Engineering & Design Sewage Plant
The engineering of a sewage plant involves various factors to take into account and one of them is the characterization of the water. Having defined the water conditions is essential to lay the foundations of the design.
Engineering project for industrial sewage plant
Biofil has an expert team of engineers with whom it develops customized projects for sewage treatment plants with the necessary technology to optimize natural resources.
The mission is to try to eliminate the contaminants present in wastewater
In the case of industrial projects, pilot trials are generally required, in addition to the design, construction, operation and maintenance of facilities intended to treat or regenerate wastewater before it is returned to the environment, to a municipal facility or to storage for its reuse.
The engineering process for a wastewater treatment plant will be different if the water to be treated is solely of domestic origin, if it is totally industrial, or if it is partially composed of both.
If the origin is completely domestic, only knowing the daily flow and the final destination of the treated water is enough. If the water is industrial or partially industrial, analysis of the residual water is carried out to determine its composition and the contaminants present. This makes it possible to define the appropriate treatment processes and technologies.
Design of the characterization system
This can normally include integrated sample collection equipment, pipes, pumps and pumping stations and transport the samples from their source to the laboratory. In industrial waters, a pilot plant installed in a laboratory or on site may be necessary.
An analysis of the residual water is carried out to determine its composition and the contaminants present. This makes it possible to define the appropriate treatment processes and technologies.
In this phase, in municipal waters, the sedimentation of the solids suspended in the wastewater is carried out. In the case of industrial waters, the most common is to design a homogenization, which may or may not be aerated. In the first case, settlers or settling tanks are used where the densest suspended solids settle at the bottom, forming the primary sludge, while the clarified water is collected at the top.
In the case of municipal water, it will be a biological reactor that, depending on the intended objective, may have different characteristics. In this stage, the organic contaminants present in the wastewater are broken down and transformed. The most used biological systems are the trickling filter, a moving bed system (MBBR), a membrane bioreactor (MBR), a hybrid system (moving bed), where microorganisms decompose organic matter into CO2 + Water + other compounds.
In some cases, it is necessary to apply an additional treatment to remove nutrients that can be harmful to the receiving media, such as filtration, chemical precipitation or advanced technologies such as ultrafiltration membrane.
Disinfection and biological treatment
Chlorination, ozonation or ultraviolet irradiation techniques can be used if deemed necessary for reuse.
During the treatment process, sludge of different characteristics and quantities is generated, depending on the process from which it comes. This sludge must be managed properly, it must be dehydrated to reduce its volume as much as possible, and also depending on its origin, it can be used as a fertilizer in sanitary landfills, construction, etc.
Installations in sewage plants with Biofil resources
From Bio-fil we emphasize that the design and specific processes may vary depending on the characteristics of the wastewater to be treated, local environmental regulations and other factors. The engineering of a wastewater treatment plant requires a multidisciplinary approach that includes civil, environmental, chemical and control engineering, among other branches, to guarantee effective treatment and comply with the water quality standards established in each place.
