Leachate and Wastewater

Control and management of wastewater

 

Leachate management and control is one of the principal activities of landfill management. Many of the techniques employed to manage this type of contaminated water are also key aspects of the control of urban waste management. The Organics Group has been providing solutions for wastewater from many different sources for many years.

Leachate and Wastewater

Leachate, biogas, and wastewater are usually generated from similar sources: the decomposition of organic matter, either within landfill sites or municipal wastewater treatment plants. Careful assessment of the salient parameters is required to ensure the application of the most appropriate treatment solution.

Wastewater and Treatment

The accepted (and, it has to be admitted, very good) universal oracle, Wikipedia, defines wastewater as “used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff/ stormwater, and any sewer inflow or sewer infiltration.

Wastewater is cited as being a synonym for sewage produced by a community of people and collected via sewers.

It further defines wastewater as being contaminated water from:

  • Industrial processes including manufacturing, mineral extraction, power generation,
  • Wastewater treatment plants,
  • Landfill leachate,
  • Agricultural runoff including animal management,
  • Stormwaters, meltwaters, and excess rainwater.

Assessing the requirement

 

Defining the nature of a wastewater conundrum necessarily involves investigation to define extent, and it is obligatory to know the quantity and quality of the wastewater to be treated.

So, in any wastewater or leachate assessment study, the following must be investigated:

 

1. the anticipated flow rate which will require treatment;

2. the composition of the leachate or wastewater at source;

3. the permitted discharge consent by the regulating authority.

 

From this information, the technology needed to meet the discharge consent can be selected. As there are approximately twenty principal technologies that can be employed for leachate and wastewater treatment, it is clear that the more information that can be obtained prior to project design, the better.

Technologies may be combined in various modes with other standard chemical engineering unit processes, and this can provide a huge range of viable options from which a solution must be engineered to optimise the balance between cost and quality.

Leachate and Wastewater

Leachate and wastewater treatment remains one of the principal activities of landfill or municipal wastewater management.

Treatment Solutions

The range of technologies varies according to the method of treatment required for different types of contaminated water.

Track Record

Management of leachate and wastewater projects must be carefully planned to ensure timely delivery within budget. Here we showcase some examples.
