G&O Bioreactor
Full treatment of both black and grey water
The G&O Bioreactor represents the next generation of Biological Sewage Plants and is able to handle all kinds of waste water from any vessel and oil platform. The plant is an “Aerated Submerged Fixed Film Unit" which operates by use of the “Matrix Technology". The G&O Bioreactor system provides an excellent growth environment for our bacteria media. The tank is fitted with a rigid PVC matrix, with the exception of water freeboard above the matrix and approximately one foot of water filled between the Matrix and the bottom of the tank.
By this we obtain a 125-150 times larger internal surface at where the bacteria media can adhere compared to any traditional Active Sludge Plant/tank. In this manner we secure any operator full operational freedom all around the globe with a system that exceeds any known or expected future environmental demands!
The system operates exclusivly with the use of UV for sterilisation.
- Highly efficient system for treatment of Black & Grey water delivered by Gravity or Vacuum. This includes complete degradation of organic matters including fat & grease.
- Problem-free operation. All controls, parts and man holes are placed on one side according to demand. Easy maintenance as there are no moving parts inside the bioreactor.
- Low maintenance requirements. Due to few moving parts and easy access to all moving parts. All sludge are redirected to the plant making the need for desludging very limited (depending on actual load).
- Tolerates organic and hydraulic shock/peak loadings Easy and tolerant to operate. Resistant to periods without waste water inlet.
- Total environmental friendly. Approved with UV light sterilization - no need for adding of chemicals.
- Tested with excellent results. Test results are far better than any known or expected demands.
- Type approved by flag state to MEPC 159 (55) and also Wheelmark approved.
- Available in standard and customized designs.
Compact design in all sizes
The “Small footprint" by use of the “Matrix technology" provides the possibility of a very compact design which is relevant where space is very limited. Furthermore the plant has a limited weight and can be designed/delivered as a retrofit plant and in different sizes.
Delivered in Mild Coated Steel, Stainless Steel
Only the best epoxy coatings is used with officially approved specifications from Makers.
Can be delivered in EEX versions
Several Plants delivered to the highest demands.
High quality components
Only well-tested pumps, compressors, UV-units and control panels are used on G&O Bioreactors.

Introduction
The G&O Bioreactor represents the next generation of Biological Sewage Plants and is able to handle grey and black water from any Ship or Offshore construction. The plant is an “Aerated Submerged Fixed Film Unit" which operates by use of the “Matrix Technology". The G&O Bioreactor system provides an excellent growth environment for our bacteria media. The tank is fitted with a rigid PP/PVC matrix. By this we obtain a 125 times larger internal surface where the bacteria media can adhere compared to any traditional Active Sludge Plant/tank. In this manner we secure any operator full operational freedom all around the globe with a system that exceeds any known or expected future environmental demands.
Principle of Operation
Black (and grey if required) water is directed to the Inlet Mixing Tank either by gravity or by a Vacuumarator Pump. The Inlet Mixing Tank is designed to even-out peak loadings to ensure a steady liquid flow through the plant and thus optimizing the biological cleaning process in the Bioreactor tank. From the Inlet Mixing Tank, the waste water is transferred to the Bioreactor Tank by a Macerating Pump mixing grey and black water and cutting up all solids. The mixed waste water passes the vertically installed Matrix in the Bioreactor Tank driven by compressed air fed into the process by air diffusers in the bottom part of the tank. The compressed air further supplies oxygen and in turn enhances the biological process in the Bioreactor Tank. The treated water flows from the Bioreactor Tank to the Settling Tank by gravity. In the Settling Tank the treated water passes an installed matrix prior to being transferred to the Clean Water Tank. By exposure to an advanced UV light filter all remaining Thermo Tolerant Coli Bacteria are eradicated prior to entering the Clean Water Tank. Organic and mineral sludge deposits in the Settling Tank are at regular intervals transferred to the Bioreactor Tank for further treatment. Liquid level in both the Inlet Mixing Tank and the Clean Water Tank is controlled by 2 level switches: A high level switch starting a transfer pump and low level switch stopping the pump. The plant is designed for fully automatic operation but can also be operated manually from the control cabinet. The plant is designed for easy access for all maintenance purposes.
