management of unconventional water management in agricultural lands reduces environmental risks and increases its productivity. the purpose of this study was evaluating and comparing the effect of wastewater, saltwater and brackish water on some soil physical and chemical properties. for this purpose, five study sites including control area, irrigation with saltwater, brackish water wastewater ...

Intensification of swine production in the U.S. and around the world requires advanced manure management. For swine manure management in the state of North Carolina, one system met all of the required advanced management criteria, and it was qualified as an environmentally superior technology. This investigation was part of the testing for this superior technology. The objectives of this invest...

Household wastewater, especially from conventional septic systems, is a major contributor to nitrogen pollution. Alternative household wastewater management technologies provide similar sewerage management services but their life cycle costs and nitrogen flow implications remain uncertain. This paper addresses two key questions: (1) what are the total costs, nitrogen mitigation potential, and c...

Groundwater recharge with reclaimed municipal wastewater presents a wide spectrum of technical and health challenges that must be carefully evaluated prior to undertaking a project. This review will provide a discussion of groundwater recharge and its management with special reference to health and regulatory aspects of groundwater recharge with reclaimed municipal wastewater. At present, some ...

abstract population increase, limitation of water resources, and increasing volume of municipal wastewater, has caused the necessity of wastewater reuse. application of wastewater on soils seems to be the most economical method of its disposal and by percolating wastewater through the soil, its chemical quality is improved. for this purpose, a greenhouse experiment was carried out with polyethy...

Water pollution by wastewater discharge can cause the problem of disinfection byproducts (DBPs) in drinking water supply. In this study, DBP formation characteristics of soluble microbial products (SMPs) as the main products of wastewater organic biodegradation were investigated. The results show that SMPs can act as DBP precursors in simulated wastewater biodegradation process. Under the exper...

Technologies to treat wastewater are now well established and are capable of producing almost any degree of purification. The main issue surrounding the selection of a given process lies in deciding which is the most appropriate and applicable technology for the particular social, political and economic environment. This paper concentrates on the development of the municipal wastewater treatmen...

Local utilities often face problems of local industrial wastes, storm water disposal due to existing strict regulations. For many local industries, the problem of wastewater treatment and discharge into surface reservoirs can’t be solved through the use of conventional biological treatment techniques. Current discharge standards require very strict removal of a number of impurities such as ammo...

Leather industries are key contributors in the economy of many developing countries, but unfortunately they are facing serious challenges from the public and governments due to the associated environmental pollution. There is a public outcry against the industry due to the discharge of potentially toxic wastewater having alkaline pH, dark brown colour, unpleasant odour, high biological and chem...

Water is one of the most valuable and necessary resources on this planet, and the demand rate is increasing greater than the supply rate. In response to rapidly growing water needs, we must become more efficient with our water usage. As agriculture is one of the primary uses of potable water across the globe, increases in efficiency in this aspect can have substantial impact. Smarter management...
