The objective of this paper is to show the usefulness of multivariate statistical techniques to structure and visualize the information contained in multi-criteria matrixes obtained from the evaluation of control strategies in wastewater treatment plants (WWTP). The performance of sixteen different control strategies is evaluated by measuring their degree of satisfaction for twenty-four environ...

The poster deals with an integrated methodology for the assessment of the impacts of alternative sewer and waste water treatment plant (WWTP) management scenario’s on the quality of the receiving waters. The input time series for the flows and concentrations at the combined sewer overflow (CSO) structures and at the treatment plant intake are obtained through a continuous sewer simulation model...

This paper presents a case study that explores the advantages that can be derived from the use of a design support system during the design of wastewater treatment plants (WWTP). With this objective in mind a simplified but plausible WWTP design case study has been generated with KBDS, a computer-based support system that maintains a historical record of the design process. The study shows how,...

The energy content of wastewater is routinely assessed by chemical oxygen demand (COD) measurements that only provide an incomplete picture and the data fundament of other energy parameters remains scarce. The volumetric heat of combustion (ΔCH) of raw wastewater from a municipal wastewater treatment plant (WWTP) was assessed using oven drying method (ΔCHvol = −6.8 ± 4.3 kJ L, n = 20) and freez...

Abstract Water scarcity and the lack of treatment systems for regeneration discharge have an alternative design wastewater plants, WWTP. In this context, it is explored to integrate photovoltaic energy a web system automation control according Mexican official standards. For this, model WWTP proposed, with solar panels, use that uses PHP programming language javascript input output management e...

We monitored the effects of wastewater treatment plant (WWTP) inputs on the recovery of stream biofilmsafter a large flood event that eroded most of the former biofilm communities. We monitored biomass recovery,chlorophyll a, nitrogen content, and stable isotope natural abundance(15N) over 8 weeks in lightand dark-exposed biofilms upstream and downstream from WWTP inputs, respec...

It is generally known that there are many endocrine disrupting compounds (EDCs) in the effluents from wastewater treatment plants (WWTPs). Most research has focused on the occurrence of estrogenic or androgenic activities, while ignoring that there are environmental chemicals disrupting thyroid system, which is essential for growth and development in both humans and animals. In the present work...

The paper describes linear and nonlinear modeling of the wastewater data for the performance evaluation of an up-flow anaerobic sludge blanket (UASB) reactor based wastewater treatment plant (WWTP). Partial least squares regression (PLSR), multivariate polynomial regression (MPR) and artificial neural networks (ANNs) modeling methods were applied to predict the levels of biochemical oxygen dema...

Ever-tightening regulations on releases to the environment have become a major business factor for the chemical industry. The Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF) effluent guidelines have required many manufacturing sites to expand or upgrade their wastewater treatment plants ("P) at considerable cost. Du Pont has recognized the need to shift the emphasis from "end-of-pipe'...

Pharmaceuticals and personal care products (PPCPs) are emerging contaminants that have been found ubiquitously in wastewater and surface waters around the world. A major source of these compounds is incomplete metabolism in humans and subsequent excretion in human waste, resulting in discharge into surface waters by wastewater treatment plant (WWTP) effluent. One pharmaceutical found in particu...
