NAS - New Activated Sludge System

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

Anammox in active sludge: 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.

Biothane - Conventional Activated Sludge System

by Biothane - Veolia Water Solutions & Technologies     Office in NETHERLANDS

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 ...

Aqua - Activated Sludge-Water Separation System

by Aqua Industrial Watertreatment B.V.     based in Lichtenvoorde, NETHERLANDS

For the final step in the biological treatment of wastewater, the separation of bacteria from the purified water, AQUA Industrial Watertreatment disposes of three different systems.

Sludge Centrifuge

by Morselt Borne Ltd     based in Borne, NETHERLANDS

Morselt decanters can handle about 20 % more material when compared with conventional decanters having similar dimensions. In many cases, this feature brings out an increase in the dehydration process.

StrathKelvin - Model ASP-Con - Activated Sludge Plant Controller

by Strathkelvin Instruments Ltd.     Distributor in NETHERLANDS

The treatment of domestic sewage and industrial wastewaters is a critical activity to ensure that the environment is protected from the consequences of contaminated waterways. One of the most effective and enduring methods of treating these wastewaters uses bacteria to consume the organic contaminants before discharging to our streams, rivers and ...

Anaerobic Granular Sludge - Active Biomass for Inocculation and Kick Start UASB

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

Active biomass for inocculation and kick start UASB. Anaerobic wastewater treatment is frequently applied in several industrial sectors. The granular sludge plays a vital role within this technology. In this way waste water containing levels of organics (COD) is purified effectively. Anaerobic biomass present in the reactor transforms the organic ...

Biocenosis - Sediment Activator

by Avecom     based in Wondelgem, NETHERLANDS

What? Combined sludge aeration and in-situ production and seeding of good aerobic bacteria.

LysoGest - Sludge Digestion Optimizations

by ELIQUO Water & Energy B.V.     based in Barneveld, NETHERLANDS

At conventional municipal sludge processing, primary and waste activated sludge’s (WAS) are often mixed followed by anaerobic digestion. The easy degradable primary sludge’s could be normally dewatered more efficiently compared with systems where mixed dewatering of primary and WAS is applied. WAS is normally more difficult to dewater ...

Sludge Dewatering Technology

by Cellulose Assisted Dewatering of Sludge (CADoS)     based in NETHERLANDS

Cellulose – which comes fom toilet paper – is sieved from the raw wastewater (influent) by means of a fine sieve. This reduces the load of solid matter in the subsequent biological wastewater treatment process, thus reducing the energy consumed for biological treatment.

HydroThane - Model WSP - Water Desulphurization Process System

by HydroThane STP BV     based in KC `s Hertogenbosch, NETHERLANDS

HydroThane WSP (Water deSulphurization Process) removes H2S from the biogas by utilizing the available activated sludge from the aerobic treatment stage. The activated sludge will wash the biogas in counter flow, absorbing the H2S from the gas phase (H2S-rich) into the water phase.

Membrane Bio Reactors (MBR)

by AWT Watertreatment BV     based in Andelst, NETHERLANDS

Membrane bioreactors (MBR) combine activated sludge treatment with a membrane liquid-solid separation process. The membrane component uses low pressure microfiltration or ultra filtration membranes and eliminates the need for clarification and tertiary filtration. The membranes are typically immersed in the aeration tank; however, some ...

Model AD - Floating Weir Permanently Open Pump Discharge System

by Aquaturbo Systems, Inc.     Office in NORTORF, NETHERLANDS

Discharges subsurface laminar layer of clean water without disturbing the sludge blanket or floatables. Gravity and pump options are available with mechanical actuation to close the weir during aeration and mixing phases preventing wastewater or activated sludge entering the discharge pipe.

Model AD GRAVITY - Floating Weir Decanter Systems

by Aquaturbo Systems, Inc.     Office in NORTORF, NETHERLANDS

Discharges subsurface laminar layer of clean water without disturbing the sludge blanket or floatables. Gravity and pump options are available with mechanical actuation to close the weir during aeration and mixing phases preventing wastewater or activated sludge entering the discharge pipe.

Continuous-Batch-Reactor (CBR) Packaged Wastewater Treatment

by AWT Technologies Inc. - BIOWORKS group of companies     Office in NETHERLANDS

CBR uses sequential batch reactor activated sludge technology in a single modular process unit designed specifically for small facilities, to produce high quality effluent without the need for any complex controls or sophisticated moving equipment such as clarifiers, sludge scrapers and RAS pumps.

Aerator Performance Testing

by Air Products     Office in Utrecht, NETHERLANDS

The performance of aeration equipment is critical to the successful operation of an activated sludge process. Often, in building a new plant, the performance of such equipment must be tested against the manufacturers specification in terms of power used for the quantity of oxygen transferred to the water.

Model CBR - Packaged Wastewater Treatment Plant

by AWT Technologies Inc. - BIOWORKS group of companies     Office in NETHERLANDS

CBR is a process that combines the benefits of batch reactors and the more conventional activated sludge technology to produce a high quality treated effluent. This process offers reliability and simplicity of design in a single modular process unit, suitable for small communities up to 2,000 people.

Model type FBR - Biological Treatment Systems

by K-Pack Water Treatment B.V.     based in Amersfoort, NETHERLANDS

The K-Pack FBR is a compact built continuous biological wastewater treatment system. After pre-treatment (screening), the wastewater flows into a reactor tank with aerator. The reactor tank is filled with a mix of active sludge and water. Active sludge consists of biomass (bacteria flocks) that converts pollutants in the presence of oxygen. The ...

Biobulk - Model CSTR Series - Completely Stirred Tank Reactor

by Biothane - Veolia Water Solutions & Technologies     Office in NETHERLANDS

The Biobulk CSTR technology (Completely Stirred Tank Reactor) is a robust and proven process which treats industrial effluents with significantly high amounts of suspended solids. It is the anaerobic equivalent to the conventional activated sludge digestion system.

HYDRAsub - Model MBR - Hollow Fiber Membranes for Membrane Bioreactor

by Hydranautics A Nitto Denko Company     Office in BL Maastricht, NETHERLANDS

Hollow Fiber Membranes for Membrane Bioreactor Applications in Wastewater Treatment. HYDRAsub is used for MBR applications to treat any effluent (sewage or industrial source) with a significant biological activity.
