“…Dirty water is generated from dairy parlor water and machine washings, precipitation, and water from concreted holding yards. Much research is focused on remediation of dirty water (Fenton et al, 2008). Using a material with a high phosphorus (P) adsorption capacity, P could be sequestered from dirty water and made available for farm use.…”

“…Using a material with a high phosphorus (P) adsorption capacity, P could be sequestered from dirty water and made available for farm use. In their review of remediation and control systems for agricultural wastewater in Ireland, Fenton et al (2008) identified ochre as a potential material. However, the use of ochre for this purpose has not been extensively examined (Dobbie et al, 2005).…”

Ochre found at coal mine drainage sites in the United Kingdom shows a high phosphorus (P) retention capacity with little mobilization of metals. This indicates that ochre has the potential to adsorb P from agricultural wastewaters for possible use as a fertilizer. Little research has focused on the ability of metal mine ochre to sequester P in an environmentally sustainable way. Untreated acid mine drainage from an abandoned copper-sulfur mine in the Avoca-Avonmore catchment in the south east of Ireland results in extensive low-value ochre deposition. In this study, P-amended water (50 mL) was mixed with this ochre (2.5 g) in batch experiments, and a maximum P adsorption capacity, calculated from the Langmuir equation, of between 16 and 21 g P kg(-1) was calculated. However, mobilization of heavy metals from Avoca ochre in distilled, surface, and dirty water batch experiments was observed. This mobilization may inhibit ochre's use in P removal from wastewaters.

“…Sakadevan and Bavor (1998) calculated a q max of 2.15 mg/g for zeolite in wastewater, compared to 18.3 mg/g (as DRP) in the current study. Fenton et al (2008) found that pea gravel had a q max of 0.03 to 0.05 mg/ g. Wen et al (2010) found the NH 4 + removal efficiencies by natural and NaCl-treated zeolite were 30.7 and 85.5 %, respectively, at an initial concentration of 100 mg/l. Breakthrough and exhaustion capacities for adsorption of NH 4 + ions were 3.36 and 4.26 mg/g (NH 4 + -N/zeolite), respectively.…”

Dairy soiled water (DSW) is water from concreted areas, hard stand areas and holding areas for livestock that has become contaminated by livestock faeces or urine, chemical fertilisers and parlour washings. Losses of DSW occur as point (e.g. storage, pivot irrigators) and diffuse losses (e.g. during or shortly after land application). The concept of a permeable reactive interceptor (PRI), comprising a denitrifying bioreactor woodchip cell to convert nitrate (NO 3 − ) to dinitrogen (N 2 ) gas and an adsorptive media cell for phosphorus (P) and ammonium (NH 4 + ) mitigation, attempts to simultaneously treat mixed pollutants. This study is the first attempt to test this concept at laboratory-scale. Washing of woodchip media prior to PRI operation produced low NO 3 − but high NH 4 + , dissolved reactive P (DRP) and dissolved organic carbon losses. Dairy soiled water was then treated in replicated PRIs containing woodchip in combination with zeolite or gravel compartments. In general, all PRIs were highly efficient at reducing NO 3 − , NH 4 + , DRP, dissolved unreactive phosphorus (DUP) and dissolved organic nitrogen (DON) from an influent water replicating DSW. Longitudinal and hydrochemical PRI profiles, as well as zeolite batch experiments, showed that woodchip can both enhance NO 3 − reduction and adsorb nutrients. Since woodchip is likely to become saturated, it is important to place the reactive media cell further into the sequence of treatment. Even though the majority of the dissolved nutrients were mitigated, the PRIs also emitted greenhouse gases, which would need further remediation sequences.

“…More concentrated effluent is considered to be slurry and is stored separately. Dairy-soiled water contains high and variable amounts of nutrients, as well as other constituents such as spilt milk and cleaning agents (Fenton et al 2008). Its composition is inherently variable due to the different facilities and management practices that exist on farms, seasonal changes in weather, and management practices (Ryan 1990).…”

Amendments with the potential to reduce phosphorus (P) losses from agricultural grassland arising from the land application of dairy-soiled water (DSW) were investigated. Optimal application rates were studied, and associated costs and feasibility were estimated. First, batch tests were carried out to identify appropriate chemicals or phosphorus sorbing materials to control P in runoff from DSW. Then, the best four treatments were examined in an agitator test. In this test, soil-placed in a beaker-was loaded with DSW or amended DSW at a rate equivalent to 5 mm ha −1 (the maximum permissible application rate of DSW allowable in a 42-day period in Ireland). The soil was overlain with continuously stirred water to simulate runoff on land-applied DSW. Optimum application rates were selected based on percentage removal of dissolved reactive phosphorus in overlying water and the estimated cost of amendment. The costs of the amendments, per cubic metre of DSW, increased in the order: bottom ash (1.55 €), alum (1.67 to 1.92 €), FeCl 2 ·4H 2 O (3.55 to 8.15 €), and lime (20.31 to 88.65 €). The feasibility of the amendments, taking into account their cost, potential adverse effects, public perception, and their performance, decreased in the order: alum>FeCl 2 ·4H 2 O> bottom ash>lime. Amendments to DSW could be introduced in critical source areas-areas where high soil test P and direct migration pathways to a receptor overlap.
