For treatment of organic wastewater.
Sewage Treatment – BioFil-AE Industrial Effluent Treatment – BioFil-AA Hospital Waste Treatment – BioFil-AH Laboratory Waste Treatment – BioFil-ALBioFil is a proprietary waste treatment process developed jointly by Prof. Dr. Azni Idris and Universiti Putra Malaysia with Patent Application No: P19502143
Biofil technology is a proprietary system developed by the Waste Technology Centre, Universiti Putra Malaysia (UPM). It is a simple and innovative Biofilter process which is capable of treating high strength organic effluent at a minimum operating cost. It is a product of 8 years of research works carried out at UPM in particular related to treatment of the palm oil mill effluent. Full scale and pilot studies confirm the suitability of BioFil technology to treat large variety of effluent such as paper mill, poultry processing and palm oil mill. Resent application in treatment of sewage effluent has proven good results in achieving compliance to Standard A effluent discharge limit.The technology was innovated to provide less space, use less power and be more ‘environmental friendly’. There are two versions developed to treat specific waste streams, enabling plants to be built to individual industrial requirement and to whatever capacity requirement to cope with the anticipated level of effluent.
The aerobic BioFil (known as BioFil-AE) is capable of eliminating residual BOD in sewage and industrial effluent to below 10 mg/l.
The anaerobic BioFil is targeted to destroy high strength effluent exceeding 1000 mg/l to 150 000 mg/l of BOD.
BioFil technology is marketed and technically supported by Pakar Management Technology (M) Sdn.Bhd (PMT).
BioFil reactor contains a bed of suspended micro-organisms at the bottom of the reactor. The feed is maintained to keep the bacteria in suspension. Due to the upflow, very high biomas cencentration can be achieved in this lower section. Large suspended solids together with oil and grease emulsions in the effluent are trapped and degraded within this bed to a more solublesubstrate.
Inert media such as the “Special inert media” are provided in the bioreactor to provide a large surface area for bacteria attachment, exceeding 160 m²/m³. This attached biofilm greatly enhances reactor performance. The media used has been specifically designed to prevent plugging. Solids carry over from the reactor is often very low.
In anaerobic tank, biogas is collected from the head space of the reactor and can be used for electricity or steam generation. The biogas has high calorific value and generally has a methane content of 70% and the remainder being carbon dioxide.
BioFil system can take organic loading rate from as low as 5 kg COD/m³/day to over 20 kg COD/m³/day. Operating temperatures are generally between 27°c and 55°c. Some results have shown that more than 80% BOD5 removal is achievable in BioFil plants.
Industrial Applications: Many industries generate high strength effluent that can easily be treated uing high rate anaerobic treatment such as BioFil. Effluent with BOD5 greater than 100 mg/l are particularly suitable. Large industries with high organic effluent will find BioFil system to their great advantage. Substantial saving in energy costs can be obtained through on-site methane gas utilization.
BioFil is capable of treating wastewater from industries such as:
Due to the compact design, BioFil can be configured to suit any area or space constraint faced by industries or housing developers.
The inherent principle in design of bioreactors is the establishment of effective contact between the microorganism and the organic pollutants in the effluent. High rate systems are able to provide long solids residence time. BioFil reactors is a hybrid reactor that combines suspended growth and attaches growth systems in one unit. The design is able to exploit the best features of both technologies and overcomes their individual limitations.BioFil reactors are designed for complex municipal and industrial waste discharge. They rapidly becoming established as the most dependable, cost effective and stable process. In addition they are being used to revamp existing UASB and anaerobic digestor plants because of this enhanced stability. It also improves retention of the bacteria within the reactor volume. BioFil system offers some flexibility and robustness which makes it more attractive than conventional waste treatment system.
