Intake Screens

Traveling Water Screen offered by us assist in meeting the demands of intake water screening which is of utmost importance for protecting downstream equipment like pumps and condensers from malfunctioning. These traveling water screens can be operated either continuously or intermittently, depending on the process requirements at client s end. Further, as the water flows through screen, baskets typically made of MS/ SS/ fiber glass in varying size meshes along with endless band of screening baskets helps in removing the debris from moving water. This, the debris collected on mesh panels is raised to deck level as well as are removed by back washing. The finer mesh screens can also be used for increased debris removal. The baskets, mounted to two strands of chain also allow smooth travel to top of the screen. Having been used for decades, these water screens are successfully used in water intakes of: Nuclear thermal power stationsSteel worksMunicipal and other industrial units Features: Completely eliminate debris carryover downstream of systemIdeal for high water volumes as well as heavy debris removalProtection of down water equipment Types of traveling water screens Broadly, traveling water screens are of two types: Thru flowDual flow type Having successfully executed various types of travelling water screens, these specially designed commissioned stainless steel travelling water screens operate smoothly in inhospitable environment in open sea condition at: Nuclear Power Corporation India, Tarapur Unit

Apollo Screens intakes provide continuous water extraction from Rivers Lakes Dams Ocean Advantages The all welded construction offers unmatched features and benefits Wedge wire screening Maximum efficiency Protection of aquatic life Controlled slot velocity Less maintenance Non Moving parts Low pressure drop Engineered to suit specification Industry Segments Municipal Water Supply Water Treatment Plants LNG Plants Desalination Paper Pulp Sugar Mills Waste Water Treatment and various other process Industries Our Intake system Passive screening is designed to reduce initial cost and reduce maintenance of your water intake system. It is based on two fundamental concepts: Reduced infow velocity and Use of natural currents or gravity for cleaning. Limiting the maximum screen through velocity to 0.15 m/s, minimizes the build-up of solids and aquatic organisms on the screen. The low screen entrance velocity and minimum clogging conditions result in very low head loss across the screen surface. In cases of extremely high loads of debris in the water body or inadequate current conditions an air backwash system for auxiliary cleaning may be incorporated into the screen assembly. During the air backwashing cycle debris is flushed away from the wedge wire screen surface, by a burst of compressed air released inside the screen cylinder. The air backwash system can be manually or automatically operated, based on a timer or pressure drop set-up to suit the system supplied. The Apollo Screens wedge wire water intake screens are supplied in Single or Tee configurations specifically designed to suit individual applications in rivers, lakes, dams or ocean. Flexibility in Design Each System is engineered and manufactured to individual applications. E.g. Size, Air backwash system, material selection and many more. Intake apertures are typically 3 mm, but larger apertures can be offered to suit customer requirements. Intake aperture smaller than 2 mm are not recommended, due increased chance of algal growth. The Apollo Screens intakes are typically fabricated from 304 SS and 316 SS. Other materials such as 904L can also be offered. The head loss through the Apollo Screens intakes is very low, typically 1.5 kPa through a single screen and 2.5 kPa through a tee screen. Taking into account the application requirements (depth, water quality, aperture, total flow rate), Apollo Screens will provide you with the optimum financial and technical solution.

Surface Water Intakes

Passive Half Intake Screen

Intakes for drinking water, plants, fish hatcheries, industrial process water, power plant cooling water, desalination plants and many other applications require careful design consideration in order to responsibly protect the aquatic life at the intake. Intake screens equipped with Johnson Screens' primary filtration Hydroburst system is designed to reduce slot entrance velocity 0.5 f/s / 0.135 m/s. Lower entrance velocity protects surrounding aquatic life and prevents debris clogging. This technology can be implemented wherever high volumes of surface water are required.

Water Intake Screens

MACMET's Travelling Band Screens are classified, depending on the pattern of water flow: Through-Flow Band Screen Water flows through the Through-Flow Band screens, effectively using 50% of the submerged mesh area. Mesh sizes range from 4 to 10 mm. The retained solids are discharged into a refuse trench. Dual Flow Band Screen Water flows from outside to the inside of the Dual-Flow Band screens, effectively using 100% of the submerged mesh area. Mesh sizes range from 4 to 10 mm. The retained solids are discharged into a refuse trench. Centre Flow Band Screen Water flows from inside to the outside of the Centre-Flow Band screens. The configuration of the baskets ensures 150% use of the submerged mesh area. Mesh sizes range from 0.1 to 10 mm. The retained solids are discharged into an internal collecting trough. The water flow patterns enforced by the Dual Flow Band Screen and Centre Flow Screen ensure that debris is not carried over. The Through-flow TBS and Dual-flow TBS have flat basket design whereas the Centre-flow TBS has a semi-circular basket design which ensures a much higher capacity for removing debris/trash. The baskets in Centre-flow TBS have a retaining plate, which gives this TBS the characteristics of a bucket elevator. The Centre-flow TBS takes the help of gravity for discharging much of the debris, thus requiring less back wash for its screens. Centre-flow TBS can handle up to 1,00,000 m3 flow of water per hour with optimal filtering out of debris owing to its highly efficient screening capacity. A Centre-flow TBS also scores over the other two types of TBS by requiring less civil construction owing to its higher sump level. The mesh size is determined by the quality of water required to be processed. Thus, to ensure screening out of tiny particles, fine mesh is used. In case of power utilities and desalination units, the mesh sizes are generally 1 mm to 2 mm. No further filtration is required to provide clear water for the plant. Macmet has supplied the largest Water Intake System in India consisting of 10 lines channeling 63,000 cu.m. to 82,000 cu.m. water to Coastal Gujarat Power Ltd. Macmet has also supplied one of the largest intake systems in the country, consisting of 6 channels of 55000 cu.m per hour and 2 channels of 8000 cu.m per hour for Nuclear Power Corporation. The first Centre flow Band Screen operating in India was supplied for a capacity of 25,000 cu.m per hour with 2 mm screen opening. In Europe and other developed nations, Centre flow type Travelling Band Screens are more commonly used than the other two type of screens because of the efficiency and ease of operation. Centre-flow Band Screens are also environmentally friendly, as they can be designed for fish recovery. Fishes are segregated from the debris through low pressure water jets and channeled to a separate trough for disposal.
