TI  - Dairy farm wastewater treatment by an advanced pond system.
PG  - 291-7
AB  - Waste stabilisation ponds (WSPs) have been used for the treatment of dairy farm 
      wastewater in New Zealand since the 1970s. The conventional two pond WSP systems 
      provide efficient removal of wastewater BOD5 and total suspended solids, but 
      effluent concentrations of other pollutants including nutrients and faecal 
      bacteria are now considered unsuitable for discharge to waterways. Advanced Pond 
      Systems (APS) provide a potential solution. A pilot dairy farm APS consisting of 
      an Anaerobic pond (the first pond of the conventional WSP system) followed by 
      three ponds: a High Rate Pond (HRP), an Algae Settling Pond (ASP) and a 
      Maturation Pond (which all replace the conventional WSP system facultative pond) 
      was evaluated over a two year period. Performance was compared to that of the 
      existing conventional dairy farm WSP system. APS system effluent quality was 
      considerably higher than that of the conventional WSP system with respective 
      median effluent concentrations of BOD5: 34 and 108 g m(-3), TSS: 64 and 220 g 
      m(-3), NH4-N: 8 and 29 g m(-3), DRP: 13 and 17 g m(-3), and E. coli: 146 and 
      16195 MPN/100 ml. APS systems show great promise for upgrading conventional dairy 
      farm WSPs in New Zealand.
