Q. What will Bio T® 300B immersion cleaner clean?

A. Bio T 300B is specifically formulated for the metalworking industry. Its Immersion Cleaning powerful formula effectively cleans:

• adhesive residue
• petroleum-based oils
• water-miscible oils
• petroleum-based greases
• water-miscible greases
• wax and paraffins
• paint overspray
• printing inks – solvent and soy (water) based
• polishing compounds
• oil-based sludges
• tar
• untreated polymers
• lapping compounds

Q. Is Bio T 300B immersion cleaner caustic or corrosive?

A. Absolutely not! Bio T 300B is composed of all-natural degreasers with a neutral pH. It eliminates many of the worker safety issues that exist with caustic immersion cleaning processes. Employees who work around caustic cleaners are at risk of being burned by these high pH chemicals.

Bio T 300B is non-corrosive,and will not harm aluminum, cast bronze, chrome, copper, nickel, fiberglass, stainless steel, Teflon®, titanium or other non-metalic surfaces. Because of this, users experience prolonged equipment (tanks, pumps, piping) life and reduced equipment replacement costs.

Q. Does Bio T 300B immersion cleaner need to be heated to be effective?

A. No. Unlike caustic cleaners that must be heated to approximately 160°F, Bio T 300B Immersion Cleaner is highly effective at room temperature. Turning off the tank heater creates a significant reduction in energy consumption. With soaring energy prices, the result is a significant cost savings!

Additionally, the heating of caustics causes the release of harmful vapors into the work environment. Employees report persistent coughing and burning in their lungs from continuous exposure to these caustic vapors. Because 300B is used at room temperature, employees are not exposed to harmful vapors.

Q. What is the expected bath life for a Bio T 300B immersion system?

A. As long as proper concentration is maintained, the tank can be filtered and used repeatedly for 12 months or longer. Caustic immersion tanks must be taken out of service and drained and refilled every two to three weeks. With Bio T 300B, you simply check the concentration level and top off the tank, so the process line is never out of service.

Q. What is the proper dilution ratio for cleaning with Bio T Immersion Cleaning products?

A. A 10 to 15 percent concentration of Bio T Immersion Cleaner products in water is strong enough for most cleaning requirements. The following table provides guidelines for typical cleaning applications.

According to RCRA regulations, waste discharged is considered non-hazardous if it has a flash point above 140°F. If Bio T is diluted to a concentration of 1.5 percent as it is discharged from the plant, its flash point will be increased above 140°F. Therefore, it can be discharged as a non-hazardous waste to three weeks. With Bio T 300B, you simply check the concentration level and top off the tank, so the process line is never out of service.

Q. What is the proper dilution ratio for cleaning with Bio T immersion cleaner products?

A. A 10 to 15 percent concentration of Bio T products in water is strong enough for most cleaning requirements. The following table provides guidelines for typical immersion cleaning applications.

Cleaning Application	Ratio - Bio T 300B to Water
Adhesives, Tar, Asphalt	Full strength
Heavy Cleaning & Degreasing	1:3
Medium Cleaning & Degreasing	1:8
Light Cleaning & Degreasing	1:15
General Purpose Cleaning	1:20

Q. Does Bio T 300B immersion cleaner leave residue on parts after drying?

A. All Bio T products that can be diluted with water will leave a slight residue on parts after evaporation. Water rinse should follow cleaning with these products to remove residue.

Q. Is Bio T immersion cleaner biodegradable? Can we safely dispose of it in the sewer line?

A. Bio T 300B Immersion Cleaner is completely biodegradable and safe for the environment. The sludge produced during its biodegradation leaves a favorable environment for anaerobic organisms present in the digester used to reduce the sludge. Therefore, if materials to be cleaned with Bio T are not hazardous, the waste water generated in a cleaning process can be discharged into city sewage treatment plants. Bacteria will convert the waste into safe natural products. If materials to be cleaned are hazardous, waste water pre-treatment operations (carbon absorption, air stripping, etc.) need to be developed prior to discharging the waste from Bio T cleaning into the sewer line. Contact a local or state waste water authority for further identification and proper disposal of waste.

