Designing a New Sand Filter for a Small Operation: Sizing, Media, and Filtration Methods
The estimated flow rate for this site is 2000 m3/day. The surface overflow rate should exceed 125 m3/m2/d. What will be the surface area of the filter? You can use some leftover Ottawa sand (d10 = 0.00055m) from your last filtration project. How deep should the filter be?
Let’s make the filter 4 m x 4m.
Depth (L) should be: 1000
So, let L = 1 m; gives us: L/d10 = 1m/0.00055m = 1818 so choose 1m depth.
* Removal Efficiency = 1 – 0.29 = 0.71 = 71%
Determine the matching sizes (d10) of anthracite (

Chromatography: Methods, Phases, and Separation Efficiency
Chromatography:
Physical method of separation. Compounds are distributed between stationary phase and mobile phase – the chromatographic process occurs as a result of repeated equilibration events during the movement of the sample components along the stationary phase bed. The separation occurs due to differences in their affinity for the stationary and mobile phases. As the components exit the system, a detector identifies them based on specific properties of the desired analytes.
Stationary Phase:

Environmental Impacts- Petrodiesel–
Habitat and land destruction
Potential for oil spills as it needs to be transported Biodiesel–
Potentially carbon neutral, produces less CO2
Can be produced from waste products, Requires a lot of water to grow and wash the crops required to produce he oils, also biodegradable
Biofuel- Advantages–>
Renewable – Net lower emissions of CO2 Disadvantages–>–
Production of CO2 – Lower energy content -Uses up arable land and resources for food crops
Advantages

Definition of Land Surveying
Surveying is the science that deals with the surveying in the field of relative positions and heights as well as the size and shape of any part of the earth surface including all detail and the projection of the measured data or detail on a map against a suitable size or scale. Surveying may also include determining relative heights of different points on the earth’s surface.
What is a map or plan?
A map is both a generalized as well as reduced presentation on
