SPECIALTY BIOREMEDIATION TREATMENT

**DESCRIPTION:**
ALKEN CLEAR-FLO® 7050 is a specialized formula created to degrade "spent-phenolic caustic wastewater" and "wood preserving wastewater". ALKEN CLEAR-FLO® 7050 contains six spore forming Bacillus strains and twelve vegetative, gram-negative strains. For wastewater applications, it is wise to bench test this formula and our *Alken Clear-Flo® 7037* to see which will work best for the specific plant. *Alken Enz-Odor® 12* or 22 can be used in conjuncftion with this product to control odors generated during treatment.

**CHARACTERISTICS:**
Bacteria Count	5 Billion Colony Forming Units/gram
Appearance	Free flowing brown powder
Odor	Yeast Like

**FEATURES AND BENEFITS:**
Rapidly degrades phenolics, naphthalene and PAH's (especially pentachloraphenol, anthracene, phenanthrene, fluoranthene and carbazole Reduces further environmental damage by degrading the contaminant plume. Cultures can tolerate diesel concentrations inhibitory to many indigenous populations. Can tolerate up to 20.0 ppm concentration of heavy metals. Effective over a wide temperature range (40 to 100F; optimum 75± 10 F) Effective over a wide pH range (6.0 to 8.5; optimum 7.1 ± 0.3) Non-toxic, non-corrosive, safe to handle and store when used as directed.

APPLICATION:

ALKEN® BIO-NUTRIENT 3, containing ammonium chloride and ammonium phosphate nutrients, in a 5:1 ratio, is designed to balance the high level of organic carbon present in the targeted wastewater. The strains in this formula degrade hydrocarbons aerobically, requiring at least 2 ppm of dissolved oxygen, with 3 to 5 ppm being ideal.

Although ALKEN CLEAR-FLO® 7050 may be measured out and applied directly, as dry, loose powder, we advise rehydration of each pound of ALKEN CLEAR-FLO® 7050 in two gallons of warm (21 to 22 C / 70 F) for optimum bacterial performance, mixing bran-based powder thoroughly with water every thirty minutes over two hours. Alternatively,use an overhead stirrer to continuously mix bran powder and water for two hours, then allow to settle for 15 minutes before decanting liquid into influent section of wastewater system. Thoroughly stir settled bran into fresh wastewater and dispense into system or discard.

for general application rates for to activated sludge, RBC, floating bed recirculating or lagoon systems, designed to treat wood processing or spent phenolic caustic wastewater..

Avoid use of algaecides, herbicides, and antibiotics when using any ALKEN CLEAR-FLO® product.

Alken-Murray's authorized distributors can assist you with product selection and other treatments based on submission of the Wastewater Treatment Diagnostic Survey from the Alken-Murray Diagnostic Form Frame Set.
