عادةً ما يتم ضخ حمأة الصرف الصحي في مطامر النفايات الصحية, إلا أن استخدامها في المشاجر الغابوية كسماد مخصب و محسن لخصائص التربة يمكن أن يشكل خيارا مرغوباً به, و لكن يجب أن تطبق الحمأة بحذر و ذلك لتجنب تلوث التربة و المياه. الهدف من هذه الدراسة هو تقييم الأثار الناتجة عن تطبيق حمأة الصرف الصحي الجافة على إنتاجية الكتلة الحيوية الرطبة و المخزون الخشبي في مشجر للأوكاليبتوس ذو دورة حراجية قصيرة مزروع على تربة رملية في مزرعة فديو.
Generally, sewage sludge is dumped into sanitary landfills, even though its use in forest stands as a fertilizer and soil conditioner might be an interesting option. However, sewage sludge must be applied with care to avoid soil and water pollution. The aim of this study was to assess the effects of applying dry sewage sludge on wet biomass production and wood volume of short rotation Eucalyptus camaldulensis plantation established on sandy soil in Fedio plantation.

This study was carried out during 2013 – 2015 and aimed to assess the effects of
applying dry sewage sludge on dry biomass production and wood volume of Eucalyptus
camaldulensis plantation established on sandy soil in Fedio plantation-Lattakia at A
pril -
2013.
Four experimental treatments were compared at age 22 months: SS1 (sewage sludge
3 kg/tree), SS2 (sewage sludge 6 kg/tree), MF (mineral fertilizer), and C (no fertilizer
applications). Aboveground dry biomass production and wood volume in the SS1
treatment were about 107.60 t/ ha and 121.13 m3/harespectively, MF treatment (87.52 t/ha,
96.98 m3/ha) and SS2 treatment (91.12 t/ha, 103.42 m3/ha)and higher than in the control
treatment (43.89 t/ha, 51.32 m3/ha ).
This study aims to recognize some growth characteristics of
Eucalyptus camaldulensis and the effect of climate factors on trees
growth and development. Negative trends were detected in annual
rainfall according to meterological data taken from Homs station.
The study was conducted to determine the efficiency of the aerobic treatment of primary sludge resulting from sewage sedimentation and to determine the optimum residence time by measuring the indicators of total solids, chemical oxygen demand, organic content and dewatering ability of the sludge.
The importance of this modern technology (remote sensing) follows from the fact that it allows estimating the wood stock by knowing the value of the NDVI index, which reduces the high cost and great effort needed by traditional forestry measurements.
As a result of the expansion of system of sewerage and rain water networks to serve all areas in Tartous city especially its industrial area, it was not associated with proper wastewater treatment including the separation of rainwater from sewage and
building wastewater treatment plants. With the increased number of factories in the industrial area , the population growth in the city of Tartous, the demand for industrial needs, the poor investment for networks, the clogged lines and insulting them by mixing municipal, industrial and rainwater sewage and large precipitation for Tartous city Basin, and the difficulty of discharging wastewater according with gravity to the treatment plant And the lack of possibility to drain rain water with large flows, the study of the current situation of municipal, industrial and rainwater sewage to develop solutions for it.
