‘Out with the Old and in with the NuDisc’ at RSPB Headquarters, Bedfordshire

This month the RSPB have a shiny new KEE Wastewater Treatment Plant installed. This replacement KEE NuDisc® 20HR model and Twin Pump Station replaces their old G7 BioDisc Unit and Pump Station. The old plant was no longer suitable for their headquarters in Sandy due to the increasing staff numbers based on site and visitors attending the nature reserve.

Private Residential Golfing Community in New York State Selects KEE Process Managed Flow® Wastewater Treatment Process

Bristol Harbour is a private residential golfing community in the Western Finger Lakes of New York State, USA.

Having experienced ongoing problems with their existing wastewater treatment plant, the community approached KEE Process Limited’s North American partner, Waste Water Solutions International Inc., for help.

After suffering regular mechanical failures, deviations in effluent performance and high operating costs, the community recognised the need to upgrade their aeration plant. The new system would also need to cope with the planned expansion of the development and meet the State Law’s stringent treatment requirements.

The KEE Process Managed Flow® Process was selected because of its ability to continually produce high quality effluent and its low operator costs and maintenance. The system was also ideal for the site’s limited space and environmentally sensitive location.

To provide flexibility two streams were installed. The technology chosen included:

  • A balancing tank
  • KEE Process Managed Flow Rotating Biological Contactor (RBC) – Model DN-19-S
  • KEE Process Final Settlement Tank (Model ST9) with automatic pump assisted sludge return system and gravity sand filter with backwash capability.

This technology was designed and specified to provide for the current and future expansion of the community.

KEE design upgrade solution for Anglian Water using NuDisc® Technology

“ I had not personally worked with KEE before and I was impressed with their ingenuity and their unwavering commitment to deliver the upgrade at Brinkley on time and to a high standard. It is refreshing to work with a company that do not have a ‘fit and forget mentality’ and have a genuine passion for the service they give their customers. If ever I need some expert advice or another Waste Treatment Plant, I will not hesitate to contact KEE. ”  Gavin Pipe Anglian Water.

Background

KEE have been working with Anglian Water for over 30 years and were commissioned to design and install the original B16 Rotating Biological Contactor (RBC) at their Brinkley site back in 1983. Following mechanical failures well past the 30 year manufactured design life of the plant, Anglian Water knew 3 years on, that the site was in need of re-furbishing. Therefore they installed a temporary SAF Treatment Plant to be set up on site to treat the waste whilst they sourced and installed a replacement RBC.

Unfortunately the temporary SAF Plant kept ‘tripping out’ and proved unable to treat the effluent to the correct consent levels so Anglian Water had no option but to have the effluent removed from site manually using tankers.

The Challenge

At this point Gavin Pipe, Project Engineer for Anglian Water at Brinkley contacted KEE to arrange a site survey and quote for a new RBC replacement. Upon arriving on site, KEE noticed that Magnasol was being used to neutralise ammonia from the B16 discharge in order to achieve the required environmental consent levels. It was therefore clear that the old plant was not achieving today’s environmental standards without chemical intervention.



Anglian Water , Brinkley

The Solution

KEE recommended upgrading the old RBC with KEE’s latest NuDisc® Design Technology.  The proposed refurbishment included the following benefits:

  • NuDisc® technology delivering substrate and flow balancing
  • 20 years extended life of the plant for a third of the cost of a new plant
  • Elimination of chemical dosing resulting in a cost saving of £3,800 p.a
  • Reduction in the need for de-sludging and tankering from site, therefore minimising tankering costs, heavy traffic and noise through the residential estate
  • 3 day refurbishment installation program, providing huge savings in project management, human resource, and re-build costs when compared to a new installation
  • Chemical free solution, protecting the environment


Anglian Water, Brinkly

Anglian Water agreed to KEE’s proposal and the new RBC was installed on the 26th of September. The installation took the scheduled 3 days to complete and the Brinkley site is now back in full working order, benefiting from the very latest solutions in mechanical engineering and process technology.

