Ammonia-contaminated water treatment system of fish farms
Ammonia-contaminated water treatment system of fish farms
The concentration of non-ionic ammonia (NH3) in the water of fish breeding ponds should always be less than 0.5 mg per liter; Because ammonia is a toxic substance for raising fish and other aquatic animals. Other toxic substances for fish and other organisms should also be removed from fish breeding ponds. These materials can include insecticides, pesticides and other chemicals; Therefore, water purification in the fish farming industry is very necessary to remove these toxic materials. The most appropriate method to reduce ammonium and other toxic substances in fish breeding ponds is biofilter. PGA company is capable of making such biofilters in different dimensions.
Desalination with reverse osmosis method
Water purification and desalination system with reverse osmosis method
The process of reverse osmosis or water sweetening is a method to separate impurities from water. In this method, the separation factor is mechanical pressure. Currently, the reverse osmosis process plays a very important role in water purification.
Grey water treatment and recovery system
