Step Screen was invented by HUBER’s Swedish subsidiary Hydropress AB in the early 1980’s and has been the most copied fine screen.
Across Australia and New Zealand hundreds of step type screens have been installed with many now reaching the end of life.
So do you replace the step screen with a new one or with an alternative technology?
Since the invention of the step screen many different screen types are now available on the market which offer higher screening capture rates.
A summary of solutions from Hydroflux Epco is as follows:
|RakeMax Mutli Rake Bar Screen||
|Escamax Band Screen||
There are numerous items to consider when replacing a step type screen:
- Screening capture rates
- Additional headloss and hydraulic considerations that the inlet works can sustain
- Reliable washwater supply is required with some screen types
- Channel modifications to accommodate a new type of screen
Hydroflux Epco’s staff have been involved with sewage screening technology since the mid 1990’s and can provide advice on how to approach the replacement of your existing step type screen with either a new or alternative screen type.
