CRITICAL DESIGN PARAMETERS FOR CONSTRUCTED WETLANDS NATURAL WASTEWATER TREATMENT SYSTEMS
Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 12
Abstract
Constructed wetlands, also known as natural treatment systems, are designed for wastewater treatment especially in rural sections. They are used primarily for domestic wastewater treatments of small communities. Influent wastewater is treated in specially design basins containing graded substrate material and planted with aquatic plants. Since there are several physical, chemical and microbiological processes happening in these basins, a special attention should be paid for design parameters of these systems. Improper design and operation may result in serious failures and malfunction of the system. Instead of simple or general design parameters, site-specific parameters considering local climate, site topography, influent wastewater characteristics and locally available materials should be taken into consideration both to have optimum operation and to minimize the system costs. Proper operation, maintenance and monitoring processes should also be performed in these systems since the success of the system is not totally depend on design parameters. In this study, critical design parameters of constructed wetlands were assessed and potential mistakes made in design of constructed wetland systems of Kayseri province of Turkey were provided and solutions were proposed for already existing problems.
