In†the modern world, when the future of†our Planet depends on†the level of†progress, care of†natural resources is†extremely important. Waste water treatment is†among the significant issues in†the todayís agenda. Engineering and process solutions proposed by†ECOS are able not only to†minimize undesirable emissions to†water basins and atmosphere, but also to†remarkably reduce Clientís expenditures of†finance and energy.
The main sewage treatment methods are:
Physical-chemical method. It†includes mechanical screening stage for extraction of†big size waste, grit and floating materials, and chemical treatment stage, when colloid solutions and other contaminants are destroyed with chemicals and settled. Physical-chemical method includes also different kinds of†filtration: micro-filtration, ultra-filtration, nano-filtration and reverse osmosis.
Biological method. Today biological treatment is†applied to†most kinds of†industrial and sanitary waste water containing organic and biogenic contaminants. This type of†treatment is†based on†ability of†some bacteria to†decompose organic materials and biogenic elements to†elementary substances like water, carbon dioxide and other simple chemical elements. This sewage treatment process nature is†mineralization of†organics. In†other words, we†call Nature for help, and contaminations are destroyed by†Oxygen and bacteria. At†this stage our experts work on†selection of†micro-organisms and creation of†favorable conditions for its living and reproduction. ECOS sewage treatment plants ensure high quality of†treated water, allowing discharge to†First class fishery ponds.
Is†it†possible to†use only one method for high quality treatment? As†practice shows, physical-chemical method can provide the required removal of†contaminations. At†the same time biological method is†more natural and safe for the environment and†ó the important thing†ó it†is†much more cheap. From the other side, presence of†some kinds of†suspended materials and poisonous chemicals (pesticides) in†sewage effluent from industrial plants kills micro-organisms available at†the biological treatment stage.
ECOS Company successfully combines both described methods in†its sewage treatment plants. To†provide optimal combination of†all factors is†very special task, making influence on†size of†the treatment facilities, power consumption, efficiency and cost. ECOS is†capable to†find the optimal solution due†to:
- skills and experience of†its engineers who can use the scientific research results for development of†the most efficient combination of†treatment processes;
- ability of†upgrading the existing treatment facilities in†addition to†construction of†new ones, and therefore reducing negative impact on†the environment;
- treatment facilities installed by†ECOS operate with minimum harm to†the environment and at†the same time provide saving of†capital cost and energy.
