In big industry, such as the chemical and manufacturing industries, the same simple methods can be used to reduce water usage.
Produce a Water Efficiency Action Plan that outlines your initial findings, sets out problem areas, priority improvements, targets and timescales. Communicate the plan and potential benefits to everyone concerned and get feedback.
When creating your Water Efficiency Action Plan you should consider all the opportunities to reduce water use in your manufacturing centre including:
Opportunities for businesses to reduce water usage usually occur when new processes are being designed or existing vessels are being refurbished. However, by being aware of general good practice, you can take advantage of other opportunities when they arise.
When the opportunity to purchase or redesign new vessels and containers does arise, basic design aspects that you should look for include:
There are also several ways in which your manufacturing centre can reduce and optimise the use of water in cooling systems:
You can also reduce water use in liquid-ring vacuum pumps by:
Although mains water is often required for many manufacturing processes, you can reuse water or use lower quality water for some applications such as cleaning, toilet flushing and wet air pollution control.
Cooling waters and some effluents, (treated and, in some cases, untreated), can frequently be reused for other purposes around your manufacturing business, such as toilet flushing and cleaning. Simple treatment methods, such as settlement and filtration, increase opportunities for reuse. With careful planning, it’s sometimes possible to reuse effluent more than once.
By monitoring and evaluating business water use, and employing equipment that facilitates water efficiency, your manufacturing centre can quite easily make impactful savings on its water usage.
Over time, these efficiencies can result in significant cash savings that can free up budget for better use in other parts of your business.
