A biological fixed film treatment technology, Bioclere reduces biochemical oxygen demand (BOD5) and total suspended solids (TSS) concentrations to levels that meet or exceed National Sanitation Foundation (NSF) and Environmental Protection Agency (EPA) standards. Bioclere’s treatment capabilities also include the conversion and reduction of nitrogen making it ideal for nutrient sensitive sites. Aquapoint tertiary treatment products can be added to the process chain to enhance nitrogen, phosphorus and turbidity reduction and to disinfect the waste stream. A 21,000 gpd Bioclere treatment system serving a housing development. Effluent requirements are <30 mg/l BOD, <30 mg/l TSS and <10 mg/l Total Nitrogen. A tertiary denitrifying ANOX Biological Reactor and UV Disinfection provide the final stages of treatment before effluent is distributed to a soil absorption field. 1 BIOCLERE FEATURES Treatment capacities from 200 to 100,000 gpd: A wide range of Bioclere filter sizes are available. The modular units can be placed in parallel to accommodate large flows or in series to achieve high levels of treatment. Broad range of applications: Bioclere installations include single family residences, residential clusters, subdivisions, shopping malls, nursing homes, schools, restaurants, gas stations, golf courses, hotels, medical facilities and municipalities. Performance based engineered systems: Each system is sized by Aquapoint Engineers based on the influent hydraulic and organic characteristics of your site. Specification of these variables is essential in designing a Bioclere treatment system that will meet your permitted effluent requirements. A Design Criteria form is included in this package for this purpose. Fixed film treatment process: Naturally occurring microorganisms attach themselves to the highly permeable, randomly packed media and create a biological filter. The wastewater is trickled through the filter allowing organic matter to be absorbed by the microorganisms. The filter is self-purging, self-regulating and requires minimal maintenance. Bioclere utilizes several different types of media varying in size, shape, aperture size and surface area. Large media is generally used for roughing applications and small media used for more extensive treatment and polishing. Hufo Media Flocor Media Organic and hydraulic fluctuation: Generally Bioclere installations do not require flow equalization prior to treatment. The ability of the biological fixed film to self-regulate over daily and seasonal variations in hydraulic and organic loading, variations in temperature, pH and process inhibitors is widely acknowledged. Bioclere 16/12-350 has been tested and proven by EPA’s Environmental Technology Verification (ETV) program and is NSF standard 40 certified. NSF test results are included in this package on page (7) and ETV results can be viewed at http://www.epa.gov/etv/pdfs/vrvs/09_vs_bioclere.pdf 2 Fully enclosed sturdy construction: Bioclere is constructed of insulated UV resistant fiberglass, PVC and stainless steel. The systems are sealed and insulated making Bioclere ideal for extreme climate applications. Unaffected by short term power failures: Because the treatment process occurs above the gravity flow line, electrical outages do not interrupt flow. Re-circulation of treated water within the system dilutes septic tank effluent and minimizes the impact of short-term power failures on effluent quality. Easy Retrofit: Bioclere can be easily installed between the septic tank and the distribution/disposal system to upgrade treatment for existing facilities. Low operating costs are characteristic of the trickling filter heritage. The simplicity of the design and the stability of the fixed film process minimizes energy consumption and operation & maintenance costs associated with wastewater treatment. Minimal operation & maintenance requirements: Routine maintenance procedures consist of cleaning the spray distribution nozzles, and ensuring proper functionality of the axial fan and pumps. Aquapoint provides complete technical manuals with all of our treatment systems. The manuals include troubleshooting information, maintenance checklists and other tools designed to make operations & maintenance easy and effective. Easy installation: Because Bioclere comes as a pre-assembled modular system, units can be easily installed with minimal field work. Aquapoint provides onsite consultation for every Bioclere Bioclere dosing array spray nozzle maintenance installation. State of the art control panels: Bioclere control panels are built in NEMA 4X watertight enclosures allowing for indoor or outdoor installation. All control panels utilize audio and visual alarms and can incorporate remote dialers designed to call the operator in the event of an alarm condition. Analog or programmable logic control (PLC) panels are available on all systems. Remote monitoring capability: Bioclere controls can be designed with Aquapoint’s Aqua Alert remote wireless telemetry package. Aqua Alert provides the operator with the ability to monitor system conditions and manipulate system functions directly from an internet accessible computer. Bioclere PLC control panel with Aqua Alert telemetry package 3 BIOCLERE TREATMENT PROCESS Wastewater flows from the septic or primary settling tank into a baffled chamber inside the Bioclere’s clarifier. The baffled chamber prevents short circuiting of wastewater through the system. Alternating dosing pumps are automatically activated by timers and periodically dose the media filter with wastewater from the clarifier. Above the media filter a dosing array ensures uniform distribution of the wastewater over the media surface. Oxygen is distributed throughout the filter by a fan that draws external air into the Bioclere. In the trickling filter the organic material in the wastewater is reduced by a population of microorganisms that attach themselves to the media and form a biological slime layer known as biomass. Treatment is accomplished in the outer layer of the biomass by aerobic microorganisms. As the microorganisms multiply and the biological film thickens, diffused oxygen and organic substrate are consumed before the wastewater penetrates the full depth of the film. Consequently, the biomass develops aerobic, anoxic and anaerobic zones. As the microorganisms that are in contact with the plastic media become starved for oxygen and organic carbon that is consumed by the surface layer, they lose their ability to cling to the media. The trickling wastewater washes the biomass off of the media and a new biological film begins to form. This process of losing the biomass is called “sloughing”. The rate of sloughing is primarily a function of organic and hydraulic loading on the filter. This natural process does not compromise treatment and allows the media bed to be self-purging, self-regulating and maintenance free. The sloughing biomass is washed through the trickling filter and settles to the bottom of the clarifier as secondary sludge. Bioclere’s re-circulation system periodically pumps the secondary sludge back to the septic tank where it is stored and eventually removed. This physical process is essentially the same for the reduction of BOD5 and nitrification (conversion of ammonia nitrogen to nitrate nitrogen). Standard single Bioclere installation: 4 NITROGEN REDUCTION (NITRIFICATION/DENITRIFICATION) Removing ammonia from wastewater is a well-established and quantifiable biological process. Nitrogen exists in the influent waste stream primarily in the form of organic nitrogen and ammonia nitrogen (Total Kejldahl Nitrogen or TKN). The principle part of the organic nitrogen is mineralized to ammonia nitrogen by bacterial activity in the septic tank. Therefore, ammonia nitrogen is commonly regarded as the starting point in the nitrogen reduction process. Nitrification is the conversion of ammonia (NH3) nitrogen to nitrate (NO3) nitrogen. This biological process is accomplished by Aerobic Autotrophs, Nitrosomonas and Nitrobacter bacteria in the presence of dissolved oxygen. Bioclere effluent ammonia concentrations of 1 mg/l to 3 mg/l are reliably achieved. Successful nitrification is accomplished with a healthy microorganism population and an environment where pH, alkalinity, temperature, organic loading and oxygen supply are relatively stable. In a Bioclere system; the pH is buffered by the carbonate system associated with wastewater; the temperature remains relatively constant because Bioclere provides an enclosed and insulated environment and the biomass generates heat; the organic loading is relatively consistent because treated wastewater is recycled through the septic tank and the Bioclere; and the fan provides an adequate supply of oxygen. Denitrification is the conversion of nitrate (NO3) nitrogen, to nitrite (NO2) nitrogen and then to nitrogen gas which is released into the atmosphere. This is a biological process performed by Facultative Heterotrophic bacteria in the presence of a soluble carbon source and anoxic conditions (dissolved oxygen = < 0.3 mg/l). Denitrification occurs by several different means and through process control adjustments. In the Bioclere trickling filter, diffused oxygen is used up by the aerobic outer portion of the biomass and anoxic conditions are created within the biological film. This allows for significant nitrogen removal in the Bioclere via simultaneous nitrification and denitrification. Denitrification is also achieved by re-circulating nitrified wastewater from the Bioclere back to the septic tank where there is an anoxic zone and sufficient carbon in the influent waste stream to denitrify. This process has