Water Recycling Techniques
Agricultural water recycling systems capture runoff water through collection ponds filtration systems. Modern treatment facilities process 500-1000 gallons per minute removing sediments nutrients pollutants through:
- Sediment settling tanks with automated sludge removal
- UV disinfection units eliminating harmful bacteria
- Reverse osmosis systems purifying water for reuse
- Nutrient recovery systems extracting phosphorus nitrogen
The treated water maintains EC levels between 0.5-1.5 dS/m making it suitable for irrigation. Storage systems include lined reservoirs with capacities ranging from 100,000-1,000,000 gallons equipped with float switches monitoring water levels.
Urban Agriculture and Vertical Farming
Urban agriculture transforms unused city spaces into productive growing environments through innovative vertical farming systems and controlled environment agriculture. These solutions maximize limited urban space while reducing transportation emissions from traditional food supply chains.
Indoor Growing Solutions
Indoor vertical farming systems integrate hydroponic or aeroponic technologies to produce crops in stacked layers. These systems include:
