Abstract This study aims at assessing the validity of sewage water primary treatment in the production of oil crops. These oils can be converted to biodiesel. Also assessing the quality of oil, according to the European standards and American and German ....... etc. Here it is possible to find added value of the use of sewage and provide irrigation water in the production of food crops. This experiment was conducted in the province of Kafr El Dawar Beheira Center on an area of 1 fed, divided to four sections each of 1/4 fed. to cultivate safflower and Rapeseed. 1/4 fed Safflower irrigated with sewage water treatment initial 100% (0% irrigation water) and 1 / 4 fed Safflower irrigated with irrigation water to 100% (0% sewage) likewise in rapeseed. Both of the soil and irrigation water and treated sewage water were analyzed. The results were as follows: Treated wastewater preliminary conform with the standards of use wastewater in agriculture to FAO, but there were differences chemical small amounts such as ammonia 5.75 mg /l in wastewater treatment while limit in standards is 5 milligrams per liter. Ratios of nitrogen, phosphorous and potassium in treated sewage water higher than the quantity in the traditional irrigation water. All measurements morphological features were decreased with the use of treated sewage water only shoot length was increased. Increased density and viscosity of the oil of plants irrigated with treated sewage compared to those irrigated with irrigation water. from the results of the Gc increased oil content of unsaturated fatty acid in oils of plants irrigated with treated sewage preliminary report on those plants irrigated with traditional irrigation has increased unsaturated fatty acids from 66.04% in safflower irrigated conventional irrigation to 83.36% in the irrigated safflower wastewater processor prototype. Another change in oil properties was iodine number, it is increased from 121.55 in rapeseed irrigated with irrigation water to 142.2 in the primary sewage water treatment also accrue in safflower from 120.46 to 135.35. As conclusion the obtained biodiesel from the oil extracted from both rapeseed and safflower conform with the international standards except in the value of cetane namber which can be modified by one of the following: 1. Transesterification with propanol, 2. Blending with propanol. |
