The need to control and remove phosphorus (P) in discharges from waste water treatment facilities (WWTF) to prevent eutrophication of receiving waters is well known. Regulatory initiatives are further contributing to the addition of stringent P limits to discharge permits. Accordingly, many agencies are facing increasingly stringent standards of effluent P and as a result the effluent limit of 0.1 mg P/L total phosphorus (TP) or lower is being achieved. Since the reliable performance limit of enhanced biological phosphorus removal (EBPR) is commonly accepted at about 0.1 mg P/L in the dissolved form, these facilities will need to utilize tertiary chemical phosphorus removal (CPR) to reliably achieve limits lower than 0.1 mg P/L (ultra-low limits) (Pagilla and Urgun-Demirtas, 2007). The mechanistic basis for P removal using chemical precipitant addition is generally considered to be more than simple precipitation. The role of adsorption and/or surface complexation in removal of reactive or unreactive phosphorus to the already formed chemical precipitates or complexes has been reported. Omoike and VanLoon (1999) showed that the most likely mechanism involves sorption of P species on Al(OH)3(s) formed by Al salt addition to water for P removal, and further precipitation/complexation of P onto the Al hydroxyl precipitate for additional P removal. In tertiary P removal, usually a non-stoichiometric dose or several times stoichiometric dose of the precipitant is needed. The chemical precipitates formed upon addition of such high doses of chemical precipitant are likely to serve as nuclei for further aggregation of newly formed precipitates, thus enhancing the overall tertiary P removal. The excess precipitant added to the secondary effluent produces hydroxyl precipitates which could serve as adsorbents for additional P removal. It is well proven that alum sludge from water treatment plants have high capacity for wastewater effluent P removal depending on their structure and/or age of the sludge solids. The role of mixing, pH, contact time, precipitated solids concentration in the mixing tank, and feed secondary effluent characteristics could influence this process of tertiary P removal. The investigation of such variables and the process along with careful analytical measurements would explain the basis for precipitation/solids contact P removal from wastewater effluents. Such information could be used to enhance the process and optimize the operating conditions of tertiary P removal by chemical addition. This paper presents full scale and lab scale investigations of some of the above listed parameters on tertiary P removal with specific focus on role of precipitated solids in enhancing P removal and/or reducing the dose of precipitant to be added to achieve the desired P removal. The study was conducted at the Iowa Hill Water Reclamation Facility (WRF) and Farmers Korner WWTF in Breckenridge, CO, and at the Illinois Institute of Technology.

Biomonitoring of water quality is very much essential for assessing the overall health of water bodies and safe supply of drinking water. The chemical nature of toxicant is highly dynamic in environment with time and space whereas biological system can integrate all environmental variables over a large period of time in terms of effect that can be easily measured and quantified. In view of the above, there is a pressing need to determine the water quality of natural resources as well as drinking water based on the standard protocols and guidelines from regulatory agencies.It is clear that the synthetic chemicals are essential for our society to maintain the health and well being of the people. However, there has been a range of detrimental effects on human health and natural environment. In general, we need to improve our management of waste chemicals discharged into the air, water and soil environments. New techniques are needed to predict adverse effects before they occur and for the treatment of wastes. In addition, a range of social, political and economic factors will be needed to be taken into account in order to achieve success.

This guidance document incorporates the systematic approach for integrated capacity assessment of a wastewater treatment plant and identifying performance limiting factors. Based on evaluation by the project team, this document presents the “best-practices” approach that defines a systematic process for applying analytical methods and testing tools to optimize and upgrade wastewater treatment plants. This guidance document suggests a systematic approach for capacity evaluation, which has three generalized stages: desktop evaluation as an initial plant assessment; detailed evaluation for individual unit process analysis and testing, along with integrated evaluation of the whole plant; and field scale testing as confirmative testing for implementation of corrective actions. The document covers analysis, testing methods, and protocols for plant monitoring. It describes the integrated hydraulics and process modeling approach for determining plant capacity. The document addresses currently practiced treatment processes, evaluation tools, and equipment in the industry. Individual unit processes in liquid treatment and solids handling are illustrated with detailed process analysis and testing, performance limiting factors, approaches for overcoming potential constraints, capacity assessments, and case studies. The document also provides recommendations and sources of detailed information for testing procedures.

This project addresses the dissolved organic nitrogen (DON) content in the effluents of different wastewater treatment plants (WWTPs). In this report, information is presented on the occurrence and levels of DON in WWTP effluents and its bioavailability. The information presented was generated by a survey of existing data from full scale plants achieving TN removal, direct sampling and monitoring of effluents from selected plants, and laboratory investigations on DON production in biological processes of WWTPs and its bioavailability to algae and bacteria. The results showed that there is a wide variation in effluent DON at different plants, ranging from non-detectable levels to as high as 2.5 mg N/L. The DON fraction of the effluent TN increases with decrease in effluent TN values, and could be as high as 85% of effluent TN. Size fractionation of effluent organic nitrogen (ON) fraction passing through a 1.2 µm filter showed that a significant colloidal fraction of ON exists between 0.1 and 1.2 µm particle size range in some plants. A fraction of the effluent DON is readily bioavailable to algae and bacteria in laboratory bioassays, and the presence of both algae and bacteria species in the bioassay increases the bioavailable DON fraction.

This project addresses the successful nitrogen and phosphorus removal technologies being implemented at existing wastewater treatment plants (WWTPs), some key challenges and knowledge gaps in implementing technologies, research needs to improve the existing methods and technologies to achieve low total nitrogen (TN) and total phosphorus (TP) effluents (TN <5 mg/L and TP< 0.5 mg/L). Technology and cost assessment of successful technologies for TN and TP removal on a sustainable basis was accomplished by using a “threshold limit” approach to categorize technologies for different effluent TN and TP limits based on desired criteria. Membrane-based process applications were selected among advanced treatment processes for N and P removal from wastewater at pilot and lab scale technology demonstration studies. The investigations included membrane bioreactor application for N and P removal from wastewater, centrate treatment, and to achieve simultaneous nitrification and denitrification. The results indicated membrane based applications are attractive methods for achieving low TN and TP effluents, but supplementary chemical addition is needed depending on the wastewater characteristics. Full scale implementation of step feed BNR with chemical P removal was demonstrated as a successful technology transfer application at John Egan Wastewater Reclamation Plant of Metropolitan Water Reclamation District of Greater Chicago (MWRDGC).
