Domestic Wastewater Treatment

Domestic Wastewater is commonly wastewater originating from residential areas and mostly from service sectors such as schools, hospitals and hotels where domestic activities and daily life activities of people take place. Domestic wastewater is treated with biological treatment processes.

Domestic wastewater treatment facilities are classified according to the number of people they serve. Mechanical, biological and chemical processes are used in wastewater treatment. In mechanical-physical processes, which are generally determined as the first step, undissolved suspended solids are removed from the wastewater. These particles are separated using pre-treatment steps such as screening, filtration, pre-sedimentation or dissolved air flotation depending on the density. Light materials such as oil and grease float, high-density materials settle to the bottom. Components such as screening, sieve, oil trap, sand trap, flotation and pre-sedimentation are used for mechanical cleaning.

With Biological Treatment; Organic substances in wastewater are converted into carbon dioxide, water and new microorganism cells with the help of microorganisms. Biological treatment systems can be classified in different ways.

Wastewater treatment plants require strict control of sludge management, chemical management, energy saving and operating costs. In recent years, this situation has been facilitated by the introduction of advanced technological solutions such as real-time control centers in treatment plants.

In this context, we offer suspended and fixed film (biofilm) processes by comparing the status of the microorganisms used in these systems, which are classified as air (aerobic) and airless (anaerobic) according to the presence of oxygen in the environment. These processes are treatment methods such as Activated Sludge System and Modifications, Biofilm Processes, Stabilization Pools and Advanced Biological Treatment Processes.
