Water & Wastewater Treatment

BioRotor® – The Right Solution

Napier-Reid (N-R), with over 60 years of experience in the water and

wastewater treatment industry and over 3,000 projects worldwide, provides

innovative custom solutions for our customers. Rotating Biological Contactor

(RBC) technology has withstood the test of time and proven that it is one of

the most effective waste water treatment systems available. With over 80

years of use and thousands of systems installed, the RBC technology has

proven effective when it comes to efficiency and simplicity when treating

wastewater.

N-R’s strong shafts translate to many years of trouble free operation and

little to no maintenance cost for the shaft. Our BioRotor® system is compact

and does not require lagoons, outside holding tanks, or security fences. A

key advantage is that our system is quiet and odorless and the enclosure can

be built to blend into any surrounding.

BioRotor® is an extremely efficient secondary biological wastewater treatment system that

is also well suited for advanced wastewater treatment. It utilizes aerobic fixed film

technology to reduce organic matter (BOD5), total suspended solid (TSS), ammonia and

phosphorous (P). RBC systems were first introduced in Europe in the 1960’s.

A typical BioRotor® system consists of hundreds of thin circular plastic disks, collectively

known as media, mounted on a horizontal shaft. Corrugated plastic with a thickness of

0.060” (1.5mm) is used to maintain high structural integrity while maximizing the

biologically active surface area which promotes the growth of the many types of bacteria.

Around 40% of the disk’s surface area is submerged in a tank that contains the wastewater.

Continuously driven by a gear motor, the media rotates slowly at about 2 rpm.

Bacteria which is naturally present in human waste attach and multiply on the rotating

media forming a thin layer of biomass

The rotation carries the biomass and a thin layer of wastewater into the air facilitating the

absorption of oxygen. This aerated layer of bacteria is then re-submerged into the water

where it metabolizes organic matter from the wastewater producing the required effluent

quality. The RBC design provides for optimum aeration eliminating the need for complex

and expensive aerators. As the film starts to grow, excess biomass is removed by shearing

forces by the disks’ rotation in a process called sloughing. The rotating action of the disks

also helps keep the solids in suspension.

BioRotor® is designed with multiple baffles to create a wider biodiversity. The variety of

bacteria, coupled with optimum oxygen absorption, translates to a consistently high

effluent quality, a shorter retention time, and low sludge generation. Thus our system

requires a much smaller footprint when compared to a conventional sewage treatment

system with similar capacity. BioRotor® units can be arranged in various configurations to

meet the flow and organic load requirements and to provide secondary or advanced levels

of treatment e.g.: Ultra violet disinfection, denitrification, filtration etc.

Advantages of BioRotor®

1) Proven Process: BioRotor® is capable of treating a variety of flows without compromising

effluent quality – no minimum inflow of sewage is required. The system is also able to

handle overloading for short periods of time. Superior process design insures that

retention time and head loss through the system is reduced. All of our systems exhibit low

sludge production and consistent process results and process control. The simplicity in

operation means that no sludge recycling and less lab testing for process control is

required.

2) Easy & Immediate Start-up: the BioRotor® system is designed to be a complete

wastewater treatment plant. Start-up can be handled with minimal technical experience

because the systems are preassembled. The main task is lowering the system into the

foundation support - a process that can be completed in as little as 30 minutes.

3) Low operating & Maintenance Costs: Operating costs are very low since no chemicals

need to be added to the process and minimal skill is required to operate the plant. In fact,

frequent supervision is not required since our systems are automated and can include an

alarm in the event the system stops working. Our system requires very little power and the

only tasks during maintenance are lubrication of the drive and bearings and bi-annual

removal of sludge.

4) Inoffensive & Unobtrusive: Our BioRotor® systems can be installed near public places

since they are quiet and produce no odour. It can be housed within any structure of the

client’s choice. NR can provide fiberglass covers that not only protect the BioRotor® from

the outside elements and trespassers but also help maintain a low profile that is

aesthetically pleasing in any environment (e.g.: golf course, hotels, within a community

etc.). Our systems can operate year round under all conditions.

5) Flexibility & Sustainability: BioRotor® is able to expand with the population being served,

because additional systems can be installed in parallel to increase the total capacity. This is

an essential benefit for municipalities and developments expecting to grow over time.

6) Environmentally Friendly: BioRotor® is energy efficient and does not incorporate toxic

chemicals that can harm the environment. The effluent produced is clean and safe enough

to discharge directly to surface watercourses or subsurface tile beds.

Shaft

Made of 1.5 mm thick high density polyethylene for structural strength. Large flow channels to allow sloughing of excess biomass. Corrugated design to increase the effective surface area. Ultraviolet protection provided by the incorporation of a carbon black stabilizer. Moulded holes that spread the load evenly in the corrugated media. Mounted with stainless steel or galvanized steel pipes fixed at three points for effective

mechanical support.

Outstanding structural design. Capable of withstanding, with a safety factor of at least two, the worst case scenario of having the disks full of wet biomass and the tank completely empty.

Structurally designed for minimal deflection. Designed with low stress level for long-term service life.

Explosion proof design. Robust in design and built with high quality components. High efficiency planetary reducers built and rated in accordance with current

international gear manufacturing standards. Powerful Compact gear-reducer designed for high torque. Synthetic-oil lubrication for years of smooth and quiet operation. Shrink disc mounting on RBC shaft transmits torque with a high safety factor. BioRotor® is mounted on huge spherical self aligning roller bearings with a life expectancy

of over 50 years.
