SLOT 2.0


The Challenge: 

Resilience | Increased Sludge Processing | New Processing Requirements 

AMP7 requires Water Companies to optimise their existing facilities, providing “resilience in the round”.  They also need to innovate, whilst providing great customer service and affordable bills.

The volume of sludge produced is increasing, with improved treatment solutions and the need to feed digesters creating greater amounts of green energy.  Legislative restrictions on
disposal will only become more onerous.

The nature of sludge is changing, with a drive to process ever thicker sludges to  increase throughput, along with the introduction of new processes resulting in novel sludge types that have rheological properties that
cannot be predicted using existing published rheology data.

Engineers are asking: 

How much energy is required to transport sludge within sludge treatment processes and beyond?

What are the best pump, valve and pipeline solutions to move the sludge efficiently and in a manner that is resilient? 

Are current sludge systems operating at an optimal level? 

Are pumps undersized and overworked?  Oversized and underworked? 

Is the pipework too big? 

What do I need to ensure my existing or new system minimises its TOTEX costs over it's lifecycle? What is the impact?  

How SLOT 2.0 helps

SLOT 2.0  enables engineers to produce an accurate asset design, reducing risk of asset failure and maximising TOTEX via an intuitive, easy to use online platform.

It also gives users the ability to predict sludge rheological properties based on type, dry solids and temperature with calculations derived from the
world’s largest collection of rheograms. They can also:

quickly compare results for different fluid rheological properties and combinations of pumps, pipework and components, plotting system curves against pump curves to determine the optimum pump selection and operating points

plot fluid flow curves and the hydraulic grade line against the system elevation profile to check the feasibility of the pump operating points.
