. These, at best, have the same back wash and service flow rate with some requiring higher than the service flows.
Aeration, venting and filtration all in one unit. The combination of unique components within our filters can induce air into the incoming water, vent off excess air and unwanted odours, such as Hydrogen Sulphide (the rotten egg smell), and retain the iron deposits all within one vessel, saving on space and additional components.
Unique ‘spider’ distributor (except EB). Developed to overcome a number of issues the spider has been used in our filters since the early days. Its design allows:
- Easy installation into the 6” flanged filter vessels
- Even and efficient water flow in both back wash and service
- It removes the need for a gravel support bed
Air draw protected by a nominal 0.2 micron air filter. Aerating iron removal filters have to draw air into the water. However, this is a potential contamination point. If, for instance, a filter is installed in a dusty or dirty environment then particulate could easily been drawn into the water stream. All Shakesby filters are protected by nominal 0.2 micron air filter which can stop bacteria as well as particulate.
The SM filter uses two air inlets one for service and one for backwash.
