One tank, a smart cycle that’s why it’s cost-effective
Both of our development systems use SBR (Sequencing Batch Reactor) — the most cost-effective technology for a strong result on medium loads. Instead of needing a separate settling tank, an SBR does everything in ONE tank, in a timed cycle.
01
Fill
Wastewater enters the reactor.
02
Aerate
Air is injected; bacteria break down the pollution.
03
Settle
Aeration stops; treated water clears as solids settle.
04
Sludge
Excess sludge is returning to primary tank via airlift .
05
Decant
Clean treated water is drawn off the top.
06
Treated water extraction
Treated water is extracted via airlift in the collector .
Roto
For new projects we use Roto rotomolded , watertight polyethylene (PE) tanks running an SBR cycle. PE is durable, leak-proof and quick to install, making it ideal for new residential and commercial developments.
Guamikeni is the exclusive reseller and installer of Roto.
