  Information on Application and Use
Hydro-Biodigesters (HBD)
are living organisms (bacteria) supplied as a culture. They require;
air, food, water, and a suitable climate (environmental conditions)
to grow and multiply, as we humans do. These conditions will dictate
the efficiency of the treatment and dosage rates.
Prior to application:
Wastewater systems with odor problems should be disinfected (killed)
prior to dosing with Hydro-Biodigesters. This will immediately eliminate
odor and kill the bacteria present for consumption by HBD. Standard
household bleach can be used at a rate of 1 gallon per 500 gallons
of wastewater. You must wait 48 hours for the bleach to dissipate
before seed dosing. All presence of disinfectants must be eliminated
from the system; ozone, chlorine, hydrogen peroxide, etc. prior
to use.
Initial (seed) dosage
rate:
Using dry formula Hydro-Biodigesters; mix (1) one 16 oz. package
of Hydro-Biodigesters for each 1000 gallons of water to be treated.
Liquid can be used instead at a rate of one gallon HBD to 500 gallons
of water.
Dry Formula Application:
Hydro-Biodigesters require activation with warm water. First, open
each 16 oz. package of Hydro-Biodigesters and mix it thoroughly
into 2 gallons of warm (not hot) water per package. Allow the solution
to sit for 1-2 hours. This will allow the bacteria to multiply before
introduction of product. Then introduce into all water holding bodies
(tanks) within the system to be treated. Starting Hydro-Biodigesters
growing and multiplying equally in all parts of the system will
jump-start their efficiency, precipitating breakdown of hydrocarbons
and organics upon the first application.
Liquid Formula Maintenance
dosage rate:
For closed loop systems: using our Hydro-Ultradose automatic dosing
system and Hydro-Biodigesters liquid formula, introduce (1) one
minute dose per 500 gallons of wastewater into the system every
day, seven days per week. Additional dosages or higher rates may
be required in open discharge systems.
Note:
Hydro-Biodigesters will remain active in the system until; environmental
conditions change and/or their food source runs out. Over time,
the effectiveness of the Hydro-Biodigesters will degrade. Each generation
of cells becomes less effective than the last making introduction
of new cultures crucial to effective ongoing system management.
Expectations:
• In 2 to 4 days there will be a reduction in nitrogen and phosphorus
levels.
• In 3-4 days there will be a reduction in odors.
• In two weeks organics, dissolved solids and hydrocarbons will
reduce. There should be a visible improvement in clarity and water
quality.
• In one month a noticeable reduction in accumulation of tank bottom
sludge will be found.
The following physical
and chemical parameters have been proven best for accelerated growth:
Dissolved Oxygen (DO):
Levels of at least 3 ppm (mg/l) are recommended. If an aeration
system is used this will normally fulfill this requirement. Our
Hydro Engineering, Inc. formulas contain facultative bacterial strains
which will function with or without oxygen but will metabolize or
biodegrade the targeted substance 5 to 7 times faster in the presence
of oxygen.
pH Levels:
A range of 5.5 to 9.5 is allowable. Optimum growth rates will occur
from 6.6 to 7.4.
Temperature:
Temperatures of 70 to 90 degrees (F) will provide the optimum conditions
for growth. A full range of 45 to 150 degrees (F) will allow the
product to remain active. Sustained temperatures above 150 degree’s
(F) will cause cell death. Below 45 degree’s (F) cell growth will
slow and stop but this will not kill the cells.
Nitrogen:
Hydro Engineering's cultures require at least 5ppm nitrogen. Doubling
time (reproduction rates) will be shortened at 20 ppm in nitrogen
content.
Salinity:
Hydro Engineering's cultures have been proven effective in both
marine and fresh water.
Toxic shock:
Hydro Engineering’s microorganisms have proven to be quite resistant
to toxic chemical shocks including sudden influxes of petroleum
hydrocarbons, chlorinated compounds, cyanides, and heavy metals.
When chemicals of known
bactericidal concentrations are present in the wastewater contact
Hydro Engineering for consultation before treatment.
