Waste Water


Control of Algae in Waste Water


SCI-62® will control 90 to 98% of the micro-organisms encountered in reservoirs, ponds, lagoons, and will do so more cost effectively than any other chemical. SCI-62® is a liquid and comes packaged ready for use. It can simply be added to a body of water by pouring in the needed amount or sprayed onto the surface. When applied at the proper time and according to the directions in the proper amounts, SCI-62® is non-injurious to useful plant and animal life and is often missing in everyday diets. Deficiencies of copper are generally added as a nutrient to most diets. Potable drinking water treated with SCI-62®, for example, is an excellent source of necessary copper and if applied according to directions will never exceed the amount of copper needed as a minimum daily requirement for humans, animals or plant life.

Waste Water Treatment Control Information

Treatment of waste water is normally more difficult than for potable water regarding the control of algae and bacteria, because the amount of nutrient waste entering the waste water facility creates a higher growth of algae.

If not controlled, the algae will contribute significantly to the waste water operator’s problem by impeding the bacterial action that would normally solve decomposition and odor problems.

Chem-A-Co, Inc. has an answer to solving uncontrollable algae growth without over destroying beneficial algae. Other treatment methods do not have this type of control. It’s either all or nothing, and total eradication of algae and bacteria is not the answer to achieving a healthy waste water facility.

Control your waste water facially compliance requirements:

  • BOD reduction
  • TSS (Total Suspended Solids)
  • pH reduction caused by an algae bloom
  • Odor reduction by increasing beneficial bacteria action
  • Will meet compliance standards (DMR’S)

Initial Treatment for waste water

1 Acre foot = 326,000 gallons of water

For each acre-foot of waste water it will require a dosage for each surface acre. Example: 1-acre lagoon 4 feet deep will require this amount for treatment.

1 acre ft =\ 326,000 gallons x 4 ft deep = 1,304,000 gallons of waste water.

Divide by \ 60,000 gallons = 21.7 gallons of SCI-62® Algicide/Bactericide.


i.e.: 300,000 gallons flow per day x 7 days = 2,100,000\100,000 gallons = 21 gallons per week maintenance treatment.

  • If alga concentration is heavy, the pH must be checked before applying SCI-62® if pH is above 8.5 technical assistance will be required.

SCI-62® will reduce anaerobic gas producing bacteria, reduce gram-negative bacteria such as fecal coliform, and enhance facultative and aerobic bacteria.

SCI-62® puts the waste water operator back in control of his waste water facility.


To properly control microorganisms in flowing water where bulk treatment is not feasible, a continuous injection system should be used.

Two methods of injection are recommended: Gravity dropping from a regulating valve that in turn can be converted to “Pints per Million Gallons of Water” or an approved injection pump calibrated to “Pints per Hour per Million Gallons of Water” are both accepted. These are practical and economical methods. The agitation provided by moving water is all that is required for complete dispersion of the SCI-62®. The injection pump system will more often be accepted when applying SCI-62® into a fresh water transfer pipe. The dripped system is much more economical and practical to use if it can be applied to a non-pressurized system before a pump lifts the water and pressurizes it.


For lower volumes of water production, it may be necessary to dilute the SCI-62® with water so a lesser amount of SCI-62® can be added with a drip system. A range of 5 to 60 drops per minute is easily obtained and the most accurate. For an example: If only one per dropper minute of SCI-62® was required for a particular application, one gallon of SCI-62® mixed with 9 gallon of water, would allow the one drop per minute to increase to 10. This would allow a much more accurate measurement of ten drops per minute measurement verses only one drop per minute.

Even in larger volumes of water that are measured in cubic feet per minute (CFM) or cubic feet per second (CFS) it may be necessary to dilute so that 5 to 60 drops per minute may be achieved.
