	Environmental Health Perspectives: Hazardous effects of effluent from the chrome p... @ HighBeam Research (Site not responding. Last check: 2007-10-07)
		The effect of the effluent on development of adult flies was concurrent with the expression pattern of the heat shock protein 70 gene (hsp70), both in larval tissues and in the reproductive organs of adult flies.
		Effluent samples (50 mL) were digested in a mixture of nitric and perchloric acid (6:1 vol/vol) until a clear white residue remained at the bottom of the flask.
		Effluent from the chrome plating industry was found to be highly toxic at higher concentrations, as revealed by hsp70 expression, trypan blue staining, and overall effects on the development of the organism.

	Conservation 2000 - Effective Utilization of Injected Swine Effluent (Site not responding. Last check: 2007-10-07)
		During the first year of a three-year project a continuous, long term, swine effluent study was used to evaluate the crop and soils response to injected swine effluent at rates of (0, 2,000, 4,000, and 8,000 gal/A) and a conventional fertilizer rate that is nutrient-equivalent to the 8,000 gal/A effluent rate.
		Effluent was obtained from a pit beneath a swine confinement feeding operation.
		The 1997 effluent concentration was equivalent to an application of 55 lbs/A of 0-0-60 (potash) per 1,000 gallons of effluent or 440 lbs/A of 0-0-60 at the 8,000 gal/A rate.

	Effluent Irrigation: Saskatchewan Perspective
		Effluent irrigation for economic development purposes can only be considered where long term sustainability of the site is considered possible and where appropriate monitoring measures are incorporated to quantify changes to the ecosystem.
		Effluent irrigation for disposal purposes is generally considered to be the least environmentally damaging solution to a municipal disposal problem.
		Effluent water requires a high level of treatment (large soil-aquifer recharge systems with dewatering) before the water can be reused for irrigation of vegetables to be consumed raw (Shelef, 1990).

	Biodigester effluent versus manure from pigs or cattle as fertilizer for production of cassava foliage
		Effluent was significantly better than raw manure in supporting a higher biomass yield and protein content of the foliage.
		Effluent is produced daily by the digester in relatively large quantities (50-100 litres/day from a typical family scale biodigester) and it is neither feasible nor convenient to store it more than 2-3 days.
		The effluent and the raw manure were equally effective in improving soil fertility (increased concentrations of N, P, K and carbon) during the 5 month growth cycle despite the high off-take of nutrients in the harvested foliage.

	Dairy effluent: Pond site selection
		The inclusion of effluent from other sources such as feed pads, calf pads and holding areas may also be desirable in the future.
		If the effluent is pumped away from the dairy yard, it is desirable to pump it into a turkey nest or an above ground pond which allows the effluent to gravitate out.
		An adequate area of land for effluent application is essential to avoid waterlogging and soil nutrient overload and to provide flexibility when applying effluent.

	Update on Manure and Effluent Recommendations (Site not responding. Last check: 2007-10-07)
		Effluent applications to cover Crops should be based on expected crop nitrogen removal.
		Effluent application simply substitutes soil-applied N for biologically-fixed atmospheric N. This is not luxury consumption because the N is still being used for growth and converted into protein.
		If the alfalfa variety is an N-fixing variety, then apply effluent at rates up to 50 to 60 percent of crop N removal on sands, loamy sands and sandy loams, and up to 60 to 70 percent of crop N removal on heavier-textured soils.

	EPA: Federal Register: Effluent Guidelines Plan
		Effluent limitations based on BAT are to represent at a minimum the best control technology performance in the industrial category that is technologically and economically achievable.
		EPA began development of effluent guidelines for the Transportation Equipment Cleaning industry assuming that the scope would include effluent generated from the interior cleaning of tank trucks, rail tank cars, and tank barges, and the exterior cleaning and de-icing of aircraft.

	Effluent Sampling Port Design
		The primary use of an effluent sampling port is to evaluate treatment system performance in order to verify compliance with specific discharge limits, or to compare the performance of individual systems.
		Effluent grab samples are inadequate for performance evaluations even in municipal treatment plants where there is less variation in the characteristics of both influent and effluent flow streams.
		Effluent samples are collected and then analyzed and averaged to evaluate system performance.

		Effluent can't be discharged into a wash without certain permits.
		Huber is hopeful data will show the district can put effluent into the perched aquifer and allow the reclaimed wastewater to be filtered and purified by nature in the "permeable soil layer" as the effluent makes its way to the lower aquifer.
		Otherwise, if the district is forced to recharge effluent into the lower aquifer, it would have to treat the effluent more on the surface, a costlier option.

	1. Wastewater characteristics and effluent quality parameters
		It is advantageous to consider effluent reuse at the same time as wastewater collection, treatment and disposal are planned so that sewerage system design can be optimized in terms of effluent transport and treatment methods.
		Additionally, sewage treatment techniques for effluent discharge to surface waters may not always be appropriate for agricultural use of the effluent.
		In addition to the economic benefit of the water, the fertilizer value of the effluent is of importance.

		Long-term application of dairy lagoon effluent to the same fields (typically, those closest to the lagoon within range of the traveling gun pipe system) raises concerns about excessive quantities of nutrients building up in the soil, particularly at the soil surface.
		The fertilizer value of the nutrients in the effluent can only be determined by conducting a chemical analysis through a laboratory familiar with effluent analysis.
		Although this did not remove all the nutrients applied in the effluent, the extra P and K were justified over the short term because of the initial low soil tests.
