Module 3 Growing more fish and plants for human consumption and enjoyment Review: Module 2 - Beds, Filters What are the filter types? •Ebb and Flow •Flow through •River bed •Deep gravel •Strawberry tower •NFT Nutrient Film Technique •DWC Deep water culture •Raft method What does the bell siphon do? •Aerate water in gravel beds •Aid biofiltration What else do Grow beds do? •Grow plants •Collect solids •Host earthworms •Convert Ammonia Cost? Develop safe reliable system using one pump (cid:57) Utilize gravity (cid:57) Understand head, hp to watts to kwh to cost (cid:57) GFIC required Understanding dissolved oxygen (cid:57) Venturi (cid:57) Sheeting (cid:57) Use Flow form aeration where ever possible Understanding filtration (cid:57) Gravel beds for trapping solids and also for additional biofiltration (cid:57) Ebb and flow – Build simple bell siphon prototype (cid:57) Flow through beds (cid:57) NFT- Nutrient film technique (cid:57) Low cost main biofilter Plants are for (cid:57) Nitrate removal (cid:57) Ammonia removal (cid:57) CO / carbonic acid production 2 Meet plant fertilizer needs First Prototype (cid:57) Grow plants in soil if not aquatic (cid:57) Soil based plants - vermicast, cocopeat (cid:57) Dependant on capillary action of potting soil – we have ideal materials N 2 Denitrification NO 2 NO Nitrification 3 NH 3 Ion Balance H+ NH + 4 Gas Stripping TAN Mineralization BOD Bacteria Solids Alkalinity Addition BOD Reduction CO 2 Dissolved Refractory Management Inert Aeration Solids O 2 Solids Removal Modified version from Ronald F. Malone, Dept of Civil Engineering, Louisiana State University Full time security Bed types for plant types Soil based Plants get soil Water based plants get gravel Floating Plants get to Float Conventional Aquaponics Grow Medium: Perlite, rock wool, coir, peat, synthetic Tank Solids Hydroponic Biofilter Sump Culture Removal Subsystem Settled solids Suspended solids Plants Grown in soil less medium Raft method--DWC NFT $.09 start plugs (4 peso) Compressed Bark Biofiltration Bacci tower installed
