This is a sampling of pollution 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 up...call on Claudia, Valerie & Ken.

English Abstract: Recently some live organisms have appeared in the market, designed as waste degraders for Aquaculture. The effect of two products (Alken Clear-Flo 1000 and Alken Clear-Flo 1200) on the larval rearing of the white shrimp Pennaeus schmitti was tested. This species is commercially cultured in Brazil and Cuba. Dosages were evaluated, also the oll of the products on the water quality and the possible control of the gut epithelium scaling syndrome of the animals, known as "Bolitas" were studied. In order to analyze the results , the following have been considered: survival, metamorphosis rate, larval quality and size of the postlarvae. It was concluded that the tested products can be used even since Protozoea l. It was possible to reduce the daily water exchange from 100% to 30% in the larval rearing process, besides avoiding the presence of the gut epithelium scaling syndrome from the larvae. The products can optimize the production of P. schmitti postlarvea. Click HERE for the Spanish version of this study.

Synopsis of results: This study demonstrated reduced ammonia levels over controls and increased size, in overall length, width, and weight of the shrimp culture grown when officially expired product was applied. The liquid CF 1200 was NOT supplemented with its usual CF 1001 dry supplement, and did not show a scientifically significant difference in the COD levels versus the control ponds, although both maintained low levels.

1) The scientific report of the 1992-93 remediation of the Moulin Vert Canal using Clear-Flo 1200 for 3 months. (Arnaud.CXI) This report details the application methods, the monitored sludge reduction, and improved water quality. Ammonia was reduced from 0.02 ppm to 00.0 ppm, COD was decreased by 84%, BOD was decreased by 74%. Toxicity tests were performed and proved that there was no detectable toxicity during the treatment. 1500 cubic meters of sludge was degraded during the 3 months. Bioseeding with Clear-Flo 1200 restored the canal's capacity for self-purification as it continues to mineralize sludge, several years after treatment was stopped. Diagrams and photos illustrate this study.

2) 1993 cleanup of a stretch of the Kunming River in China with Clear-Flo 7018, 1200 & 7000 is demonstrated with photos. The anoxic water was so heavily laden with suspended organic waste from fertilizers, animal droppings, fish-farming by-products, septic tank seepage, industrial wastewater and direct disposal of raw garbage that the eutrophic river emitted an unbearable stench. Ammonia and hydrogen sulfide were decreased, sludge was broken up, and as a byproduct of hydrogen sulfide oxidation, free oxygen began to increase. (ChinaRiver1)

1) This synopsis of an article written in the Va. Lake Association in 1993, describes the successful treatment of a 7 acre fresh water lake in Virginia Beach, VA with Clear-Flo 1000. By 1998, Sylvan Lake's resident strains of algae had developed an "immunity" to Clear-Flo 1000, finding alternative routes to garner nutrition. A switch to treating the lake with Clear-Flo 1002 solved the problem, restoring clean sparkling water. (Sylvanlk.897)

6) In 1991, CF 1000 and 1200 were used to restore clean water to the 12 acre lake at Merry Oak Farm in Warrenton, VA, home to crappy, bass, swans, Canadian geese and other migratory fowl. Farm manager, Richard Mayberry, said "...in six weeks, we cleaned up our lake completely with Alken Clear-Flo. We've got absolutely no algae! Riders can water their horses here in safety because we don't use dangerous chemicals in the water." Below is a picture of the appearance of the water, before and after.

4) In 1998, Guadalajara Country Club used Clear-Flo 7000 to discourage most surface algae, but were unhappy with the green color that persisted in the water. After consulting with Claudia Velasco, VP Management of Alken-Murray, the treatment was altered. One small dose of polymer was added to a small dose of Clear-Flo 1001 to instantly clear the water. Follow up treatment with Clear-Flo 1200 with its Clear-Flo 1001 supplement has maintained clean water for this pond. BOD decreased by 97%. COD decreased by 85%. SST decreased by 98%, and phosphates decreased by 69%.Click here for Spanish version of study.
