  A constructed wetland composed of a pond- and a marsh-type wetland was employed to remove nitrogen (N) and phosphorus (P) from effluent of a secondary wastewater treatment plant in Korea. Nutrient concentrations in inflow water and outflow water were monitored around 50 times over a 1-year period. To simulate N and P dynamics in a pond- Cited by: 9.

In the recent past years, micropollutants that are pharmaceutically active compounds (PhACs) have been used extensively and have been discovered in raw sewage, wastewater treatment plants, effluents, surface, and groundwater with concentrations from ng/L to several μg/L.

CONTROL OF NUTRIENTS IN MUNICIPAL WASTEWATER EFFLUENTS VOLUME I: PHOSPHORUS Proceedings of an International Seminar San Diego, California September , Seminar Convener: E. F. Barth Wastewater Research Division Municipal Environmental Research Laboratory Speakers: Dr. N. W. Schmidtke, Burlington, Canada Dr. J. V. DePinto, .   In the tertiary treatment (coagulation–flocculation–disinfection for irrigation reuse) of a secondary wastewater treatment plant effluent, removal percentages for BOD 5 and COD (initial BOD 5 and COD concentrations were (± ) mg/L and (± ) mg/L, respectively) was obtained to be 46% and 39%, by:   In order to achieve phosphate recovery from the secondary effluents of an urban wastewater (biological) treatment plant, the adsorption onto single iron (GFH, Bayoxide and FeOOH) and onto binary iron-manganese (AquAsZero) oxy-hydroxides, as well as the ion exchange by using Purolite AEMBCL resin, were investigated as post-treatment by: 9.   In addition, the pilot plant treating crude sewage with and without fortification with primary sludge to achieve constant OLR and an HRT of h (OLR of kg COD m 3 d −1) and an HRT of h (OLR of kg COD m 3 d −1) also showed some beneficial improvements in removal at the higher HRT for E1 and E2 (Table 2).Cited by: 2.

Jamie Kapitain Septem Introduction. Sewage is polluting Ontario’s lakes and rivers. Provincial Auditor Erik Peters concluded in his annual report that effluents from 24 percent of Ontario’s sewage treatment plants (STPs) fail to meet health and environmental guidelines. 1 The offending plants pose a danger to the environment and to the health of Ontario residents. The contaminated wastewaters, especially wastewater treatment plant (WWTP) effluents, are considered as a major source of PFCs to natural water (Boulanger et al. ; Pan et al. ). For PFCs released from WWTP effluents, there is an increasing concern on their potential for contaminating surface and underground water (Huset et al. ).Cited by: 6.   Enhanced Biological Phosphorous Removal: Wastewater Treatment EPBR uses bacteria to store and remove phosphorus from wastewater by storing it in their cells. Nitrogen Removal in Municipal.   For example, gemfibrozil and sulfamethoxazole, two compounds that are poorly removed in wastewater treatment plants, showed better removal in the presence of labile organic carbon derived from wetland plants than in the presence of the labile dissolved organic carbon in wastewater effluents (Lim et al., ).Cited by:

[John Bentley Nesbitt; Soap and Detergent Association. Phosphate Research Committee.]. This valuable new book offers practical guidance regarding the design and operation of systems for reducing effluent nitrogen and phosphorus.

The principles of nitrogen and phosphorus removal are discussed, including sources of nitrogen and phosphorus in wastewater, removal options, nitrogen and phosphorus transformations in treatment, process selection, and 5/5(3).

An efficient removal of this constituent from the effluent of municipal wastewater treatment plants has been of growing interest. Alum salts (AlCl 3, Al 2 (SO 4) 3) and iron salts (FeCl 3, FeSO 4) are the commonly used chemical coagulants for the removal of phosphorus.

The aim of the present work was to evaluate the coagulation performances of the four coagulants by treating Cited by: 1. ► Treatment of municipal wastewater effluent using microalgal biofilms.

MUNICIPAL & INDUSTRIAL WASTEWATER TREATMENT Phosphorus Removal As regulations become more stringent, removing phosphorus/phosphates from wastewater effluents is easily accomplished by the addition of a metal coagulant.

The most common are aluminum and iron based. However, finding the correct chemistry for your specific application.

Municipal wastewater treatment plants (WWTPs) are a crucial part of modern water pollution control, however many developed regions have recognized the limitations of WWTPs in the removal of various pollutants, resulting in effluents being a potential source of aquatic pollution (Lowenberg et al.

The principles of nitrogen and phosphorus removal are discussed, including sources of nitrogen and phosphorus in wastewater, removal options, nitrogen and phosphorus transformations in treatment, process selection, and Cited by: Phosphorus is a pollutant in aquatic systems because it promotes eutrophication which results in the bloom of aquatic plants, growth of algae and depletion of dissolved oxygen.

Phosphorus removal from wastewater effluents, using chemical and biological treatments Cited by: 8. Abstract. As with other organisms, phosphorus is an essential element for aquatic plants. It is a component of molecules such as the nucleic acids and adenosine triphosphate (ATP) involved in the vital processes of enzyme synthesis and energy transfer and its compounds play a basic rôle in the mechanisms of photosynthesis by which these plants act as the primary producers of.

Energy-producing wastewater treatment plants increasingly rely on phosphorus removal using iron, but the problem (as in current processes) is the subsequent recovery of phosphorus.

Enhanced Biological Phosphorus Removal (EBPR) Process Description Conventional activated sludge microorganisms (mixed liquor suspended solids, or MLSS) contain to Chemical addition, with filtration or membrane separation, is commonly used to meet these low targets and therefore most of the effluent P from tertiary P removal facility is in the soluble phase.

Our study examined the bioavailability of phosphorus (BAP) in the effluents of advanced phosphorus removal treatment systems using algal bioassay experiments. Acid mine drainage (AMD) sludge, a waste product from coal mine water treatment, was used in this study as an adsorbent to develop a cost-effective treatment approach to phosphorus removal from municipal secondary by: CSTR tests with three types of water (synthetic wastewater, river water, and municipal secondary effluent) illustrated that P adsorption by AMD sludge was relatively independent of the presence of.

Moreover, sequencing batch operation of MBBR has been attempted for biological phosphorus removal (Helness, ; Pastorelli et al., ), how-ever, documents and practical experiences with simultaneous nitrogen and phosphorus removal in the.

CSTR tests with three types of water (synthetic wastewater, river water, and municipal secondary effluent) illustrated that P adsorption by AMD sludge was relatively independent of the presence of other ionic species.

In treating municipal secondary effluent, a phosphorus removal efficiency in excess of 98% was by:   Volatilization of ammonia due to increase in pH is not a dominant contributor to overall removal efficiency. Total phosphorous removal rates reached % and % for untreated and autoclaved secondary effluent, respectively.

Ammonia removal rates reached % and % for untreated and autoclaved secondary effluent, by: 5. denitrification and phosphate removal occurred in a bioreactor filled with synthetic wastewater and packed with iron and wood and allowed to react over a long-term [10].

Phosphorus is often the limiting nutrient that controls eutrophication. Municipal wastewater treatment plants contribute approximately 5% of the environmental phosphorus loading and onsite wastewater is estimated to contribute 4 – 35% (Lombardo, ).

To reduce the release of pharmaceuticals and endocrine disruptors into the aquatic environment or to remove them from wastewater intended for direct or indirect reuse, the application of advanced wastewater treatment may be required.

In the present study, municipal wastewater effluents were treated with ozone (O3) in a pilot-scale plant consisting of two bubble columns.
