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
