On-site household wastewater treatment alternatives: Laboratory and field studies

On-Site Sewage Treatment Alternatives

Preface The purpose of this publication is to describe on-site technologies for treating domestic sewage where conventional means (public sewer or septic tank with drainfield) are not available. These technologies are described as alternatives in this publication. Our goal is to provide information that can be used by property owners and residents to initiate action to rectify sewage disposal p...

Bridging Laboratory and Field Studies

The method we present here retrospective review and rating of Field Operational Test (FOT) data is designed to capture both the rigor of the laboratory and the ecological validity of the field. It is tailored for studies of driver acceptance of active safety systems. The method makes it possible to leverage expensive FOT data within the confines of the laboratory.

On-site wastewater treatment and reuses in Japan

On-site wastewater treatment poses a challenging problem for engineers. It requires a balance of appropriate levels of technology and the operational complexity necessary to obtain high-quality effluent together with adequate reliability and simplicity to accommodate infrequent maintenance and monitoring. This review covers how these issues have been addressed in on-site wastewater treatment in...

On Site Wastewater Treatment Using a Functionalized Green Filtration Media Sorption Field (DIVB)

Engineered ecosystem for sustainable on-site wastewater treatment.

A pilot-scale engineered ecosystem (PSEE) operated for over 2 years in sub-tropical conditions, produced an effluent with COD (median 38 mg/L) and TSS (median 3mg/L) levels comparable to that required by the AS/NZS 1547:2000 Onsite Domestic Wastewater Management standard. Only partial nitrification was achieved as dissimilatory nitrate reduction to ammonia occurred; however the level of NH(4)-N...
