Full description

DCLM are seeking practical, feasible, and economically viable ways to solidify the concentrated leachate from the effluent treatment plant, comprising approx. 8750m3 per annum. These solutions should aim to solidify the concentrate utilising innovative solidification agents (alternatives to the current agents: ash and lime) in an environmentally friendly way. The goal is to effectively block any toxins from causing ground contamination.

Functional Requirements 

  • Deal with 40m3 of concentrate per working day.
  • Be applicable on DCLM landfill site
  • Be able to be integrated with DCLM’s current effluent treatment plant
  • Be practical for the South African environment
  • Solution must be applicable in modular format, so it may be scaled progressively
  • Please detail any new infrastructure requirements for this solution

Technical Requirements 

  • Solutions must be able to solidify the concentrate in 1 to 2 days (high priority)
  • Solution must be able to deal with hazardous materials
  • Solution must be sustainable with the intent to reduce carbon emissions. 
  • Solution to be non exothermic. 
  • Byproducts from alternative industries are desirable
  • Solutions involving valorisation for industrial use are desirable
