Since experience indicates that effluents from oxidation ponds do not create major problems at these BOD concentrations, the goal for the effluent quality of the accelerated treatment system was the same as from conventional oxidation ponds.

The average volatile suspended solids in the effluent was 75 mg/l while MLSS averaged 170 mg/l volatile suspended solids.

industrial landfill present where effluent waste flowed into or solid waste was buried.

The action was brought by the U. S. Environmental Protection Agency ( EPA ) and the Massachusetts Department of Environmental Protection ( MassDEP ) because the town of Billerica exceeded allowable effluent limits for phosphorus, fecal coliform bacteria, pH, and ammonia nitrogen.

The formerly rural riverfront was transformed for industrial uses such as tanneries that could discharge their effluent into the river and ship their production by the rails.

However a final effluent of a sewage treatment works serving a large industrialised area might have a discharge where the ultimate BOD was much greater than the 5 day BOD because much of the easily degraded material would have been removed in the sewage treatment process and many industrial processes discharge difficult to degrade organic molecules.

The Queen River was for most of the history of the Mount Lyell company the recipient of mining effluent and the Queenstown sewage-which then continued into the King River and consequently the Macquarie Harbour.

This was also directed at poisonous effluent generated by the plant operations.

Polluted effluent from these factories and the growing city nearby was turning the Don and its marshy mouth into a polluted hazard.

As a result, the final effluent was a deep red colour, and were a major factor in the poor biochemical oxygen demand ratings for the river.

Major improvements, including new primary settlement tanks and tertiary treatment lagoons, were made to the treatment works, and the carpet manufacturers installed facilities to treat their effluent before it was discharged to the sewer.

This was the cornerstone 20: 30 ( BOD: Suspended Solids ) + full nitrification standard which was used as a yardstick in the U. K. up to the 1970s for sewage works effluent quality.

A copper ' laundry ' constructed by Anaconda which captured a significant part of the mineral contaminants on tin can depositories which mine effluent was directed into was no longer kept in service so that the effluent flowed directly into a deep water discharge pipe which was washed away during the 1991 floods.

The concrete plug was poured on December 20th, 2001 and the effluent turned off on December 31, 2001.

Major investment in upgrading the sewage treatment works took place, and in the treatment of industrial effluent before it was discharged to the river.

Major upgrading of the Old Whittington sewage treatment works was carried out in the late 1980s and again in 1993, and has included the addition of a nitrification plant to remove ammonia from the effluent.

Orgreave was discharging effluent with 146 mg / l of ammonia in 1985, which needed to be around 70 per cent lower to improve the river quality to Grade D, but the plant closed in 1991, and water quality has improved dramatically since.

The action was brought by the U. S. Environmental Protection Agency ( EPA ) and the Massachusetts Department of Environmental Protection ( MassDEP ) because the town of Billerica exceeded allowable effluent limits for phosphorus, fecal coliform bacteria, pH, and ammonia nitrogen.

Community sewage can also be collected by an effluent sewer system, also known as a STEP system ( Septic Tank Effluent Pumping ).

Sewage is piped to a community septic tank, with effluent discharge through an ocean outfall.

This approach is somewhat controversial because of the risks of dioxins released in the atmosphere through the exhaust gases or effluent off-gas.

A team of young chemical engineers, incorporated as NTBC tested a bio-chemical process of remediating the mine waste waters by feeding a bacterial waste stream into the effluent effectively neutralizing the acid drainage and through concentration of the mineral precipitants successfully recovered the minerals economically.

The secondary treatment standards for POTWs and the effluent guidelines are implemented through NPDES permits.

Based on the success of this new technology, industries such as Wheels India are seeking solutions for effective effluent treatment through phycoremediation.

But, even using the best of current technology, risk of spreading drug resistance in the environment through wastewater effluent, would remain.

Suspension mixed lagoons flow through activated sludge systems where the effluent has the same composition as the mixed liquor in the lagoon.

A certain vertical distance is required between the effluent level in the disposal trench and the water level where the effluent is leaving the drain field for gravitational force to overcome viscous frictional forces resisting flow through porous soil.

Septic tank effluent with soluble organic compounds passing through the biofilm forms a mounded lens atop groundwater underlying the drain field.

In order to keep up with the increase of influent wastewater produced by the ever growing city of Los Angeles, by 1957 the plant engineers had cut back treatment levels and increased the discharge of a blend of primary and secondary effluent through a five-mile ( 8 km ) pipe into the ocean.

During the two weeks when the algae disappeared from the effluent BOD's in the effluent were 18 and 16 Aj.

The two primary causes of urban stream syndrome are storm water runoff and wastewater treatment plant effluent.

Sewage treatment effluent from two communities flows into the lake, which is not monitored with such stringent controls as neighboring Skaneateles Lake, which has the purest water of all the Finger Lakes.

One on a municipal wastewater treatment plant ( in Rotterdam ), and two on industrial effluent.

Near Futog are two river isles, an effluent pulped in pond.

Between the two, the Cloaca Maxima, or Great Sewer, was effluent into the Tiber.

The suspended solids discharged in the effluent were found to be the major source of the Aj.

This can save money in three ways: lower charges for lower water consumption, lower charges for the smaller volume of effluent water discharged and lower energy costs due to the recovery of heat in recycled wastewater.

Espanola got some negative press in the early 1980s when the mill accidentally discharged toxic effluent into the Spanish River, killing fish by the thousands.

" ( c ) An effluent in order to comply with the general standard must not contain as discharged more than 3 parts per 100, 000 of suspended matter, and with its suspended matters included must not take up at 65 ° F ( 18-3 ° C.

If not fully discharged on that tide, the incoming tide would then push the same effluent up the Channel, and once again circulate around the Bay.

Typically, the effluent from constructed wetland receiving near-neutral water will be well-buffered at between 6. 5-7. 0 and can readily be discharged.

Solid-liquid separation after reaction would produce a base metal-free effluent that can be discharged or further treated to reduce sulfate, and a metal sulfide concentrate with possible economic value.

Many cities already use water from rivers that contain effluent discharged from upstream sewage treatment plants.

In addition to analytical testing for known pollutants, aquatic, whole effluent toxicity tests have been standardized and are performed routinely as a tool for evaluating the potential harmful effects of effluents discharged into surface waters.

Waitara and the Waitara River. Although the freezing works had been the economic backbone of Waitara, for over 75 years the plants had discharged blood, waste and effluent from the slaughter houses, chains and tanneries directly into the Waitara River, less than 3 km from the sea, well within the tidal zone.

The government will claim that in January and February 2012, Orica discharged effluent water containing heightened levels of cyanide into Gladstone Harbour.

This is possibly as a result of treated effluent being discharged into the lower reaches.

The Compact Oxford English Dictionary defines effluent as “ liquid waste or sewage discharged into a river or the sea ”.

All of Paisley's sewage and industrial effluent had been discharged untreated into the River Cart via its tributaries: the St Mirin Burn, the Lady Burn, the Sneddon Burn, the Espedair Burn, etc.
