Pros & Cons - Moving Bed Bioreactor Technology
A moving bed bioreactor is a biological wastewater treatment process. In many instances, wastewater is full of organic matter that can be difficult to filter out by chemical or physical means. Therefore, one of the best methods of dealing with organic matter is treating it with a biological process. The basic idea behind the biological water treatment processes is using micro-organisms to break ...

Membrane Bioreactor Pilot
The problem A company which produces a product that requires a constant supply of relatively clean water is planning to expand by adding new process units online. The plant currently uses well water as a supply to its production. The water production from the well is limited. They need to install a system to produce reuse water to reduce the amount of water required from the onsite well in ...

Membrane Bioreactor for Water Mining in New York City
The Facility The Helena, which opened in late 2005, is an apartment building that offers more than amenities, views, and nice finishes. Behind the $100 million tower’s gleaming glass and metal skin is a serious high-performance building. Its owner and designers say the Helena will annually use 65 percent of the energy and one-third of the potable water of comparable properties. The ...

Application of nanofiltration for reuse of wastewater
The present research is a part of efforts to reuse wastewater by applying nanofiltration (NF) method for the secondary treatment of bio–treated wastewater and to check the quality of product water as irrigation water by using various analytical methods. For this, the performances of three different NF membranes (CK, GE–Osmonics; NF–270 and NF–90, Dow–FilmTech) were investigated using a cross–flow ...

Small-bioreactor platform technology as a municipal wastewater additive treatment
The bioaugmentation treatment approach presents both an economical and environmentally friendly solution for wastewater treatment. However, the use of exogenous bacterial cultures presents several limitations: negative interaction between microorganisms and adaptation to new physical and chemical composite environment. These selective forces create a significant challenge for the introduced ...
