What to do when the bubble has burst
2010, the Cobb County (Ga.) Water System (CCWS) lost 8% of its work force,
representing 38% of total employee tenure. Responding to both local and
national impacts, CCWS developed several countermeasures that were varied but

activities and effluent uses require different degrees of filtration. For
example, reusing wastewater at a paper mill requires special considerations
because of the high quality of water needed for paper production. Read about a
pilot-study on using membrane bioreactor and reverse osmosis technologies to
increase the mill’s production capacity and reduce its discharge fees.
brackish wastewater from coalbed methane extraction for discharge requires
careful attention. Find out how one coalbed methane facility is treating 35,000
barrels of water per day, using an efficient combination of advanced treatment
technologies that consist of filtration, ion exchange, and reverse osmosis.
These processes remove coal fines, iron, and dissolved salts from wastewater,
with an overall water recovery of more than 99%.
when it comes to municipal wastewater treatment, meeting effluent requirements
sometimes requires filtration. After 20 years of operating dual media filters
with increasing operations and maintenance needs, a San Francisco utility
sought the best configuration for the media to decrease the backwash reject
water ratio, attain reliable compliance with discharge requirements, and
increase filtration time.
