Book excerpt: Nitrate released from septic system effluents can percolate through the soil, potentially contaminating ground water and exacerbating surface water eutrophication. Alternatives to conventional septic-drainfield systems can remove nitrogen from this waste-stream, thereby protecting water quality. This study compares the nitrogen removal efficiency of two onsite treatment systems designed to maximize nitrogen removal via sequential nitrification-denitrification. The key requirements for denitrification (including oxic conditions for nitrification and anoxic conditions for denitrification and bioavailable carbon), were provided in both systems, however several key design features differed. The first system was a vegetated recirculating gravel filter (Vegetated RGF) and was designed as a single step system, incorporating nitrification and denitrification conditions in tandem and utilizing the septic tank effluent as the carbon source. The second system separated the nitrification and denitrification steps, using an RGF for nitrification and a vegetated woodchip bed for denitrification. Both systems were fed residential wastewater influent for one year. The two-stage Woodchip bed system provided far greater nitrogen and fecal coliform removal than the single-stage system, however, the two stage system was highly sensitive to temperature and removed less nitrogen during cold months. The Vegetated RGF average effluent total nitrogen (TN) was 15.1 ℗ł 1.9 mg/L, which equates to an average of 69% TN removal. The Woodchip bed system produced an average effluent of 1.7 ℗ł 1.0 and 6.4 ℗ł 4.2 mg-TN/L, during warm and cold months, respectively, resulting in an average TN removal of 92%. BOD, TSS and TP removal were similar in both systems. The Woodchip bed system exhibited exemplary nitrogen and fecal coliform removal and therefore has the potential to vastly improve residential wastewater treatment.

