Russ :
Here is the info on limestone pellet binders. While I see why it may concern someone who is using one of the binders with gyp. to clear a pond it does not look like they would cause a problem when used for acidity reduction. The binders add material to the water col. but are natural and dissolve. It looks like they are made of wood ,or plant or natural material.
3. DESCRIPTION OF BINDERS
Binders and their properties have been previously described in detail in various
articles including previous Mars Mineral papers (see reference list). Below is a brief
description of general binder types:
Lignosulfonate – A cellulose-based organic component of trees that comes as a byproduct
of the paper making industry. It is generated by a chemical pulping process and
is a non-toxic fluid with levels of dissolved and/or suspended solids. Lignins from the
sulfite pulping process are called Lignosulfonates and will dissolve in water. They are
used for their binding, dispersing, and emulsifying properties. Since the source of lignin
is trees, their physical properties will vary by the type of trees processed (i.e. hardwood,
softwood, etc.).
Brewex – An organic modified starch brewery by-product containing glucose, maltose,
and maltodextrin. It is an evaporative product derived from beer production residuals
containing the above carbohydrates, protein, and water.
Molasses – An organic by-product of cane or beet sugar refining. It is a residual heavy
syrup left after the crystallization process. Cane molasses is derived as a by-product
from fermentation industries (which use cane molasses) or from the production of
alcohol, yeast, citric acid or other fermentation products.
Blends - Blends of molasses, whey, and lignin are available and some have been
included in these tests.
