Pentair is a global company dedicated to building a safer, more sustainable world. Pentair delivers industry leading products, services and solutions that help people make the best use of the resources they rely on most. Its technology moves the world forward by ensuring that water is plentiful, useful and pure, and that critical equipment and those near it are protected. With 2016 revenues of $4.9 billion, Pentair employs approximately 19,000 people worldwide.
We report the performance of our business within two segments:
Designs, manufactures, markets, and services products that guard and protect some of the world’s most sensitive electronics and electronic equipment, as well as heat management solutions designed to provide thermal protection to temperature sensitive fluid applications and engineered electrical and fastening products for electrical, mechanical and civil applications.
Designs, manufactures, markets, and services innovative water solutions for the toughest filtration, separation, flow and water management challenges in agriculture, aquaculture, foodservice, food and beverage processing, swimming pools, water supply and disposal, and a variety of industrial applications.
The treatability of high-strength wastewater with conventional anaerobic wastewater treatment is limited by the concentrations of FOG (Fats, Oils and Greases), high salt concentrations and high levels of COD (Chemical Oxygen Demand) or solids. Increasingly high discharge fees and ever stricter legislation have been strong drivers in the development of anaerobic membrane bioreactors (MBRs).
Pentair developed a cutting-edge technology that combines anaerobic digestion and membrane separation to generate biogas and a high quality of reusable water.
Conventional anaerobic granular systems have many limitations. The formation and settlement of the sludge granules is hampered when the concentrations of FOGs, salt or COD become too high.
Pre- or post-treatment is often required to prevent the washout of granules and achieve stable bioreactor performance. Moreover, the COD removal efficiency of conventional anaerobic techniques is only 70-90 percent.
There is no need for granules or DAF in an anaerobic MBR. The absolute membrane barrier retains the biomass in the system, where it will start to flocculate and achieve higher mass transfer rates due to the larger surface areas. Longer retention times allow fats to be easily degraded into biogas. Pre-or post-treatment is often not required at all, and the COD removal efficiency of anaerobic MBRs is typically more than 99 percent.
