The treatment unit of water or other products was designed to achieve in the most appropriate manner the characteristics of the desired quality for the product. Its specifications, as well as the level of automation, vary according to the customer's requirements and needs; solutions ranging from the simplest to the most complex, fully automated systems, can be delivered . Depending on each case, the installation may consist of charcoal filters, multimedia filters, manual or automatic valve pianos, interconnecting hoses and fittings, dosing pumps, PH readers, chlorine metering systems, water softeners, osmosis systems, etc. Tecnobento gathers a group of technicians who, at the beginning of a new project, perform the dimensioning in correlation with the customer needs in order to find an optimum balance between investment and returns. Coagulation and Flocculation During these steps, the impurities in the water are grouped by the action of the coagulant into larger particles (flakes) that can be removed by the process of decantation. The reagents used are called coagulants. Coagulation is the process by which impurities in the water are grouped. Flocculation refers to the process by which flakes are produced. Settling Settling is the process of separating solid particles from water by gravity, when the flow rate of the fluid is void or reduced, leading to sedimentation of these particles. Thus there is effective separation of flakes in the settling tanks. Filtration The settled water is routed to the filter units where the filtration process is performed. A filter consists of a granular porous medium, normally sand, of one or more layers, installed upon a drainage system, capable of retaining and removing the impurities still present in the water. Disinfection Disinfection is the destruction of pathogenic organisms capable of causing disease or other undesirable organisms. In order to perform the disinfection of the supply water, a physical or chemical agent (disinfectant) is used, namely chlorine. For this reason, the term for disinfection is commonly replaced by chlorination. Beyond Chlorine, there is the possibility of using other disinfecting agents, listed in order of frequency: Ozone, ultra-violet light and silver ions. The final chlorination aims to ensure complete disinfection and biological quality of the water being distributed. Occurs after the filtering processes. pH Correction The pH Correction is performed by adding chemicals so that the water does not become overly acidic. The acidity may cause corrosion of pipes and equipment. However, excessively alkaline currents can cause limescale.
