  • DSC: software tool for simulation-based design of control strategies applied to wastewater treatment plants

    This paper presents a computer tool called DSC (Simulation based Controllers Design) that enables an easy design of control systems and strategies applied to wastewater treatment plants. Although the control systems are developed and evaluated by simulation, this tool aims to facilitate the direct implementation of the designed control system to the PC of the full-scale WWTP (wastewater treatment ...

  • Spreadsheet Implementation of Activated Sludge Model #1 for Sequencing Batch Reactors

     KEYWORDS Sequencing Batch Reactor, Simulation Modeling, ASM1, Flow Routing BACKGROUND Many small municipal wastewater treatment plants in North America use sequencing batch reactors (SBR) to provide secondary treatment. SBRs are a fill-and-draw variant of the activated sludge process in which a single reactor is used to mix raw ...

  • Happy Customers, Healthy Business

    As the wastewater treatment industry becomes more competitive, customer service gives businesses the chance to rise above their competitors. Customer service is key in all industries. The water treatment industry is no exception. As the treatment of both drinking water and wastewater becomes a continually more competitive industry, with an ever-growing number of new companies offering ...

  • Modeling Fixed Film Processes: Practical Considerations and Current Limitations from a Consulting Viewpoint

    ABSTRACT Fixed film technologies such as integrated fixed film activated sludge (IFAS), moving bed bioreactors (MBBR), biological aerated filters (BAF) and denitrification filters are gaining popularity in the United States for a number of reasons. As a result, there is a renewed desire to model these processes, particularly for consulting engineers interested in designing these processes. ...

  • Rold Model Water Recycling Program

    ABSTRACTThe Viejas Band of Kumeyaay Indians, a federally recognized tribe, vested with authority by the U.S. Environmental Protection Agency (USEPA), form the Tribal Government to regulate all activities concerning water quality issues within the reservation boundaries. The Reservation has 400 non-transient residents and an average of 5,000 transient residents. The transient population visits the ...

  • Sahara production facility reuses treated wastewater case study

    Repsol Oil Operations has a production facility based in the Sahara region that uses a wastewater treatment system, which not only treats the wastewater from its accommodation, engineering and office blocks, but also reuses the treated effluent for irrigation purposes. This project involved Zulal Water Technology, a Libyan based company with its headquarters in Tripoli, whose primary focus is ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

  • BM Respirometry benefits for activated sludge process management, research and training

    A biological process controlled by non-biological measurements? All treatment plant efficiencies are geared to the waste that they receive. The microorganisms found in the waste need food and oxygen to survive, the food is provided as soluble organic carbon in the waste stream and the oxygen is obtained through the aeration process in the treatment plant. Once a treatment plant ...
