  • Solidification / Immobilisation of sludge from physical-chemical WWT process

    In 2003 econ received an inquiry from a service company operating an industrial waste water treatment plant. At the end of the physical-chemical WWT process this client generated metal-hydroxide sludge from his chamber filter presses. Originally he discharged the sludge into skips and brought it to a hazardous waste landfill. At this landfill, a solidification process was used to stabilise ...

  • Algae Problems

    Almost everywhere where water is being stored, algae problems may occur. When water is stagnant, has a high temperature or a high concentration of Nitrates and Phosphates, an algae bloom might occur, which can cause several problems. Blue-green algae growth can cause a foul odour to the water, a layer of scum on the surface and even pose a health risk. Green algae may colour the water green, look ...

  • Impacts of Climate Change on the Occurrence of Harmful Algal Blooms

    Climate change has been occurring naturally as well as caused by anthropogenic activities over the decades. In relation to the fresh and marine water, the concentration of greenhouse gases results in temperature rise of surface water, lower pH and changes to precipitation, evaporation and vertical mixing of water. All these consequences of changing the environment in combination with excessive ...

  • The Use Of UV For Dechlorination

    For many years chemical disinfection techniques have been used to provide microbiologically pure water for industrial and domestic use. Free chlorine, typically introduced by municipal water treatment plants in gaseous form, has been employed for many decades as a primary oxidising agent for the control of microbiological growth. Free chlorine can also be introduced through the injection of ...

  • Generation using gas-fuelled engines in South Africa – an overview

    Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, ...
