How our commercial Sewage Treatment System works:
All of our treatment systems are Sequencing Batch Reactors (SBR) which is a treatment process widely used in many modern municipal treatment plants.
The SBR process is a form of Activated sludge treatment and employs a five stage cycle, fill, react, settle, empty and rest. See our video on Youtube http://www.youtube.com/watch?v=k6ybKlywwpQ
Effluent is taken from the first compartment, where incoming effluent is stored, and fills the reactor.
All of our systems employ compressed air to transfer the effluent. Once the reactor is full to a pre-set level the next phase begins
Aeration takes place in the biological reactor. Air is pumped periodically through fixed membrane plates which defuse the air evenly in the liquid. The rising bubbles create an activated sludge process in the chamber. This process is controlled from the control unit to match the design criteria for the particular system.
Once the aeration cycle is completed the wastewater is allowed to rest for a period allowing sludge to settle out. Excess sludge is then returned from the base of the reactor to the first compartment using a pneumatically operated lifting device.
The treated effluent is then discharged to the percolation area or for tertiary treatment.
The process then enters a rest period.
The overall cycle typically lasts 7 hours
Because the SBR process treats the effluent in batches it is particularly suited to sites where there are wide variations in flow.
The size of the pre-chamber can be designed; using additional buffer tanks if necessary, to cater for peak flows and spread the load to the reactor evenly over a period of time.
If the flow to the treatment system drops as during holidays or shut downs, the system will react accordingly, treating effluent as it arises while periodically aerating the aerating to ensure the activated sludge remains effective.
Design of Systems
We will design each system bases on the particular loading applicable to the site. Each compartment will be designed to suit site conditions. Pre-chambers will be sized to cater for peak flows and required de-sludging frequency.
Dosing systems and pump chambers can be incorporated as determined by the treatment standards and disposal method required.
All of our treatment systems are modular and can easily be expanded if the effluent load increases.
All of our treatment systems use precast reinforced concrete tanks which we deliver and install minimising civil works.
We provide full maintenance contracts if required. See link to our maintenance page https://www.irelandwastewater.ie/maintenance/
Commercial Sewage Treatment Tanks
The “Euro-Bio” treatment system uses a type of activated sludge (suspended growth) process, known as an SBR (sequencing batch reactor) process. This is identical to the systems used in some large Local Authority treatment works, but on a smaller scale.
Commercial Rainwater Harvesting
Mains water is expensive and likely to get more expensive in the future. You can reduce your water consumption dramatically by implementing our Rain Water Harvesting Systems instead of your mains water for a variety of uses.
Commercial Pump Chambers
We supply a range of pumping systems for domestic, small communities and commercial waste water applications. Our pumping stations are designed using durable pre-cast concrete sumps and overflow tanks with retention times tailored to suit your criteria.
Our Eurobio system is the only unit in Ireland offering a Holiday mode , Which is ideal for Christmas breaks, Midterms & Summer holidays.
This unique feature allows the controller to continuously monitor the level in the system and will only start a cycle when its required, this allows the school to save money that could be utilised for other more important items in their annual budget.
