Abstract

The present disclosure consists in a set of processes in the treatment of wastewater which provides diverse benefits comprising an improved sedimentation using hydrated lime for a better clarification of water in the process, the process including a method to completely eliminate unpleasant odors with the addition of calcium nitrate, which also prevents corrosion by using a suspension of calcium hydroxide. A process for the removal of phosphors and phosphates, with the advantage of also removing suspended solids, organic matter, reducing content of coliform organisms and viruses as well as heavy metals. Ammonia desorption and a system for wastewater treatment that is processed by a set of concrete tanks with a slight slope allowing a constant flow, which are constructed or modified in the general drain collectors wherein aerobic bacteria and oxygen are added to such tanks, depending on the type of water to be treated, said tanks generally functioning as primary and secondary systems a nd, in particular, as a tertiary system to deliver a specific type of water using gravity as a driving force of the modules wherein the physical and chemical processes take place, also using solar panels for a minimal power consumption, which are provided with electrical power and its consumption is equal to a dwelling unit in said 2 LPS process without the aid of electricity, resulting in a much more economical water treatment process in relation to water treatment plants with similar volumes.
