  • 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 ...

  • 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 ...

  • Technical Focus: Sludge Blanket

    Regardless of treatment process, sludge blanket control is an important aspect of any wastewater treatment plant, and correct monitoring and treatment of sludge is paramount for efficiency and cost control. Manual monitoring of sludge blanket levels is an occasional and often rushed method of control and can lead to inaccuracies being compounded over time, potentially leading to overspill into ...

  • Heat Pump Used to Drain Contaminated Sludge in a Steel Factory

    Summary In 1987, new regulations required that factories dispose of their contaminated water and waste themselves. Making galvanised steel wire, the Stelfil factory produces sludge contaminated with lead and zinc. Stelfil spent thousands of dollars to bury this waste and evaluated three systems to remove most of the water: a gas dryer, an induction heated screw conveyor and a heat pump system. ...


  • Bristol WWTW solves sludge problems with large auger pump

    Built on the coast, Wessex Water’s Bristol Waste Water Treatment Works (WWTW) is the UK’s sixth largest works serving a population equivalent of 800,000 from Bristol and surrounding areas. To help comply with the EU Urban Waste Water Treatment Directive, Wessex Water has a Biodrier system at Bristol to transform two thirds of the site’s sludge into dry, odourless fertiliser granules. The W Range ...

  • Geotube Dewatering for Lagoon Sludge - Case Study

    Background In many animal waste management schemes it is desirable to separate solids from waste water and/or manures. In cooperation with the Department of Animal and Dairy Science, animal waste specialists from Biological and Agricultural Engineering are field testing a technology new to agriculture, to remove solids from lagoons. The test is currently being conducted at the UGA Dairy ...

  • Transportation of digested sludges over extreme distances

    Sludge is a residual product of sewage treatment that, as a rule, is digested and concentrated. In larger processing plants, it is dehydrated, partially dried and subsequently utilised in other processes. This usually takes the form of incineration and subsequent use as an additive to building materials by the cement industry. In the sewage treatment plant (STP) of the local authorities ...
