What quality of water is produced?
With sewage treatment, water quality is defined by the level of three forms of pollutants that are present in the water exiting a treatment plant. The three pollutants are • BOD – Biological Oxygen Demand (a measure of the biological pollutant load) • SS – Suspended Soils (small particles of waste matter) • Ammonia – (Ammonia is the chemical that creates urine odour) The better a treatment plant’s performance, the lower level of these pollutants, expressed in milligrams per litre – Owls Hall will only specify treatment plants meeting the strict regulatory guidelines. It is important to bear in mind that discharged water from any plant is not suitable for consumption or washing but a sample will have a high level of visual clarity.
