Nutrients control is still a problem even after the adoption of best practices and the use of best technologies. Thus, a finer and better method is to be devised in order to remove nutrients from water bodies before the water is released for its reuse. STEPS has come with the following method: effluent water is normally collected and is flowed through fixed paths into the treatment plants or into the water bodies for final disposal. The pathways are normally, sewage channels, open drainage systems, etc. In large cities, pipelines carry the sewage. In industries, pipelines carry the effluents. So, the path way for the water is well defined and well known. STEPS system envisages the interruption of these pathways at selective locations, and allows the water to pass through a nutrients absorbing fixed bed. In case of open drainage systems, a part of the drainage can become a location for the containment of nutrients. STEPS EX-CLAY system consists of a natural clay processed at high temperatures. The specific type of clay, when processed at high temperatures, develops a molecular structure with a high pore volume and a non-dissolvable physical structure. The high pore volume allows the nutrients to be bonded to the clay matrix rapidly, so that water will be nutrients free thanks to the porous structure. The EX-CLAY system is similar to PHOSTRAP in the sense that both are clays. The EX-CLAY system acts as a receptacle to hold nitrogen fixing bacteria, and at the same time, it locks the phosphorous to its clay matrix. EX-CLAY is in the form of large globlets or small granules. The granules are then used a filtration media.
