Wastewater fact sheet
From Pipeline* by National Small Flows Clearinghouse. This publication has been
adapted for use in Indiana by Purdue University.
Epidemics of cholera, typhoid, dysentery, and other waterborne diseases killed thousands, and outbreaks were especially devastating in densely populated areas
Settleable solid s -Certain substances, such as sand, grit, and heavier organic and inorganic materials settle out from the rest of the wastewater stream during the preliminary stages of treatment

Wastewater Treatment Principles and Regulations Fact sheet on wastewater treatment, by Ohio State University.
Sticks, rags, large food particles, sand, gravel, toys, etc., are removed at this stage to protect the pumping and other equipment in the treatment plant
Fixed Film Systems Fixed film systems grow microorganisms on substrates such as rocks, sand or plastic
Trickling filters, rotating biological contactors, and sand filters are examples of fixed film systems
More water can be removed from sludge by using sand drying beds, vacuum filters, filter presses, and centrifuges resulting in sludges with between 80 to 50 percent water
How to Carve Marble, Limestone, Soapstone, Alabaster
A how-to page by a stone sculptor. He discusses tools, protections devices, kinds
of stones to carve, and gives tips and advice.
Sandbags You MUST have sandbags before you start carving to support your stone on while carving
I then pull the bag right side out through the opening and fill the bag loosely with white pool filter sand (beach sand tend to sift dirt out through the fabric and get the stone dirty)
For a really large stone you can build a shallow frame and pour in a layer of sand for the stone to sit on
Sanding Now comes the lousy part, sanding
(old saying!) Start with a course grade (100 grit) of a silicon carbide (wet and dry) sandpaper, diamond paper is best but it is about $30.00 a sheet
When sanding make sure you remove all scratches left by the previous paper or when you go to the next finer grit you may not be able to (or at the very least it will take much more work)
Once you get to the 200 grit (with soapstone you'll have to start around 150 grit) it is best to use wet sanding
Get a shallow pan of water, dip the paper in it (you have to have waterproof sandpaper) and sand
I then cut small strips of sandpaper which I loop over the end of the rod
By holding each end of the strip I can keep it in place while I sand

Reducing Contamination by Improving Household Wastewater Treatment
Fact sheet on septic systems and their proper maintenance, particularly to prevent
environmental contamination.
Since a small flow is sometimes difficult to see, you should drop a pinch of sand into the pipe and watch to see if the sand is carried away
If the sand is carried away, you have a continuous leak inside the home
These microorganisms are large enough to be removed by settling, or through filtration in sand beds or soil
Buried sand filter
Sand filters also improve the quality of wastewater after septic tank pretreatment
Filters consist of 2 to 5 feet of sand (or other media) in a bed equipped with a distribution and collection system
Chlorine, iodine, ozone and ultraviolet light systems are available to treat good quality effluent, such as that from properly functioning aerobic units and sand filters
Unsuitable sites are those with impermeable soils, shallow rock, shallow water tables, or very permeable soils such as a sand or gravelly soil
Troubleshooting Checklist
A guide for problem solving with drip or trickle irrigation systems.

It may contain sand or chemical precipitates
Check pressure reading on gauges number 1 and 2 on either side of primary sand filters and if the difference in pressure is 5 lb or greater, the filters need to be backwashed
If pressure readings on both gauge number 3 and 4 are low, the primary sand filters may be clogged, or there may be a break in the mainline prior to that point, or the pump may be defective

Protozoan Houses
Shells, tests, gelatinous envelopes and other protozoan body coverings are
discussed in this article from Micscape.
Some species cement tiny sand grains together to form a pattern consistent for that particular species
Some species are less fussy and will incorporate sand grains, diatoms, desmids, and bits of debris into the shell construction
Testate amoeba, Arcella vulgaris Image © Jan Parmentier 1998 For a first venture, I suggest looking at some samples of marine beach sand
Place a small quantity of the sand in a small plastic Petri dish
Using a dissecting needle, one can sort the sand and separate out any foram shells
Some sand samples will prove to have virtually no forams, while others will provide a rich variety
Whenever you hear about friends traveling, if only a few miles up the coast or to some exotic location halfway across the world, ask them to bring you a couple of small vials of sand
Often such sand samples, even if they don't provide forams, do contain small jewels from other organisms
Pool Terminology
Commonly used terminology specific to a "residential pool language" with a focus
on chemical and water balance definitions and pool structure and equipment ...
A small amount of alum can also be used as a sand filter additive
FILTER MEDIUM: A finely graded material, such as sand, diatomaceous earth, polyester fabric or anthracite coal that removes suspended particles from water passing through it
GUNITE: A dry mixture of cement and sand mixed with water at the "gun"; hence the name
LATERALS: Elongated, capped plastic nipples at the bottom of a sand filter which are slotted to allow for water passage while keeping the sand in the filter tank
