Colombia’s main water bodies have been seriously polluted due to mismanagement of domestic, agricultural, and industrial wastewater. While the country’s wastewater infrastructure has expanded in the past decades, the selection of the existing treatment technologies has excluded important aspects that could compromise their sustainability. Colombia and similar countries are in great need for ine...

This paper presents the results of five years monitoring of an experimental wastewater treatment plant in southeast Brazil, comprised of a UASB reactor followed by a submerged aerated biofilter (BF) (field scale) and shallow polishing ponds (pilot scale). Three ponds in series achieved high quality effluent standards in terms of ammonia and E.coli, but a fourth pond did not result in further ef...

Abstrak Kota Jakarta merupakan kota metropolitan yang tidak lepas dari permasalahan lingkungan seperti adanya timbulan air limbah domestik. Air domestik di salah satunya diolah dengan waste stabilization pond (WSP) dan sistem terpusat. Peningkatan jumlah pelayanan berubahnya karakteristik dapat mempengaruhi kinerja WSP. Tujuan studi ini adalah untuk mengevaluasi pengolahan WSP Jakarta. Adapun p...

The stabilization of swine wastewaters from swine confined housing by the combination of a upflow anaerobic sludge blanket (UASB) reactor and waste stabilization ponds is a viable alternative to minimize the environmental impact caused by inadequate disposal of swine wastewaters. In the present study, the polluting load of pre-decanted swine wastewater treated with a series of two 0.705 m(3) UA...

Wastewater effluent from aquaculture ponds can affect aquatic ecosystems. To mitigate this problem, we designed 2 sets (southern and northern) of land-based and farm-scale sequential integrated multi-trophic aquaculture (IMTA) systems in order to reduce water pollution and to diversify and optimize aquaculture products in coastal southern Taiwan. In each system, the 1st pond cultivated milkfish...

The traditional practice of utilizing wastewater into fish pond is a unique example of sustainable socio-economic development pertaining to resource recovery in the Eastern Kolkata wetlands, a Ramsar site in India. This paper revealed the stress of urban pollution and poor land use planning on the world’s largest natural wetland. This is the first time to critically evaluate dynamics of oxygen ...

Regular concentrations of hard detergents in domestic wastewater do not affect algal growth in a high-rate-oxidation pond. The addition of nonionic hard detergent at concentrations above 60 mg/liter decreased the algal concentration in the batch culture, and complete lysis of algal cells was observed within a few days at a detergent concentration of 100 mg/liter.
