Has our municipal wastewater changed during the past decade? Perhaps it’s not too bold to say there is a broad consent throughout the entire industry that it has changed dramatically. For instance, new extremely durable tissue materials have challenged even the most powerful pumps and exasperate water companies, as well as pump manufacturers.
Three main approaches can be observed among the leading pump manufacturers trying to handle these complications:
a) New hydraulic impeller designs
b) Intelligent control algorithms
c) Solid separation systems
Whereas approaches a) and b) should help the pump to cope with the ‘new’ wastewater, c) aims to avoid any contact between solids and rags and the pump and subsequently prevent it from clogging.
A (moving) picture is worth a thousand words. This is what I am talking about (courtesy of KSB):
More and more manufacturers (among those are well known brands like Hydro-Vacuum S.A. Grudziądz, KSB Company, Strate or WILO SE) offer high quality solid separation systems and the technology has graduated to an advanced level.
Here in Eastern and Central Europe it seems the triumphant sweep of the solid separation system is unstoppable. Today they are not only found at several booths here at the Vod-Ka exhibition in Prague but also underneath a growing number of public buildings (Industry insiders know too well that large public buildings as airports, railway stations or hospitals have their very special wastewater challenges.) and in the extensive pressurized sewers from Berlin to Bucharest and from Warsaw to Zagreb.
Will this technology find its way to North America? You are invited to comment this post if you want to discuss or share your personal solid separation experience.
