A pretreatment system using media derived from the recycled husks of coconuts (100% coir fiber) was evaluated using 20 permanently occupied single-family residences located in the State of Virginia. Sampling began in the summer of 2009 and continued to the summer of 2011. Home locations ranged from the mountainous regions of western Virginia to sandy low relief sites on the Eastern Shore of Virginia. Concentrations of biochemical oxygen demand, total suspended solids, and nitrogen species (TKN, nitrate + nitrite) were measured in system influent and effluent four times (once in each season) for each home. Total phosphorus was measured from each home’s influent and effluent once during the study. This paper provides information on the performance of this attached growth treatment system under real world conditions.
This year the National Environmental Health Association (NEHA) has added a new way to participate in the Call for Abstracts process for the Annual Educational Conference (AEC) & Exhibition. It is called, "Be a voice" and it gives you the opportunity to tell us what you’d like to experience at the AEC. Tell us topics you’d like to hear about and speakers you’d like to see. Review abstracts and provide input.
Help NEHA develop a training and education experience that continues to advance the proficiency of the environmental health profession AND helps create bottom line improvements for your organization!To search for specific abstracts, please use the search box located at the top left of the page (*next to the Blogger icon).
