JORDAN RIVER BACKGROUND WATER SAMPLE TREATMENT CURRENT TREATMENT IN Two Major Issues: Principal Sources ● Highly politicized - Religion and Regional Projects Hasbani River - ○ National Water Carrier Blank 20 µl 100 µl 200 µl 1000 µl ○ Headwater Diversion 3.69 NTU 1.27 NTU 0.50 NTU 5.25 NTU 6.35 NTU Plan Baniyas River - ○ Jordan Valley Unified Water Plan River - ● Heavily Polluted - Turbidity, Waste and Salt 20 µl 100 µl 200 µl 500µl 1000 µl Currently, the main treatment efforts go toward rehabilitation and 0.43 NTU 0.13 NTU 3.65 NTU 4.91 NTU 4.53 NTU “recharging the river” ● Prevention of raw sewage flow Physical Characteristics Coagulation ● Provision of desalinated brackish water and treated wastewater for ● Using PAC & Ferric Chloric Acid with a 17.5 & 35 weight ● Lowest elevation of any river in the world regional agriculture percentage. ○ Wastewater effluent ● More than 223 miles in length, actual distance between ● Stirred for 15 seconds at 120 RPM ■ At first, only purifying sewage at a primary (coagulation, source and the Dead Sea is 124 miles Flocculation flocculation, settling, etc. ) and secondary level (biological -- ● Shallow but the current is swift and carries silt ● Stirred for 15 minutes at 15 RPM activated sludge) Settling ■ Operating at a tertiary level in January 2016 (additional ● Thermal springs near Sea of Galilee give water a high ● Settled at zero RPM for 15 minutes degree of salinity clarifying processes) Turbidity ○ Brackish water ● Found that PAC at 100 µl was the most effective treatment ■ Desalination (reverse osmosis) concentration to acquire a turbidity reading of 0.13 NTU WATER ANALYSIS Coliforms COLORADO RIVER TREATMENT ● No coliforms were found in our water sample Parameters and Procedure: Potential Uses ● pH → pH meter TRIP TO ISRAEL ● Total Suspended Solids → mass reading and turbidity This water source is already ● Total Dissolved Solids → mass reading (gravimetric analysis) Few places represent the depth of ancient history and breadth of crucial to California & its and conductivity modern discovery quite like Israel.

Proposed Treatment Train Every state has its own treatment train depending on where the river is located and the contaminants affecting that area. The most common treatment train is as follows: 1. Screening 2. Coagulation & Flocculation 3. Gravity Filtration through multiple mediums REFERENCES ACKNOWLEDGMENTS a.
