Why Choose BIOROCK
BIOROCK sewage treatment plants will save you up to and over €700 per year and over 0.5 tonnes CO2 emissions every year for standard sized plants when compared to the current market leading sewage treatment plants. Larger sewage treatment plants will save you much more!
Because BIOROCK sewage treatment plants work in a unique way they offer many advantages over all other sewage treatment systems. BIOROCK sewage treatment plants have the smallest carbon footprint of any sewage system. Typical single house sewage treatment plants produce 0.55 Tonnes of Carbon Dioxide emissions every year. The BIOROCK produces NONE.
The following tables shows a comparison between the BIOROCK system and
other market leading systems. As can be seen, the benefits are huge
to installing the BIOROCK system.
| 3 Stage Treatment Plants | Aeration Plants | BIOROCK Plant | |
|---|---|---|---|
| Electricity Bills | YES | YES | NO |
| Emptying Interval | 3-12 months | 2-5 years | 5+ years |
| Wet Concrete for Installation | YES | SOME | YES |
| Noisy System | YES | YES | NO |
| Handle Large Range of Household Cleaners | NO | NO | YES |
| Effluent Quality (BOD:SS:NH3) | 20:30:20 | 20:30:20 | 04:03:03 |
| Expensive Parts | YES | YES | NO |
| Works During Power Failure | NO | NO | YES |
| Handles Variable Loadings/td> | SOME | NO | YES |
| Handles Seasonal Loading with no Reduction in Effluent Quality | NO | NO | YES |
| Large Carbon Footprint | YES | YES | NO |
| Expensive Maintenance Cost | YES | YES | NO |
| Mandatory European Certification | SOME | SOME | YES |
The superior treatment efficieny of the BIOROCK system is another compelling reason to purchase the system over all others. The effluent from a sewage treatment unit is measured in terms of the Biological Oxygen Demand (BOD), the Suspended Solids (SS) and the Ammonia (NH3). It is expressed in the form BOD:SS:NH3 and is measured in mg/L. The normal standard for effluent quality from sewage treatment units is 20:30:20 (BOD:SS:NH3). To understand these figures, septic tank effluent is around 120:180:80 and distilled water is 0:0:0, so obviously, the lower the figures the betterthe quality.
The BIOROCK sewage treatment unit has been tested to EN12566-3 2005 and the EN12566-7 2006 standard in the EU testing facility PIA in Aachen, Germany. The table below summarises the results from the extensive 38 weeks independent EN testing on the BIOROCK sewage treatment unit. Essentially the independent testing showed that the BIOROCK sewage treatment unit produces a very high quality secondary effluent. Given normal use, BIOROCK sewage treatment units greatly exceeded the normal standard of 20mg/l BOD and 30mg/l SS by four times.EN 12566-3 2005 Summary of the Test Results from Aachen
When tested at The EN Test Centre, the BIOROCK consistently produced an effluent quality (in mg/L) of (BOD:SS:NH3) < 4:3:3
| Parameter | Results - including shock and overloading tests | Average |
|---|---|---|
| BOD | 100% less than 20 mg/l | 4 mg/l |
| Suspended solids | 100% less than 15 mg/l | 3 mg/l |
| Ammonia | 100% less than 20 mg/l | 3 mg/l |
The BIOROCK stayed within the 20:30:20 standard 100% of the time.
Full EN test results are available on request. BEFORE you order a rival sewage treatment system, ask the manufacturer for their EN 12566-3 2005 actual test results and compare them with the BIOROCK.
