WaterPinch implements Linnhoff March’s patented systematic technology for analysing water networks and reducing water costs for processes. It uses advanced algorithms to identify and optimise the best water re-use, recycling, re-generation and effluent treatment opportunities. The software implements what is potentially a very complex technology in an intuitive, user friendly manner, enabling engineers to analyse even the most complex problems at the touch of a button.

	Clear and easy data entry
	Targeting and design of optimised water networks
	Rapid scoping and screening of project alternatives
	Includes built-in models of standard equipment items
	Contaminant sensitivity analysis to identify critical water users
	Fully featured water network design facilities

An established track record

Our WaterPinch software has already been used extensively in water and effluent minimisation studies and has identified significant savings in a wide range of industrial applications.

Using the software yourself or in a project together with Linnhoff March engineers, you will be able to identify the critical areas of your water network and to find projects that will reduce freshwater and effluent treatment costs. It will even help you to establish a long-term expansion/operation strategy for your site.

How it works

By analysing complete or partial water systems, WaterPinch highlights those processes where money saving potential is greatest. The software then helps you to:

	Identify where water can be simply re-used or recycled and how this is best achieved
	Find the best intermediate treatment options that will allow water to be re-used or recycled
	Investigate the potential benefits of relaxing the current operating practices of the water-using processes
	Determine which streams to include in a distributed effluent treatment scheme to reduce overall wastewater treatment cost
	Rapidly evolve the network to find the best practical design changes and improvements

The algorithms for network evolution take into account such factors as water re-use, water recycling, partial and intermediate treatment, existing water treatment units, geographic location, piping and installation costs and preferred or forbidden connections.

The sensitivity graph quickly shows you which are the important contaminants and processes limiting your water saving potential. Relaxing the allowable inlet concentrations to the most sensitive processes will maximise your savings.

The best approach to water minimisation

WaterPinch is the best systematic approach available for minimising water usage and effluent treatment load. It can help whether your driving force is capital cost avoidance, operating cost reduction or minimising environmental impact.
