Mitigating ammonia and greenhouse gas emissions from stored cattle slurry using agricultural waste, commercially available products and a chemical acidifier.
(Elsevier, 2021-02-05)
Bovine slurry and its subsequent storage are significant sources of ammonia (NH3) and greenhouse gases (GHGs). Chemical acidification of manures has been shown to significantly reduce these emissions. Waste products, derived ...
The role of wet wipes and sanitary towels as a source of white microplastic fibres in the marine environment
(Elsevier, 2020-06-10)
Understanding source elements of the ocean plastic crisis is key to effective pollution reduction management and policy. The ubiquity of microplastic (MP) fibres in the oceans is considered to derive primarily from clothing ...
Simultaneous adsorption and biodegradation of trichloroethylene occurs in a biochar packed column treating contaminated landfill leachate
(Elsevier, 2021-08-14)
Trichloroethylene (TCE) is a human carcinogen that is commonly found in landfill leachate as a result of anthropogenic activities. Contaminated leachate plumes may be intercepted prior to reaching groundwater and treated ...
Use of rapid small-scale column tests for simultaneous prediction of phosphorus and nitrogen retention in large-scale filters
(Elsevier, 2020-07-01)
Rapid small-scale column tests (RSSCTs) have been previously used to predict the effluent concentration of a single nutrient in large filters with good accuracy. However, in drainage waters originating from heavy textured ...
An examination of maximum legal application rates of dairy processing and associated STRUBIAS fertilising products in agriculture
(Elsevier, 2021-10-09)
The dairy industry produces vast quantities of dairy processing sludge (DPS), which can be processed further to develop second generation products such as struvite, biochars and ashes (collectively known as STRUBIAS). These ...
Evaluation of the fertiliser replacement value of phosphorus-saturated filter media
(Elsevier, 2021-01-12)
The use of filter media to adsorb phosphorus (P) from nutrient-rich waters is an effective, simple and low-cost method to recover and reuse P as an inorganic fertiliser replacement. Although it is assumed that the saturated ...
Appraisal and ranking of poly-aluminium chloride, ferric chloride and alum for the treatment of dairy soiled water
(Elsevier, 2020-04-29)
Land spreading of dairy soiled water (DSW) may result in pollution of ground and surface waters. Treatment of DSW through sludge-supernatant separation using chemical coagulants is a potential option to reduce the negative ...
Effects of substrate stress and light intensity on enhanced biological phosphorus removal in a photo-activated sludge system
(Elsevier, 2020-11-06)
Photo-activated sludge (PAS) systems are an emerging wastewater treatment technology where microalgae provide oxygen to bacteria without the need for external aeration. There is limited knowledge on the optimal conditions ...
Dairy processing sludge and co-products: a review of present and future re-use pathways in agriculture
(Elsevier, 2021-06-22)
The dairy industry is one of the largest global producers of wastewater and generates huge volumes of dairy processing sludge (DPS). There are two main types of DPS, lime-treated dissolved air floatation sludge and ...
Systematic review of dairy processing sludge and secondary STRUBIAS products used in agriculture
(Frontiers Media, 2021-11-10)
Worldwide dairy processing plants produce high volumes of dairy processing sludge (DPS), which can be converted into secondary derivatives such as struvite, biochar and ash (collectively termed STRUBIAS). All of these ...
