Industrial water treatment

The wastewater from this type of industry is characterized by high volume, organic loading and solids content.Тhe main sources of their generation being the processes of slaughter, cutting and blanching, as well as cleaning of facilities and channels. The offered equipment works extremely well in terms of the separation of solids from oils and fats, and in the treatment of process water from slaughterhouses where the removal percentage of total load can reach up to 95%. The offered technological solutions are suitable for use in slaughterhouses, sausage factories, factories for semi-finished foods, etc. and it has found application inbuilt sites in the municipalities of Sandanski and Dryanovo.

Characteristic of this type of wastewater formed mainly during the washing of the equipment and the sterilization process is the high concentration of fats and oils in them, the presence of streams with different pH levels, the presence of high amplitudes in the discharge of water, and the discharge of so-called whey. The offered equipment has found its successful application in water purification from dairies in different places on Bulgarian territory, including the municipalities of Vratza and Turgovishte.

This type of industrial waters are generally characterized by a high content of suspended solids, dissolved organic materials and proteins. Depending on the specific activity of...

The wastewater from these industries obtained in the process of cleaning of the incoming products and bone extraction has a high chemical oxygen demand (COD) due to the high content of organic materials, solids, oils and fats, in some cases accompanied by a high level of nitrogen. When processing seafood, process water may be seawater, leading to high concentrations of chloride, sulfate and sodium. To avoid salinity problems, certain components or all equipment may be made of stainless steel. Our equipment can be used in the treatment of water formed in fish and seafood processing plants, canning factories and more.

There is great variability in the process waters of these industries depending on the used raw materials and the production technologies. Colours, additives, biodegradable organic content or inhibitors are present in the various categories. In addition, they can be highly corrosive, so materials specially adapted to the operating conditions are used in the production of the equipment. The offered equipment has been successfully applied in oil and gas treatment plants, sugar factories, biodiesel production plants, fertilizer plants, paint factories, etc. and has been successfully installed on sites in the municipalities of Etropole and Ruse.

The variety of process waters from these industries is significant depending on the specific activity, but in general they need to reduce the high levels of biological oxygen demand (BOD5) and organic load due to the processes of bleaching, washing and dyeing. of textiles, as well as tanning of leather (blood, sand, manure, fibres, etc.). The offered equipment is successfully used in factories for dyeing of textiles and wool, leather factories, etc. and has been successfully instaled on field site in the municipality of Sliven

Industrial productions of this type use large quantities of water in the production process, which also determines the high wastewater flow rates that need to be treated. The main task that should be achieved in addition to the treatment of water from this industry is the separation in the process of wastewater treatment of paper pulp, which will allow its recycling in the main production. The technological equipment offered is suitable for the treatment of paper production process water from both recycled paper and cellulose and has been successfully instaled on field site in the municipality of Pazardzhik.
