  • Chopper Pumps: Pumping of septic sludge

    Landia chopper pumps have a great record of application in septic sludge. Septic sludge is raw unscreened sewage often delivered by tanker trucks from remote sites such as summer houses, camping sites, harbours, etc. Septic sludge contains many different solids tending to clog up pumps, everything people possibly can flush down a toilet! At this particular plant, a DG-I 4,0 kW –1500 kW was ...

Pulsar’s Pulsarguard 500 units are used by Whale Tankers to ensure that their specialist positive displacement pumps never run dry. By employing the Pulsarguard unit, staff are able to allow the pumps to operate unattended, confident that there ...

  • Chopper Pumps: Saeby fish processing plant, sludge tank mixing and pumping

    The sludge is coming from the dewatering unit, includes polymers, and has a dry matter content of 15 %. A Landia dry installed pump type MPTKR-I 18,5 kW pump was installed. The pump mixes the tank contents through a recirculation system and pumps the sludge to a tanker truck. The pump was built with a special feeder propeller to make sure it could handle the high dry matter content. The ...

  • New processes for the improvement of sludge digestion and sludge dewatering

    INTRODUCTIONThe examination of numerous sewage sludges from municipal wastewater treatment plants leads to the conclusion that on the one hand dewaterability of these sludges worsens and that on the other hand dewaterability of sludges becomes more and more important due to increasing disposal costs. Especially wastewater treatment plants with inflows from the food processing industry often face ...

  • Dewatering of Industrial Sludge - Case Study

    At Ten Cate Protect, town of Nijverdal, The Netherlands, 2006 During the wastewater treatment process at Ten Cate Protect large quantities of sewage sludge are liberated. A couple of days per week this sludge is transported in tanker trucks to a waste disposal plant. On June 14th 2005 a Geotube MDS unit was put in operation at Ten Cate Protect to separate and condense the sludge of the aerobic ...

  • Examination of sludge accumulation rates and sludge characteristics for a decentralized community wastewater treatment systems with individual primary clarifier tanks located in Wardsville (Ontario, Canada)

    In conventional septic systems, settling and partial treatment via anaerobic digestion occurs in the septic tank. One of the byproducts of solids separation in the septic tank is a semi-liquid material known as septage, which must be periodically pumped out. Septage includes the liquid portion within the tank, as well as the sludge that settles at the bottom of the tank and the scum that floats ...

  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

  • Operational cost optimization modeling for conventional activated sludge process

    Energy and solids processing cost accounts for 40% of the total operation and maintenance costs in wastewater treatment facilities. This indicates the potential for saving operation and maintenance costs through the process optimization. The limitations of most cost optimization studies carried out in the past are either these studies could not be applied to existing facilities as the objective ...

  • Common Treatment Technologies for Fuels in Soil, Sediment, and Sludge

    Common treatment technologies for fuels in soil, sediment, and sludge include biodegradation, incineration, SVE, and low temperature thermal desorption. Incineration is typically used when chlorinated SVOCs are also present with fuel, and not specified for fuel-only contaminated soil, sediment, or sludge. All types of biodegradation, both in situ or ex situ, can be used to remediate soils: ...

  • Case Study: Farm pond sludge and algae remediation

    Problem A 1 ½ acre farm pond located in southeastern Wisconsin was experiencing a severe algae bloom due to high levels of fertilizer runoff from the surrounding farm fields located on the north and east sides of the pond. Farm field runoff drains into the north end of the pond via a 4-inch drainpipe. The pond is further fertilized by the year round population of 6-8 resident ducks and by ...

  • Prediction of Strutive Formation Potential in EBPR Digested Sludges

    ABSTRACTLow operating costs and less sludge generation associated with EBPR (Enhanced Biological Phosphorus Removal) have led existing wastewater treatment plants to retrofit their phosphorus removal systems and have encouraged new plants to incorporate EBPR into their design. However, in plants that use anaerobic digestion, the introduction of EBPR may result in the formation of scales of the ...

  • Activated Sludge Treatment Plant - Eatonton, Georgia - Case Study

    Solids management at municipal wastewater treatment plants is crucial in maintaining operating efficiencies and permitted discharge levels. Drying beds and mechanical methods of dewatering bio-solids can be labor intensive and inefficient for rapid solids removal. Miratech Geotube" Dewatering Technology offers munic-ipalities a cost effective solution for rapid solids removal and long term solids ...

  • Canada pump and power utilizes hydraulic submersible pumps in unique applications

    Abrasive slurry, temperature swings of more than 100 degrees Fahrenheit, remote locations…any of these things would test a pump system.
