Spare a thought for your
Sewage Treatment Plant this Christmas

With the festive season upon us, guests arriving and the celebrations in full swing, please do keep in mind what you and any visitors are pouring or flushing down your drainage system into your Sewage Treatment Plant.

Do’s

  • Follow manufacturers’ recommended doses for your water type when using household cleaning products. Soft water requires far less detergent concentration than hard water.
  • Try to use cleaning products little and often so your treatment plant is not overloaded.
  • Use liquids (not powders) in washing machines and dishwashers. Powders re-coagulate into clumps and can cause blockages.
  • Try to spread your clothes washing throughout the week.
  • Stick to the same washing, dishwasher and other cleaning products as the bacteria will work more efficiently with products it is used to treating.
  • Think before you put anything down the sink, toilet or drains.
  • Desludge your plant when required. Click HERE to view our one page KEE EXPERT guide on proficient desludging and how regularly your unit should be desludged.
  • Ensure only toilet paper is flushed down the toilet and used in normal quantities.
  • Leave your plant switched on while you are away or on holiday. Switching off your plant can cause damage to the motor and moving parts as well as kill the biomass.
  • Compost all your organic food waste or use your local council bio-degradable waste recycling service (where applicable) to dispose of organic waste. Do not flush organic waste down the sink or drain.

Don’ts

  • Don’t put sanitary towels, tampons, cotton wool or cotton wool buds, incontinence pads or any baby, cleaning or facial wipes down the toilet.
  • Don’t flush rubber products or other non-biodegradable products down the toilet.
  • Don’t pour fat, grease or cooking oil down the sink or drains. Fats suffocate the bacteria and inhibit the biological process. Everyday products such as milk, wine or beer increase the organic load and should also not be disposed of through the wastewater system.
  • Don’t use neat disinfectant or bleach. KEE recommends that these products are only used at the minimum concentration possible, as they can restrict the biomass growth within the plant.
  • Don’t tip medicine, mouth wash or any chemicals such as photographic fluid or garden products (e.g. Insecticides, weed killers and fungicides) down the drains as they will damage the biological treatment process.
  • Don’t pour DIY products (e.g. paint, thinners, turpentine and white spirit etc.) or car fluids such as engine oil, anti-freeze, brake fluid etc. down the drains.
  • Don’t allow rainwater, groundwater or large volumes of water (such as those from a swimming pool or Jacuzzi) into the plant. Chlorine kills the bacteria and the excessive water will increase the flow rate through the plant, not allowing sufficient treatment time.
  • Don’t fit a waste disposal unit under your kitchen sink. Disposing of organic matter through the treatment system increases the organic load, creating bacterial overgrowth which will inhibit the treatment process. Only use a waste disposal unit if your plant is specifically designed to accept higher organic loads.

Don’t want to pay for a new treatment plant – why not refurbish your old one?

KEE Process and KEE Services Limited have been commissioned to refurbish and update countless old and tired treatment plants. The example shown below is of a unit located in a small Welsh Village. The ageing plant was proving unreliable and not performing efficiently so KEE designed and built a KEE NuDisc® to replace and update the old treatment plant. 

Refurbishment of old BioDisc

KEE’s upgrade solution was – KEE NuDisc® Technology.

Often the structural housing of a wastewater plant can be re-used, meaning the internal components are replaced with brand new factory built KEE systems, incorporating the latest concepts in mechanical, structural and process engineering.

Refurbishments of this kind extend the life of the plant by another 20 years, drastically reducing the overall lifetime cost when compared to installing a brand new plant.

KEE’s Service technicians complete a full refurbishment suitability survey to assess the compatibility of each plant for an upgrade. This is applicable to all manufacturer makes of wastewater treatment plants and not just those designed, and produced by KEE. Water Authority sites have proved popular with refurbishments, reducing Water Authority spending and providing brand new refurbished treatment plants which are fully compliant to the relevant Authority specification.

Refurbishments remove the costly civil work elements associated with complete plant replacement.

Utilising current process equipment can often increase the treatment capabilities of the existing system, therefore making the refurbished plant fit-for-purpose for increased flows and loads, a problem which often occurs with old systems as more influent is added to it over their working life.

Following refurbishment KEE can continue to service, maintain and monitor the condition of the plant to keep it in good working order and performing efficiently.

Why Refurbish?

  • Minimises waste by only replacing the parts of the plant that need replacing.
  • Greatly reduces the volume and complexity of site works.
  • Less noise and general disturbance on site.
  • Minimises plant ‘downtime’. A refurbishment is generally quicker to complete than a new installation.
  • Incorporates the latest process design features and efficiencies such as KEE’s ‘managed flow’ system to protect the environment and meet wastewater consents and legislation.
  • Reduce or eliminate the need to find an alternative location for a new plant.
  • Extends plant lifespan by 20 years, at a fraction of the total cost of a new plant.

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.

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.

The KEE Process Managed Flow RBC Model DN-19-S and a KEE Process Final Settlement Tank Model ST9 with automatic pump assisted sludge return system and gravity sand filter with backwash capability installed at the Bristol Harbour private residential golfing community in the Western Finger Lakes of New York State, USA.

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
10 KEE RBCs

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:
