Cloth media filter
The AquaPrime cloth media filtration system is an economical and efficient solution for primary wastewater treatment and wet weather applications. It utilizes a disk configuration and exclusive OptiFiber® cloth media to filter screened, de-gritted, raw municipal sewage. Features allow the system to handle high-solids applications and sustain low effluent TSS, making it ideal for both wet weather treatment and primary treatment in lieu of conventional sedimentation systems. It operates in less than 10% of the footprint of conventional primary settling basins and offers the added advantage of improving gas production in the anaerobic digestion system.
Oasys Water’s family of ClearFlo Water Transformation Solutions are specifically designed to tackle a diverse set of wastewater challenges. ClearFlo Membrane Brine Concentrator (MBC)™ technology recovers more than 90% of fresh water in a simple and reliable membrane process, leaving a greatly reduced water volume to be recovered by the more costly and energy-intensive crystallization process. The ClearFlo Complete is an integrated end-to-end solution combining a pretreatment step with the ClearFlo MBC and adding a greatly reduced capacity crystallizer that together provide a complete liquid recovery solution.
Grit removal system
Hydro International’s HeadCell® advanced grit removal system is a modular, multiple-tray settleable solids concentrator. Its stacked tray design delivers outstanding grit removal efficiency by providing a large surface area in a small footprint, making it ideal for both new and retrofit applications. Using the Advanced Grit Management philosophy, the HeadCell can be designed to remove 85-95% of all grit entering the plant. The system can now be adapted for intermittent operation by incorporating Hydro International’s fluidizing system into the sump and designing an expanded grit pot collector.
Low profile detention system
The StormTech SC-160LP Chamber is 12 inches tall with an installed volume of 15 cubic feet of water for underground infiltration and detention systems. The new unit requires 14 inches of total cover to carry AASHTO HS-20 live loads, which reduces site development costs in shallow applications by minimizing the amount of needed fill and maximizing open infiltrative areas. The chamber requires no separation between chamber rows, making it easier for the contractor to install and also minimizing the aggregate required. It can be installed using an injection molded 8-inch end cap or a solid end cap.
Advanced Drainage Systems
SiC flat-sheet membrane
RODI Systems Corp. is now the exclusive North American distributor for the Cembrane SiC (silicon carbide) ceramic flat sheet membrane. The Cembrane technology provides high flux, low fouling, oil resistance, long life and tolerance to pH and temperature extremes. The Cembrane SiC membrane is chemically inert, oleophobic and has a low pH isoelectric point. These characteristics it an ideal choice for applications such as high TSS and temperature/pH extremes. With features like outside-in filtration, compact design, high flux rate, and superior fouling resistance, the Cembrane product greatly reduces OPEX and required footprint versus other MF/UF filtration systems.

Hollow fiber membrane
DIC Corporation’s proprietary SEPAREL® hollow fiber membrane modules for wastewater and drinking water degasification are hollow fiber membrane modules that remove dissolved gases, such as oxygen and carbon dioxide, in water to prevent the formation of rust and bacteria in water treatment systems. SEPAREL modules can be installed in series within the same water treatment system to ensure sufficient degasification and achieve the desired parts-per-billion level for various water treatment applications. The size of the SEPAREL module is directly related to the flow rate and vacuum pressure of the water treatment system.
Reverse osmosis elements
Both the Lewabrane B400 LE ASD and Lewabrane B400 FR ASD from LANXESS provide for optimized flow in the RO element and thus lower energy consumption. They are optimized for applications in brackish water, have standard geometries (length: 40 inches; diameter: 8 inches) and are characterized by very low energy consumption and high fouling resistance. The feed spacers incorporated in the membrane elements are multifunctional, creating space between the membrane surfaces for fast-flowing water, supporting the membrane in the process and causing turbulent water flow.
