NOISE AND ODORS CONTROLLED
Attractive tank modules with locked maintenance hatchways enable Cromaglass Systems to be installed without odors or noise associated with other types of open sewage treatment plants, when operated properly. Tanks can be installed below ground close to buildings being served saving unneeded pipe and/or pump expense.

  BY-PASS NOT POSSIBLE
Cromaglass Systems are designed to make bypass and intertank contamination impossible. When operated properly, no bio-mass can transfer from one section to another except through the programmed pumping system. All sludge collected in the settling chamber is automatically returned to the aeration section for further aeration and breakdown. This results in low sludge accumulation. Most residual sludge that collects is made up of biological ash and insoluble particles. Sludge can also be wasted to a Sludge Processing Tank.



  MAXIMUM OPERATIONAL FLEXIBILITY PROVIDED BY PLC CONTROLS
State-of-the-Art PLC controls will respond to the inputs from level sensors and probes in the tanks. The PLC automatically adjusts treatment parameters in response to changes sensed in the influent. It can store a permanent record of all operational functions, which provides information on each function of each cycle for whatever time reference desired. Such information can indicate if service or maintenance is needed, and the operator can then schedule it before a failure occurs.

  STRONG, LIGHTWEIGHT, and REUSABLE
Corrosion-proof vessel construction of strong, lightweight fiberglass. Covers and locking hatches are also of fiberglass. Tanks are constructed to withstand pressure involved when installed at acceptable depths below ground. Being light in weight means expensive cranes are not required, saving installation costs. Because Cromaglass Systems are completely integrated, compact and transportable, they can be reused, relocated and/or resold when changing circumstances warrant.
