SEWERAGE TREATMENT MODULES
"SBR" SECONDARY TREATMENT SYSTEMS
Description & Technical Specifications
First introduced in 1965 to accommodate single-family home applications. CromaFlow set the standard by incorporation the Sequencing Batch Reactor (SBR) mode of operation into a Pre-Engineered, modular design for flows under 500 gallons per day. Simple, user-friendly controls, in combination with dual submersible pumps, make this the complete model for homes with 3 bedrooms or less.

Description & Technical Specifications
A cousin to the smaller CA-5 model with larger aeration and clarifier compartments, the CA-12 and CA-15 are ideally suited for larger homes with more than 3 bedrooms. The Model CA-12 has maximum hydraulic capacity of 1,200 gallons per day, while the CA-15 is 1,500 gallons per day. Both units operate under standard SBR principles; fill, react, settle and discharge.
Applications range from residential, commercial, and recreational. Due to its unique modular design and simple controls, design engineers around the world specify the CA-12 and CA-15. Single discharge pump is standard, but may be engineered with duplex for redundancy. With higher organic loading obtainable and increased surge volume for peak flows, the CA-12 and CA-15 are the preferred choice for flows up to 1,500 GPD.

Description & Technical Specifications
Similar to the CA-12 and CA-15, the CA-25 operates most efficiently when used on residential applications ranging from 1,500 – 2,000 GPD. With a peak flow capacity of 2,500 GPD, the CA-25 may be applicable for small clustered development projects or in some small flow commercial/institutional flows.
Due to increased demand by design engineers for sludge management, CromaFlow developed the CA-30 with sludge wasting capabilities. This provides the operator a tool to optimize the activated sludge process. With redundancy in aeration and discharge, the CA-30 was the first complete fail-safe batch reactor. The CA-30 comes standard with built-in automation for responding to fluctuations in order to satisfy the oxygen requirement. The Alternating Discharge Pumps include Pump Failure Alarms to alert the owner to mechanical difficulty and unique floating decanter for optimal effluent low in Total Suspended Solids. This advanced design translates into reduced on-site time required by the plant operator.
The CA-30 is well suited for small shopping centers, office complexes, medical offices, schools, or small residential sub-divisions. Modular flexibility enables multiple units to be placed in parallel to accommodate higher flows for increased growth.
The Electrical Control Panel comes standard with a mechanical time clock, or optional Programmable Logic Controls (PLC).

Description & Technical Specifications
Both models have all features and benefits of the CA-30 but on a larger scale. Increased aeration and clarifier sections allow for higher organic and hydraulic loads. Man ways are easily accessible for routine operation and maintenance. All CromaFlow models have the ability to batch discharge clarified effluent with continued aeration and mixing all in the same tank. This unique design reduces the overall footprint required thereby creating otherwise useless real estate into a valuable commodity.

Description & Technical Specifications
CromaFlow 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.

AERATED PRE-EQUALIZATION SYSTEMS
HOW IT WORKS!
The tank is divided into two (2) main sections. The first section is the solids retention section, which is separated from the remaining section of the tank by a stainless steel mesh screen. The second section of the tank has the aeration pumps and the dual (redundant) discharge pumps. The pumps are ontrolled by a time clock or PLC which alternates power to the aeration pumps every two hours. The timer or PLC is adjustable for the amount of programmed ON and OFF time for pump operation. Hand-Off-Auto switches are provided for confirming the proper mechanical operation of the motors or for manually overriding the control circuit.

SLUDGE PROCESSING SYSTEMS
HOW IT WORKS!
Provided as an ancillary process primarily for sludge management, the CromaFlow Aerated Sludge Processing Systems greatly reduce Bio solids produced. This translates to annual savings and allows for a more efficient operating Wastewater Treatment System.
The Sludge Processing Tank (SPT) receives excess sludge produced from each treatment Module via manual ball valve located in-line with the return activated sludge pipe. The operator, at his discretion, will manipulate the valves to direct the excess sludge to the SPT during routine site visits.
When the sludge tank is full, sludge thickening is accomplished by manually turning off the aeration pump(s) allowing the tank to settle, and manually pumping the supernatant. After the tank has settled, a decant pump is provided to send the clear supernatant back to the head of the treatment works. The decant pump is located at the back of manway number two and manually controlled by a separate breaker as noted on the control panel enclosure door. The decant pump is suspended from an adjustable chain and should be set by the operator to a height slightly above the sludge/supernatant interface. A float switch mounted directly to the pump will disengage the decant pump as the water level drops.

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. CromaFlow 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.
