EcoClear System On-Site Bioreactor

Benefits of On-Site Bioreactor

Eco Scientific, Inc. would like to introduce you to the EcoClear Bioreactor System. The EcoClear Bioreactor System is used in hundreds of large ponds and wastewater treatment lagoons worldwide to minimize the growth of algae and reduce suspended solids, ammonia, phosphorus, BOD, and pH fluctuations.

The system works by providing vast numbers of live, active, nitrifying bacteria that consume nitrogen and phosphorus (N and P) very effectively, thus out competing algae for nutrients rather than killing them with toxic chemicals that can pollute the water. The introduction of nitrifying bacteria improves performance at treatment ponds that must provide ammonia removal. The system can also benefit mechanical wastewater plants that may need to improve nitrification or general plant performance due to toxic loading, hydraulic washout, flows beyond plant design, or other conditions that contribute to inadequate treatment.

To maximize performance and minimize your cost we supply an on-site bioreactor.  The bioreactor is easy to install and operate, and produces vast numbers of fully active, nitrifying bacteria in the most economical way. While nitrifying bacteria are likely present in ponds and WWTPs, they are not introduced inSetup for 55-Gallon EcoClear System Bioreactoradequate numbers from the waste stream to enable an effective population in many facilities. Unlike BOD reducing bacteria, which are plentiful in the waste stream, nitrifying bacteria require a fully aerobic environment. In addition, the reproduction rates of nitrifying bacteria within a pond or WWTP are much lower than for other types of common bacteria. This is why the use of the EcoClear System on-site bioreactor, specially designed to grow and introduce a continuous dose of nitrifying bacteria, provides such an advantage over other biological products.

 

 

 

Installation and Operation
EcoClear System 100-300

Part I: System Installation

A. Site choice for the 55-gallon drum

The first consideration is that the system requires water and electricity. Total water use will be one half of a drum per week of tap water. Any site with access to water is suitable. Electric use is standard 110 V, and of low amperage.

A second consideration is closeness to the pond(s) needing treatment. Each week, one half of a drum of liquid (27.5 gallons) will be withdrawn from the drum and dosed to the pond. The drum should be positioned in a room or area as close as possible to the site needing treatment.

Ideally, the system should be placed indoors (workshop orshed). However, many golf courses set the system up outside at a site with water and electricity which is close to the pond(s) needing treatment. Avoid temperatures below 60 F or over 95 F.

You choice of site should be one that allows for convenient dosing from the drum to the pond(s) while fulfilling the water and electricity requirement.

B. Initial Filling of Drum

Set the drum in the location you have chosen. Then add the following:

First, add one pail of EcoClear Concentrate to the drum
Next, fill the drum to within 2 inches of the top with tap water

C. Assembly and Set Up of Heater

Your kit comes with two 300 watt heaters. One is for regular use. The other is a spare. THESE HEATERS ARE 100% IMMERSIBLE.

Before lowering the heater into the drum, set the temperature setting at 80 F. Once the temperature is set to 80 F, lower the heater into the drum so that it is near the bottom of the drum. Use any convenient fastener (cable tie, clamp, tape, etc.) and secure the cord so that the heater stays near the bottom of the drum. Be sure that the heater is positioned in the lower half ofthe drum. The reason for this is as follows. The heater MUST BE IMMERSED WHENEVER IT IS TURNED ON. Each week, one half of the drum is dosed to the pond(s) needing treatment. If the heater is placed in the top half of the drum, it will be exposed when one half of the drum is dosed, and the heater will burn out. That is why the heater must stay in the bottom of the drum.

D. Set Up and Assembly of Aerator and Air Line

Find the aerator, telescoping union fitting, air line, and air stone assembly. Attach the aerator to the air line via the telescoping union. Be sure that the air line is attached to the air stone assembly. Drop the air stone assembly into the drum.

E. Turn On Heater and Aerator

Once the heater and air line diffuser assembly are both immersed in the drum, plug in both the heater and aerators. As long as the heater is located near the bottom of the drum, and as long as the water level in the drum does not drop below the half way point, the heaters and aerators run full time, all of the time, without adjustment.

F. Add One Bag of BioPack

Once the drum is filled with EcoClear Concentrate and water, and the heater and aerators are installed and plugged in, add one bag of BioPack. The bag is NOT water soluble. Do NOT place the plastic bag into the drum. Open the bag, and dump the powder contained in the bag into the drum.

G. Aerate Drum for Seven Days Before Dose

Once all components are added to the drum, the system must be aerated for seven days before dosing to the pond(s) needing treatment.

Part II: System Operation

A. Dosing Technique

IMPORTANT: With any one dose, only one half of the drum is dosed to the pond(s), This is critically important. If more than one half of the drum is used, the system will no longer function at full potency.

The system is ready for dosing after it has been filled and has aerated for seven days. After seven days, withdraw one half of the drum contents. If the pond is close to the drum, you can usea sump pump and garden hose, and simply pump the product to the pond. Again, be extremely careful not to dose more than one half of the drum contents.

Alternately, you could siphon or pump one half of the drum to another container, which would typically be placed onto a cart and driven to the pond needing treatment.

The product can be pumped, siphoned, or transferred using any typical piece of equipment as long as the equipment is reasonably clean.

B. Refilling the Drum and Continuing Operation

Once you have dosed one half of the drum, simply refill the drum with water, and add another bag of BioPack. Once the BioPack is added, let the drum aerate another seven days, and repeat.

