This study focused on the importance of the colmation layer in the removal of cyanobacteria, viruses, and dissolved organic carbon (DOC) during natural bank filtration. Injection-and-recovery studies were performed at two shallow (0.5 m deep), sandy, near-shore sites at the southern end of Ashumet Pond, a waste-impacted, kettle pond on Cape Cod, MA, that is subject to periodic blooms of cyanoba...

This review includes works published in the general scientific literature during 2015 on the production of bioenergy and biofuel from waste residues generated during bioethanol and biodiesel production with a brief overview of current and emerging feedstocks. A section of this review summarizes literature on culturing algae for biofuels including bioreactors and open pond cultivation systems wi...

Peat is a notoriously problematic soil having high-water content, large void ratio, and weak engineering properties. Thus, it needs to be treated before utilization withstand structural stress. On the other hand, amount of waste tires increases exponentially due high demand for vehicles. Therefore, they need sustainably recovered recycled rather than disposed or incinerated. This study aimed st...

Anaerobic digestion is an attractive method for waste stabilization with the potential generation of biogas and stabilized waste residue. Development of a treatment process at short digestion period with maximum process efficiency is the objective of this research. This paper presents the optimization performance between the combined anaerobic digestion and sequential staging concept in thermop...

Disposal of an industrial waste like flyash produced from burning of coals in thermal power stations requires a large land area. The decreasing availability of good construction site has led to the increased use of low lying areas filled up with industrial wastes whose bearing capacity is low. In-situ treatment of such industrial waste fills; in order to improve their bearing capacity with rein...

A one year study was carried out in a waste stabilization ponds system where septage and sewage are cotreated. The system consists of two septage ponds which operate alternately followed by two ponds in series which receive the combined effluent. The septage ponds also act as evaporation ponds for the accumulated sludge. The monitoring program was divided in two phases. The results of the first...
