Biological Phosphorus

The way excess sludge must be disposed of is a key factor in the choice of the appropriate phosphorus removal technique at municipal wastewater treatment plants. In Europe the ongoing trend of tightening the sludge spreading rules called for a serious reduction of its agricultural utilisation and the expansion of the (co-)incineration disposal route, which led to a shift towards more sophisticated sludge handling techniques. This paper illustrates the impact of different sludge handling techniques on the performance of chemical and enhanced biological phosphorus removal at municipal WWTPs. The main conclusion is that although enhanced biological phosphorus removal is particularly sensitive to the problem of return liquors from sludge treatment processes indirect dewatering and anaerobic stabilisation cannot be discarded altogether when considering its implementation.

An additional module for the prediction of enhanced biological phosphorus removal is presented on the basis of a calibrated version of ASM3. The module uses modified processes from ASM2d but neglects the fermentation of readily degradable substrate. Biomass decay is modeled in the form of endogenous respiration as in ASM3. The glycogen pool and biologically induced P-precipitation is not taken into account. The module was systematically calibrated with experimental data from various batch experiments, a full-scale WWTP and a pilot plant treating Swiss municipal wastewater. A standard parameter set allowed all data to be simulated.

Chesapeake Bay Watershed

The performance and economics of four recently constructed or modified BNR municipal wastewater treatment plants located in the Chesapeake Bay Watershed, USA were evaluated, and compared to a treatment plant implementing chemical phosphorus removal and complete nitrification. Phosphorus removal has been very reliable to effluent concentrations below 0.5 mg/L without chemical addition or effluent filtration at BNR plants that have been operating for more than two years. Significant variation was observed in the wastewater characteristics, and this has affected biological phosphorus removal. Chemical precipitation effluent TP concentrations have averaged less than 0.1 mg/L.The small BNR plant was clearly the most costly to operate per 1000 m3/d of flow, which illustrates economy of scale. The chemical precipitation plant was generally more expensive to operate than the large BNR plants.

This article investigates the efficiency of phosphorus removal in the municipal wastewater treatment plants in five counties of Romania from 2013 to 2017. This study focused on evaluation of the performance of phosphorus elimination using biological methods in order to respect the admissible effluent discharge limits. The yearly average of inflow total phosphorus varies from 3.64 mg/L to 4.22 mg/L comparing with 1.02 mg/ L and 1.59 mg/L the average of outflow. Chemical and biological methods are utilized to remove phosphorus. The efficiency of the numerous process available for the phosphorus removal is quite inadequate by comparing the effluent degree of purification and the removal cost.
