Warning boring thread: Bessemer process

[Q]

Yes, this is for a class, but it's not homework, I'm just trying to study. I know this is quite possibly the most boring thread but I'm tired and want to get this 'done' before I go to sleep.

I'm trying to think of other inventions that used science and technology/ a connection between the two.

Example: Bessemer process used chemistry / oxidation. Any other examples you all can think of?

TIA

You mean like the 1960's moon shoot pushing different tech forward? (e.g. smaller computers though still huge by modern standards)

Rotating aerobic biological filter for aquaculture. Water is collected in a spillway, channeled through a penstock and to fill a reservoir with a series of escape lines below so it cascades upon a drum making it rotate. The drum is filled filled with polyester fibers that afford lots of surface area for beneficial nitrosomonas and nitrobacter cultures responsible for breaking down ammonia to nitrite nitrogen then to nitrate nitrogen. The water collects in a pool below (the drum typically is submerged near its axis of rotation). Pickup lines run to a centrifugal pump which supplies the water to post filtering/reaction, etc. then back to the main column. There's lots of physics and chemistry going on in that system.

the basic oxygen furnace has greatly enhanced the efficiency of making steel. you'll also want to look at refinement to the aluminum processing

WTF, my brain! English, stupid translation please? I can't remember all that for my test

Or if you prefer fewer moving parts, the wet/dry sump in my aquarium.

The large biowheels are very reliable especially with a good bearing system. Some even use a motor to keep the drum moving all the time. Most reefkeepers will balk such a setup in the home as it tends to be a nitrate-nitrogen factory so the NNR plenum gained popularity. It's certainly easier to run compared to a fully enclosed nitrate removal system where CN ratio is VERY critical and flows and nitrite/DO2 levels must be constantly monitored to prevent harmful nitrite back to the system.

You don't "combine science and technology" - they are aspects of the same thing. Maybe you can use the words as labels for developing and understanding the underlying principles, vs. building a device to use the knowedge for a practical purpose.

Teeter-totter applies the principles of the lever to produce a child's toy.

Swing uses principles of the pendulum for same end.

A ramp at a loading dock uses the principles of vector analysis of Newtonian forces to raise an object vertically from one level to another.

A battery is based on electrochmical principles and dynamic equlibria. The bulb in the flashlight is based on electrical resistance to produce heat, and the Plank Black Body model that relates the output of radiation to the temperature of the hot body. The flashlight they are mounted in us many principles of electical condution, shaping metals, polymer chemistry, molding tehcnology, etc, all united to make a small temporary hand-held light source.

You're just plain scary.
I think I'm in love! :laugh:

BTW, I'm using mine on a FW tank. Works great, even if it is a little overkill.

Test over, and thanks for all the help

Trickle filters work great on freshwater systems and allow for very heavy loads. Overkill would be large downdraft fractionators with 20 foot towers but many say it "blows out" ammonia before it can even be broken down by nitrosomonas. :Q The constant saturation of O2 is very beneficial. Be wary if you heat with unvented natural gas or propane heaters though! The exchange is so effective that the elevated indoor CO2 levels will cause suppressed pH even with (over) adequate total alkalinity levels. Some marine systems can see pH in the 7.5's on turkey day when the oven is on for six hours or more. :Q In such a situation it would be beneficial to use outside air for the tower inputs as long as it's passed through a GAC contactor (at the minimum).

I saw a video of one of those being run on a very large scale and was absolutely amazed by the ingenuity.

Think Biowheel filters or other rotating drum systems for aquariams.

Would that happen to be on youtube?
