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

by Environmental Treatment Systems, Inc.     based in Acworth, GEORGIA (US) (USA)

The activated sludge process is a biological wastewater treatment process that uses microorganisms, including bacteria, fungi, and protozoa, to speed up decomposition of organic matter. Activated sludge is an aerobic process requiring oxygen for treatment. As the microorganisms grow and reproduce, waste materials are removed.

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 ...

NAS - New Activated Sludge System

by Colsen International b.v.     based in HULST, NETHERLANDS

Application: NAS (New Activated Sludge) represents a unique active sludge system in which anammox bacteria constitute a part of the biomass. These micro-organisms ensure a very effective removal of the nitrogen during aerobic purification. An aerobic purification step is often necessary to enable the removal of the remaining COD fraction and ...

User friendly software providing a real time display of bacterial respiration. Automatic Report generation and calculation of EC10,20,50 values for carbonaceous and ...

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 ...
