Alken Clear-Flo® 7000 line


Below is a sampling of industrial, municipal and bioremediation problems we have solved in the past. We are constantly pushing the envelope of technology, creating new formulas and new systems to solve a wide variety of pollution problems. Do not assume that we cannot solve a situation just because it is not on this list, we specialize in custom solutions. When the other companies give on Claudia, Valerie & Ken.

 Manure Management

AM Greek distributor, BioBest used a blend of Alken Clear-Flo products (CF 7000, 7004, 7008 and 4003) by three weeks and continuing good results with lower levels of treatment for three months.

 Ethylene Glycol Treatability Study

 Factory Discharge to Municipal Waste Treatment Managed
1) A Southwestern US hair care products manufacturer had significant problems with dyes and grease overloads on an under-designed system. They were heavily fined for discharges up to 40 times the permitted levels. TPH was decreased from an average 500 ppm to an average 12.5 ppm (a decrease of over 97%) with Clear-Flo 4000 and 7100 treatment, despite a too-short retention time. (Haircare.wpd) .

 Oil Depot Station Case Study
In 2002, a large Greek Oil Depot Station's sequential batch reactor (SBR) experienced difficulties adjusting to hydraulic fluctuations in their raw wastewater, requiring microbes that could quickly adapt to changes in quantity and content of their wastestream. After one week of treatment with Alken Clear-Flo 7008, the BOD removal efficiency was greater than ninety-seven percent and COD removal exceeded eighty percent. They also experienced odors from rotting petroleum in their storage tanks. One day of treatment iwith CF 7008 added to the storage tanks resolved their odor problems.

 Paper Mill Discharging to a River
1) Mexican pulp and paper mill, Industrias Centauro, tried 5 competing products with no success prior to working with Alken-Murray distributor DEPQUI. Once their faulty aerators were fixed and/or replaced, our Clear-Flo 7005 and Clear-Flo 7008 (warm weather) and Clear-Flo 7026 (cold weather), assisted by a small application of polymer, brought this plant into compliance with their discharge permit, reducing BOD, COD, TSS and dissolved solids to meet the discharge limit for river discharge.
2) Another paper mill discharging to a river, with graph of comparison of influent vs. effluent - demonstrating protection against influent spikes with Alken Clear-Flo 7005.
