Cromaglass Wastewater Treatment
The Cromaglass Corporation produces wastewater treatment systems called Sequencing Batch Reactors (SBRs). These tanks are made of light fiberglass and can be installed alone or in batches.
The Cromaglass Corporation has been manufacturing septic systems since 1965. It is based in Williamsport, PA, but operates in far-off locations such as Jamaica and Iraq. Cromaglass waste systems are used by a variety of independent contractors, and the company suggests that more than 10,000 are currently in operation. Many of these are large systems designed for municipal governments or corporations. Cromaglass employs 25 people and has an income of about US $5 million a year.
The Sequencing Batch Reactor
The SBR has three compartments, each of which increases the purity of waste water. The first section filters out large particles. The second mixes the water with bacteria and oxygen to degrade organic matter. The third compartment allows the water to sit so that remaining waste can settle to the bottom. Some of the fluid is circulated back through the tank to increase overall purity.
Some SBRs are remotely monitored by computers. Cromaglass detects malfunctions in the tanks and sends representatives out to inspect and repair them. Others are equipped with alarms.
Cromaglass wastewater treatment systems are available for volumes of wastewater anywhere between 500 and 200,000 gallons per day.
Cromaglass offers a special version of its product specifically geared towards eliminating nitrogen from wastewater. This option involves adding an extra stage of water treatment in which the middle chamber is deprived of oxygen as turbulence continues.
The company also sells supplementary tanks that can be easily attached to the basic Sequencing Batch Reactors (SBR's). These include storage tanks for high volumes of sludge and chlorination tanks for disinfection.