KEE Triton® UPGRADES EXISTING ACTIVATED SLUDGE TREATMENT PLANT AERATION SYSTEM

The wastewater treatment plant at the village of Keith in Aberdeenshire treats municipal wastewater from the village and effluent from a famous branded Whisky Distillery nearby.

The overall process on site includes inlet works with a grit chamber and screen for municipal wastewater. After this preliminary treatment, the municipal wastewater stream is mixed with the Distillery effluent and is processed through the first-stage high-rate biofilter tower. The effluent from the biofilter tower is then processed through radial flow-scraped primary settlement tanks and the settled effluent is discharged into a two-stage activated sludge basin consisting of two tanks of 7.92m x 7.92m x 4.65m deep (water depth 3.65m). The mixed liquor from the activated sludge plant is discharged through to three radial flow-scraped final settlement tanks and the settled effluent is discharged to a watercourse. The settled sludge is returned (RAS) to the activated sludge basin with excess sent to sludge storage.  Finally, supernatant from the sludge storage tank is returned to the feed for the high rate filter tower.

The aeration system for the activated sludge basin consists of two surface-mounted aerators driven by a 20kW common-geared motor through a propshaft delivering approximately 30kg/hour of dissolved oxygen.

EXISTING AERATION SYSTEM – ONLY ONE SURFACE AERATOR OPERATING

The total BOD load to the plant from municipal and industrial sources is 570 kg/day and approximately 285kg of this is reduced through the high rate biofilter and the remaining 285kg/day is required to be treated through the activated sludge plant. The aeration tank capacity is 230m3 each and is normally operated at MLSS concentration of approximately 2000mg/l. One of the surface aerators in the existing aeration system had failed and a temporary venturi aeration system was installed to assist in oxygen supply.

KEE were requested to visit the site, analyse the situation and evaluate the process requirements to make a proposal to upgrade the aeration system. The factors to be taken into account included the need to upgrade the aeration system whilst the plant continued to operate (without decommissioning the plant) and to ensure that the new aeration device produced less than 60dB noise. KEE evaluated the existing process parameters and concluded that the plant could be operated at a higher MLSS concentration of up to 4000 mg/l at a substrate loading rate of 0.15g BOD/g MLSS.  The estimated dissolved oxygen demand on this basis would be approximately 33kg/hour.

KEE proposed to install four 5.6kW dual mode Triton processors to provide complete mixing of both the aeration basins and to supply up to 40kg/hour of dissolved oxygen. The Triton dual mode processor is an efficient aeration device which provides total (horizontal and vertical) mixing of the whole basin. It can be mounted from a wall or a bridge or can be supported from floats. The Triton can mix up to a depth of 10m and therefore is also ideal for upgrading existing aeration systems for total replacement or supplemental aeration. The Triton uses a low-power regenerative blower for air supply and a direct-coupled electric motor to generate a plume of fine bubble aeration which is able to penetrate through to the bottom of the tank. This  air/water mixer provides a long retention period for air bubbles and the resulting high efficiency oxygen transfer into the mixed liquor. By EPA definition the Triton is a fine bubble aerator.

KEE TRITON® AERATION IN OPERATION

The four Tritons were mounted from the side walls of the existing tanks and, once all the installation work was completed over two days, the electrical cabling was finalised. The blowers supplying air into the Triton were controlled through D.O. probes located in the aeration basin. Once all the electro mechanical work was complete the Tritons were switched on and the old aeration system switched off. The plant aeration system upgrade was achieved in less than one week’s time on site and without any downtime on the existing treatment process. There was no need to hire temporary plants to relieve activated sludge plant. Apart from large savings in capital and operating costs, the biggest benefit was that all the logistics and space problems associated with installing a temporary plant were avoided. The noise emitted by the new aeration system is much lower than specified and definitely lower than the previous system. The process performance of the plant has improved and the plant is able to meet its specified process objectives and has continued to do so for over twelve months.
