Lead is found in environment in natural form; however, human activities have disturbed natural cycle of lead. The lead contained in petrol and burning it produces lead salts in environment. The lead discharged from car exhausts arrived into peripheral environment. The larger particles of lead penetrate into water or soil and the smaller particles move into atmosphere; a part of those particles enter land through rain. This cycle of lead production is much stronger and powerful than natural cycle of lead and therefore, lead pollution in environment increases.
Lead accumulates inside the body of living organisms in water and soil and causes their intoxication. Removing lead from drinking water and sewer or waste water is highly important due to high toxicity of this substance.
Lead is one of the four dangerous metals for human body. It enters into body by eating (65%), drinking (20%) and air (15%).
Lead could enter into drinking water through pipes corrosion and this becomes more acute when the water is acidic. Therefore, it is of high importance to regulate the water PH in drinking water purification system. Based on studies, lead not only has no benefits for human body, but also it is very harmful for health.
Lead might cause various undesirable symptoms and problems to health:
Due to harmful impacts of lead on human body, using a safe and effective method for removing lead from drinking water has become more important than ever. Therefore, the R&D Department of Pala Gostar Sanat Ab Company has studied different methods of lead removal across the world and by selecting the most suitable methods with high output, has transferred the technology of removing lead per case into the country. Therefore, the first system of lead removal from drinking water in Iran is already implemented in Golestan Province for Rural Water and Sewage Co. of Golestan. The system has already covered 2000 population in minimum. The advantages of this system include:
Pala Gostar Sanat Ab Company, with the aim of specialized and professional activities in the area of design and manufacturing of new water and sewage purification system as well as achieving technical knowledge of designing the omission pollutants from environment in water and sewage area, tries to offer the best approaches with most inexpensive prices to officials in order to supply people especially deprived people of the country with inexpensive technologic methods of water purification.
