Anaerobic ammonium oxidation processes with nitrite to N2 (anammox) has become a main focus and been widely introduced as a cost-effective biological nitrogen removal way in wastewater treatment. This paper reviews various patents, which were well developed to achieve this process, such as SHARON-Anammox, CANON, and OLAND.

This study was intended to identify and test an appropriate and effective solution for the lack of adequate wastewater treatment in these communities. The MBR system, employing a Zenon ZW-10 ultrafiltration membrane, was designed and constructed at the University of Manitoba. It was installed and tested in two phases at the Opaskwayak Cree Nation Reserve in Northern Manitoba.

In this chapter, the authors have covered several aspects of MBR, with an exhaustive overview of its operational and biological performance. Different configurations and hydraulics of MBR are presented, with attention given to the fouling phenomenon and strategies for reducing it. Also, the high quality of MBR effluent is discussed, whereas in comparison with CAS removals of organic matter, ammonia, phosphorus, solids, bacteria and viruses are significantly enhanced.

Membrane Bioreactors (MBRs) are commonly understood as the combination of membrane filtration and biological treatment using activated sludge. Development of a biofilm-MBR has been investigated combining a moving-bed-biofilm reactor with a submerged membrane biomass separation reactor. Treatment efficiencies were found to be high with the production of a consistent high-quality effluent, irrespective of loading rates on the bioreactor or membrane reactor operating modes. Membrane performance (fouling) is a function of the biofilm reactor effluent quality and varies with loading rates (HRT). Sustainable operation was found to correlate to the fate of the submicron particle size fraction throughout the treatment process.

This publication describes the operation and demonstration of environmentally sound technologies, reducing the consumption of water and targeting a closure of nutrient loops in a quarter of Hannover (including housings, a school, a church and industries). Environmental technology was combined with environmental education and awareness raising, particularly for the neighbourhood and the local youth. Applied technologies for the water cycle are: constructed wetlands, bio-reactors, mini wastewater treatment plant using rotating biological contactor technology for the greywater, rainwater reservoirs, urine diverting toilets, vacuum toilets, waterless urinals, and greywater evaporation beds. Further, block heat and solar power units were installed and ecological construction materials were used.

The following technologies were installed in the education centre “San Christoferus”: Constructed wetland for greywater treatment; compost filter for blackwater treatment; and double-vault urine diversion dehydration toilets. The aim of the project was to reduce water consumption and limit the wastewater flowing to the public sewer system, of which the largest part is discharged without treatment.

This paper describes the project of constructing a thermophilic composting site in Haiti after the earthquake in 2010. The composting facilities have treated over 500,000 gallons of human waste in the past three years, converting it to pathogen free compost, over 10,000 gallons of which has been sold for use in agriculture and reforestation projects. The experience of thermophilic composting in Haiti is unique in scale and duration and can have global implications for waste treatment in both emergency and development contexts.
