“…Wheat straw, cotton stalks, grass clippings, rice straw, date palm residue, pine needles, bark, pea straw, sugarcane, and leaf debris are common organic materials used for mulching (Al-Rawahy et al 2011). Zeolite showed high capacity in adsorption and storage of metals (Al-zboon et al 2016), phosphate (Aljbour et al 2017), andgases (Al-Harahsheh et al 2014). In an agricultural field, it was reported that soil amendment with zeolite reduces the impact of saline water on barley plant due to the capability of zeolite for enhancing water and salt holding capacity of soil (Al-Busaidi et al 2008).…”

Efficient water management in agricultural sector necessitates the manipulation of all possible options for water supply and demand management methods. The purpose of this study was to determine the usefulness of using natural volcanic tuff as a soil mulching on plant and soil properties under different water levels. The experiments were performed using 1-year-old olive transplants planted in barrels filled with silty clay soil. Half of the barrels were covered with a coarse volcanic tuff, while the other samples were remained without covering and considered as control. The two sets of barrels were irrigated with four levels of water which correspond to 75%, 65%, 55%, and 45% of the field capacity. The treatments were arranged in a randomized complete block design with three replications. Results revealed that plant height, number of branches, trunk diameter, shoots length, shoot diameter, number of leaves, and plant weight for soil covered with volcanic tuff were significantly greater than control plants after the fifth growing season. The leaf water potential and relative water content of plants grown in mulched soil were significantly greater than those of control. An increase in nutrient contents of soil and plant tissues was found as a result of soil amendment with volcanic tuff. In summary, a positive influence of volcanic tuff additions on olive growth, leaves water status, and soil nutrient levels was determined.

“…Phosphate removal from water and wastewater via adsorption processes offers an alternative treatment, especially if the sorbent is economical and easily available. A considerable attraction has been paid to economic and environmental concerns to the research of applying various kinds of inexpensive sorbents, such as zeolite (Aljbour et al, 2017;Zhang et al, 2014), sludge , fly ash (Novais et al, 2016), periwinkle shell (Bello and Ahmad, 2011a), and slag (Park et al, 2007). Previous research suggests that calcite, aluminum hydroxides/oxides, and iron hydroxides/oxides are significant phosphate sorbents (Karageorgiou et al, 2007;Lai et al, 2016).…”

This work provides a simple and convenient method to manufacture the sorbent of Al-eggshell. The influence of AlCl 3 concentration and pH values as well as the dosage of sorbent and their interactions on adsorption of phosphate was investigated. Therefore, Box-Behnken design coupled with response surface method was adopted to explore the empirical model for phosphate species removal. It was observed that there is an optimal point, C(AlCl 3 )(0.29 mol/l)-pH(6.12)-dosage(6.72 g/l), for the goal of maximizing phosphate species removal. The second-order polynomial model for phosphate reduction was given asContour pictures implied that the interaction between pH values and sorbent dosage was the strongest, followed by C(AlCl 3 ) versus dosage and C(AlCl 3 ) versus pH. The adsorption of phosphate data had a good agreement with the Freundlich isotherm equation at 313 and 323 K. Otherwise, Langmuir-Freundlich model described the best fitness at the temperature of 293, 298, and 303 K. The process of adsorption of phosphate on Al-eggshell fitted a pseudo-second-order kinetic equation, which indicates the exothermic reaction. In conclusion, the present work suggests Al-eggshell as an efficient and environmental friendly sorbent for phosphate species adsorption from aqueous solutions.

“…Due to the complexity of phosphate removal processes using phosphate accumulating organisms (PAOs) under a sequential anaerobic-aerobic processes (Ramasahayam et al 2014), phosphate removal is still a bottle neck for the development of long-term recirculating aquaculture systems. Therefore, several technologies have been proposed for phosphate removal such as using natural Jordanian zeolitic tuff as an adsorbent (Aljbour et al 2016) and photosynthetic microorganisms such as algae and cyanobacteria (Zhang et al 2008;Burut-Archanai et al 2013;Rai et al 2016;Ruiz-G€ uereca & S anchez-Saavedra 2016). Using microalgae for phosphate removal is less complicated than PAOs.…”

Unicellular cyanobacterium Synechocystis sp. was used for phosphate removal in a recirculating aquaculture system. The cell harvesting was performed using chitosan solution in this study. The parameters (i.e. cell density, pH of cell suspension and chitosan concentration) affecting the flocculation efficiency of chitosan were investigated. With the optimal condition, the repeated flocculation for phosphate removal in a photobioreactor was demonstrated. The results show that the flocculation efficiency of chitosan depends on cell density, pH of cell suspension and chitosan concentration. The optimal flocculation process could be accomplished by adjusting the pH to 7.2 before adding 20 mg/L chitosan followed by pH adjustment to 7.5. With single inoculation, the sequential process of phosphate removal using cyanobacterial uptake followed by cell flocculation using chitosan with the optimal condition in the photobioreactor was successfully achieved for 12 cycles with water from a recirculating fish tank.
