Water Flow

What Green Star Does


Green Star's "GSI Clean" treatment process is proven to eliminate consistently 93% of TSS on the first pass.

Laboratory test results by GSI have exceeded current Anaerobic digestion.

The "GSI Clean" Process

Green Star has a process called "GSI Clean" that reduces the organic load in primary wastewater. It is a continuous flow with a throughput of influent and a residence time of 15-24 hours in the reactor.

Compared to present aerobic process, requiring high oxygenation in the reactor for efficiency, the "GSI Clean" process reduces oxygenation and maintenance costs.


The GSI Clean treatment process is the solution to saving money, creating green energy solutions and improving WWTP to become energy neutral.
