Specialists in Domestic & Industrial Wastewater Treatment

Congratulations to Adrian, Antonio & Luis who successfully completed their Slinger / Banksman course at KEE Group Head Office on the 29th of June 2018.

It is imperative that a qualified ‘Slinger Banksman’ is in charge to direct and oversee the operations.

When KEE require the help of an external company to lift our bigger units on to the back of low loaders ,a 40 tonne or 50 tonne crane is required. When this takes place, the Slinger Banksman has to ensure that the lifting plan for the unit is carried out as specified. Any error in the lifting process can cause uneven pressure loads on to parts of the equipment so it is imperative that a qualified ‘Slinger Banksman’ is in charge to direct and oversee the operation. The Slinger Banksman guides the Crane Operator to where they need to be positioned whilst ensuring no other people come into the lifting area when a lift is taking place. Each lift involves positioning the lifting slings in the correct place and being in constant contact with the Crane Operator to ensure the lift is safe to complete.

We all at KEE look forward to seeing Adrian, Antonio and Luis out in the yard putting their training in to practice!

KEE REVITALISE OXIDATION DITCHES WITH THEIR DUAL MODE TRITON AERATOR/MIXER PROCESSOR

The KEE patented Dual Mode Processor called the Triton Aerator/Mixer is new technology that overcomes the previous limitations of oxidation ditch technology and can be used to revitalise existing oxidation ditches and technology.

Oxidation ditch technology is one of the oldest ways of treating wastewater. Whilst it enables wastewater to be treated to a high standard, including nitrification and denitrification, it does have significant limitations.

The process requires aerated and mixed liquor to continuously move through the aeration ditch. Brush rotors and disc rotors aerate and mix the liquor but, because they can only maintain the necessary fluid velocity of 0.3 – 0.4 m/s in a shallow depth of no more than 2m, the footprint area of the oxidation ditch is extremely large.

The KEE Triton Aerator and Mixer Aerator is an energy efficient, dual mode (aeration and mixing) process aerator that is capable of nitrification and denitrification all in one unit.  With two propellers and a regenerative blower, it is able to operate either as an anoxic mixer with the blower turned off, or a very efficient aerator/mixer with the blower turned on.

With its two mixing propellers, the Triton is able to achieve significant velocities in depths of up to 10m. This means the oxidation ditch basin can now be built up to 10m deep, therefore significantly reducing the footprint area.

The Triton Aerator/Mixer’s primary and secondary propellers inject air bubbles (defined by the Environmental Protection Agency as “fine bubble”) into a high velocity stream (plume) below the surface of the water and provide flow linkage mixing in multiple unit arrangements.

The Triton can also be used to revitalise existing oxidation ditch systems with failing brushes or disc rotors.  If the rotors have totally failed, the Triton can replace them.

CASE STUDY

Franklin’s plant has two oxidation ditch systems operating in parallel, each of which treats 4536 m³/day, with influent BOD of 185 mg/l and TSS of 90 mg/l.  The Oxidation Ditch Wastewater Treatment Plant at Franklin was failing to meet the consent of 15mg/l BOD and 23 mg/l TSS. Because the rotors required daily lubrication, maintaining them was a time consuming and costly exercise. So when the rotors fractured and failed four years ago, the decision was made to upgrade the plant by replacing the brush rotors with the Triton Aerator/Mixer.

Triton Aerators at the Franklin Wastewater treatment Plant help to produce
an effluent BOD of 2 to 3mg/l.

During the upgrade each ditch was fitted with four Triton each rated 18.6 kW.  This represents a maximum of just over 2 kWh of electrical energy per kg of BOD or 0.4 kWh/m³ flow.

The final effluent quality from the refurbished oxidation ditch is testimony to the excellence of the Triton. The result of the upgrade was final effluent with BOD of between 2 and 3 mg/l and TSS well below 15 mg/l. Independent velocity measurements at extremities are well above the minimum 0.3 m/sec, therefore guaranteeing that no solids deposit would develop in the basin.  At the same time, maintenance requirements have been substantially reduced to a simple lubrication task once every six months.

The Triton with its two mixing propellers is able to to achieve significant velocities in depths of up to 10m. This means the oxidation ditch basin can now be built up to 10m deep, therefore significantly reducing the footprint area.

Alternatively, if the rotors are still in good working order but the plant is failing to meet treatment objectives due to lack of dissolved oxygen and/or mixing of the oxidation ditch aerators, Triton can be used in conjunction with the rotors to improve dissolved oxygen levels and mixing.

KEE NuTech TERTIARY FILTERS

Biological Tertiary Filter Units for BOD, Suspended Solids, Ammoniacal and or Total Nitrogen reduction.

1.4 RENDER-modified

KEE have introduced a new range of tertiary filter units to their wastewater technology called KEE NuTech Tertiary Filters.

The new range of KEE NuTech Tertiary Filter units are a multistage biological – physical system and operates with minimal maintenance and does not require electrical power for its operation, except for specific circumstances. The tertiary filter polishes the final effluent from the final settlement stage of a treatment plant and the polished effluent can be discharged through a UV light disinfection system to make it suitable for irrigation use.

The media is contained in easy to handle bags and these bags are arranged to optimise the breakdown of the organic components of wastewater by alternating aerobic and anoxic stages.  The aerobic layers of media are aerated through natural ventilation using ventilation stacks and vent pipes or can be low pressure, low power, fan assisted through forced ventilation.

The bio-degradation capability of the tertiary filter eliminates the need to backwash the filter on a regular basis.  The tertiary filter media therefore provides the physical separation of the fine solids and the environment for the natural bio-degradation of these retained solids.

KEE EnviroSAF – FINE BUBBLE AERATION with easy access membrane diffusers, meaning no treatment down-time.

KEE offer another revolutionary fixed film technology using compressed air. Traditionally, SAF systems with structured media have been offered with fine bubble membrane diffusers, with the drawback that access to diffusers was difficult. Until now it has been necessary to remove media and empty the reactor tank of wastewater to access the fine bubble membrane diffusers.

KEE have patented new technology, making it possible to access the fine bubble membrane diffusers without the need of emptying the SAF tank, or removal of the media. Whilst one set of fine bubble membrane diffusers is being maintained the rest of the SAF plant can continue to function and treat the wastewater. This negates the need to empty or hire a temporary plant while maintenance is being carried out.

Cut-away view of the KEE EnviroSAF

KEE have installed 2500 PE SAF Systems in Scandinavia using this new EnviroSAF technology and also have built plants for UK Water plc..

The KEE EnviroSAF uses patented structured media which has a profile in its shape to induce velocity and pressure gradients in the air/water mixture flowing through the media. This concept enhances mixing and is responsible for keeping the biomass film on the media active and aerobic. KEE have offered SAF Systems for many years and have built100’s of containerised mobile plants for Work and Army Camps, where the systems were designed to be above ground as they needed to be mobile. Access to diffusers was therefore easy.

KEE have also installed SAF Systems in Northern Ireland where the final effluent quality achieved is extremely high, with BOD less than 4mg/litre, ammoniacal nitrogen less than 2mg/litre, phosphorus less than 4mg/litre and suspended solids less than 10mg/litre. The EnviroSAF technology offers all the process stability of fixed film reactors, but with the added advantage of using fine bubble diffused air, patented structured PVC media and the ease of access for maintenance of diffusers without the need to remove the media and emptying the EnviroSAF tank.

The KEE Group of Companies is committed to providing a customised approach to domestic, commercial and industrial wastewater treatment applications. With over 60 years’ experience in the development, design and manufacture of equipment, KEE has installed more than 350,000 solutions worldwide.
