Kunshan, China

The ALGAESYS plant in Kunshan was an 8 month Research and Development project undertaken by our CEO John Fagan in 2015. The purpose of this plant was to perfect the treatment train efficacy by physically testing all parameters including log size and makeup, log rotation speeds and all physical and process aspects of plant design. This was an iterative experimentation using multiple ALGAESYS treatment chains to compare results and lock-in improvements to process efficiency. The influent was delivered from four local municipal wastewater sources, so the system was treating up to 80kL of wastewater each day.

The following process performance results were measured in the Kushan prototype (between April and November 2015) with an average wastewater treatment time of 6 hours (range 4 hours to 8 hours): The efficacy of this process, in terms of disinfection of harmful pathogens (typically measured as E.coli in CFU/100 ml), is several orders of magnitude higher than conventional wastewater treatment systems, which are in the region of 4 log10 CFU/100 ml if no additional disinfection step is taken. This demonstrated that ALGAESYS effluent could be reused without further treatment in agriculture under EU Class C.
