Cromaglass has long been a leader offering modular, SBR technology with flows under 15,000 gallons per day. By incorporation all the features and benefits of its predecessors, the CA-100, CA-120, and CA-150 models set the standard for secondary and tertiary treatment at flows up to 200,000 GPD.
With the incorporation of automated controls, hydraulic overloads are virtually elimimated. The aeration process is self-adjustion as needed, to satisfy increased liquid volume and organic loading.
Multiple units may be placed in parallel for larger flow systems.
Multiple tank systems enable the operator to maintain efficient treatment at peak flows as well as during low flow periods.
Primary uses include large residential sub-divisions, restaurants, retail shopping centers, schools, country clubs, hotels, resorts, airports, and many more.
The unique two tank construction allows for easy installation at almost any site. The strong lightweight tanks are typically installed end to end, but may be installed side by side if space restrictions require.

Typical Cycle
FILL;
AERATION
Flow enters the Solids Retention Section (A) that 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.
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 venture aspirators that receive air through pipe intake from the atmosphere.
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 over-flow weirs back into the main Aeration Section. Transfer ceases and Clarifier ( C ) is isolated – solids separation occurs under quiescent conditions.
DISCHARGE
After settling, effluent is pumped out of the Clarifier ( C ) for discharge. Return sludge is pumped 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.
