Treatment Chemicals

Coagulants

Chemicals directly or  indirectly used to begin allowing stuff in water that would not come together under normal circumstances.  Their use depends on how acidic or basic the water is, the types of stuff to be removed, temperature, etc.  

PAC (poly-aluminum chloride)

ferric chloride

ferric sulfate

sodium hydroxide

magnesium hydroxide

aluminum chloride

polyamine

aluminum sulfate

aluminum chloride

sodium aluminate

sulfuric acid (aid)

Flocculants

Normally, once coagulants  begin bringing stuff in the water together, flocculants are added to make those particles both bigger and stronger to make their removal easier.  One exception to this is dewatering sludge.  Often times sludge is dewatered with flocculants only , though the use of a coagulant may result in less sludge particles returned to the treatment system and/or drier sludge with less water in it.

dry and emulsion cationic polymers

dry and emulsion anionic polymers

dry and emulsion nonionic polymers

monomers

DADMAC

Bio-augmentation

This is used mostly to help biological processes to begin, be more complete or to help processes become more economical.   The microbes that make up the bio-augmentation aids are typically those same microbes that are normally occurring in nature, these microbes are just more concentrated. 

treatment system (nitrifiers) 

methanol (aid)

aerobic (sludge reduction and stabilization)

anaerobic food supplement (sludge reduction and stabilization)

collection system (degreaser - control grease before treatment plant)

enzymes

anaerobic micronutrients

Final Effluent Disinfection and De-chloriation

These chemicals are added to inactivate many of the pathogenic bacteria.  Once disinfection is completed, de-chlorination chemicals are added to remove enough of the excess chlorine to make the water less hazardous to the things living in the receiving waters.

sodium hypochlorite (bleach)

sodium bisulfite

HTH (granular - calcium hypochlorite)

chlorine tablets (tablet - calcium hypochlorite)

de-chlor tablets (tablet - calcium bisulfite)

defoamer (aid)

pH Adjustment

Many times chemicals added to water to treat or remove pollutants cause the pH to either decrease or increase to the point where it has a negative effect on the receiving waters.  To help fix this problem, chemicals are added to increase or decrease the pH as needed.  Another use for pH adjustments is to make conditions more consistent with the pH range that the treatment chemicals work best. 

soda ash

phosphoric acid

hydrochloric acid

acetic acid

citric acid

nitric acid

potash - potassium hydroxide (dry)

potash - potassium hydroxide (liquid)

magnesium sulfate

sodium hydroxide (caustic)

calcium hydroxide

calcium oxide (Quicklime)

calcium carbonate

sodium bicarbonate

lime

General and Industrial Treatment

These are somewhat general and are used to fix some very specific issues that may help some of the other treatment chemical groups.

sludge conditioners

activated carbon

odor control agents

hydrogen peroxide

diatomaceous earth

calcium chloride

surfactants

phosphates

solvents

This list is not all inclusive, but does provide a good idea of the range of chemicals we offer.
