  • Energy from waste: the recycling of limed fleshings

    Leather products have been around a long while - there are those who claim that it is the second oldest business in the world. Going back a few millennia, when our earliest ancestors decided that sitting on hard rock was not a soft option, they turned to other materials in order to create more comfortable seating, as well as warmer bedding and improved clothing. Animal skins became the fabric ...

  • Sioux Falls, Verder Pumps

    The Sioux Falls Water Purification Plant in South Dakota USA, had always relied on gravity to feed slaked lime slurry to their softening basins. In 2009, the staff decided to give gravity a helping hand by trialing a pump to move the slurry more effectively. Lime slurry is a dense product to transfer with a high solid content of up to 35%. Due to the slurry’s abrasive nature which causes ...

  • Peristaltic pumps for moving filtration water

    The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents and is one of three plants operated by the city of Osnabrück in northern Germany. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant's capabilities. To deal with this situation, engineer Peter Sikora organized a team ...

  • Peristaltic Pumps play key role in rectifying the pH balance of mine water

    After decades of uncontrolled industrial (mining) activities, water supply is under serious threat. Studies show that acid water levels in the country's mines are rising at a staggering average rate of 0.59 m/day. The water situation is in fact threatening the population’s survival. At the heart of resolving this problem are the treatment of water and wastewater. This article looks at ...

  • Calcium Carbonate, a solution to the energy crisis!

    A 'chemical' solution exists to solve jointly the energy crisis and CO2 release. Thanks to the Lime, “Cycle C4” could produce liquid fuels (petrol, diesel, etc.) with no CO2 release. The cycle presents no technological uncertainty, each step is widely known and controlled. Profitable with a barrel quote at 100 dollars. In 2004, the International Energy Agency annual report predicted that oil ...

  • A Plast-O-Matic degassing valve eases the filtration process of sodium hypochlorite bleach

    The manufacturing of bleach has come a long way since the early years of the First Industrial Revolution. Back in 1799, Scottish chemist Charles Tennant patented a lime powder that was manufactured by treating lime with water, spread thinly over the concrete floor. Chlorine gas was then pumped into the room and absorbed by the lime. This development of bleaching powder as a source of chlorine by ...

  • Optimising the Rehabilitation of polluted Mine Tailings and Water by SupaZorb

    To date the polluted acid mine drainage (AMD) – the second biggest environmental problem of the world - from South Africa’s gold mines, was characterised and treated by the precipitation of heavy metals with lime and sulphates, by means of iron exchange. The chemical treatment with expensive and toxic caustic soda (Sodium Hydroxide, NaOH) is to lift the pH, in order to reduce the corrosion on ...
