This process enables unacceptably wet or cohesive materials to be treated and used for construction purposes. Different treatments are available to suit virtually every soil type and can produce a range of different strengths according to use. Visit the Britpave website for more information click here. Effluent Treatment Many industrial processes utilise acids or acidic species which has to be treated before it can be discharged.The common method is to treat the effluent on site in a treatment plant where lime plays a crucial part in the neutralisation of the acidic species. Lime has the additional benefit of removing the toxic heavy metals present as an insoluble salt which is removed by filtration. Lime is relatively safe to use and handle compared to other alkalis. Being a natural product, the product costs are low and does not suffer the large fluctuations of selling prices as with other alkalis. Download a pdf file "Lime for a Clean Environment". Biosolids Biosolids treatment by Lime Stabilisation can be achieved by applying a controlled dose of hydrated lime or quicklime to sewage sludge. This is considered the best method of treatment to produce a valuable end product, both simply and efficiently. Pressure is mounting from the public, supermarkets and from agricultural buyers to stop the practice of injecting or spreading untreated sewage sludge on land or at sea. Guidelines agreed between ADAS, Water UK and the Retail Consortium the "ADAS Safe Sludge Matrix" bans the use of untreated sewage sludge from 31st December 1999." Under these guidelines, advanced treatment of sludge will be required for most agricultural applications.

Many such fuels contain sulphur and the resultant emissions into the atmosphere are the principal cause of acid rain. Other sources of acid rain can be incinerators whether they burn municipal or industrial waste, clinical waste, animal carcasses or natural fuels. Almost all incinerators around the world have utilised lime as a means of removing harmful gases for many years and proved lime to be cost effective, efficient and sustainable.

In addition Lime makes mortars more pliable and less prone to water penetration. More information is available in the pdf file below.
