Whitewater ATU
 
 
Delta Environmental Products, Inc.


The Clear Choice for wastewater on-site disposal system is the Whitewater Aerobic Treatment Unit (ATU). The Whitewater ATU was tested under standard 40 of ANSI/NSF International and met and exceeded Class I requirements with an average effluent quality of 6 mg/L BOD5 and 7 mg/L TSS.

There is growing concern over ground water contamination, Delta's Whitewater Aerobic Treatment Unit can destroy up to 90 percent of virus, (99 percent with disinfection) and discharge nitrates less than 10 mg/l.

Delta's ATU is an effective and economical solution for the growing need of on-site disposal systems.
How does it work?



 
 
 
 
WHITEWATER HOME AEROBIC TREATMENT UNITS

   Delta Environmental Products, Inc., Whitewater Home Aerobic Treatment Units (ATU) are designed for on-site disposal of domestic wastewater. The unit can achieve tertiary quality effluent with total removal efficiencies of 96 to 97 percent of the impurities in the original wastewater. The unit will enhance any type of disposal method used in an on-site disposal system. Delta's Whitewater Aerobic Treatment Unit is used in direct surface discharge, spray irrigation, leaching chamber systems, conventional drain fields, or a combination of these. With the enhanced water quality, any one of the above disposal means will function better and longer. For poorer soils, smaller lots, high water tables, and recreational areas, on-site disposal can be achieved effectively and economically.

   Most septic tank failures are due to heavy BOD discharge into the soil which causes a biological growth to form thus clogging the soil significantly. High BOD reduction can only be achieved in advanced secondary processes. Delta Environmental Products, Inc., Whitewater Home ATU is an advanced secondary process. New types of disposal systems are being designed primarily to distribute the effluent evenly in the disposal field, but without considering the effluent quality these systems may not achieve the desired result.
