Water Hackaton Tel Aviv 2011
Non- potable and recycled sewage water are widely available however it has variable or high levels of salinity
Provide a solution to minimize usage of potable water for crops irrigation
Salinity levels required for various crops
Type of crop Salinity level (PPM)
Sensitive crops- Pepper, Flowers, Eggplant, Various Fruits
<700
Semi-tolerant crops-Tomatoes,Olives, Grapes
700-1500
Very tolerant - Dates >1500
Alternate operation principle
50% ratio -1500*.5+300*.5 = 1150 PPM
30%/70% ratio – 1500*.3+300*.7= 660PPM

Salinity formula: s=(s1*T1+s2*T2)/(T1+T2)
Reducing the salinity hazard to sensitive agricultural crops
Appropriate technology for using saline water for arid zones ( Developing countries and others)
Appropriate technology for using recycled sewage water to agricultural and ornamental crops
