3 Introduction About ORTHOS Liquid Systems, Inc... For more than 20 years ORTHOS has been supplying designs and components for our monolithic concrete filter floor system. The system is a cast in-situ design that becomes part of the surrounding civil structure. Unlike other suspended filter floor systems there is no risk of degradation or structural failure that may lead to the requirement of a refurbishment in years to come. snozzles.com The system is easy to install, allowing the installation to be completed to a very high standard of accuracy. Unlike the thermoplastic forms used by other manufacturers, GRC, or Glass Reinforced Cement, is a strong material that forms a key with the concrete sub floor. Our GRC filter panels are easy to install and, when used with reinforcing steels, demonstrate a dramatic reduction in corrosion rates. ORTHOS offers a complete engineered package for the monolithic floor. We can supply all designs, documentation, calculations and technical components required for efficient installation and commissioning. Because of the modular supply of the system, we are able to remove risks of on site design and quality control, delivering a packaged system ready for installation. However, by utilizing local supply of standard materials, such as steel reinforcement and concrete, we are able deliver a high quality engineered product at a very competitive price. Both options of design, shown on the previous page, have been utilized in a wide range of applications around the world, including: Rapid gravity sand and multimedia filters Activated carbon contactors Tertiary filters on sewage treatment plants Up flow sand filters Biological up flow filters 03

7 Filter Nozzles Full line of nozzles offer cost effective retrofit solutions... When it comes to filter performance of a nozzle underdrain system, it is vital that the nozzle being used is properly designed to meet your specific filter specifications. With multiple design options such as material, mounting style, flow rate capacity and tailpipes for air scour, we are sure that Orthos Liquid Systems has a filter nozzle that will meet your requirements. We are capable of replacing any OEM design on the market by supplying a direct replacement, or if required redesigning, the nozzle to ensure optimum filter performance. Mechanically locked screens Reinforced cages V shaped slots to prevent clogging Nozzles have NSF 61 certification Made in the USA Resin Traps Prevent Catastrophic Resin Loss of your system... Their installation can help prevent: Loss of expensive resins Cross contamination of resins Costly downtime and process disturbance Environmental damage 07
