Congruent phosphate control is the boiler water internal treatment most widely used in many industries, such as pulp and paper, chemical, petrochemical and in many applications for the power generation. The great benefit lays on the ability of this program to absorb small quantities of contaminants, such as acid, caustic, liquors and others. The big challenge is to maintain the Na:PO4 ratio inside the established limits. If the boiler chemistry is controlled within these limits, the risks of deposition and many forms of corrosion are practically neglected. Due to contaminations and steam production variation, manual systems produce irregular results of "in box time" on the control charts. The first generations of automated systems brought excellent results, with a high percentage of in box time. OnGuard iController, the controller presented in this paper, raised significantly this control, providing much more reliable results to the boiler water treatment. The system description shows the equipment benefits and its capabilities. Along with the description, two case histories are described and show precise conclusions for this controller. Source

An estimated 40,000 pre-school children are poisoned with lead and other heavy metals in the city of Shymkent, Southern Kazakhstan, with its still operating lead smelter. The maximum soil lead concentration measured in the residential area was 24,000 mg/kg. The investigation effort continued in Shymkent, including mapping the whole town for metals in soil, in air and in children's blood. Special studies showed that the lead was found to be in an extremely high bioavailable state. These results were presented to all levels in the national and regional governments, and in 2007 the President of Kazakhstan said that this was one of the greatest environmental problems in Kazakhstan, and needed to be solved. After extensive risk assessment and modeling, the overall area considered for remediation in Shymkent was set as the area within a 400 mg/kg contour for lead in surface soil. ITFCEH's proposals for remediation include removing soil from contact, removing exposure pathway, reducing concentrations, and reducing bioavailability or uptake in the human body. Source
