In municipal drinking water applications or pre-treatment for desalination plants using gravity filters, the filter underdrain is one of the most important components contributing to overall system performance and operation — whether a new filter design or retrofitting an existing filter.
The DE NORA TETRA™ Modular DeepBed Filter Plant from De Nora Water Technologies is designed as a competitive filtration plant for tertiary effluent from small to medium size sewage works. The Modular DeepBed Filter utilizes the technology of DeepBed filtration that has made the TETRA filter such a successful tertiary treatment process over many years in Europe and the United States.
The DE NORA TETRA™ DeepBed™ tertiary filtration system is an economical solution for the removal of total suspended solids and total phosphorus.
The DE NORA TETRA™ Denite® system integrates well with other plant treatment processes to provide superior total nitrogen (TN) and phosphorous removal.
UAT™ Pure Pro seawater desalination membrane filtration systems from De Nora Water Technologies are ideal for offshore oil and gas applications. The standard output capacities range from 2,000 GPD to 26,000 GPD (7,570 LPD to 98,410 LPD) and effectively produce fresh treated potable water, free of particulate matter or contaminants from a seawater source. Higher output capacities and custom configurations are available on a project to project basis.
The Pall Aria™ FIT system illustrates an innovative approach to packaged water systems, featuring a flexible design that is easily tailored for customers’ specific requirements. Systems are pre-assembled and shipped to site for easy and efficient installation, and years of trouble-free operation. With the proven reliability of the Pall Aria™ platform, you can trust Pall to treat all your surface water, groundwater, wastewater, and re-use water. Pall is a global leader in filtration, separation, and purification technologies. Pall Aria™ systems are engineered to eliminate contaminants and deliver pure water for drinking, industrial processes, discharge, and other vital uses.
The Sludge Sucker™ unit is a cable-driven sludge removal mechanism that provides cost-effective and efficient removal of lightweight sludges, such as alum or ferric hydroxide, or light iron and manganese precipitates from rectangular settling basins.
The ROMAG RSW CSO Screen, fitted between the discharge culvert and the relief sewer, reliably retains all visible solids during peak events.
The WesTech RapiSand™ ballasted flocculation system is a high-rate clarification process combining rapid mixing and multi-stage flocculation, followed by sedimentation. RapiSand™ sedimentation is extremely fast and can be applied in a wide variety of suspended solids removal applications.
WesTech granular activated carbon (GAC) pressure contactors are an effective means for removal of various-molecular-weight contaminants from aqueous solutions. They are especially suited for the removal of dissolved organic compounds responsible for poor taste and odor in drinking water, as well as removal of a variety of contaminants that can be found in industrial and municipal waters.
