Water Research in India - Developing Water Quality Survey Tool

Selda Edris, BMI Fellow
Academic Advisor: Prof. Hadas Mamane

A single community may have a broad range of drinking water sources, each with different qualities, time-dependent accessibilities, economic models and price points. This complexity is further compounded by communities’ range of knowledge, attitudes and practices with the water they do collect, all of which have direct effects on the quality of the water they drink, and their likelihood to contract water borne disease in the short and long term. The goal of this research is to develop a simple tool for understanding drinking water quality in rural areas, by creating a water quality survey (WQS) which will ask the participants to predict the technical quality of their water. Correlation will be investigated between their predictions and their actual water quality - chemical, physical and biological analysis

Removal of Micro-Pollutants from Hospital Wastewater

Hospital wastewater are one of the point sources of various micro-organic persistent and toxic contaminants, secreted by the hospitalized patients. Treated wastewater (effluent) become an alternative water resource under the global water scarcity problem. In Israel, about 85% of the effluent water are allocated for agricultural irrigation and the rest goes into the sea or rivers and even for insertion into aquifers. Pharmaceutical residues are part of a group of persistent and toxic micro-organic contaminants that flows into the water-treatment plants from hospitals, industry, agriculture and domestic sector. These contaminants are resistant to conventional biological treatment used as a secondary treatment. As a result, those contaminants can still be found in the effluent that runs into rivers, and used in agriculture. In this study, we treat the pharmaceutical residues in the source, In that way, we decrease their concentration in the effluent and by that contribute to food security and environmental sustainability.

Microalgae Utilization for Removal of Organic Compounds from Wastewater: Circular Economy Concept

Patricia Akao, BMI Fellow
Academic Advisors: Prof. Dror Avisar and Prof. Hadas Mamane

Preliminary experiments utilizing microalgae Chlorella sp. to remove iodinated contrast media (ICM) showed great potential and as a result new experiments were performed over the course of 27 days, in triplicates. The positive and negative controls were performed in duplicates for each specific concentration (2, 5, 10 and 100 mg/L Iohexol - IHX).

The experiment showed that the microalgae may release an enzyme capable of oxidizing the IHX molecule. Ongoing research aims to better understand the oxidation pathway and characterize all nine DPs chosen. Further experiments are planned for next year.

The Boris Mints Institute Water Lab deals with the contemporary global challenges of water shortage and water quality through rigorous and groundbreaking research.
