MENA-Water Potable Water Plant SafeDrink Cost effective packaged plant meeting all WHO and international standards.
Containerized 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.
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 flows into the flocculation area, where a coagulant aid or polymer can be added to enhance floc bonding. Slow stirring facilitates collisions between the forming precipitates and remaining contaminant particles, leading to the formation of larger, more robust flocs.
Clarification
The coagulated and flocculated water is evenly distributed at the base of the LAMELLA SETTLER using carefully designed distribution laterals. The extensive surface area of the tube settler promotes gravitational settling of the flocs into the bottom thickening zone. Sludge is periodically removed via an automatic valve, while clarified water is collected from the clarifier surface through perforated tubes.
Filtration
Clarified water enters the high rate gravity filter for removal of the 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.
