The effects of the treated municipal wastewater (TMWW) on the essential nutrients interactions in the various plant parts of Brassica oleracea var. Italica (Broccoli) was studied, in comparison to the fresh irrigation water, denoted as “control”. The experiment was based on a randomized block design

Wastewater treatment performance of the combined process of upflow anaerobic sludge blanket (UASB) reactor and sequencing batch reactor (SBR) was studied. An experimental study has been conducted investigating the performance of the system under different operating conditions. Three experimental run

This paper describes the interaction and removal of some heavy metal ions such as Ni(II) and Cu(II) from aqueous solution at constant pH (6.0) and 0.01 M NaClO4 ionic strength using raw clay mineral. The experimental results were analysed in terms of Langmuir, Freundlich and Redlich–Peterson isother

Five submerged macrophytes, C eratophyllum demersum , E lodea canadensis , P otamogeton crispus , Myriophyllum spicatum and Vallisneria spiralis were selected and their relative growth rate (RGR) and the capacity of removing phosphorus in greenhouse were evaluated by hydrotropic experiments of two s

As polyacrylonitrile (PAN)-based membrane plays an important role in the processes of pervaporation, bioproduct purification and water treatment, this study aims at better understanding the hydrolysis differences by using different alkaline species, and how the hydrolysis degree affect the subsequen

The largest environmental challenge that Jordan faces today is the scarcity of water. Current water use already exceeds renewable supply. Many methods have been suggested to increase the sources of water supply; one alternative source is rainwater harvesting. Rainfall harvesting from rural/urban cat

The removal of nitrate from aqueous solutions of a synthetic medium and groundwater was examined using various aquatic plants, such as water hyacinth, water lettuce and salvinia. Water hyacinth reduced the nitrate level to 64% in a synthetic medium containing 100 mg l–1 of nitrate. The efficiency of

The effect of single salts sodium and potassium chlorides on the distribution of the solute components acetone, 2-propanol and methanol between the two coexisting and equilibrated liquid phases of the solvent components (water + toluene), (water + cyclohexane) and (water + xylene), respectively, are

In this paper, we present a geometrical model to calculate the radiation reflected from an external reflector inclined backwards and then absorbed onto a basin liner of a basin type still. The effect of the inclination of the external reflector on the distillate productivity of the still with both t

This study focused on reducing membrane fouling by adding different adsorbents (powder activated carbon (PAC), zeolite) or coagulants (polyamide, polyaluminum chloride) in a microfiltration process treating anaerobic digestion effluent. The results indicated that the magnitude of fouling reduction w
