A Better Way for Wastewater

The Regenex System Answers Call for Wastewater Treatment Improvements

 

Across a wide array of industries, industrial wastewater presents generators with complex challenges in its handling, storage, and disposal. Off-site Transfer, Storage, and Disposal Facilities (TSDFs) are often contracted by generators to handle their industrial process wastewater streams and the liability they incur. Due to the substantial amount of water TSDFs process every day, they are frequently in search of cost-effective upgrades to incorporate into their existing treatment “trains.” While tried and true methods of industrial wastewater treatment -biological treatment systems supported by activated carbon beds- serve as a time-tested solution for handling a broad spectrum of waste streams, there remains significant room for improvement. Examining existing treatment stages and the complications thereafter, we have highlighted long-standing barriers in industrial wastewater treatment and discharge that have pushed us to develop a superior solution: The Regenex Treatment System.

 

Existing biological treatment systems and the bacteria they contain successfully neutralize a broad range of prominent dissolved contaminants found in wastewater and are therefore an integral, if not an essential stage in industrial wastewater treatment. Though their value is undeniable, they alone are not a comprehensive solution for responsible wastewater treatment. Despite neutralizing the majority of dissolved contaminants they are frequently tasked with capturing, biological treatment processes cannot fully eradicate dissolved organic contaminants, leaving residual organic contaminants to be dealt with downstream. Furthermore, incoming waste streams with high biological oxygen demand (BOD) numbers can frequently overwhelm biological processing systems, with contaminant concentrations too significant to be processed without co-mingling lower concentration streams beforehand.

 

Tasked with capturing residual contaminants that have passed through biological treatment systems, granular activated carbon (GAC) systems act as a general catch-all for remaining organic contaminants in effluent streams before discharge. Because of the vast number of organic compounds GAC systems capture, their implementation is widespread amongst industrial wastewater generators, disposal facilities, and fluid recyclers. These GAC systems are not without an Achilles heel, however, as the lifespan of the carbon media itself is finite. As a result, when GAC systems become fully saturated, the GAC canisters themselves must be hauled off-site for incineration/disposal; an expensive and time-consuming procedure. Additionally, just as biological treatment systems struggle with high-concentration waste streams, GAC systems suffer their own, increasingly pronounced shortcomings when handling higher concentration streams. Due to their limited capture capacity, GAC systems (namely the activated carbon canisters) do not saturate with time, but volume and concentration of contaminants they are subjected to treating. High concentration streams capable of overwhelming biological treatment systems can be equally problematic for GAC systems downstream, leading to rapid saturation and an overall inefficiency in treatment.

 

In response to these shortcomings of conventional wastewater treatment, the recently developed Regenex wastewater treatment system offers a superior solution for those with wastewater concerns.
