  1. BioGenerators for Organic waste treatment

  2. Waste Treatment Concerns • SHE (Safety, Health, Environment) Compliance • Odours/Overflows • Complaints • Costs • Out of Compliance Fines/Reputation • Pump out/Disposal charges • Clearing Line Blockages • Trap/tank/line Maintenance and repairs • Treatment costs/Utility Bills

  3. Organic Waste Treatment Options • Equipment : grease traps, septic tanks, DAF etc • Commodity Chemicals • Coagulants, Flocculants, Surfactants/Enzymes • Bacteria: Dry/Liquid • BioGenerators What’s the difference?

  4. What’s the difference? • Chemicals • Caustics/ strong acids/surfactants react with grease to form soluble compounds and generate heat to soften it and move it downstream • Potential Risks to personnel, environment and downstream blockages • Enzymes • Organic (protein) molecules that catalyse chemical breakdown of long chains to smaller ones. Each enzyme unique shape to work on one substrate eg Amylase for Starch breakdown to glucose. • Enzymes are NOT alive and so can not reproduce. Risk that long chains will reform downstream and cause blockages. No effect on Phosphates, Nitrates etc. • Bacteria • Living cells that reproduce by generating enzymes to break down the long chain waste molecules to shorter forms and then consume the shorter molecules and reduce them to water and CO2. Also consume any Phosphates, Nitrates, Ammonia in waste • No risk of downstream blockages, environmentally friendly • BioGenerators • Pre-grow tailored Bacteria in ideal conditions: nutrient, aeration, so huge colonies of fully active Bacteria are dosed automatically • Most effective and economical way to dose Bacteria

  5. Biological Products are NOT “all the same” • Bacteria/other constituents • Physical form: Solids, Liquids • Type and Number of Strains • Concentration/Activity/Shelf life • Nutrient content • Enzymes, surfactants and other chemicals in Blend • Cost /Price • Product Price vs Cost in use vs Performance • Application Equipment • Pumps/timers • BioGenerators: Grow tailored Bacteria in ideal conditions: nutrient, aeration, so huge colonies of fully active Bacteria are dosed automatically and ready to work immediately!

  6. BioGenerator Basics Tailored Nutrient Tailored Bacteria Incubator aeration process Highly active Tailored Bacteria

  7. BioGenerator-Bacteria • Most commonly Bacillus strains because they can be stored as stable, tough, long shelf life liquids, with Bacteria in Endospore form: • Subtillis, Thuringiensis, Licheniformis, Megaterium, Stearothermophilus, Polymyxa, Pumulis • Many other Bacteria can be used depending on nature of waste to be degraded including Pseudomonas Putida, Fluorescens, Stutzeri, ThioBacillus, LactoBacillus, Cellulomonasuda and more! • Bacteria produce: • Natural Surfactant (Surfactin) • Wide range of enzymes • Lipase: FOG • Amylase: Starches • Protease: Proteins • Cellulase: Paper/Vegetables • Ammonease/Reductase : Human/Animal wastes

  8. BioGenerator-Nutrient • For optimised performance, nutrient must sustain growth, activity and quality of the bacteria • Nutrient should include • Carbon source: Carbohydrates eg sugar • Nitrogen Source: Organic eg Amino acids/Protein • Phosphate/Potash/Micronutrients • pH regulation

  9. BioGenerator-Aeration • Bacillus strains are facultative Aerobes, so can cope with low/no oxygen, but grow FAR more effectively when correctly aerated. • Pseudomonas strains are obligate Aerobes and must be aerated or will die • O2 level should always be >2mg/litre • O2 consumption 3-20 ml/litre/min • O2 replenishment comes from surface in still solutions and from entrained bubbles in turbulent/circulated solutions

  10. BioGenerators-An innovative approach • Work WITH any existing treatment equipment • Effective • Tailored Bacteria (Active, Robust, long shelf life) • Variable nutrient regime • Aeration • Low Capital cost vs other WWT options • Low operational cost • Less Bio feed for given Bio activity • Low/No mains power, small/no pumps: can be driven by mains water pressure and battery powered controller • Robust, unique design ensures Minimal maintenance • Flexiblility • Waste type, flow rate, surges • Alignment to CIP/cleaning regime

  11. Effectiveness vs Cost in use Effectiveness/Performance High BioGenerator Liquid Bacteria Solid Bacteria Enzymes Surfactants Acids/Alkalis Pump outs/Cleaning Low High Low Cost in Use

  12. BioGenerators ALWAYS work... provided conditions allow... • pH • Temperature • Residence time • Food supply • Biocide additions/CIP programme but BioGenerator flexibility ensures quick recovery of activity even if there are temporary excursions

  13. BioGenerators • pH Range (for typical bacteria blend) • Ideal 6 to 9 • Will tolerate 5.5 to 10.5 but BioGenerator flexibility ensures quick recovery of activity even if there are temporary excursions

  14. BioGenerators • Temperature Range (for typical bacteria blend) • Ideal 15 to 35 °C • Will tolerate 5 to 50 °C but BioGenerator flexibility ensures quick recovery of activity even if there are temporary excursions

  15. BioGenerators • Residence Time • Exponential Growth in contact with waste • so “the longer the better” • 1 hour + BioGenerator major advantage over liquid bacteria products is that Incubation ensures huge quantities of highly active Bacteria are dosed every time Dormant products can be washed out before they are effective

  16. BioGenerators • Food Supply • Ideally Bacteria will always have food supply • Will tolerate up to 24 hours without food but BioGenerator provides its own nutrient supply, so Bacteria are constantly fed.

  17. BioGenerator • Biocides/CIP programme • By design, Biocides will kill “all” Bacteria including the “good” ones! • CIP programmes can be either very Caustic (high pH) or very Acidic (low pH) and will kill some or all BioGenerator Bacteria but BioGenerator will immediately re-colonise with huge population of the good Bacteria

  18. BioGenerators Standard System - Consists of equipment, Bacteria and nutrient. - Only service needed is water pressure in range 1.6 to 6 Bar. • Scalable • Very large systems can be treated with multiple standard units, or with bespoke larger designs (which may require mains power)

  19. BioGenerators • Typical Applications: • Grease Traps • Drain lines • Septic Tanks • Lift/pump stations • Waste Treatment plants Survey, design, troubleshooting support to ensure optimum application

  20. BioGenerators • Safe • Environmentally friendly • Innovative • Effective • Economical • Scalable
