Recent studies by Weston and Stack had indicated that a turbine aerator could be added to an oxidation pond to increase the rate of oxygen transfer.

Ice caused the aerator to overload, straining the drive belts.

The slippage of the drive belts caused the aerator to slow down and reduce oxygen transfer as well as the mixing of the raw sewage.

The data given in Table 2, show the routine operation of the aerator.

Some units require manual methods for periodic aeration of the solid mass such as rotating a drum inside the unit or working an " aerator rake " through the mass.

Boxed wine and vacuumed sealed wine can be aerated through the use of a single glass aerator.

Variations in aerator speeds during the latter two months of this study caused increased mixing and increased oxygen demand.

The pilot plant was equipped with a 3-hp. turbine aerator ( Figure 2 ).

The raw sewage was introduced directly under the turbine aerator to insure maximum mixing of the raw sewage with the aeration tank contents.

The periods of high effluent BOD occurred during cold periods when operational problems with the aerator resulted.

One of the important aspects of this study was to determine the oxygen transfer relationships of the mechanical aerator.

An extended cold spell caused ice to build up on the aerator which was mounted on a floating platform and caused the entire platform to sink lower in the water.

Available for purchase is a screw-on aerator.

An aerator is used to prevent an anoxic event or hypoxia.

Without an aerator, water usually flows out of the tap in one big stream.

An aerator spreads the water flow into many small droplets.

This type of test is expensive and it is unclear whether or not the filter or aerator has an effect on the toxicant.

* The MCRT is the total mass ( lbs ) of mixed liquor suspended solids in the aerator and clarifier divided by the mass flow rate ( lbs / day ) of mixed liquor suspended solids leaving as WAS and final effluent.

Specifically, it is the amount of BOD fed to the aerator ( lbs / day ) divided by the amount ( lbs ) of MLVSS ( Mixed Liquor Volatile Suspended Solids ) under aeration.

If floating grease forms into solid clumps or mats, a spray bar, aerator or mechanical apparatus can be used to facilitate removal .< ref > Water and Wastewater News, May 2004 < http :// wwn-online. com / articles / 50898 /></ ref >

At the same time an " aerator ", or fountain, was added to help pump the water round the pool and keep it clean.

A wine aerator is a small, in-bottle, hand-held pour-through or decanter top device for aerating wine.

For about a century, some variable-speed electric motors have had decent efficiency, but they were somewhat more complex than constant-speed motors, and sometimes required bulky external electrical apparatus, such as a bank of variable power resistors or rotating converter such as Ward Leonard drive.

He had a variable-speed fastball ( reaching 90 MPH ), a slider, a tough curveball, and a circle change-up as his most effective offering.

When they first married he had been working in the fields all day, and she would get in the car and drive to wherever he was working, to take him a fresh hot meal.

The tulips and the big pink peonies had been blooming along the drive, and he had walked up from the bus almost singing.

She it was who had looked to see if I was wearing shoes upon learning that I couldn't drive.

Its entire complement of non-commissioned officers on the platoon level had departed as cadre for another unit, and its vehicles were still those used in the drive across Luzon in World War 2.

Perhaps they had a car or truck and would drive him into town.

She managed a missionary drive for the church once and got the books so confused that old Mr. Webber, the eldest elder, who'd never donated more than five dollars to anything, had to cough up five hundred dollars to avoid a scandal in what Edythe called `` the bosoms of the church ''.

`` You share a refrigerator '', Mrs. Kirby had said, and somehow, at midnight, after the long drive from New York in pelting rain, that had sounded reasonable.

During his visit to the Asia-Pacific Economic Cooperation forum in Manila in 1996, he was saved shortly before his car was due to drive over a bridge where a bomb had been planted.

The first commercially sold disk drive, the IBM 350, had 50 ( not 32 or 64 ) physical disk " platters " containing a total of 50, 000 sectors of 100 characters each, for a total quoted capacity of " 5 million characters.

Bonaparte had sought to invade Egypt, as the first step in a campaign against British India whose ultimate aim was to drive Britain out of the French Revolutionary Wars.

German gains were ultimately limited by Hitler diverting forces from the attack on Stalingrad itself and seeking to pursue a drive to the Caucasus oilfields simultaneously as opposed to subsequently as the original plan had envisaged.

Brabham had a poor season, scoring only four points, and — having run his own private Coopers in non-championship events during 1961 — left the company in 1962 to drive for his own team: the Brabham Racing Organisation, using cars built by Motor Racing Developments.

Antony had hoped to use his biggest ships to drive back Agrippa's wing on the north end of his line, but Octavian's entire fleet, aware of this strategy, stayed out of range.

Motor-driven mechanical calculators had these between the drive motor and gear train, to limit damage when the mechanism jammed, as motors used in such calculators had high stall torque and were capable of causing damage to the mechanism if torque wasn't limited.

Until then, the Brewers had a rivalry with the White Sox, which had become known as The I-94 Series, as both teams are just a short drive from Interstate 94.

This style of drive had the popular nickname " Toaster Drive ", because it required the use of a knife or other thin object to pry out the stuck media just like a piece of toast stuck in a real toaster ( though this is inadvisable with real toasters ).

If a user added more than one drive to a system the user had to open the case and cut a trace in the circuit board to permanently change the drive's number, or hand-wire an external switch to allow it to be changed externally.

The main cause of the problem was that the disk drive itself did not feature any means of detecting when the read / write head had reached track zero.

Even though each 1541 had its own on board disk controller and disk operating system, it was not possible for a user to command two 1541 drives to copy a disk ( one drive reading and the other writing ) as with older dual drives like the 4040 and 8050 that were often found with the PET computer, and which the 1541 was backward compatible to ( it could read 4040 disks but not write to them since its internal Operating System was essentially the same ).

Later versions of the 1581 drive had a smaller, more streamlined looking external power supply provided with them.
