Scarab Water - Balancing act for sewage treatment plants

Scarab Balancing act

Scarab Balancing down under

When asked to install a small sewage treatment system for a 2 bed-roomed house, in Brisbane Australia, we knew we would need to be really innovative. Something we had not tried before.

House was on concrete piles, and the floor level was about 1m above the ground. The objective was to get wastewater through the plant, all gravity, and through to disinfection.  From there treated water would discharge onto the lawn.

Balancing - the process of leveling high peak flows (morning and evening)  and low flows (when everyone is at work, or sleeping). This is important to maintain the correct biological process.   Normally we would have a small submersible pump , gently feeding the bio-reactor. 

But  . . .  could balancing be accomplished without this pump? And would the new design avoid any negative effects of peak loads?

Yes -  Scarab did it!

And -  the plant actually increases it's capacity during peaks, which gives the bacteria more time (retention period) to biologically process the water, during the early morning rush. We suggested that the Scarab system's appetite got bigger during the busy periods.

In layman's terms, imagine the freeway getting wider during the morning traffic.    

- Treating your water to a well balanced, unique Scarab system.
