In order to support sustainable development, BIOROCK has developed a sewage treatment plant that does not need electricity or chemicals to work. Making the choice to install a BIOROCK is a sound environmental decision.

Selecting a product that offers a sustainable solution to the problem of waste disposal is a key factor in protecting the local environment. The construction market is becoming increasingly aware of the need for environmentally sustainable solutions to issues such as sewage treatment and the disposal of effluent from off-mains systems. There is a clear shift towards responsible and sustainable products. BIOROCK sewage treatment systems are the acknowledged leader in this rapidly changing market.

Traditional VS BIOROCK

Electrically operated residential sewage treatment plants use power to aerate the raw liquid. There are numerous residential and commercial wastewater treatment techniques on the market:

RBC or “Rotating biological contractor” residential sewage treatment systems: A motor rotates half-submerged discs through the sewage inside the plant. Aerobic bacteria develop on the discs in the liquid; the aerobic phase of the treatment process occurs as the bacteria get oxygenated when the disc is out of the liquid.

SBR or “Sequencing Batch Reactor” residential wastewater treatment systems: This traditional technology involves air blowers or diffusors which “bubble” air through the sewage water to be treated. Some SBR residential wastewater treatment systems have media added to the raw liquid within the “biozone” chamber of the tank.  If this is the case the system is called a SAF for Submerged Aerated Filter.

Another technique involves pumps which spray the raw sewage on a “media” surface which is “colonized » by the necessary bacteria for the water treatment. The raw liquid gets aerated when it gets sprayed over the “media” surface. This technology requires electricity for the aerobic phase of the wastewater treatment process as pumps are required.

These electric wastewater treatment techniques are very high in commissioning, running costs (spare parts replacement) and energy consumption.

Our residential wastewater treatment system is from the “trickling filter” family type of product. These plants use various different filtration “media” types. This media is always essential for the effective treatment of domestic wastewater as it allows the necessary bacteria to grow and digest pollutants. Some manufacturers rely on organic media types such as coco fiber or nutshells. These organic media types need expensive maintenance and frequent replacement as they are bio-degradable and thus may break down over time.

BIOROCK Sewage treatment

At BIOROCK we have developed a special media material for our residential wastewater treatment technology. Our media is very highly resistant to degradation and remains extremely stable over the long term. It requires little maintenance and ensures unique purification results. This media is exclusively developed for BIOROCK and dedicated to foul wastewater treatment.

We have been developing and improving our media continuously during the past 25 years.

BIOROCK ensure that a minimum of 98% of materials used in manufacture are recyclable so installers, maintenance engineers and owners can be confident that the environment is protected throughout the life of a BIOROCK product. The BIOROCK media is ecological, locally produced and 100% recyclable.

Our experience in the industry and the satisfaction of our international dealers and local Certified Contractors networks are proof of this long term experience. BIOROCK offers a unique, ecological and economical wastewater treatment solution compared to the traditional techniques described above.

BIOROCK complies with British Standards, the Building Regulations and E.A. Pollution Prevention Guidelines.
