The removal of phosphorus (P) from domestic wastewater is primarily to reduce the potential for eutrophication in receiving waters, and is mandated and common in many countries. However, most P-removal technologies have been developed for use at larger wastewater treatment plants that have economies-of-scale, rigorous monitoring, and in-house operating expertise.

industrial wastewater treatment plants is a key factor in preventingeutrophicationof surface waters. Phosphorous is one of the major nutrients contributing in the increased eutrophication of lakes and natural waters. Its presence causes many water quality problems: • increased purification costs

In long-term operation of CWs for wastewater treatment, substrate sorption contributed the most (approximately 40–70%) to the phosphorus removal (total mass) compared to plant and microbial uptake (Luo et al., 2017; Nguyen et al., 2020). However, substrates have finite sorption capacity, and should be replaced or washed when saturated.

An activated sludge process is commonly used in wastewater treatment, but it is often the case that the effluent from wastewater treatment plants has remaining phosphorus and nitrogen in the form of ammonium and/or nitrate. A post-treatment process is therefore required to remove nitrogen and phosphorus …

Phosphorus and nitrogen are the most important nutrient pollutants (Sun et al. 2020), which have been widely concerned as highlighted indicator for the ecological environment and human health (Wu et al. 2019).The excessive high-load municipal wastewater treatment plants (WWTPs) effluent discharge contributed most of phosphorus and nitrogen emissions which resulted in the high …

Phosphorus entering our lakes and streams comes from "point sources" — piped wastes such as municipal and industrial wastewater treatment plants that release liquid effluent to lakes and rivers or spread sludge on fields; and from natural sources, including past phosphorus loads that build up in lake bottom sediments.

wastewater treatment plants which have demonstrated exemplary phosphorus removal through their treatment processes. The primary goal of this project was to obtain and share information about the technology, performance and costs of applying advanced wastewater treatment for phosphorus removal.

Phosphorus removal from wastewater can be achieved either through chemical removal, advanced biological treatment or a combination of both. The chemical removal of phosphorus involves the addition of calcium, iron and aluminium salts to achieve phosphorus precipitation by various mechanisms which are discussed.

Biological phosphate removal is a relatively new technology dating back to the late 1950s; it wasn't until the 1970s that there were full-scale processes developed for practical use in advanced wastewater treatment. Based on a series of tests and experiments on biological phosphorus removal, Fuhs and Chen (1975) determined that a genus called ...

simulates both biological phosphorus removal and the removal of phosphate through precipitation by metal addition. Given previous detailed and comprehensive studies of the Athens #2 Wastewater Treatment Plant (Liu and Beck, 2000; Liu, 2000), the simulated designs for the wastewater treatment facilities can be driven by crude sewage variations

Phosphorus is present in wastewater and is a pollutant when released into water bodies. It accelerates eutrophication, which can cause serious damage to aquatic ecosystems and water supply (Peng et al. 2018).Phosphorus concentration in domestic wastewater is in the range of 4–12 mg L −1 (Metcalf & Eddy 2014).Within wastewater treatment plants (WWTP), a major source of P is the …

Without the removal of phosphorus from wastewater, the high level of this element would be deadly to aquatic life, plants and wildlife, as well as affecting humans' health. When removing phosphorus from your wastewater it's important to find a company that has extensive experience effectively treating water supplies and safely removing a ...

As phosphorus issues persist, regulations that limit levels in wastewater will become more strict. For many treatment facilities, understanding how to effectively remove phosphorus from their effluent might be a challenge, but it is surely possible. Almost all wastewater treatment plants perform at least a secondary treatment, but this typically does not provide enough phosphorus removal.

Controlling phosphorus emissions from sewage treatment plants is a key factor in preventing eutrophication of surface waters. Regarding surface waters in Germany, the orientation value for the "good ecological status" for total phosphorus (P total) is set at 0.10 mg P total /L. To achieve this value, a further reduction in the P total emissions from sewage treatment plants (STPs) is required.

phosphorous removal rates were possible through biological selection. Today enhanced biological phosphorus removal (EBPR) can increase the biological phosphorus removal rate to 5 percent or more with proper process design and operation. EBPR is a two-step process. In the first step, phosphorous is converted to a soluble form. In the second
