Activated Sludge Model 1 for SBRs

by Water Works Engineers     based in Oakland, CALIFORNIA (USA)

The ASM1-SBR spreadsheet was developed by Water Works Engineers as a means of modeling the performance and oxygen requirements over a single cycle of an SBR. The spreadsheet is based on the IWA Activated Sludge Model 1 and models the dynamic performance of reactor using 15 time steps. For each time step, the user specifies a volume of wastewater ...

Conventional Activated Sludge System

by Biothane - Veolia Water Solutions & Technologies     based in Camden, NEW JERSEY (USA)

The conventional activated sludge system comprises an aeration tank and a clarifier. Aerobic biomass degrades COD in the aeration tank. The mixed liquor (ML) in the clarifier is separated into a water phase and a concentrated ML by sedimentation. The clarified water overflows weirs at the top of the clarifier whereas the sludge (biomass) is ...

Aerobic Wastewater Treatment

by Global Water Engineering (GWE)     based in Bangkok, THAILAND

Aerobic treatment converts the organic pollutants (COD, BOD) in wastewater into a fair amount of excess sludge, and oxidizes the rest with oxygen (air) to carbon dioxide. This causes high operating costs for sludge treatment and disposal and for aeration, so that anaerobic treatment systems are normally to be preferred. The aerobic process ...

Flottweg OSE Decanter - Optimal Sludge Dewatering of Primary and Excess Sludge

by Flottweg SE     based in Vilsbiburg, GERMANY

The decomposition process in a sewage treatment facility continually generates biological sludge. To ensure a stable decomposition process in the biological cleaning stage, this biological sludge must be removed. The removed biological sludge is called surplus activated sludge in further process steps, and it is subsequently transported into a ...

Conventional Activated Sludge

by Entex Technologies Inc.     based in Chapel Hill, NORTH CAROLINA (USA)

Conventional activated sludge (AS) uses suspended biomass to provide a flexible and efficient treatment system. While some AS systems use complete mix basins, a plug flow process with longer narrower basins is more common today. Similarly, while some AS systems still use older coarse bubble diffuser systems, most updated systems use fine bubble ...

Evac - Activated Sludge Plant

by Evac Building sector     based in Cergy-Pontoise Cedex, FRANCE

Effective and reliable waste water treatment is achieved only by correct dimensioning of the technology. It is extremely important to know and be able to control waste water characteristics (concentration, flow, peak loads). Evac’s long experience with waste water characteristics and our ongoing research program give us a clear advantage in ...

THERMO-SYSTEM - Active Solar Sludge Dryer

by Parkson Corporation     based in Fort Lauderdale, FLORIDA (USA)

Parkson’s THERMO-SYSTEMuses the sun as its main power source to generate 95% of the energy required for drying sludge.  The result is significantly reduced operating costs compared to competing technologies like conventional gas or oil fired dryers. The system’s sustainable, drying process is fully automated and is designed with ...

Integrated Fixed-Film Activated Sludge (IFAS) Technology

by CREATECH Aqua ApS     based in Egaa, DENMARK

A cost-effective upgrade solution for existing wastewater treatment plants, the IFAS technology combines the operational characteristics of conventional Activated Sludge (AS) plants with fixed-film technology. In essence, upgrading an AS-WWTP to an IFAS system consists of installing a retention screen (8mm hole size) and adding a certain volume of ...

Activated Sludge Microbiology Poster

by Marshall Environmental Training and Consulting Group, Inc., (METC Group)     based in Corvallis, OREGON (USA)

This 39 in. by 27 in. poster contains 74 photomicrographs of flocs, filaments and protozoa/metazoa plus a Causes of Filaments Table, Ranking Filament Abundance Table and Protozoa Chart. This poster is a serious working tool for operators to help assess floc characteristics; identify filament types, their abundance and cause, identify protozoa and ...

Model ASP-CON - Activated Sludge Plant Controller

by Combined Environmental Technologies Ltd (Ireland)     based in Skerries, IRELAND

ASP-CON: is a self cleaning, self-calibrating instrument that interfaces into your plant's control system. It provides continuous data on dissolved oxygen levels, bacterial activity based on respiration rates, suspended solids, sludge settlement, pH and  Ammonia concentrations, inhibitory conditions and the minimum DO concentration that your ...