Each week, one half of the drum is dosed, the drum is refilled with water, one bag of BioPack is added, and the drum aerates again for seven days. This procedure repeats on a weekly cyclethroughout the algae season.  .

Installation and Operation
EcoClear System 400

Part I: System Installation

A. Site choice for the 175 gallon tank

The first consideration is that the system requires water and electricity. Total water use will be one half of a tank per week oftap water (about 85 gallons). Any site with access to water is suitable. Electric use is standard 110 V, and of low amperage.

A second consideration is closeness to the pond(s) needing treatment. Each week, about 85 gallons of activated liquid suspension will be withdrawn from the tank and dosed to the pond. The tank should be positioned in a room or area as close as possible to the site needing treatment. Ideally, the system should be placed indoors (workshop or shed). However, many golf courses set the system up outside at a site with water and electricity which is close to the pond(s) needingtreatment. Avoid temperatures that are regularly less than 55 or greater than 95 F.

You choice of site should be one that allows for convenientdosing from the tank to the pond(s) while fulfilling the water and electricity requirement.

B. Initial Filling of Tank
Set the tank in the location you have chosen. Then add the following:

First, add three pails of EcoClear Concentrate to the tank
Next, fill the tank to within 2 inches of the top with tap water

C. Assembly and Set Up of Heater

Your system comes with a 500 watt heater and thermostat with temperatureprobe. Plug the heating element into the thermostat, but do NOT plug in the thermostat yet. Insert the heating element through a 1 and 1/4 inch hole in the top of the tank. Insert the temperature probe through the same hole as the heating element was passed through. Using cable ties, securethe thermostat to the top of the tank as shown in the picture. Note: The heating element should be positioned as low in the tank as the cord allows. The heater MUST BE IMMERSED IN WATER WHENEVER IT IS TURNED ON. Each week, one half of the tank is dosed to the pond(s) needing treatment. If the heater is not immersed, it will be exposed when one half of the tank is dosed, and the heater will burn out. That is why the heater must stay in the bottom of the tank.

D. Set Up and Assembly of Aerator and Air Line

Find the aerator, telescoping plastic union fitting, air line, and air stone diffuser manifold. Place the manifold air stone assembly into the tank, while preventing the opposite end of the air line from falling into the tank. Once the assembly is lowered into the tank, this will keep the manifold located in the center of the bottom of the tank. Thread the opposite end of the air line from the inside of the tank out through the 1 and 1/4 inch opening in the top of the tank. Once this is threaded out of the tank, connect the air line via the telescoping union to the aerator.

 

Important: Always position the aerator at a resting height greater than the height of the tank. This will prevent back siphoning and aerator damage in the event of power loss and loss of air pressure.

E. Turn On Heater and Aerator

Once the heater and air line diffuser assembly are both immersed in the tank, plug in both the heater and aerators. Set the heater setting at 28 C. As long as the heater is located near the bottom of the tank, and as long as the water level in the tank does not drop below the half waypoint, the heaters and aerators run full time, all of the time, without adjustment.

F. Add One Bag of BioPack

Once the tank is filled with EcoClear Concentrate and water, and the heater and aerators are installed and plugged in, add one bag of BioPack. The bag is NOT water soluble. Do NOT placethe plastic bag into the tank. Open the bag, and dump the powder contained in the bag into the tank.

G. Aerate Tank for Seven Days Before Dose

Once all components are added to the tank, the system must be aerated for seven days before dosing to the pond(s) needing treatment.

Part II: System Operation

A. Dosing Technique

IMPORTANT: With any one dose, only one half of the tank is dosed to the pond(s), This is critically important. If more than one half of the tank is used, the system will cease to function at full potency.

The system is ready for dosing after it has been filled and has aerated for seven days. After seven days, withdraw one half of the tank contents. If the pond is close to the tank, you can use asump pump and garden hose, and simply pump the product to the pond. Again, be extremely careful not to dose more than one half of the tank contents.

Alternately, you could siphon or pump one half of the tank to another container, which woul typically be placed onto a cart and driven to the pond needing treatment.

The product can be pumped, siphoned, or transferred using any typical piece of equipment as long as the equipment is reasonably clean.

B. Refilling the Tank and Continuing Operation

Once you have dosed one half of the tank, simply refill the tank with water, and add another bag of BioPack. Once the BioPack is added, let the tank aerate another seven days, and repeat.

Each week, one half of the tank is dosed, the tank is refilled with water, one bag of BioPack is added, and the tank aerates again for seven days. This procedure repeats on a weekly cyclethroughout the algae season. If you have further questions, please contact Eco Scientific, Inc.

Larger bioreactor systems, from tanks 500 gallons to 5,000 gallons, can be designed to fit the needs of larger facilities.  Please contact ESI for more information on larger systems.

EcoBac System On-Site Bioreactor

The EcoBac Bioreactor System is set up the same as the EcoClear Bioreactor System, but the start up products, aeration time, dosing procedures, and restart are different.  

The EcoBac System does not require a liquid starting concentrate.  EcoBac powders are offered in different size bags of the dried bacteria and nutrients to start the system, depending on the size of the bioreactor.  Tap water or in some cases process water is used to fill the bioreactor, and then the EcoBac bags are placed. 

Depending on the desired result, the aeration times of the EcoBac System range from 24, 48, and 72 hours.  When the aeration cycle is complete the entire volume of the bioreactor is available for dosing to the treatment components as needed.

Contact ESI for further information for bioreactor the sizing and aeration times most suitable for your facility.
