[...]Modular design for high flexibility Low operating costs due to low-maintenance plants Filter bed cleaning during system operation Effluent quality requirements for municipal and industrial wastewater treatment plants are becoming increasingly demanding and complex. To reliably meet the more stringent effluent standards, many applications require additional advanced treatment stages. The HUBER Sandfilter CONTIFLOW® is a versatile, reliable and, above all, low-maintenance filter system for such applications. It can be used for advanced municipal wastewater treatment (3rd and 4th treatment stage) as well as for the treatment of industrial and process wastewater in order to provide individually adapted process solutions tailored to meet specific requirements and conditions. Design and Function The HUBER Sandfilter CONTIFLOW® is a deep-bed type upflow filter with continuous filter bed cleaning and meets even the highest effluent quality requirements. The system is highly efficient as no shutdowns for backwash cycles are necessary for the sand washing process. The HUBER Sandfilter CONTIFLOW® is available as a steel tank design or concrete basin design. Its modular design ensures the optimal treatment of any throughput. The feed is introduced into the Sandfilter through a series of feed radials at the bottom of the filter. As the influent flows from the bottom upward through the sand bed, the solids contained within the influent are retained in the filter sand. The filtrate exits over a weir at the top of the filter. The sand bed, along with the accumulated solids, is drawn downward to the trough bottom into the airlift pipe, which is located in the centre of the filter. The airlift transports the mix upwards to the sand washer. Inside the washer, the solids are separated from the filter sand with a small portion of the filtrate flow. The clean sand falls down through to the bed, generating an internal sand circulation. Typical HUBER Sandfilter CONTIFLOW® applications In addition to mechanical filtration (filterable solids reduction, phosphorus elimination, removal of microplastics), the Sandfilter is also used for biological filtration (nitrogen reduction by denitrification, post-filtration for ozonisation in the 4th treatment stage). Tertiary treatment Reliable retention of suspended solids Easy phosphorus removal through flocculation filtration Reliable removal of microplastics (>99.9 %) Fourth treatment stage Proven police filter before ozonation or activated carbon filtration (GAC) Proven post-filtration following ozonation or activated carbon filtration (GAC) Other applications Treatment of industrial process water, cooling and circulation water Treatment of surface waters and removal of algae Denitrification for biological nitrogen reduction The Benefits of the HUBER Sandfilter CONTIFLOW® Versatile system, sturdy design, well proven over many years No complicated, cost-intensive backwash technology for filter bed cleaning Optimum efficiency due to the use of filtrate as wash water Sand bed cleaning without shutdowns Continuous filtration saves operating and investment costs Modular design for easy adaptation to any flow rate Easy to retrofit on existing sewage treatment plants Gravity feed without pumps High operating reliability due to constantly high filtrate quality No moving parts and only one wearing part for easy maintenance[...]

[...]Containerised SafeDrink plants combine all components for coagulation, flocculation, clarification, filtration and disinfection in a compact system. The MENA-Water drinking water plant SafeDrink is a cost effective packaged plant that meets WHO and other international treated water standards. It is easy to operate, consumes less energy and can be delivered in short notice. Its versatile design makes it ideal for potable water treatment for cities and villages and industrial process water. It can also be used for grey water treatment and as advanced treatment of wastewater or to reduce suspended solids, phosphorus and other contaminants like heavy metal. Design and Function Coagulation Coagulating chemicals are injected in the pipe to be mixed with the raw water. Coagulants promote collisions between the small suspended particulates, called colloids, enabling them to form large flocs that settle easily in the clarifier leaving behind clear water with very low turbidity. Clarification The coagulated and flocculated water is evenly distributed at the bottom of the lamella settler using well designed distribution laterals. The large surface area of the tube settler causes the flocs to settle by gravity to the bottom thickening zone. The sludge is periodically withdrawn through an automatic valve. Clarified water is collected from the clarifier surface through perforated tubes. Filtration Clarified water enterst he high rate gravity filter for removal oft he remaining finer solid particles. Based on the application, the filter media can be dual media or multi-media. The water passes through the layers of the media and passes an underdrain system. The filter is backwashed intermittently depending on the influent turbidity of the raw water. Disinfection Disinfection can be with liquid or gas chlorine. Ultra violet disinfection also can be used. Applications: Potable water for cities and villages Process water treatment Grey water treatment Optional Equipment to Customize the System: Many options can be provided to suit the site, such as Pre-settling unit for highly turbid water Pontoon to carry the feeding pumps Power generator Storage tanks as ground or elevated tower Portable small Laboratory for water quality testing Containerized operator rooms Skid mounted pumps alternatives as serf priming Process Steps The following process steps are arranged inside the container housing. This achieves in very small footprint at site and very quick realization times. Coagulation Coagulating chemicals are injected in the pipe to be mixed with the raw water. Coagulants promote collisions between the small suspended particulates, called colloids, enabling them to form large flocs that settle easily in the clarifier leaving behind clear water with very low turbidity. Flocculation The coagulated water enters the flocculation area. A coagulant aid or polymer can be added to strengthen the floc bonding. Slow stirring motion forms collision between the forming precipitates and the remaining contaminant particles to form larger flocs. Clarification The coagulated and flocculated water is evenly distributed at the bottom of the LAMELLA SETTLER using well designed distribution laterals. The large surface area of the tube settler causes the flocs to settle by gravity to the bottom thickening zone. The sludge is periodically withdrawn through an automatic valve.
