From Meb Faber:
Most of the alpha out there (or smart beta or whatever it is being called these days) is either hard to find or hard to DO. And by do, I mean it goes against everything your behavioral instincts tell you to do. Buying a stock at all time highs is hard to do, and one reason momentum and trend work. Buying a value investment is hard for many reasons.
A sewage treatment plant works to remove suspended solids
and BOD (biochemical oxygen demanding waste)-this helps to
lessen fish kill because of eutrophication or the diminishing oxygen levels which can harm marine life.
Septic system owners who have utilized Pro - Biotic Scrubber in their septic
tank and leach fields or drain fields have found that
the sludge and material that traditionally can back-up a system and
cause it to fail is actually eliminated, making the
system run more efficiently and prevent long-term failures and maintenance
costs. The equipment to perform this process can be integrated with existing water remediation systems to greatly increase their efficiency and lower the
cost of consumable materials.
