Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus in surface runoff from agricultural lands is often implicated in the degradation of surface water quality. Many states are developing soil phosphorus application limits. Utilities must develop and implement new best management practices (BMPs) to control phosphorous. The objective of this project was to investigate the beneficial use of water treatment residuals (WTRs) to control non-point source (NPS) phosphorus pollution and protect surface water quality. Specifically, the researchers planned to examine the unique chemical characteristics of WTRs, namely the large concentration of aluminum and iron hyrdroxides, to combine them with phosphorus in high phosphorus soils, biosolids, and manures to reduce the likelihood of phosphorus release to aquatic environments. Several types of WTRs were selected and characterized based on the coagulant used (aluminum and iron based) and their form - dewatered or liquid. The research developed valuable new insight for the beneficial use of WTRs and demonstrated WTRs' potential as a BMP for phosphorus control in surface runoff from agricultural lands and for protecting surface water quality. In particular, the potential role of WTRs in Phosphorous Index programs was confirmed. Future research and full-scale demonstrations are needed to confirm the potential of land applied WTRs as a BMP for phosphorus control in runoff from agricultural lands. Land application of WTRs within a utility?s source water watershed, while subject to local and state regulations, can be implemented as part of an overall watershed protection program.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Incorporation of Al-WTR to a depth of 10 cm decreased SP concentrations in subsurface flow and leachate by 37 and 11%, respectively. However, with incorporation of Al-WTR to a depth of 20 cm, both subsurface flow and leachate SP concentrations were reduced by approximately 90%. The incorporated Al-WTR reduced soil water-extractable P (WEP) by approximately 70%. However, Mehlich-1 P concentrations were not affected by the incorporation of Al-WTR in the soil. Care must be taken to ensure complete incorporation of Al-WTR throughout the P-impacted layer, as Al-WTR is only effective in reducing SP concentrations when it is in contact with the impacted soil. Shoot and root growth of stargrass were not adversely affected by the Al-WTR applied at a rate of 2.5% of soil weight.

Available in PDF, EPUB and Kindle. Book excerpt: This research report presents the results of a study to determine both the longlasting effects of a single WTR-biosolids co-application (applied in 1991) and the short-term impacts of a repeated WTR-biosolids co-application (applied in 2002) on native rangeland soil phosphorus dynamics. This report covers from the time of application (1991 or 2002) along with changes between sampling periods, with field soil sampling occurring in October 2003 and October 2004. Specifically looked at were quantify changes in inorganic soil P associated with a single or repeated WTR-biosolids co-application and identify which inorganic P phase dominates using a sequential extraction technique along with same for organic soil P.
Download or read book Drinking Water Treatment Residuals for Removal of Phosphorus in Agricultural Runoff written by Beth Kondro and published by . This book was released on 2024 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excess nutrient loading to the Great Lakes Basin from agricultural runoff has negatively impacted water quality, resulting in harmful algal blooms. Best management practices, including constructed wetlands and sedimentation basins, can be used to reduce phosphorus losses from agricultural fields. Constructed wetlands are efficient in the removal of particulate phosphorus; however, removal of dissolved phosphorus is limited and requires further treatment to improve surface water quality. Several types of filter media (composed of Ca, Fe, and/or Al) can be used to further reduce the amount of dissolved phosphorus that enters surface water, and a media consisting of low-cost waste residual would be beneficial to adoption. Drinking water treatment residuals (DWTR) that often contain Al could be reused as an adsorbent for dissolved phosphorus. We evaluated the use of modified drinking water treatment residuals for removing dissolved phosphorus from wastewater. DWTR were mixed with binders, made into pellets to create an insoluble media with mechanical strength, and pyrolyzed to create a reactive media pellet. Pellets were evaluated using flow through columns and included experiments to determine the impact of pH (i.e. 6, 8, and 10), retention time (i.e. 1, 5, and 10 min), and field-collected agricultural runoff on dissolved P removal. Cement was found to be the best binding material to create an insoluble pellet with mechanical strength. The P removal capacity of the pellet consisting of the cement binder (1,397 mg P/kg) was within the range of previously evaluated steel slag (120-10,210 mg P/kg), a common reactive media for P removal. The addition of drinking water treatment residual and metals decreased the P removal capacity of the cement binder at pH 6-1 min retention at exhaustion. Increasing retention time increased the P removal capacity of the filter media tested. Wastewater pH has a minimal impact on the P removal capacity of all media except the pyrolyzed DWTR + cement binder media. Evaluated media was negatively impacted by real agricultural runoff with a measured decrease in P removal capacity (43-146 mg/kg decrease) compared to P-spiked distilled water at the same retention time. The pyrolyzed cement pellet was the most cost-effective reactive media, due to an increased P removal capacity. Pyrolyzed DWTR + cement binder would be more costly than the pyrolyzed cement binder alone but could provide a solution for the disposal of DWTR.

