FILL: AERATION
Flow enters the solids Retention Section (A) which is separated by non-corrosive screen. Inorganic solids are retained behind the screen. Organic solids are broken by turbulence created with mixed liquor being forced through screen by submersible aeration pumps. This eliminates the need for mechanical comminution.
DENITRIFICATION (OPTIONAL)
Provided by an anoxic period during the regular treatment cycle. Cromaglass units create anoxic conditions by closing the air intakes of the aeration pumps with electric valves. This stops aeration, but the system continues mixing.
TRANSFER / SETTLE
Treated mixed liquor is transferred by pumping to the Clarification Section (C). The transfer period overfills the Clarifier with the excess spilling through overflow weirs back into the main Aeration Section. Transfer ceases and Clarifier (C) is isolated - solids separation occurs under quiescent conditions.
AERATION
Liquid and small organic solids pass through the screen into the continuing Aeration section (B). Air and mixing are provided by submersible pumps with venturi aspirators that receive air through pipe intake from the atmosphere.
DISCHARGE
After settling, effluent is pumped out of the Clarifier (C) for discharge. Sludge is returned from the bottom of the Clarifier (C) back into the main Aeration Section (B) using a submersible pump, or sludge can be wasted to a Sludge Processing Tank.

Since 1965, Cromaglass' modular design enables effective treatment of wastewater flows ranging from 500 GPD (1.9 M3) to 200,000 GPD (56.8 cubic meters).
Cromaglass Corporation manufactures a variety of wastewater treatment systems which are designed as Sequencing Batch Reactor (SBR) systems.

Some of the advantages of the Cromaglass system are:
High efficiency
Low operation costs
Noise and odor free operation
Modular underground installation
Experience
All systems have been thoroughly tested and proven through 35 years and thousands of installations worldwide.
