Batching It
by Kate O'Brien
Builders and developers of small
communities not serviced by
municipal sewerage systems can
provide efficient and pollution-free
wastewater treatment for a reasonable
cost, with this batch wastewatertreatment
system. Chromaglass systems
are available in seven standard sizes,
from 500 to 12,000 treated gallons per
day. How it works: Free oxygen is
introduced, and aerobic
microorganisms clean and clear
wastewater of 85 to 95 percent of its
suspended solids. Batch treatment,
much like the process used in
municipal waste-treatment centers, is
used. The treatment cycles are timecontrolled
and a preset volume of
treated effluent is pressure-discharged,
allowing for peak surges and requiring
less retention time. As a result, drain
fields do not get clogged, or polluted.
