Optimal Treatment of Domestic Wastewater through Constructed Wetlands

Method

Water quality analysis was carried out to assess physico-chemical and biological properties of water at various stages of the treatment and its suitability for domestic and irrigation purposes. Water samples were collected from nine locations (marked in Fig. 2) twice at 45 days interval. The water samples were collected in clean acid washed one liter polythene bottles. Temperature, TDS, Conductivity and pH were measured at the site. Water quality parameters were analyzed as per the standard protocol (APHA 2017). Algal samples collected from sampling locations were identified using standard keys (Prescott 1978, 1982) based on their external appearance, colour, morphological characteristics, size, habitat, structure and orientation of chloroplast, cellular structure and pigments etc. Water samples collected were concentrated by centrifuging to 15 ml volume.
