How to Tap the Human Infrastructure to Gain Cost Effective Performance and Capacity Benefits at a Wastewater Treatment Plant

In this study, a new, more effective and cost-effective treatment alternative is investigated for the removal of pharmaceuticals from wastewater treatment plant effluent (WWTP-eff). The potential of combining clay with biodegradable polymeric flocculants is further highlighted. Flocculation is viewed as the best method to get the optimum outcome from clay. In addition, flocculation with cationic starch increases the biodegradability and cost of the treatment. Clay is naturally abundantly available and relatively inexpensive compared to conventional adsorbents. Experimental studies were carried out with existing naturally occurring pharmaceutical concentrations found and measured in WWTP-eff with atrazine spiking for comparison between the demineralised water and WWTP-eff matrix. Around 70% of the total measured pharmaceutical compounds were removable by the clay–starch combination. The effect of clay with and without starch addition was also highlighted.

As more and more work is organized through projects and programmers, project management is becoming increasingly important. Aiming to ensure the project quality, control building progress within a short period and make the cost effective, full-process project management for the construction of a large scale modified UNITANK wastewater treatment plant (WWTP) was conducted and introduced in detail in this paper. Long term operation results indicate that the Qianfeng II WWTP shows good pollutants removal performance and stable operation ability, which demonstrates that these project management methods are practical and could be popularized for the similar projects in the future.

Bathing Waters

This study presents a cost-effective analysis by comparing the costs of measures (options) to improve the quality of bathing waters in the Gulf of Kalloni (island of Lesvos, Greece) in order to reduce the anthropogenic eutrophication in the coastal water of the Kalloni Gulf.The Gulf of Kalloni is a semi-enclosed gulf (115 km2) which receives municipal wastewater, agricultural activity drainage, and at times sewage from olive oil plants processing the local olives harvest. The area of study consists of the coastal waters and the river basin of which water run-off drains into the gulf. Four options are comparable in their environmental effectiveness to reduce eurtophication damages which are: municipal wastewater treatment plant, construction of dams, organic farming plus training and olive oil wastewater treatment plant.

Faecal Indicators

Wastewater surveillance is a cost-effective tool for monitoring SARS-CoV-2 transmission in a community. However, challenges remain with regard to interpretating such studies, not least in how to compare SARS-CoV-2 levels between different-sized wastewater treatment plants. Viral faecal indicators, including crAssphage and pepper mild mottle virus, have been proposed as population biomarkers to normalise SARS-CoV-2 levels in wastewater. However, as these indicators exhibit variability between individuals and may not be excreted by everyone, their utility as population biomarkers may be limited. Coprostanol, meanwhile, is a bacterial metabolite of cholesterol which is excreted by all individuals. In this study, composite influent samples were collected from a large- and medium-sized wastewater treatment plant in Dublin, Ireland and SARS-CoV-2 N1, crAssphage, pepper mild mottle virus, HF183 and coprostanol levels were determined. SARS-CoV-2 N1 RNA was detected and quantified in all samples from both treatment plants. Regardless of treatment plant size, coprostanol levels exhibited the lowest variation in composite influent samples, while crAssphage exhibited the greatest variation. Moreover, the strongest correlations were observed between SARS-CoV-2 levels and national and Dublin COVID-19 cases when levels were normalised to coprostanol. This work demonstrates the usefulness of coprostanol as a population biomarker for wastewater surveillance studies.

The Eu

In co-ordination with the EU-guidelines the large wastewater treatment plants in Switzerland have to be extended with enhanced nitrogen removal. Denitrification in tertiary filtration is a cost-effective alternative to extended denitrification in the activated sludge system, which needs additional reactor volume. At the wastewater treatment plant Zürich-Werdhölzli full-scale experiments of denitrification with methanol in tertiary filtration were performed during a summer and a winter campaign of 4 months each. For this purpose one of the original 22 filter cells was equipped with a methanol dosage. At temperatures of 12-15°C rates of denitrification of about 1.0 kgN m−3 d−1 are attained. After main backwashing, denitrification is significantly reduced. Frequent backwashings (several times per day) led to methanol breakthroughs due to biofilm loss. The yield coefficient YCOD was 0.4 kg CODX kg−1 CODme. In spite of methanol dosage the quality of the filter effluent was very good during normal operation in the winter campaign. Accumulation of the nitrite intermediate product was observed in summer at temperatures of 20-22°C.
