Spare a thought for your Sewage Treatment Plant this Christmas
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.
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.
