UTILIZATION OF SEWAGE WATER IN THE PRODUCTION OF INDUSTRIAL OIL ANF FIBERS FROM SOME PLANTS

Abstract

The current work aims at gaining more information about, the suitability of primary treated sewage water alone or mixed with different rates of Nile water in product multi function plats such as flax (Linum usitatissium L.) class variety Sakha2 and kenaf (Hibiscus cannabinus L.) class variety Giza 3 for use their oils products and it fibbers. The use of primary treated sewage water in this study achieve high environmental values, achieve the economic returns of provision traditional irrigation water to irrigate food crops. Also, it studied their effect on both soils and plants. The morphological study characters included plant length (cm), Active plant length (cm), fiber length (cm), No. of capsule/plant, No. of seeds/capsule, No. of benches/plant and Iodine values(IV) were increased by irrigating with sewage water than freshwater. All the values of yield components of both studied crops such as weight of plant yields (ton/fed,) weight of straw yield (ton/fed.) and weight of fiber yield (ton/fed.) increased with increasing sewage water rates, due to irrigate with 100% sewage water (T5), comparing with those irrigated with freshwater (T1). In the same context of the increases of weight of 1000 (ton/fed.), oil yield (ton/fed.), fiber % and seed oil % increased with irrigated with sewage water. Nutrient contents in flax and kenaf seeds were affected by irrigation water quality, N, P and K concentration and uptake by flax and kenaf seeds plants show increase with increasing rate of sewage water, while decrease with increasing freshwater rates. The relative increase of heavy metal concentrations and uptake in flax and kenaf seeds irrigated with 100% waste water (t5), higher than the same seeds irrigated with freshwater (T1). From the distribution of micro-micronutrients and heavy metal concentrations in all investigated plants. There is no doubt that the irrigation of flax and kenaf plants with wastewater, within safe or permissible limits and therefore possible to use such sources of this water for irrigation purposes in Egyptian territory under the codified standards and studies.
