The sanitary regiment of water basins in a wastewater discharge zone is defined by intensity and flow of natural self-purification processes. The threshold concentration limit for titanium coagulant was established as a result of model studies.
The study of titanium coagulant impact on a sensory characteristic of water was conduct for finding threshold limit for the reagent.
Data obtained as a result of the study could be characterized as very high degree of bacterial and viral decontamination.
Sanitary safety studies of the titanium coagulant and secondary pollution risk estimation
Studies shows that: Specific sensibility difference was not found; titanium coagulant doesn’t have conjunctiva irritation effect; titanium coagulant is attributed as low-hazard and noncumulative substances; titanium coagulant does not cause any functional changes in central nervous system; titanium coagulant has no sensitizing or allergenic impact: etc.
Studies show that titanium coagulant has no toxic impact on embryos, has no toxic impact on gonads, and has no mutagen affect.
Titanium coagulant application for water purification under 50 mg/l (5 times greater than maximal working dose of 10 mg/l determined from previous test) is safe for potable water by impurities content.
There were conducted health studies to determine conditions under which titanium coagulant is applicable in modern processes of water purification and chemical treatment for swimming pools. This study was conducted by The Saint-Petersburg State Medical Academy named after I.I.Mechnikov and was carried out on working swimming pool water treatment equipment. Definite sorption ability accompanied with low toxicity (IV class of hazardous materials) allow the titanium coagulant to be recommended for use in swimming-pools water treatment systems.