Undercoffer and published by . This book was released on 2009 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Applications of manure and soils with elevated amounts of phosphorus (P) can result in surface transport of P leading to eutrophication of surface waters. Drinking water treatment residuals (WTR) have been identified as a potential best management practice to reduce the loss of P from agricultural fields. Two field simulated rainfall studies were used to investigate the efficacy of WTR to reduce P transport, reduce soil test P (STP), and determine if relationships between STP and runoff dissolved P (RDP) are altered by soil applied WTR. In the first field study, WTR was co-blended with poultry litter to achieve a range of phosphorus to aluminum molar ratios, or phosphorus saturations (Psat), two weeks prior to land application. Blending WTR at rates of 0, 7, 21, 84 g WTR kg-1 manure resulted in phosphorus saturations of 1860% (0WTR), 600% (LWTR), 200% (MWTR) and 50% (HWTR), respectively. Manure soluble P was reduced by 33, 62, and 96% by the LWTR, MWTR, and HWTR, respectively. The treatments were broadcast at 11.3 Mg ha-1 on field plots (2m X 2m) and simulated rainfall was performed prior to, immediately following application and at 1 month intervals for 3 months. Immediately following treatment application, RDP was reduced by 68% by the MWTR treatment and 97% by the HWTR treatment when compared to the RDP of the 0WTR treatment (32.9 mg L-1). These large reductions relative to previous research suggest co-blending WTR with manure prior to land application, rather than broadcasting each material separately, may be a more effective use of WTRs P-binding capability. Currently, Ohio's P-index uses total manure P as an indicator of P transport risk. Results of this study show that the P-index should be adjusted for WTR treatments. Phosphorus source coefficients determined by soluble manure P is currently used by several states and could be used in Ohio to reflect reduced P transport from WTR co-blending. Co-blending WTR with manure to achieve a final blended Psat 100% may provide the best protection of water quality and be a useful tool for WTR/manure co-blending calibration. In the second field simulated rainfall study, WTR (10 Mg ha-1) was incorporated into field plots (2m x 2m) with a wide STP range. Soil incorporated WTR reduced STP for all soil test methods following WEP (74.8%) Psat (50.2%)> M3P (40.2%)> B1P (39.5%) and RDP (39.4%), one day after WTR application. We observed positive linear relationships between Mehlich-3 P (M3P), Bray-1 P (B1P), water extractable P (WEP), and phosphorus saturation (Psat) with RDP for all runoff events. Relationships between M3P, B1P, or Psat and RDP were not significantly altered by soil incorporated WTR while the relationship formed by WEP and RDP had a significantly higher slope when soil incorporated WTR was present. Ohio's P-index currently utilizes B1P and M3P as an indicator of environmental risk of P transport. Results from this study support the use of B1P and M3P to categorize P transport risk, regardless of previous WTR applications.

This book was released on 1996-01-01 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potable water treatment processes produce safe drinking water and generate a wide variety of waste products known as residuals, including organic and inorganic compounds in liquid, solid, and gaseous forms. In the current regulatory climate, a complete management program for a water treatment facility should include the development of a plan to remove and dispose of these residuals in a manner that meets the crucial goals of cost effectiveness and regulatory compliance. This comprehensive water treatment residuals management plan should involve the: 1) Characterization of the form, quantity, and quality of the residuals; 2) determination of the appropriate regulatory requirements; 3) identification of feasible disposal options; 4) selection of appropriate residuals processing/treatment technologies; and development of a residuals management strategy that meets both the economic and noneconomic goals established for a water treatment facility. This manual provides general information and insight into each of these activities that a potable water treatment facility should perform in developing a residuals management plan.

Book excerpt: Increased WTR rates can largely overcome soluble organics impacts and negate the need for massive soil horizon mixing. Al-WTR can be an effective soil amendment to reduce P loss from manure-impacted soil when the WTR is made to contact soluble P in the soil profile. Soluble P not in direct contact with the WTR is unaffected by WTR and is subject to leaching loss.
