Alken Clear-Flo® Success in 

Chinese River Cleanup Project
A team of Alken-Murray Corporation technicians
from the U.S. and Europe were dispatched to China in October of 1993 to
demonstrate the potential for rapid and effective cleanup of rivers, lakes
and ponds with Alken Clear-Flo® bio-products. A drastic improvement
in sludge removal and water clarification was experienced over a span of
three weeks during which Alken Clear-Flo® 7000 (dry),
7018 (dry) and 1200 (liquid) formulas were applied,
using a locally-made bio-activator, to a prominent stretch of the Kunming
River in Yunnan, China.

Prior to Alken Clear-Flo® Application
The water in this stretch of the Kunming
River was murky and black in color with a zero dissolved oxygen reading.
The anoxic water was so heavily laden with suspended organic waste (fertilizers,
animal droppings, fish-farming by-products, septic tank seepage, direct
disposal of raw garbage) and other pollutants (such as industrial wastewater)
that the eutrophic river emitted an unbearably heavy stench. Fish and other
local fauna had disappeared some years before when the water became so toxic
that even boiling could not make it safe for the local inhabitants to use
for cooking or drinking.
After One Week of Application The facultative anaerobic bacteria in Alken
Clear-Flo® 7000 and 7018 began degrading and breaking
up the sludge at the bottom of the river bed in a process known as bio-dredging,*
clearly demonstrated by the sudden surfacing of chunks of broken-up sludge.
At the same time dangerous gases such as ammonia and hydrogen sulfide were
gradually removed in a process known as destratification.


 
During the Middle of Week #2 of Application The river current had carried away the floating chunks
of sludge (released in week #1) and the black water had turned light green
showing improved clarity. Low reading of dissolved oxygen began to register
as a side effect from the respiration of photosynthetic organisms which
could now survive in the water. Once oxygen was present, the aerobic bacteria
in Alken Clear-Flo® 1200 continued the clarification
process by further degrading the suspended organics in the water.
