Water Metering Supports Sustainable Water Management Solutions
Water Metering Supports Sustainable Water Management Solutions

The term “carbon footprint” has been on everyone’s lips since the start of the climate change discussion. Very few industries can claim that they play no part in impacting the carbon footprint — either for good or bad. This is also true for the water and wastewater industry that will have to take a closer look at increasing the efficiency of their facilities to reduce their carbon footprint.

  • VFD Energy Savings For Pumping Applications
    VFD Energy Savings For Pumping Applications

    In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

  • Reducing Total Phosphorus In Water Resource Recovery Facilities
    Reducing Total Phosphorus In Water Resource Recovery Facilities

    Monitoring phosphate during the wastewater treatment process allows for fine-tuning and optimizing chemical dosing for removal of phosphate, which provides significant cost savings to the plant while protecting the aquatic environment downstream of the facility.

  • Reduce SBR Maintenance Costs With Jet Aeration
    Reduce SBR Maintenance Costs With Jet Aeration

    Aeration has been a primary method for treating municipal and industrial wastewater for over a century. It is a natural way to reduce biological oxygen demand (BOD) and control odors. In the SBR process, aeration helps foster nitrification by bubbling air through the mixture of wastewater and activated sludge, encouraging the multiplication of aerobic microbes which consume nutrients and convert ammonia into nitrites and nitrates.

  • Optimizing Air Flows To Aeration Basins
    Optimizing Air Flows To Aeration Basins

    As a result of clean energy mandates and the rising cost of energy, wastewater treatment facilities around the country are retrofitting their instrumentation to run highly efficient, cost-effective, clean facilities. To reduce emissions and produce clean energy, solid wastes are often digested in large digester tanks to reduce the volume of waste (sludge) and produce more biogas, which is then used as fuel in the cogeneration process. However, a clean environment calls for not just clean air and clean energy, but clean water as well.

  • Chemical Cost Comparison Of A Conventional Deaerator vs. A 3M™ Liqui-Cel™ Membrane Contactor System
    Chemical Cost Comparison Of A Conventional Deaerator vs. A 3M™ Liqui-Cel™ Membrane Contactor System

    Mixed bed ion exchange is often used to polish reverse osmosis (RO) permeate in many industrial water systems. This process has been utilized for several years and it is well known that the management of the dissolved carbon dioxide (CO2) in the water is critical for an efficient operation. By Membrana

Brewery Wastewater Treatment Systems Brewery Wastewater Treatment Systems

ClearBlu provides sophisticated wastewater treatment equipment scaled to small to large size craft brewers.  This allows brewers to stage in treatment as it’s required by the municipality, or if you are located in an area without sewer access.  We also provide complete systems in package or pond format.

FiltraFast™ Extreme-Rate Compressible Media Filter FiltraFast™ Extreme-Rate Compressible Media Filter

FiltraFast™ is a high-rate downflow gravity or pressure filter that uses a unique compressible media. The filter only uses hydraulic loading to create the required media porosity without any mechanical compressing devices. A proprietary backwash sequence enables maximum recovery, extends media life, and limits energy consumption. This process 1) significantly reduces the footprint compared to sand filters, and 2) reduces maintenance and replacement costs required by disc filters, and other compressible media filters.

  • Growing And Flourishing In A Desert
    Growing And Flourishing In A Desert

    Water is essential to life. And it is a very precious commodity in Israel, home to 9 million people living in a rocky desert that receives about 10 inches of rain a year. By comparison, Denver, considered semi-arid, gets about 15 inches of rain a year, which is about a fourth of the precipitation a tropical city such as Miami receives.

    Can We Turn Sewage 'Sludge' Into Something Valuable?

    Over the past few years I have become an academic expert in “sewage sludge” — the residual, semi-solid mix of excrement packed with microorganisms that is left behind within wastewater treatment plants. Every year the UK alone produces approximately 1.4 million tons of the stuff. About 80 percent of it is spread on fields as manure, but this still leaves us with a headache — what do we do with the rest?
