Abstract
The aim of this study is technical and statistical evaluation of wastewater treatment plants existing at the holiday resorts in areas surrounding Izmir City. The study was carried out in the time period from August to September 2018. Within the scope of the study, 150 holiday resorts were investigated and listed. The necessary permissions were obtained and the treatment plants were visited at their current locations. Most of the wastewater treatment plants are embedded in the ground and are referred to as package treatment systems. They are used at holiday resorts for many reasons, such as smell and noise control. Many parameters have been considered within the scope of the study, such as installed power of the plant, influent wastewater flow and pollutant concentration, the properties of the sludge, sludge disposal methods, effluent wastewater parameters, the method and location of effluent water discharge, operation period of the wastewater treatment plant. As a result of this study, it has been found that the low cost package treatment systems were generally preferred. The systems that required most energy were the blowers. In order to provide clean and smooth environment, the use of central wastewater treatment plants is more suitable than the use of package treatment systems
Highlights
The water pollution problem is an important and increasing issue
Wastewater is measured with parameters such as biological oxygen demand (BOD), chemical oxygen demand (COD), ammonium, orthophosphate, nitrate etc
As a result of the 150 facilities investigated, 50.66 % were in Küçük Menderes Basin, 1.33 % were in Gediz, 1.33 % in Büyük Menderes Basin and 24 % in North Aegean Basin
Summary
The water pollution problem is an important and increasing issue. That is why the rise of the environmental consciousness becomes more significant in national and international levels.The existing water treatment and distribution systems are of great importance because of the water quality standards [1]. The water pollution problem is an important and increasing issue. That is why the rise of the environmental consciousness becomes more significant in national and international levels. The existing water treatment and distribution systems are of great importance because of the water quality standards [1]. There are many different wastewater treatment processes, such as mechanical, biological, physical and chemical, which are usually used separately or together depending on discharge standards into receiving media or reclamation and reuse purposes. Wastewater is measured with parameters such as biological oxygen demand (BOD), chemical oxygen demand (COD), ammonium, orthophosphate, nitrate etc. These parameters provide significant impact on the quality of the influent, effluent wastewater [2]
