Blending desalinated water with surface and/or ground water may result in water that has a negative precipitation potential with respect to CaCO3(s), rendering it chemically unstable. In this paper a simulation tool for calculating the pH and calcium carbonate precipitation potential (CCPP) values a

With an increase in using seawater, saline sewage is necessarily disposed of to protect the ocean. The objective in this work is to evaluate the effect of influent salinity and inhibition time on short-cut nitrogen removal from real domestic saline sewage, and to detect the performance of nitrifiers

Investigations were carried out to develop the best sustainable management system for domestic wastewaters. Sewer systems have a crucial significance within the current concept of wastewater management. It is suggested that sewer lines may be used as biological reactors to reduce pollution loads. Th

This research is focused on evaluating the effects of applying treated wastewater on citrus trees. Two experimental plots irrigated with two different treated wastewater effluents were compared. The experimental sites were located in Murcia, southeastern Spain. The first experimental plot was locate

Urban wastewater from secondary treatment is rich in compounds of nitrogen, phosphorus, and other nutrients. The elimination of such compounds, in the few cases in which it is carried out, is achieved through tertiary treatment. The development of an alternative study is proposed on a tertiary treat

A recirculating vertical flow constructed wetland (RVFCW) has been developed for the treatment of grey water. The overall aim of this research was to apply the RVFCW, a decentralized, small-scale system, to the treatment of domestic wastewater (DWW), modifying it, where necessary, to produce effluen

Sanitation techniques that are low cost and non-conventional are the adequate solution for the treatment of wastewater for small communities in rural areas. This work presents the experience of the ONEP used in some small and medium sized communities. Also, within the framework of the sanitation pro

Meranti tree sawdust, an inexpensive material, is currently being investigated as an adsorbent for the removal of Cu(II) and Pb(II) ions from aqueous solutions. In this work, adsorption of Cu(II) and Pb(II) ions on Meranti tree sawdust has been studied by using batch techniques. The equilibrium adso

In this work, a humidification–dehumidification process is considered as an advanced technique to design and construct a solar water desalination system. In this system, the salt water is heated in a solar collector before flashing inside an insulated chamber to be evaporated and condensed naturally
