Building/Structure

Legacy Building Solutions tension fabric buildings

Tension fabric buildings from Legacy Building Solutions provide a high level of flexibility for a variety of building applications. They use a durable, rigid frame in place of hollow-tube, open web truss hoop framing. The strength of the structural steel frame provides the ability to easily customize buildings to the exact width, length and height required. In addition to long clear spans, the buildings have straight sidewalls that maximize the useable square footage inside the structure. The design allows for the ability to add lean-tos, mezzanines and sidewall doors. The structures are engineered to provide desired overhangs or handle additional loads for items such as sprinklers and conveyors. The solid structural steel I-beams are not vulnerable to unseen corrosion originating inside a tube. There are multiple coating options available for all steel components, including hot-dip galvanizing, primer and powder-coat paint. 877-259-1528; www.legacybuildingsolutions.com

Environetics Defender tank covers

Defender tank covers from Environetics are custom manufactured from industrial-grade materials to fit the profile of a new or existing wastewater treatment tank or potable water tank. They contain volatile organic compounds at their source. Low-profile structurally supported covers minimize emission treatment volume to reduce the cost of air filtration equipment. They can help eliminate the ongoing expense of applying costly odor control chemicals through atomizer and misters. 815-838-8331; www.environeticsinc.com

Industrial & Environmental Concepts Odor  Control Covers

Odor Control Covers from Industrial & Environmental Concepts can be designed to be semigas or 100% gastight. They are designed with an impermeable flexible membrane to contain odors while still enabling access for equipment maintenance or sampling. The covers are commonly used on sludge/liquid tanks and aerobic and anaerobic systems. The company’s Disinfection Covers block penetrating sunlight and are commonly used over chlorine contact chambers. The result is reduced algae and chlorine loss due to volatilization, which improves disinfection and lessens chlorine demand. Both covers are maintenance-free and long-lasting. 952-829-0731; www.ieccovers.com

Media

Kruger USA Anox K5 Media

ANITA Mox is a sidestream deammonification technology that is offered in both moving bed biofilm reactor and integrated fixed-film activated sludge configurations, depending on site conditions. As such, the system consists of engineered polyethylene carriers — Anox K5 Media from Kruger USA — to provide ample protected surface area for biofilm to thrive. The media (approximately the diameter of a quarter) hosts two types of bacteria in the same reactor. The outer layer consists primarily of ammonia oxidizing bacteria, which convert about half of the ammonia to nitrite. The inner layer consists mainly of anaerobic autotrophic ammonia oxidizer bacteria, which utilize the resulting nitrite and much of the remaining residual ammonia and convert them to nitrogen gas that is released harmlessly to the atmosphere. 919-677-8310; www.veoliawatertech.com

SUEZ Water Technologies & Solutions FiltraFast

The FiltraFast media filter from SUEZ Water Technologies & Solutions is designed for treatment of high flows and includes compressible media to enable up to 10 times the loading rate of conventional media filters. The high-rate downflow gravity or pressure filter uses hydraulic loading to create the required media porosity with no mechanical compressing devices. The backwash sequence is designed to enable maximum recovery, extend media life and limit energy consumption. FiltraFast units are available in different configurations and can be customized to specific applications. Based on project requirements, units can be fully shop-assembled and delivered, or erected on site. www.suezwatertechnologies.com

Mixers

JDV Equipment Nozzle Mix System

The Nozzle Mix System from JDV Equipment is a dual-zone mixing technology that provides uniform mixing patterns that produce even distribution and a stable environment. It can help optimize solids suspension and contact to promote efficiency in a wide range of applications. The system is designed with pumps installed outside the tanks to facilitate ease of maintenance. The pumps are typically chopper pumps or pumps incorporating in-line grinders that prevent fibrous materials from accumulating and causing plugging problems. The application dictates which type(s) of the many varied pump options can be used. The high-velocity nozzles are mounted inside the tank and are oriented to discharge in a flow pattern that completely mixes the tank contents. 973-366-6556; www.jdvequipment.com

Pulsafeeder mixers

Pulsafeeder mixers have a 304 stainless steel shaft with an integral impeller(s). Epoxy and vinyl shaft coatings are available for applications where the solution being agitated is not compatible with stainless steel. The Bracket Mount Mixer mounts to the tank cover or flat surface with four bolts and two 3/8-inch steel brackets holding the mixer securely in place. The Flange Mount Mixer provides a convenient and economical means of mounting smaller mixers. The mixer can be mounted directly to the tank cover or other flat surface. It can also be mounted directly onto Pulsafeeder 35- and 55-gallon solution tanks featuring rigid covers. Thread Mount Mixers provide a simple means of mounting smaller mixers onto tanks or drums with a bung hole in the cover. Thread mounts have a 2-inch nipple, which screws directly into a standard bung, cutting labor and cost for drilling mounting holes. 800-333-6677; www.pulsatron.com

SUMA America agitator propellers

During the stirring process, abrasive and aggressive liquids can cause considerable wear on stirring blades. Agitator propellers from SUMA America combat this issue, as they are designed to not lose substance over time when exposed to aggressive media. In order to increase the service life, the manufacturer relies on an elastic, durable and multilayer polymer reinforcement. The polymer-coated propellers are protected against corrosion. The material is UV resistant, abrasion resistant and impact resistant, and it prevents fungal attack and microbial development on the propeller. 847-427-7880; www.gosuma.com

Vaughan Rotamix

The Rotamix system from Vaughan is a reliable means of mechanical hydraulic mixing for sludge tanks, digesters and other high-volume applications. It incorporates several basic principles of physics and hydraulics, including uniform and vertical fields of flow, induced flow and surface contact. Using custom engineering software, each application is analyzed and sized in order to achieve the desired mixing effect. Combined with a Vaughan chopper pump, this mixing system optimizes solids contact due to the homogeneous state. The system may be applied in circular, rectangular or oval tanks and basins, and other process configurations such as egg-shaped digesters, combined sewer overflow tunnels and pump stations. 888-249-2467; www.chopperpumps.com

Pittsburg Tank & Tower Group ROV inspections

Potable tanks should be inspected every three to five years, according to the American Water Works Association. Pittsburg Tank & Tower Group performs this service using a remotely operated underwater vehicle. The inspections don’t require tanks to be drained. Instead, a disinfected ROV is placed inside to gather images with its video equipment while a trained operator manipulates the robot safely outside the tank. The robot has high-definition video recording capabilities. Inspections usually take about two to three hours. Once finished, the company provides a video of the ROV inspection to the customer. 270-869-9400; www.pttg.com
