The SFS-Wetland model used is the wastewater treatment tank belonging to Pertamina Geothermal Lahendong. Based on slope of existing land, it possible design twin gravity wetlands a certain size. This study aimed develop Surface Flow System Constructed Wetland using Monocaria vaginalis, Salvania molesta and Colocasia esculenta, analyze stakeholder perceptions Model, refine this based perceptions...

This paper reported the pollutant removal performances of a hybrid wetland system for the treatment of aquaculture wastewater. The system consisted of two treatment stages: a subsurface vertical flow (VF) wetland, followed by a horizontal flow (HF). The aquaculture wastewater with the different concentrations such as eutrophy and mesotrophy was treated using hybrid constructed wetland. The expe...

In many regions of the world, urban water systems will need to transition into fundamentally different forms to address current stressors and meet impending challenges-faster innovation will need to be part of these transitions. To assess the innovation deficit in urban water organizations and to identify means for supporting innovation, we surveyed wastewater utility managers in California. Ou...

The meat processing industry is one of the largest consumers of total freshwater used in the agricultural and livestock industry worldwide. Meat processing plants (MPPs) produce large amounts of slaughterhouse wastewater (SWW) because of the slaugh‐ tering process and cleaning of facilities. SWWs need significant treatment for a sustainable and safe discharge to the environment due to the high ...

many factors affect wastewater management and utilization plans’ success with any change occurring in any of these factors leading to various feedbacks on other elements of wastewater use system. hence, development of a model with the capability of simulation of all factors, aspects and interactions that affect wastewater utilization indispensable. the objective followed in this study was to mo...

Nested within the typical scope of wastewater infrastructure management lies the hurdle of data transfer. We increasingly rely on the various crews of our authority to collect specific system data, and deliver it to administrative personnel. Due to escalating regulatory requirements, our authority has begun a venture to create a seamless transition between field data acquisition and end user fo...

To develop a better understanding of the issues and best practices related to the use of treated effluent to help maintain river flows and habitat, the Conservancy commissioned a study to summarize the state of the science. The use of treated wastewater effluent is becoming a more prominent factor in Arizona’s overall water management strategy. Treated effluent contains a wide array of chemical...

We propose a traceable approach for the control of the Barcelona wastewater system that is subject to sudden weather-change events within the Mediterranean climate. Due to the unpredictable weather changes, lack of appropriate control methodologies may result in overflow in the sewage system, which causes environmental contamination (pollution). In order to improve the management of the wastewa...

In this paper we propose the use of an argument-based model – ProCLAIM – that has the potential to minimize ecological impact of industrial wastewater discharges into water bodies. On the one hand, the diversity and unpredictability of many of industrial wastewater discharges and on the other, the complexity of ecological systems that finally receive the discharge (i.e. fluvial ecosystems) illu...
