As objects of study used samples of salted 
sand coast Kazakhdarya drained bottom of the 
Aral Sea. Samples were taken at a depth of 0–
5 sm. 
As an additive-fixer was used solution

of calcium chloride at the rate of receipt of 
predetermined amounts of the activeproduct

having a high value of specific surface area 
andrespectively the adsorption capacitance for 
waste water treatment is not used as a finished 
product, and at the time the diluted solution of 
sodium silicate and calcium chloride. Thus as 
well as the first case, distinguishing the 
product is a colloidal dispersion degree at the 
stage transition sol-gel. The essence of the 
method of cleaning colored water is formation 
of silicate sorption calcium systems at the 
transition “sol-gel”. Purification of dyed 
wastewater is performed as follows: to a 
colored waste water containing dyes are 
administered dilute solutions of calcium 
chloride, sodium silicate and aluminum 
sulphate and mixed. Occurs flocculation and 
coagulation slurry. Maximum lighting solution 
comes practically instantly, so that after 2–5 
minutes of slurry possible to separate.
