Over the years, KEE Process Limited has produced and delivered numerous Wastewater Treatment Plant projects in Northern Ireland and Ireland, using local M & E contractors.

In the Republic of Ireland and Northern Ireland many of KEE’s projects have been using local M & E contractors who offer total supply and installation packages to clients, with fully comprehensive after sales support. Some of these projects include plant built for the following sites:

1.   Large Hotel, Co. Wicklow.

The hotel already had a wastewater treatment plant but they decided to build a new 40-bedroom lodge on site and therefore needed a plant to treat all the existing flows plus the flow from the planned expansion. The main requirements of the client were:

The final effluent required Total Nitrogen and Phosphorus reduction and needed to consistently comply with the onerous discharge license of BOD < 20 mg/l, SS < 30 mg/l, COD < 80 mg/l, NH4-N < 20 mg/l, NO3-N (Nitrate Nitrogen) < 5 mg/l, Phosphate as PO4 < 12 mg/l, FOG (fat, oil and grease) < 20 mg/l and Detergent (MSAS) < 1 mg/l.

The plant was to have low operational and maintenance costs.

The plant supplier was to be able to provide complete service to include planned preventative and emergency maintenance, process and operation maintenance and effluent sampling.

The KEE’s proposal included supply, delivery, installation and commissioning of a 60m3 primary settlement tank, Module DC16 Rotating Biological Contactor and ST6 hopper bottom GRP final settlement tank. All this equipment was factory built and delivered to site ready for installation on concrete slabs.

This plant was installed and commissioned in 2003. It has operated extremely well mechanically and has delivered excellent process performance since start-up. The total electricity costs for the plant is less than EUR1,000 per annum.

2.   Golf Club, Co. Cork

This was a design and build turnkey contract and KEE who were process partners in the project. The discharge license was direct to the watercourse and specified a BOD < 20 mg/l, SS < 30 mg/l, NH4-N < 20 mg/l & Phosphate as P < 2 mg/l.

KEE supplied their compact single piece NuDisc® Model 1200.

3.   Golf Club, Co. Dublin

During the refurbishment of the clubhouse, on-site sewage treatment plant and disposal systems were required. The discharge license specified a BOD < 20 mg/l, SS < 30 mg/l & NH4-N < 10 mg/l, NO3-N (Nitrate Nitrogen) < 15 mg/l, Phosphate as PO4 < 5 mg/l and FOG (fat, oil and grease) < 10 mg/l.

KEE Process Ltd designed the process and supplied and installed a single-piece compact packaged plant NuDisc® F13N with inbuilt de-nitrification stage and phosphate removal stage.

This contract also included the design and installation of an inlet pumping station and a sub-surface percolation area.

4.   County Council, Ireland

This was an installation for a municipal treatment works for a Southern Ireland County Council for 1000 PE. The flow to the works are combined with surface water and municipal wastewater with a discharge license for BOD < 20 mg/l and SS < 30 mg/l.

KEE supplied their packaged modular treatment system and the contractor led the contract for installation and commissioning.

KEE collaborate with Northern Ireland Water on a £5m investment to construct one of the largest RBC sites in Europe.

KEE’s expertise in design, manufacture, installation, servicing maintenance and operation of equipment for all types of wastewater treatment plants is backed by over 60 years of experience and over 350,000 installations worldwide.

Background

KEE have been working with Northern Ireland Water (NIW) for over 15 years, providing treatment plants for many of their water infrastructure projects. The most recent collaboration involved KEE Group working on a new £5 million wastewater system for 5,800 people at Keady, Co Armagh. The new Keady Wastewater Treatment Works was to deliver improvements in process efficiency, discharge quality and increase the capacity of the plant to encompass the neighbouring population in Armagh.

KEE technical experts worked closely with NIW consultants throughout the term of the project, providing the following:

  • Support and guidance in selecting the correct treatment process and technology
  • Detailed 3D plant designs and specifications
  • Manufacture and supply of wastewater treatment equipment
  • On-site training for NIW Services Staff, to ensure optimum plant process performance and extended life
  • On-going site maintenance and back up support

The Challenge

The new plant was to meet the following requirements:

  • To be constructed within the existing site of the old plant
  • Achieve current and future NI Environment Agency discharge standards and EU regulations.
  • Provide additional capacity to meet the future needs of the growing local population

The Solution

The consistent performance of KEE’s RBC technology installed in Derrylin back in 2010 gave Northern Ireland Water the confidence to proceed with the Keady project.

The new plant was installed in the Autumn of 2012 and consisted of a Tertiary Slow Gravity Sand filter and 10 RBCs (Rotating Biological Contactors).

Each RBC was housed in a precast concrete chamber with GRP top covers to protect the equipment from the weather and enable easy access for maintenance. The upgrade in technology achieved NIW’s current and future consent and capacity requirements and delivered the following additional benefits:

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.
