Micro-Irrigation for Greenhouse Crops
Water Filtration Systems
Filtration equipment ensures that organic and inorganic particles such as sand, algae, or silt bigger than the smallest inlet or outlet hole in the system are removed, protecting the irrigation system from clogging (Figure 17.8). If chemicals or acids must be added for water treatment, be sure to determine if the materials should be injected before or after any filtration equipment. Some chemicals will react with the materials from which the filters are manufactured. Water-soluble fertilizers are typically injected after the filters and must be in solution, and chemicals must be tested prior to injection into the irrigation system.
