Environmental protection, consistent product quality, process optimization and safety –​ just a few reasons why liquid analysis is becoming increasingly essential. Liquids such as water, beverages, dairy products, chemicals and pharmaceuticals have to be analyzed day in and day out. We support you in fulfilling all these measuring tasks with application know-how and cutting-edge technologies. Discover our comprehensive portfolio and choose the product best suited to your process needs.

Evoqua's OMNIFLO® SBR MAX system with Jet Tech technology combines the benefits of a true-batch SBR with the benefits of a continuous fill batch reactor process to treat wastewater influent flows to over 5 times design.  The OMNIFLO SBR MAX system optimizes hydraulic handling during storm flows, reduces equipment sizing and cost, and can trim energy costs over 15%!

Improved oxidation ditch mixing efficiency, lower energy use, and reduce maintenance with Envirex® Disc Aerators from Evoqua. Envirex disc aerators fit all existing single or multichannel oxidation ditch applications with little or no modification required.

The Aqua-Jet® SS-PW surface mechanical aerator, manufactured by Aqua-Aerobic Systems is certified to NSF/ANSI 61 by UL for use in potable water applications. These units can be utilized for THM stripping applications or circulation in potable water treatment systems and reservoirs with a minimum volume of 100,000 gallons.

The PASSAVANT® surface brush aerator MAMMUTROTOR® provides a transfer of oxygen into the activated sludge tank and optimal mixing of the activated sludge, ensuring an even distribution of biomass, organics and oxygenated water creating ideal conditions for biological activity.

The Thermatel® Model TA2 thermal mass flow transmitter, based on thermal dispersion technology, provides reliable mass measurement for air and gas flow applications.

SANITAIRE® is the trade name recognized throughout the wastewater treatment industry for quality products and advanced technology. The In-Place Gas Cleaning System is recognized world wide for its ability to clean porous ceramic fine bubble diffusers in-place, efficiently and without interruption to the process or dewatering of aeration tanks.

The VariOx™ jet aeration system is an aeration and mixing device used in numerous water and wastewater treatment applications. Jet aeration combines many of the benefits and efficiencies of both mechanical and diffused air type systems. The jet aerator consists of an inner liquid nozzle and an outer air nozzle. Liquid from the basin is re-circulated through a jet motive pump and discharged through the inner liquid nozzle at a high velocity. Concurrently, air is fed into the outer air nozzle where it is mixed with the motive liquid and discharged as a high energy jet plume.

There are many reasons for a utility to rent a blower for wastewater aeration. Besides the obvious — an emergency — plant operators may need a rental to bridge the gap during upgrade projects, supply seasonal need to supplement air, or perform testing.

A combination of urban sprawl, more stringent environmental regulations, and aging facilities is putting a huge strain on the wastewater operations at many municipalities. The good news is that membrane aerated biofilm reactor technology, also known as MABR, offers a compact and energy-efficient solution.

Improving wastewater treatment efficiency requires some type of change in the physics, biology, or economics of the process. In this Water Talk interview, Jeff Kelly, Red Valve’s senior product manager for the Tideflex Aeration and Mixing System, describes how to change all three — to the tune of a cost-saving 50-percent reduction in applied airflow! The Tideflex approach uses a unique diffuser design to support on/off aeration and mixing cycles without clogging. Managed by oxidation-reduction potential (ORP) readings, the novel technique supports a biological selection process that encourages the exclusive growth of facultative anaerobes — the most resilient wastewater microbes, which get rid of phosphates and nitrates without producing hydrogen sulfide.

Population growth, stricter regulations, and increased energy costs continue to exert significant pressure on municipal wastewater operations. But rather than investing in tired, old solutions such as the construction of additional concrete tanks, water system managers are seeking new ways to stretch the limits of their infrastructure.
