BioTechnology Ltd.

"BioTechnology" Ltd. is a leading Bulgarian engineering company, specialized in the field of ecology and wastewater treatment projects. From conception to completion and throughout the entire lifecycle, we are dedicated to every stage of the project: production, construction, assembling and installation of water treatment plants. The company is established in 2005 with a registration certificate implemented a quality management system ISO: 9001:2008.We produce and assemble modular wastewater treatment plants and have a wealth of experience in providing water treatment solutions for municipal, industrial and domestic sectors ranging from turnkey packages to the design and construction of extensive water treatment facilities.Our solutions adapt to Clients’ specific requirements. With growing environmental concerns, the world of water treatment is constantly evolving. We use quality assured design, innovative project management and equipment, identifying emerging technologies and developments within the industry. At Bioteh we design wastewater treatment facilities and complex process control systems.From conception to completion right through to design, build, installation, operation, maintenance and support, we oversee every stage of the project. As specialists in the power, control and automation, and water treatment industries, we satisfy individual needs, demanding innovative, bespoke packages. Our central office is located in Sofia, but we have trade representatives in many cities in Bulgaria. We place great emphasis on fostering effective partnership to ensure trust and understanding form the basis of our working relationship. We assume the role of domestic and foreign partnership rather than simply contractor or supplier. Our qualified team is constantly identifying emerging technologies and developments within the industry. Materials and equipment of Bioteh wastewater facilities- The material we use is polypropylene and polyethylene of the German company SIMONA- Air compressors - SECOH Japan- Centrifugal pumps and breakers - BIBUS Switzerland- Blowing systems - BIBUS Switzerland- Control microprocessor for the cycle of the purifying facilities with distant or computer observance. Advantages of Bioteh Ltd. - Flexible pricing policy- Design and construction of various purification facilities regarding the individual client’s requirements- Qualified personnel services maintenance of the purification facilities - Trade representative offices and trained staff in many Bulgarian cities- Quality laboratory analysis of the purified water- Microprocessor for control and low cost management of the wastewater plant- Changeable working regime of the installation according to the different flowing parameters- Odorless- Reduced volume of the final sediment- Stabilizing of the receded active sediment in aerobic conditions- Low exploitation expenses- Minimum exploitation requirements- 98% guaranteed quality of the purified wastewaters- 36 months guarantee Technology Mechanical pre-treatmentWastewater flows by gravity from the sewerage system through stainless fine bar rack. Impurities are captured there, otherwise they could damage the equipment. Cached impurities are manually removed and disposed into nearby container.Biological treatmentIn designing of waste water treatment plant it is necessary to choose the appropriate type of technology able to reach satisfactory parameters in reducing organic pollution and removing nitrogen and phosphorus compounds from polluted wastewater. The D–N (denitrification – nitrification) technology along with chemical phosphorus precipitation, applied in the system under consideration, is the most appropriate one for satisfying the relevant water quality standards. This technology is implemented by design of the wastewater treatment facility introducing two activation zones with different technological conditions. In aerated (nitrification zone), ammonia is oxidised to nitrates by bacteria in presence of dissolved oxygen. The wastewater treatment plant BioTechnology has the following technological zones:- Denitrification (anoxic) compartment - for full nitrate removal and partial BOD decrease;- Nitrification (aerobic) compartment – for full ammonia oxidation to nitrate in aerobic conditions, aerobic oxidation of the remain organic matters and phosphorus removal by chemical precipitation (installed by the decision of the customer).- Compartment for UV disinfection - installed by the decision of the customer.- Sludge aerobic digestion and thickening compartment - excess activated sludge is pumped to the digestion zone, where it is thickened by gravity. Sludge holding tank is aerated by fine-bubble aeration elements. learn more Products Household - WWTP 2 - 30 /People Equivalent/The wastewater treatment facilities ВТ 5 – ВТ 30 are designed to treat small sources of wastewater such as family houses, villas, holiday villages and small factories. Medium - WWTP 40 - 150 /People Equivalent/The wastewater treatment facilities ВТ 50 – ВТ 150 are designed to treat medium sources of wastewater such as small settlements, hamlets, hotels placed out of towns, camping sites, motels, petrol stations and some small industrial enterprises. Municipal - WWTP 200 - 2000 /People Equivalent/The wastewater treatment facilities type ВТ 200 – ВТ 2000 is designed for purification of large secondary sources of wastewater: villages, resorts, small towns, camping sites, hotels, housing cooperatives and some industrial enterprises with domestic faecal contamination. Pump Stations and Inspection ShaftsThe technology created by BioTeh for decentralized canal systems is suitable for hill areas, areas with high underground waters level and firm base. For these areas the standard canal systems and central waste water treatment plants are very expensive.The BioTeh pump stations eliminate the necessity of the traditional gravitational canal, DECREASING significantly the investment costs ABOUT 40-60%, depending on the area. Grease InterceptorsThe Grease Interceptors are designed to collect oils and fats flowing out of kitchens, food and meat processing operations, etc. The oils and fats are precipitated and collected in the Grease Interceptors to protect the sewer and other parts from being fouled and clogged up.Waste disposer shall not be installed before the grease interceptor. Using the kitchen disposer is not allowed due to the excessive loading of the interceptor with organic matter (the sewer does not serve as a transport system for the waste, and neither does the grease interceptor serve as a cleaning unit or a sludge sump). Plastic Reservoirs and Containers for LiquidsThe plastic tanks are being used for constant or temporary collection unit for waste or already purified waters. The producer requires them to be used accordingly to their purpose.The main technical parameters of the plastic tanks are shown in the specification table. Their working volume is reached when the water level reaches the low end of the inlet or outlet tube if such is required. Swimming Pools from PolystoneBioTeh OOD builds, installs and maintains swimming pools from polystone. Polystone is a kind of material, which belongs to the group of thermo-plasts, having very good physical-mechanical properties and hygienic characteristics. In the pools, built with this material may be kept foods and also aggressive things. The material has a stabilizer for double UV protection and it will withstand even the most drastic climate changes while keeping its hydro-isolation characteristics, which allows the construction of indoor and outdoor pools. Water Disinfection- Purification of waste waters- Purification of drinking water- Recycling of waste waters- Swimming pools and aqua parks- Food industry- Hospitals- Pharmaceutical industry- Electrical Industry- Cosmetic industry- Fish farms Services - Production, Delivery, Installation and commissioning of treatment plants for municipal wastewater and industrial uses from 2 to 10 000 /people equivalent/.- Production of pumping stations, grease interceptors, plastic tanks and swimming pools.
