Treatment plants of water containing ammonia, hydrogen sulfide, carbon dioxide and iron Fe Depending on natural conditions of ground waters formation, they may contain surplus ammonia, hydrogen sulfide, carbon dioxide and iron Fe at the same time or in various combinations. Water treatment process at the suggested installation involves primarily its aeration-degassing procession at the aeration-degassing column where regular aeration of carbon dioxide, hydrogen sulfide and ammonia in quantities depending on initial pH of processed water. Oxidation of divalent iron Fe into ferric iron with further hydrolysis and hydrated oxide of iron indissolvable in water is effected in degassing-aeration column as well. At the same time hydrogen sulfide is partially oxidized to colloidal sulfur well coagulated by hydrated oxide of iron. Further on the water flows to double layer filter where water is posttretaed of ammonia and its derivatives, coagulated sulfur and hydrate oxide of iron. Water posttreatment on the filters is effected by mechanical filtration and exchange-sorption qualities of specially chosen filtering medium. Last stage of water treatment is disinfection effected at the special disinfection unit of the plant. In accordance with the customers requirements disinfection unit of hydrochloride or ozone, or UV-rays. Suggested installation provides water
preparation in conformity with Sanitary inspection regulation 1.4.1074-01
(Potable water), they are quite compact, ecologically safe. According
to customer's requirements treatment station could be operated either
manually or automatically. At the present moment apart from existing
standard technologies and modular installations, Inecs, Ltd offers
to its customers design, production, commissioning of separate installations
and water treatment plants of high and medium capacity (from 25
to 1000 and more m3/day) with the usage of natural waters
of complex composition, containing exceeding concentrations of chemical
and biological elements including highly toxic compounds and bacteritic-virus
contaminations. Drawing1. Principal technological scheme of
ammonia, hydrogen sulfide, iron Fe and carbon dioxide removal of
ground waters: 1 - ground water feed for treatment; 2
- degassing-aeration column; 3 - compressed air
feed; 4 - holding tank of degassed water; 5
- water feed to filter; 6 - double layer granular
filter; 7 - crushed filtering medium of ash-cindery
wastes of thermal power plant and large boiler plants operating
on carbon; 8 - granular medium of natural material
- clinoptylolite; 9 - water disinfection by chlorine
or ozone, or UV-rays; 10 - disk mixer; 11
- water feed to treated water tank and to the customer; 12
- air blowers unit; 13 - export pump; 14
- check expansion valve Installation of potable water preparation "VOS-6" of 6 m3/day capacity
Installation of potable water preparation of 6 m3/day capacity is aimed for deironing of ground water extracted from well, and for its treatment to Sanitary inspections standards 2.1.4.1074-01 "Potable water". Installation is developed by Inecs, Ltd in Sochi on the base of modern scientific and technical achievements and is fully produced at factory which increases the level of industrialization of erection works and enables prompt bringing into service. Installation comprises two independent lines that makes it possible to effect preventive repairs and maintenance without interfering into treatment process.