achieved total nitrogen reductions up to 80 percent. TERTIARY DENITRIFICATION Nitrogen removal can be enhanced further with an Aquapoint ANOX Biological Reactor or a denitrifying sand filter following Bioclere treatment. Aquapoint employs tertiary denitrification when effluent total nitrogen concentrations of <10 mg/l are required for sites with elevated influent TKN concentrations. These denitrification methods have proven effective and are recognized as viable processes by the EPA. PHOSPHORUS REDUCTION Bioclere treatment systems achieve phosphorus reduction by dosing the waste stream with coagulants such as metal salts, typically aluminum or iron. This type of phosphorus removal is simple and is the most commonly used method in the United States. It consists of adding metal salts that react with phosphates in the wastewater to form insoluble precipitates. The precipitates settle to the bottom of the treatment chamber reducing the phosphorus concentrations in the wastewater. Coagulant dosing rates are based on the stoichiometric metal salt to phosphorous ratio dictated by the concentration of phosphorus in the daily wastewater flow. The efficiency of phosphorus removal is simply related to the coagulant dose provided that alkalinity is present in sufficient quantities. The precipitated sludge can be processed in the same manner as typical settled sludge. This type of phosphorus reduction can effectively achieve 80-95 percent total phosphorus removal and effluent concentrations of <1 mg/l. Greater reduction in total phosphorus can be achieved by incorporating a physical barrier filter such as a sand filter, disc filter or a membrane. 5 66 SUMMARY OF BIOCLERE ANALYTICAL RESULTS TESTED TO STANDARD 40 BY THE NATIONAL SANITATION FOUNDATION NOTES: The median is the point where half of the values are greater and half are less The interquartile range is the range of values about the median between the upper and lower 25% of all values. Testing of the Aquapoint Bioclere model 16/12-350 was conducted under the provisions of ANSI/NSF Standard 40 for Residential Wastewater Treatment Systems (January 1999 revisions). ANSI/NSF Standard 40 was developed by the NSF Joint Committee on Wastewater Technology. The performance evaluation was conducted at the Buzzard’s Bay Project Test Center located on the Otis Air National Guard Base in Massachusetts using residential wastewater diverted from the base. The evaluation started with two weeks of dosing without sampling to allow for plant start-up. Once a treatment biomass was established, NSF sampled for sixteen weeks at design flow, performed seven weeks of stress testing and then sampled for three more weeks at designed flow. Sampling began in late summer and continued into the winter, covering a range of operating temperatures. Over the course of the evaluation, the average effluent CBOD5 was 11 mg/l, ranging between 4 and 26 mg/l. The average effluent TSS was 5 mg/l, ranging between <2 and 15 mg/l. Effluent pH ranged from 6.1 to 8.1 within the required range of 6.0 to 9.0. The plant also met the requirements for noise levels (less than 60 dbA at a distance of 20 feet), color, threshold odor, oil film and foam. 7 GENERAL INFORMATION The septic tank or primary settling tank performs the primary treatment stage of the Bioclere process. Sizing of the primary tank should take into consideration the effect of re-circulation on detention time. Bioclere units are constructed with the effluent pipe 180 degrees opposite the influent pipe. The only routine service procedures required are pumping of the primary tank, Bioclere pump and fan maintenance, and infrequent cleaning of the dosing array nozzles. Tertiary treatment equipment added to the process chain will require additional service. In most states a licensed wastewater treatment plant operator is required to perform this maintenance. The pre-assembled, self-contained Bioclere units are easily installed into new or existing facilities. Aquapoint’ s operations team will supply a Bioclere lifting harness and will provide onsite consultation for every Bioclere installation. Concrete pads with mounting eyes are supplied by the contractor and set at the appropriate elevations before the Bioclere is set on the pad and chained to the mounting eyes. The Bioclere is leveled by adjusting turnbuckles on the chains. Interconnecting piping between the septic tank, Biocleres and additional treatment or disposal equipment is the responsibility of the contractor. Multiple units can be installed in a few hours with adequate site preparation. The Bioclere is commissioned by filling the clarifier with fresh water so that the dosing and re-circulation systems can be tested. Once the Bioclere is commissioned it is ready to receive wastewater flow and will take four to eight weeks to establish a healthy biomass for treatment.