Immersion Tank Design
Immersion tanks should be sized to fit the parts or baskets being cleaned. Design your tank to allow several inches of clearance on all sides of the parts. This permits adequate liquid circulation and ensures parts will not hit the sides of the tank when being submerged or removed.

Immersion Tank Materials
Stainless steel is the material of choice for wash tanks containing Bio T 300B Immersion Cleaner. However, for small tanks (less than three cubic feet), high-density polypropylene (HDPP) may be used. Thick walled plastic tanks are preferable to minimize warping. Mild steel may also be used, but corrosion may occur on the tank walls above the liquid level.

Agitation
Immersion cleaning systems work best when the parts are submerged in the liquid with good agitation. Good agitation is defined as complete turnover movement of the liquid in the tank. This is accomplished by pumping into the bottom of one end of the tank and removing liquid from the top opposite end of the tank. The liquid should turn over in the tank at least once every five minutes.

Bath Maintenance Maintaining the proper Bio T 300B Immersion Cleaner concentration is critical to an effective cleaning system. Control Charts like the one shown below are used to adjust the strength of the Bio T 300B bath once the proper concentration is determined. If proper concentration is maintained, a 300B bath can be filtered and reused for 12 months or longer. The strength of the wash bath is easily determined by measuring the specific gravity and using the adjustment chart below.

Typical Adjustment Chart 150-Gallon Working Capacity/10 Percent Concentration

0.9792	13%	0	4.5
0.9777	14%	0	6.0
0.9762	15%	0	7.5
Note: Measure specific gravity with a .950-1.000 range hydrometer.

Rinse Tank Design
Parts can be rinsed by spraying them directly with water. This is accomplished by moving the parts through a tank where spray nozzles are directed on parts. If the parts have blind holes or are stacked on top of one another preventing the spray from completely removing the wash liquids, dip tanks with circulating water should be used. Mechanical agitation (up and down motion of parts or baskets) may also be helpful.

In some processes, water spots (white spots or rings) are cause for rejection. Water spots can be prevented by using deionized (DI) water.

Rinse Tank Materials
Stainless steel, HDPP or painted mild steel is recommended when constructing a proper rinse tank. For large systems (500-gallons or larger), metal tanks are preferred.

Rinse Tank Maintenance
When rinse water becomes cloudy, the concentration of organic compounds is approximately 30 parts per million and should be replaced with clean water. At this concentration, rinse water can be disposed of directly into most municipal waste treatment facilities. (Contact your local or state water treatment authority to determine allowable discharge levels for organic materials.)

Pumps
All wash tanks should be equipped with a circulating system in order to achieve effective cleaning. A circulation pump should be chosen based on several factors: size of the tank, size of piping, amount of agitation needed to give good circulation through the tank. Suggestions for choosing the proper pump relative to tank size are provided in the following table.

Tank Size, Gallons	50-200	100-200	200-300	300-500
Circulation Pump Flow Rate, GPM	50 GPM	100 GPM	100 GPM	300 GPM
Circulation Pipe Size	1.25"-1.5"	1.5"-2"	2"	2.5"
Distribution Pipe
Pipe Size	1.5"	2"	2"	2.5"
Hole Size	1/8"	1/8"	3/16"	3/8"

Pump Construction
Centrifugal type pumps are very effective and economical. To be compatible with 300B Immersion Cleaner, pumps should be constructed from stainless steel or hard plastic. Additionally, pump seals should be made of Viton, EDPM, or Kynar, or other elastomeric material such as Nitrile. Natural rubber seals such as SBR are to be avoided due to swelling and early failure.

Filters
All immersion systems should include a filter system to remove particulate and oil contaminants. Bag filters, such as FSI(POMF 0A) filters are very effective on large high flow systems. Particulate such as metal fines and other dirt contamination are easily taken out of the system to keep the wash bath clean. The bags are easily removed and disposed of as solid waste.

Bag filters using cotton or polypropylene are used to remove oil and other petroleum products from the bath. For bag filters to be effective in removing oils, the liquid flow needs to be low (less than 15 gallons per minute). High flow pumping systems cause oils to be washed off the filter media and returned to the bath. For large systems, oil can be removed from the bath by using a side stream from the main circulating lines and a smaller pump, to feed through a separate, "low flow filter" that will remove the oil from the bath.
