BIOLOGICAL TREATMENT FOR REFINERY AND CHEMICAL WASTE

EC-350 is a natural formulation for use in treating wastewater containing refinery and petrochemical waste. EC-350 degrades extra cellular polymers (which cause foaming) and suppress the growth of the filamentous organisms by affecting the structure of the filaments. 

EC-350 CAN -
Remove oil deposits and prevent scum formation in holding tanks, sewers, drains and aeration basins.
Reduce unpleasant odor emissions associated with oily waste.
Increase the efficiency of overloaded systems.
Reseed after plant upset.
Enhance organic removal efficiency.
Lower effluent BOD, COD, and TSS.
Accelerate the start-up of new systems and aid recovery after upsets.
Improve cold weather operation.
Aid nitrification by lowering toxicity.
Improve effluent quality.
Reduce sludge production.
Protects the environment and lower operating costs by reducing chemical consumption.
Compete against filaments.

Up to 5,000 gpd ½ lbs. / day for 3 days 1lb. / week
Up to 20,000 gpd 5 lbs.* 1½ lb. / week
Up to 50,000 gpd 8 lbs.* 2 lb. / week
Up to 250,000 gpd 5 lbs.* ¼ lb. / day
Up to 500,000 gpd 25 lbs.* ½ lb. / day
Up to 1 mgd 50 lbs.* 1 lb. / day

Up to 12 mgd 50 lbs. / mgd* ¾ lb. / mgd / day
Up to 100 mgd 30 lbs. / mgd* ½ lb. / mgd / day

* Spread this initial dosage out over the course of 10 days.
** Add as regularly as possible. If it is required to miss one day, add that day’s product with the next dosage.
Application rates will vary with flow rates, retention times and system variations. The rates above are for a typical, well maintained system.

ACTIVATED SLUDGE SYSTEMS
For extended aeration, contact stabilization, step aeration, oxygen activated sludge, etc., application rates are based on the average daily flow rate to the aeration basin, excluding the return sludge stream.

TRICKLING FILTER & ROTATING BIOLOGICAL CONTACTORS
Application rates are based on the average daily flow rate to the filter or contactor, excluding any re-circulating process stream.

LAGOON SYSTEMS
• For aerated lagoon systems, the application rates are based on the average flow to the lagoon.
• For facultive lagoon systems, the application rates are based on the lagoon surface area:

 Day 1 through Day 5 2 0 lbs. / acre / day
 Day 6+  2 lbs. / acre / week

• For anaerobic lagoons, the application rates are based on the total volume of the anaerobic lagoon.

 <100,000 gallons  1 lb. - 2x / week / 5,000 gal.
 >100,000 gallons  ½ lb. - 1x / day / 5,000 gal.

NOTE: For lagoons in cold climates, commence program when the water temperature is a least 50F.

PACKAGING

COMPLIANCE
Fully complies with EPA Toxic Substance Control Act (TSCA) and the rules, orders and regulations promulgated thereunder including:
a) Sections 4, 5, 6 & 7; Title 40 Chapter 1, 707.20 thru 707.75;
b) 40 CFR Sections 704.3. 710.2(e) and 720.3(c); and
c) Sections 5 and 13, reference 42FR64583
d) Does not contain marine pollutants as defined in 49 CFR 171.8. 

STORAGE & HANDLING
Store in a cool dry location - No special handling required - See MSDS

Case History 977
A 3mgd aging activated sludge system was used to treat wastewater from a Midwest refinery. In order to maintain treatment efficiencies with overloaded conditions, a regular application of 3 lbs. per day of EC-350 was used. This product addition demonstrated reduced sludge production and enabled the plant to stay in compliance with effluent standards.

Case History 1003
This refinery operates a multistage lagoon system for treating all waste waters. The system was facing major costs for expansion to meet new ammonia standards. The use of EC-350 increased treatment capacity without the added capacity improvements and effluent ammonia levels were within permitted levels on a consistent basis.
