Amur Gas Processing Plant now has modern water and sewage treatment facilities

It is clean and without harmful contaminations. Amur GPP now has the water and sewage treatment facilities, two very important modern units. The designs of these facilities were created in Saint Petersburg. Angelika Pavlova is going to tell us about the way water passes before it gets to consumers, and how elite fish species affect on its quality.

It is 2,600 cubic meters per day. The water treatment facilities of the Amur GPP with such capacity are able to provide potable water, for instance, to a village with a population of 4 thousand people. The water passes through 2 filtration stages before it gets to its consumers. First of all, the water is made clear of undesirable impurities, including excess iron, manganese, and organic substances.

The next stage is clarification and disinfection. The last stage is UV disinfection at the water treatment facilities of the industrial giant.

«These are UV disinfection units. They are necessary for water disinfection. This mean, to treat water to remove microbes and parasites: for instance, total coliforms. So, the water must be clear of enterococchi and other harmful contaminations,» said Viktor Shorokhov, Lead Process Engineer of the water supply and drainage shop of Gazprom Pererabotka Blagoveshchensk LLC.

Water treatment has completed, and the employees can drink the water right at the workplace. Pump house noise doesn't cease. This is the place where the filtrate enters the following tanks: drinking water, process water, fire fighting water, and the filtrate will also be used for the needs of the Amur GPP. Besides, water is tested daily in the environmental analytical laboratory. Water of appropriate quality is supplied to the administration buildings and industrial facilities of the industrial giant.

Sewage treatment facilities are another important part of the utilities, infrastructure and offsites. Commissioning is in full swing here. All units are capable of operating at negative 50°C. This is the place where 90 percent of the wastewater from the three sewage facilities of the plant will be collected and pass through 4 wastewater treatment stages.

«After treatment, all wastewater of the Amur GPP will comply with the standards established for fisheries reservoirs. Besides, these standards are more stringent in Russian law. And such water will be quite appropriate both for a trout lake and for any reservoirs where the Amur sturgeon is also found,» noted Aleksandr Kovalev, Head of Environment of NIPIGAS JSC.

Water treated to almost 100 percent will be stored in special tanks. And water from those tanks will be used for process needs as well as the fire fighting system.
