Manhole chimney seals
Cretex Specialty Products provides flexible, mechanical internal and external manhole frame-chimney seals for use on sanitary sewer manholes. The seals stop manhole frame-chimney inflow and infiltration, creating a durable seal for the top of a manhole. The company also offers internal manhole and pipe joint seals, external joint wraps, lid plugs, lid gaskets and inflow dishes to prevent leakage of water into manholes.

Pump system management
Grundfos Remote Management is an internet-based telemetric system that provides operators with timely information about their pump systems. When an alarm occurs or a value triggers a warning limit the system will send an alarm SMS or email to a mobile phone or computer. Managers can plan on-call schedules months in advance. The schedule determines who is to receive alarms at any given time of the day or night all year round. From a PC, a Smartphone, or a Tablet PC anywhere the recipient can log on to the system and determine the course of action to be taken.
OpenCEL's focused pulse sludge pre-treatment systems enhance anaerobic digester performance and provide supplemental carbon addition to be used for denitrification. Using Waste Activated Sludge (WAS) from the system, digesters can produce more biogas which will be converted to energy. Moreover, biosolids output from a plant will be reduced, saving disposal costs and reducing a plant's environmental impact.

KLa Systems has developed a skid mounted Slot Injector™ manifold system for installation into existing basins without the need to take the basin out of service. The directional injector manifolds can be used in aerated lagoons, oxidation ditches and circular tanks to provide both oxygen transfer and mixing to meet the process requirements. The aerators are fabricated of vinyl ester FRP pipe with polypropylene injectors and a galvanized steel support skid.

Innovyze has released its V11 Generation of H2ONET for AutoCAD® 2013, enabling engineers to work faster and more efficiently with very large network models. Built atop AutoCAD®, the software provides integrated real-time network modeling, GIS data exchange, spatial database query and analysis across multiple data types, and the sophisticated mapping essential to complete infrastructure (asset) management and business planning.
Ashbrook Simon-Hartley's Klampress technology can match the specific dewatering needs of every application. With seven basic configurations, each one of the North American sludge types can be dewatered to optimum dryness. The Klampress Type Z is suited for dewatering applications that benefit from vertical roller stacking. It elevates operator "ease-of-use" for tower type presses to the Klampress standard and introduces energy savings and long-term durability to the tower option.
Gas injection systems
Water and wastewater treatment plants can more efficiently control pH, biological oxygen demand (BOD), dissolved organics and odors with high-performance gas injection systems from Linde North America. The company offers oxygen, ozone and carbon dioxide gas-dissolution systems that can significantly improve treatment process efficiencies while helping utilities meet environmental requirements often at a lower cost than existing treatment methods. To decrease biological oxygen demand, dissolved organics and odors, Linde offers the Solvox® process, which provides an effective supplement or replacement to forced air systems. Since air is only 21 percent oxygen, the oxygenation process can be almost five times more efficient.
Linde North America
Asahi/America has introduced the Quarter Master (QM) Remote Cycle™ self-powered actuators. These units consist of a Series 94 electric actuator with self-powered battery and open/close timer mounted to a ball or butterfly valve for use in remote areas where power sources are limited or unavailable. The system features a NEMA 4X engineered resin enclosure with stainless steel trim, on/off switch, adjustable open and interval times via dip switches, and manual override.
