Phosphorus And Nitrogen Removal From Municipal Wastewater

phosphorus and nitrogen removal from municipal wastewater

The internal nitrogen to phosphorus ratio decreased from 23:1 to 11:1 when increasing the loading rate. This combination of findings demonstrates that microalgal biofilms can be used for removing both nitrogen and phosphorus from municipal wastewater effluent.

Chlorella vulgaris was used for the removal of residual ammonia/ammonium ion (NH 3 /) and orthophosphate ion from secondary wastewater effluent collected from a municipal wastewater treatment plant. The uptake rates for nitrogen and phosphorus were studied with different initial algal cell densities and the addition of CO 2 gas for pH control and supply of inorganic carbon.

Phosphorus and nitrogen removal from municipal wastewater ...

Biological nutrients removal (BNR) has been widely applied in the municipal wastewater treatment plants (WWTPs) to remove phosphorus and nitrogen. However, the shortage of organic substrates in domestic wastewater poses a severe obstacle for BNR processes, while large quantities of waste activated sludge (WAS) are inevitably produced in WWTPs and the related treatment processes are costly. Ironically, WAS contains high levels of organic substances (such as proteins and polysaccharides) that ...

Advanced nitrogen removal from municipal wastewater ...

phosphorus and nitrogen removal was studied with dif-ferent mathematical models. For nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic units in four separate reactors that were operated continuously at different loading rates of phosphorus and nitrogen and different hydraulic retention times. Under optimum conditions, almost complete ...

Phosphorus and Nitrogen Removal from Municipal Wastewater ...

Wastewater contains nitrogen and phosphorus from human waste, food and certain soaps and detergents. Once the water is cleaned to standards set and monitored by state and federal officials, it is typically released into a local water body, where it can become a source of nitrogen and phosphorus pollution. Some wastewater treatment plants are able to remove more nitrogen and phosphorus from ...

Phosphorus and Nitrogen Removal from Municipal Wastewater ...

Kim et al. demonstrated high removal efficiencies for COD (86%), total nitrogen (93%) and total phosphorus (83%) from untreated municipal wastewater in an algae dominated consortium in a HRAP. Critical parameters, such as light intensity, photoperiod, temperature and pH affect HRAP wastewater treatment and biomass production.

Nitrogen and Phosphorous Removal in Municipal Wastewater ...

Use of nitrogen- and phosphorus-based synthetic fertilizers shows an increasing trend, but this has led to large-scale influx of reactive nitrogen in the environment, with serious implications on human health and the environment. On the other hand, phosphorus, a non-renewable resource, faces a serious risk of depletion. Therefore, recovery and reuse of nitrogen and phosphorus is highly desirable.

Phosphorus and Nitrogen Removal from Municipal Wastewater ...

Phosphorus removal. The effectiveness of phosphorus removal during wastewater treatment can vary, depending on the available equipment and the treatment methods used. Only wastewater treatment plants that employ specialised phosphorus removal techniques will normally be able to remove phosphorus to the desired levels.

Phosphorus Treatment and Removal Technologies

Nitrogen and phosphorus are essential to the growth of microorganism, plants, and animals, so that, they are known as major nutrients. The removal of nutrient before discharging treated wastewater is desirable not only to prevent eutrophication, but for reuse purposes. In Iraq, Due to the insufficient water supplies in recent years, the wastewater Authority’s initiate a new program aiming at ...

Conventional nitrogen removal is performed in multiple stages. Wastewater ammonia (NH3) is oxidized to nitrite by autotrophic ammonia-oxidizing bacteria (AOB), and the nitrite is then oxidized to nitrate by nitriteoxidizing bacteria (NOB) under aerobic conditions. Two additional steps are required to convert the nitrate into inert nitrogen gas ...
