Lake water algae as an effective treatment method for liquid waste streams with high ammonium concentrations.
Pretreatment procedure for the sustainable utilization of brewery effluent and production of algal biomass with valuable nutrients.
The Arrudas biogas project offers a valuable example of a well-functioning energy recovery project that embraces the principals of low-carbon sustainability within municipal wastewater treatment operations. Since the project came on-line in 2011 it has avoided over 6,000 tons of CO2e, emissions that would have otherwise been emitted directly to the atmosphere.
The removal or degradation of pharmaceutical compounds present in the urine or other real wastewater matrices mixed or contaminated with urine is a foremost necessity due to the frequent notifications of various multi-drug resistance based disease outbreaks in whole biosphere. Thus, these compounds are subsequently required to be removed from the urine matrix before their dissolution into the bulk or sewage wastewater streams. Therefore, urine collection at source followed by in-situ or separate ex-situ treatment has been proposed to effectively treat a limited volume of concentrated pharmaceutical compounds present in a small batch. The additional benefit of this source separated urine treatment is the possibility of efficiently recovering nitrogen, phosphorus, and potassium based nutrients.
The treatment and disposal of sludge sediments come from sewer cleaning process is the key for carbon neutrality of the whole system. This means that the sludge sediments should be recycled and beneficial reused rather than directly incineration, landfill or even laissez-faire. nevertheless, besides the environmental impacts of carbon footprint mitigation, relevant co-conflicting issues may include engineering cost, public perception, socio-economic, rules/regulations, and managerial aspects of cleaning process. They all receive excessive consideration from government authorities and stakeholders.
Carbon emissions smoked – Helpful microbes inhale CO2 through a porous cylindrical electrode and exude useful chemicals.
The objective of this technical note is to inform utility managers and technical decision makers in East Asian countries about appropriate technologies available for wastewater treatment with energy recovery processes.
The article presents a review and description of technologies for recovering Nitrogen and Phosphorus from a waste water stream. The work outlines the theoretical mechanism, concepts and results of each method.
Adaptive and dynamic policy making for sustainable recovery of various resources from wastewater streams. A case study from Amsterdam.
In this report the results of literature research and comparison
with data of case studies of full scale enhanced primary treatment units
are shown and compared to each other. Specific indicators for
the comparison are defined followed by identification of available
alternative technologies for primary treatment at municipal
wastewater treatment plants (WWTPs).