Book Synopsis Comparison of Traditional Standard Drainfield with Innovative B & G Treatment Bed for Nutrient Removal from Septic Tank Wastewater by : Fahim Hossain
Download or read book Comparison of Traditional Standard Drainfield with Innovative B & G Treatment Bed for Nutrient Removal from Septic Tank Wastewater written by Fahim Hossain and published by . This book was released on 2010 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays people are more alert about conservation of water and water scarcity. The amount of usable water is decreasing due to unavailability of pure water for day to day use. Both surface and groundwater is contaminated by untreated wastewater discharged from improper onsite wastewater treatment system, nutrient laden agricultural runoff and increasing use of fertilizer in fields. This elevated nutrient level is increasing the maintenance and operation cost of water treatment plant. So it is an important task to remove those nutrients from wastewater and other water bodies by applying environmental friendly process. In the USA, about 25% homes are still depending on on-site wastewater treatment (OSWT) due to unavailability of centralized treatment process. In Florida, OSWT is managed by the Florida Department of Health (FDOH). By realizing the importance of water conservation, USEPA already determined the maximum contaminant level (MCL) for nitrate and nitrite in water bodies. Many researches are conducted to evaluate the performance of EPA recommended treatment process (i.e. traditional standard drain field) for OSWT. The UCF research group also performed an experiment to understand the efficiency of traditional standard drain field. At the same time the research group developed an innovative wastewater treatment process named B & G treatment bed as a comparison with traditional standard drain field. This paper mainly focuses on performance of these two treatment processes. The B & G is a novel treatment process by its functionality for nutrient removal. The process generally used a media mixture developed by the research group of UCF. This mixture will act as organic carbon source to support denitrification process while nitrification process does not demand such carbon source. Evan it is observed that this mixture can remove nutrient by physical-chemical process. The recirculation sand filter (RSF) of traditional drain field is also filled by another mixture of media. Both media mixtures are developed by batch experiment in UCF laboratory. The performance of the B & G is compared with the traditional treatment process practiced in USA. These media mixtures can be good supporting media for microorganisms' growth and development. All the major nitrogen and phosphorus species removal is observed by collecting sample in a weekly fashion. The pathogens removal efficiency is also observed. The sample is analyzed by a certified laboratory (i.e. Environmental Research and Design, ERD) in Orlando, Florida to maintain the best quality of this research. The presence of microorganisms is identified by using PCR. The B & G drainfield is very effective for removing both nitrogen and phosphorus species from wastewater. It is also very efficient to remove pathogens too. Standard drainfield is very effective for pathogen removal but it cannot remove nutrients effectively. Nitrate removal in B & G drainfield is well compared to standard drainfield.
Book Synopsis Evaluation of Onsite Preanoxic Recirculating Gravel Filter Wastewater Treatment Systems for Nitrogen Removal by : Stephany Wei
Download or read book Evaluation of Onsite Preanoxic Recirculating Gravel Filter Wastewater Treatment Systems for Nitrogen Removal written by Stephany Wei and published by . This book was released on 2013 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 25 percent of the United States population is served by conventional onsite wastewater treatment systems (OWTS), which consist of a septic tank followed by a soil adsorption field with subsurface effluent dispersion. OWTS have limited nitrogen removal ability, and in some locations their nitrogen loading contributes to eutrophication and impairs groundwater for potable uses. Consequently, there is a need for OWTS with improved nitrogen removal efficiency. The design of onsite nitrogen removal systems should be simple with minimal mechanical equipment and chemical addition. These systems should also require very little operating attention and provide reliable nitrogen removal performance under varying household load conditions. This study evaluated the long-term performance of two new designs intended to meet these requirements while also producing an average total nitrogen effluent concentration of less than 20 mg/L. The designs tested were modifications of recirculating gravel filters (RGF), which have been used for many years. RGFs are easy to operate and are proven to be highly effective for the removal of organic pollutants such as biochemical oxygen demand (BOD) and total suspended solids (TSS), as well as biological oxidation of ammonia to nitrate. The modified RGF systems included an anoxic zone below the normal aerobic zone in which flow from the upper zone contacted septic tank effluent flow to promote biological denitrification for nitrogen removal. The systems were considered passive nitrogen removal systems because they do not require an exogenous carbon source. The differences between the two system designs included one having a vegetated aerobic zone (Vegetated RGF) and the other having a layer of oyster shells at the top of aerobic zone, and a different anoxic zone inlet design and upflow flow pattern (Enhanced RGF) versus a horizontal anoxic zone flow pattern for the Vegetated RGF. Each system treated 480 gallon/day of domestic wastewater with a typical diurnal flow pattern. Their performance was evaluated for twelve months, which also included five stress tests that simulated extreme wash loads conditions, low loading periods, vacation interruptions, and power failure that might occur for a single home. This research evaluated and compared the performance of these systems in regards to nitrogen, BOD, TSS, total phosphorus (TP), and fecal coliform removal. Their responses to the stress tests and the effect of temperature were also assessed. The Vegetated RGF achieved high average treatment efficiencies for BOD (98%), TSS (99%), and fecal coliform (1.4 log reduction). The Enhanced RGF was equally effective at removing BOD (97%), TSS (99%), and fecal coliform (1.1 log reduction). Both systems achieved a total phosphorus removal efficiency of about 40 percent. The effluent annual average total nitrogen concentrations were 15.2 and 8.6 mg/L with 95th percentiles of 18.5 and 12.3 mg/L for the Vegetated RGF and Enhanced RGF systems, respectively. Both the Vegetated and Enhanced RGF systems had good nitrification efficiency, but some operational clogging in the feed distribution piping did cause higher effluent ammonia concentrations. The larger aerobic volume and lower nitrogen loading to the Vegetated RGF system provided a higher nitrification efficiency compared to the Enhanced RGF. A much greater denitrification efficiency was observed for the Enhanced RGF system compared to the Vegetated RGF system due to its improved method of contacting the nitrified flow from the upper aerobic zone and the septic tank effluent.

Book Synopsis Soil-based Wastewater Treatment by : Jose A. Amador
Download or read book Soil-based Wastewater Treatment written by Jose A. Amador and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our book addresses the needs of practitioners, engineers, scientists, regulators, resource managers, planners, and others with a need to know about septic systems. It arose after discussions about the need for a text that integrated current understanding of the hydrologic, physical, chemical, and biological processes involved in the treatment of wastewater using soil. In our experience, people working with septic systems – ourselves included – have a fragmented understanding of what these systems are, how they function, how wastewater moves through soil, how and which pollutants are removed, and how these systems impact the environment and public health. The relevant information is scattered across disciplines, information sources and audiences. This book is an attempt to collect and integrate this information in one place, and provide a scientific framework for understanding soil-based wastewater treatment.

This book was released on 2017-06-15 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
