Abstract

Constructed wetland was applied for initiating domestic wastewater treatment process. Variation of plant density and Hydraulic Retention Time (HRT) were observed. Domestic treatment performance was improved by increasing plant density and HRT but only HRT of 4 days could be achieved. Thailand’s effluent discharge standard was studied. Vegetation or non-vegetation wetland could remove total suspended solid due to physical mechanisms (filtration, sedimentation and adsorption) while Chemical Oxygen Demand (COD) and ammonium were removed by plant and microorganisms which attached at root zone and wetland media. Using constructed wetland for thermal transfer reduction and sewage treatment purpose could be applied at plant density of 20 plants/m2 and HRT of 4 days. Moreover, increasing of plant density could reduce heat transfer to house because of rising relative humidity around wetland area and nearby atmosphere.
