Measurit is the distributor of Check-Flex rubber check valves, and we have the biggest inventory of inline and duckbill style valves in Europe. We have supplied valves from 18-2700mm on many innovative drainage designs. Check-Flex rubber check valve facilitates sustainable drainage design by maximising gravity flow and reducing or eliminating pumping costs. The valves are passive and require no external power. Two models of Check-Flex valves, duckbill style and inline style, are available. These models offer the optimum maintenance free and reliable backflow prevention at any location, including severe coastal sites. The fibre reinforced vulcanised construction (similar to a tyre), offers a long service life, over twenty years. The Check-Flex G3 and G4 model duckbill valves are ideal for preventing silt and sand ingress at the end of a pipe. These valves function as variable area nozzles and find application in effluent diffuser systems in rivers and oceans, and mixing systems. The Check-Flex G5 inline valves are an ideal retrofit to resolve odour and backflow problems from municipal sewers. These valves are a universal fit to either the inlet or outlet pipe in a chamber. The direct seal to the pipe by an expanding clamp allows fast and leak free installation. Rubber check valves gained recognition as the default choice for reliable operation in critical backflow prevention in drainage, especially in challenging coastal and estuary locations. Today, Check-Flex valves deliver long maintenance free service life in all drainage applications.

Nereda® technology from Royal HaskoningDHV offers sustainable wastewater treatment solutions for municipal and industrial water. The natural sewage treatment process purifies water with minimal or no chemical usage by using the patented aerobic granular sludge technology. Compared to activated sludge technologies, the biological treatment power of the technology is much larger, while saving up to 50% on energy costs, delivering high quality effluent for low costs and requiring only a quarter of the area of conventional activated sludge installations. Biomass in the process develops as fast settling aerobic granular sludge. These granules have excellent settling properties, so the process does not require a separate time-consuming decant phase like conventional SBR’s. All the biological treatment processes take place simultaneously in the granules, requiring only one tank. The technology is very versatile; it can be developed as a new build or used to retrofit existing conventional CAS or SBR plants. The benefits of the technology include: Excellent treatment results and settling properties: Compared to activated sludge technologies, the biological treatment power of the technology is much larger as a considerably higher concentration of biological active mass is applied that in addition has a much higher content of microorganism that are crucial for biological nitrogen and phosphate removal. Sustainable: Compared to conventional wastewater treatment processes, the technology not only has significantly lower energy consumption and associated greenhouse gas emission, but also produces, commonly without the use of waste generating chemicals, a remarkably high effluent quality. Cost effective: The technology results in construction costs that are lower than for conventional technology as for example, tank volumes are up to four times smaller and less equipment is required. Small physical footprint: Its footprint at sewage treatment plants is reduced due to the full nutrient removal process taking place in one single reactor. Easy to operate: It has proved in operation to satisfy the most stringent purification requirements. Thanks to the nature of the technology, plant operation is easy and process performance robust. The technology is proven and applicable for even the largest applications. Currently, there are over 70 wastewater treatment plants in operation or under construction all over the world
