Working principle:It is adopted compound material to manufacture, degrees 30-40 incline with a piece of active plate in the place of funnel where flow water down. This plate close at ordinary time, when it is rain, the plate will be open automatically under the force of rainwater, rainwater enter sewer through the defender. It is valid to solve the problem that closing rain water opening without influencing exhaust water normally, therefore prevent mosquitoes, cockroaches and other insects flying out ,stopping their main concealing place and multiplying resources.Products specification:It is depend on the customers demands.The scope of usage:It is used widely for rainwater opening of sewer in municipal engineering, realty agency, and residential community.

With the innovation and study, BEC Company has successfully developed the technology of producing hard polyvinyl chloride spiral pipe with 300-3500mm in diameter, equipment and plastic sectional material for particular use with the pipe. The new technology acquires Chinese invention patent and awarded with PCT international patent that has passed The Eurasian Patent Organization, The European Patent Organization, The South Africas Patent Organization, African Regional Industrial Property Organization, The Asia's Patent Organization and IP Australia. Different from other techniques which focus on the circle rigidity, the new technology allows the surrounding soil to share the load with the flexible pipe and adopt multi layers, achieving to 40% of deformation without leak, preventing second time of pollution, that all mean the breakthrough for the flexible pipe born from theory into reality. The large caliber spiral winding pipe can resist acid and alkali corrosion. Suitable for in-door

Teco ltda. Is a colombian based firm that engineers and manufactures compact waste water treatment systems for domestic use. Our systems are based on fixed film activated sludge technology with ringlace media and ventery aeration. The systems require very little maintenance and has a very high efficiency of over 90%. We are searching for partners in India, China and Africa to market and eventually manufacture our systems in these countries. We have over 100 eco-pac systems supplied in several latin American countries like Colombia, venezuela, Mexico and many of the caribbean islands. Our systems are made 100% by us (except the water pump) and are constructed in fiberglass. The submerged fixed film is also made by us in Colombia with polyvinylidene chloride fibers located on our reactor. The aeration system is also made 100% by us, where we use our own ventury system connected to a simple and low maintenance submergible pump. All systems have measurements that can be easily fi
