How Water Companies Save Up to £17,000K P/M

Increasing demands on water companies to meet environmental targets, reduce costly overheads and streamline operations have opened up further debate on alternative ways to be more profitable.

The UK Government and the Environmental Agency produced an evidence document in 2009 “transforming wastewater treatment to reduce carbon emissions”. The WFD (Water Framework Directive) set targets that good chemical status needs to be achieved by 2015.

So in 2016, today’s innovative water companies are shifting their focus from sewage disposal to energy generation.

Generating gas from sludge at large water treatment sites using anaerobic digestion and thermal hydrolysis infrastructures is a key part of the solution.

In a recent article in “Water and Waste Treatment Magazine” I discuss an effective solution that reduces costly overheads, transport logistics and processing waste. The in-depth article titled “Getting to grips with… sludge cake optimisation” covers and answers important areas such as:

  • What issues do water companies face from building new advanced digestion facilities?
  • Why do water companies need to transfer sludge between sites?
  • What methods are available for transporting it?
  • Why is sludge dewatering important?
  • How important is the quality of your sludge to you?
  • Why is the choice of storage systems important?
  • Why change from a hook lift container storage system?
  • What factors should be borne in mind when designing the Reception facilities on site?
  • How can costs of the process be reduced?
  • What’s the “transport system” cost / benefit?

In an article titled Sludge Management Water UK said: The recycling or disposal of sludge in a sustainable manner is a major challenge to the water industry”.  In a further statement they have said: “Many water companies have decided to increase renewable energy generation to offset the impacts of increased energy prices, to use their resources (e.g. sludge) as efficiently as possible”

The solution of dewatering of slurry and processing into cake reduces load volume representing 4:1 reduction in volume and enables a quicker turnaround of trucks, reducing transport and storage costs. This means 1 truck could be used instead of 4, typically the saving is around £10,000 to £17000 per month for a 100m3 truck loading silo.
