Analysis of temporal trends in southern Nevada wastewater pond parameters with an emphasis on ammonia removal

This paper examines physico-chemical and biological properties and processes in four Southern Nevada wastewater pond systems located in Alamo, Beatty, Blue Diamond, and Searchlight. Pond parameters examined include pond dimensions, hydraulic retention time (HRT), alkalinity, pH, chemical oxygen demand (COD), biochemical oxygen demand (BOD), dissolved oxygen (DO), phosphorus, nitrates, and ammonia. Data on each pond and pond system are presented including pond system comparisons; A major focus of this paper is on ammonia-N removal. Individual pond ammonia-N removal performance is compared to published models. A model based solely on HRT in a given temperature regime is developed. Models describing Ammonia-N removal performance as a function of HRT, temperature, and pH are also developed. Ammonia-N removal mass transfer coefficients for well-mixed, plug flow, and plug flow with dispersion are also calculated.
