“…This may be due to accumulation of less soluble salts in the tope soil layer and possible formation of organic acids due to biodegradation of organic compounds in soils. These results are in accord with Belyaeva et al [9] who found lower pH in the top soil due to addition of biosolids.…”

“…They reported that the attention was given to researches related to plant nutrient uptake, particularly nitrogen and phosphorus (including reduced phosphorus uptake in alum sludge-amended soil); the risk of heavy metal uptake by plants, specifically cadmium, copper and zinc; the risk of pathogen contamination in soil and grain products; change of soil pH. Belyaeva et al [9] investigated the effects of adding biosolids to a green waste feedstock (100% green waste, 25% v/v biosolids or 50% biosolids) on the properties of composted products. They found that addition of biosolids to the feedstock increased total N, EC, extractable NH(4), NO(3) and P but lowered pH, macroporosity, water holding capacity, microbial biomass C and basal respiration in composts.…”

This study investigated the effect of treated wastewater (TWW) irrigation on growth of Chinese cabbage and corn and on soil properties in Gaza Strip, Palestine. Chinese cabbage and corn were planted in winter and summer seasons respectively in a sandy soil. The experimental design was a randomized complete block using 2 treatments with 4 replicates. Soil samples were collected from 0.0 -120 cm depths from all plots and analyzed for pH, electric conductivity (EC) and nutrient contents. The plants were irrigated with either TWW or fresh water (FW) fortified with NPK, while control used drip irrigation system. The biomass (total fresh weight of the plants) was used as an indicator of the plant yields. Concentration of heavy metals on plant leaves was determined by Inductive Coupled Plasma Analyzer (ICP) and was taken as an indicator of plant quality. Biomass of Chinese cabbage and corn grown in plots irrigated with TWW was higher than those grown in plots irrigated with FW. These results indicate the ability of TWW supplying the necessary nutrients for plant growth. Heavy metal content in plant leaves in all treatments (TWW and FW) was nearly similar and below EPA standards, indicating high quality of plants. Soil analysis showed great changes in soil properties due to irrigation with TWW. The interesting outcome of this study is that TWW is an effective source for plant nutrients. It is encouraging to reuse TWW in agricultural system after full treatment.

“…This could be attributed to the accumulation of soluble sulfates and phosphates ions in sludge top soil layer and possibility of organic acids formation due to biodegradation of organic compounds in soils. These results are in accordance with Belyaeva [32] who found lower pH in the top soil due to adding of bio-solids. Heavy metals in Table 4 indicate that concentrations of Ni, Cu, Pb and Ni in sludge, soil and soil/sludge are below safety levels.…”

71T REATED effluent from wastewater treatment plant (WWTP) offers significant water demand in all areas of activities in rural farm. This research evaluates the reuse of secondary treated wastewater (STWW) for irrigating crops, fresh vegetables and feeding fish farm. Physico-chemical, heavy metals and cytogenetic have been investigated. Intensive analyses of crops seeds, vegetables components, soil, dried sludge and fish organisms have been carried out. Results showed that the characteristics of secondary treated wastewater can be used for crops plantation and fish farming. Cytogenetic studies using Alliums' bio-tests were investigated. The concentrations of each: Cr, Pb, Co, Se, Ni, Cu, and Zn in STWW was less than 0.1 mg/l. Carbon content, nitrogen, and phosphorous were: 6.0; 1.2; and 0.1 mg/l, respectively fulfilling the requirements C: N: P ratios for plant growth. Results showed also that the irrigated crops and vegetables exhibited good growth. Analyses of roots, stems, leaves, seeds and sludge showed metals concentrations were within the permissible range. Tilapia fish showed noticeable vitality. Parasitological examination of fish revealed no parasitic cysts detected in the skin, gills and intestine, respectively. It showed no bacterial strains isolated from fish tissues. Macroscopically parameters as root length and shape look normal and healthy, while microscopically parameters showed no change of mitotic index, RDR, phase index, chromosomal aberrations of the bioassay plant tissues and do not stimulate specific type of chromosomal aberrations as well as percentage of chromosomal aberrations. All studied parameters were found in normal limits when compared with control values. This indicated the efficiency of the treatment system; hence STWW has no mutagenicity or cytotoxicity effects. Examined parameters in this study were found in normal limits if compared with trigger levels of treated wastewater.

“…Hence, reducing the time required for green waste composting and improving the quality of the compost have become important goals in the use of composting for GW valorization. To this end, several authors have opted for various solutions like the addition of readily decomposable materials, such as animal manure and grease trap waste in order to initiate an intense microbial activity [5,6], biosolids to improve on the microbial activity and GW biodegradation [7] or suitable lignolytic and cellulolytic microorganisms inoculation as a technique to accelerate the composting process and improve on the quality of the end product of the process known as compost [8]. Indeed, many reports have tackled the beneficial impact of fungal inoculation during GW composting and focused acceleration of compost maturity and to improve on its quality.…”

Lignin complexity molecule makes its biodegradation difficult during lignocellulosic wastes composting. So, the improvement of its biodegradation has usually been considered as an objective. This study aimed to determine the impact of Trametes trogii inoculation on organic matter and particularly on lignin and cellulose during green wastes co-composting with olive mill waste water sludge and coffee grounds. Three types of heaps (H1, H2 and H3) were investigated during 180 d. H3 and H2 were inoculated at the beginning of the process (t0) and 120 d later (t120), respectively while H1 was the control. Results showed the absence of pH stabilization in H3 during the first month. Also, in this period we observed a faster degradation of some easily available organic matter in H3 than in the other heaps. After 120 d, a better cellulose decomposition (25.28%) was noticed in H3 than in H1 and H2 (16%). Inoculation during the second fermentation phase induced supplementary lignin degradation in H2 with a percentage of 35% against 23 and 26% for H1 and H3, respectively. For all the runs, a Fourier Transform Infrared analysis showed aliphatic groups' decrease, OH groups' increase and lignin structural modification.
