WATER & EFFLUENT TREATMENT Identifying hidden costs in your water usage For most industrial and process businesses, water is one of their key utilities, along with electricity, gas and perhaps compressed air. It is estimated that the manufacturing sector uses some 14% of all water consumed in the UK, for process, ingredient, steam generation, washdown and cleaning duties. As such, any rise in the cost of water supplies, whether taken directly from the mains or abstracted from boreholes or surface water sources, will have an impact on operating costs. There is increasing awareness across industry that companies using large volumes of raw water as an inherent part of the process can make significant savings in supply costs through water reuse or recovery. This water can provide a cost-effective supply for cleaning floors, machine washdown, boiler feed or similar duties. The question is how to apply such a solution in a way that is truly beneficial to the bottom line without demanding hidden costs. The truth is that the cost of water as a raw material is not high. You can put together a scheme to recover process water but in terms of capital costs this could be quite expensive, and the payback may be several years. To avoid the hidden costs of water usage, you need to look beyond the cost of the water itself and evaluate the processes used to treat it. A Solution, Reverse osmosis feeds water under pressure into a module containing one or more semi-permeable membranes. This process removes up to 98% of inorganic ions, plus virtually all colloids, micro- organisms, endotoxins and macromolecules. The effectiveness of these membranes helps reduce further the hidden costs associated with water reuse. For example, most engineers know that when evaluating a system for energy efficiency, pumps are typically energy- hungry components that demand far more of their lifetime cost in the form of energy consumption than anything else, so minimising pump speeds is always a great benefit to efficiency. Feed pressure can be significantly reduced by up to 50% using the latest reverse osmosis membrane. To ensure the most cost-effective results - and to avoid the hidden costs of water reuse - it is vital to establish a relationship with an expert supplier that is consistently active and focussed on the specification, design and manufacture of water purification technology. For over 40 years, SUEZ has been at the forefront of water purification technology, providing equipment, systems and long term support to our customers in markets ranging from food and drinks to laboratory and research, healthcare, electronics, manufacturing, chemical production and beyond.

In many cases an additional area of focus is recovering as much “good” product as possible by minimising the waste material flushed to effluent treatment, or waste disposal. Production line pipe cleaning in industrial manufacturing has historically been carried out by water flushing. This can be an inefficient method when the properties of the materials being cleaned prove difficult to CONTINUED ON PAGE 168 read online: SHOW GUIDE - AUGUST 2018 167
