Water Environment Research Foundation (WERF) notiﬁed BKT that its BBF system has oﬃcially been accepted into the general technology scan of the LIFT program based on additional technical review of its innovative capacity to facilitate carbon diversion.
This announcement follows BKT’s presentation at the WEF/WERF Forum on Intensiﬁcation of Resource Recovery (IR^2) about the beneﬁts of BBF’s application prior to secondary treatment of wastewater. Integration of the BBF increases carbon capture, enhancing the production of energy through digestion gas as well as reducing the amount of energy demanded by the blower to oxidize carbon during secondary treatment. This carbon diversion becomes essential in the future conﬁguration of energy‐neutral water resource recovery facilities such as mainstream deammoniﬁcation, where the resulting low COD/N ratio of BBF eﬄuent will be highly beneﬁcial to such downstream application performances.
As part of this recognition by WERF as an innovative technologies for carbon diversion, BBF will be featured in the LIFT Technology Database, accessible to all WERF Subscribers as a clearinghouse of promising technologies and processes reviewed by leading experts in the water industry. Additional details, will be available to Water Environment Federation (WEF) members and the broader water quality community through the LIFT pages of the WERF website.
In the near future, BBF will be included in the inaugural edition of LIFT Link, anticipated to be available in the ﬁrst half of 2016. An online platform intended to support collaboration and innovation in the water sector, LIFT Link will accelerate BKT’s ability to forge collaborations with municipal utilities, environmental consultants, and other industry experts.
BKT Korea has recently completed development of the FMX‐C, a new model of BKT’s innovative FMX anti‐fouling membrane ﬁltration system. Joining FMX’s four existing models, the FMX‐C customizes the current FMX system for use with a ceramic membrane to expand the product line’s versatility of application and range of capacity.
While the traditional FMX system already promises higher concentration than other ﬁltration methods equipped with conventional polymeric membranes, introduction of the ceramic membrane in the FMX‐C can shift these concentration targets even higher.
Not only can the new FMX‐C provide eﬀective ﬁltration of high‐temperature or highly corrosive inﬂuent but it can also operate in severe conditions would corrode or degrade conventional polymeric membranes. Because ceramic membranes can tolerate elevated temperatures and withstand extreme pH and high operating pressures, the FMX‐C is suitable for many applications where polymeric membranes cannot be used, especially in handling acid liquid materials for the chemical industry.
Furthermore, the durability of the ceramic membrane material, coupled with the FMX’s inherent anti‐fouling features, lowers the frequency of replacement demanded and makes the FMX‐C ideal for in‐place chemical cleaning (CIP) with caustic inorganic compounds or steam sterilization at high temperatures.
BKT’s biological ﬁltration (BBF) system has been approved by the California State Water Resources Control Board as an alternative ﬁltration technology for achieving the minimum turbidity level required under Title 22 of the California Water Recycling Criteria.
Over the last six months, BKT has tested its BBF technology extensively at a pilot plant located at Los Angeles County Sanitation District’s Joint Water Pollution Control Plant in Carson, CA. During this time, BBF has consistently met Title 22 guidelines in normal operation, meeting the turbidity requirement of 2NTU while achieving 93% removal of total nitrogen from non‐nitriﬁed secondary eﬄuent.
A vast majority of wastewater treatment facilities in the United States, most of which were built decades ago, are not able to meet low nitrogen discharge limits. Pollution resulting from the operation of these plants has therefore led to severe environmental problems. The limitations of these existing facilities present a serious technological hindrance for water reuse applications requiring nitrogen removal, including groundwater replenishment.
Now proven to function eﬀectively in ﬁltration, BBF is capable of simultaneously removing nitrogen while occupying equal or less space compared to traditional tertiary ﬁltration options such as sand ﬁlters. This compact footprint makes BBF an ideal choice for retroﬁtting outdated wastewater facilities looking to update their technology with nitrogen removal processes under space limitations.
Worldwide, BBF has over 100 reference sites from small, decentralized wastewater treatment packages to installations up to 190 MGD in capacity. Recently, the City of Barstow, CA selected BBF for use in an ongoing groundwater remediation project to remove nitrates. BBF technology has successfully been applied to municipal wastewater treatment, groundwater remediation, and combined sewer overﬂow (CSO) control.
Anaheim, CA — FMX technology — The South Korean Ministry of Trade Industry & Energy has granted a signiﬁcant Research & Development project to environmental services company BKT. Over the next three years, the South Korean government will budget $6 million, matched by a contribution of $1.5 million from BKT, to facilitate the joint development of an environmentally conscious processing system for eﬃcient reuse of shale gas fracking water.
The design of this new system is intended to incorporate BKT’s unique FMX membrane ﬁltration technology, specialized in high solids, high density, and high viscosity liquid‐solid separation. The features of this easily mobilized FMX unit are particularly crucial to ensuring adaptability to the high ﬂuctuations in the Total Suspended Solids (TSS) content of shale gas produced water.
Founded in 1995, BKT oﬀers a wide range of customized water and energy solutions designed to promote a mission of innovation beyond waste. Since 2011, BKT has been investigating shale gas water reuse extensively, both through internal resources and in collaboration with the US Department of Energy (DOE).
The two‐year DOE project, initiated in 2012 with partner group Southern Research Institute (SRI), is focused on developing advanced technologies that address issues related to processes and methods for handling large volumes of hydraulic fracturing ﬂow‐back water, as well as water produced during the longer term production phase. The program will optimize hydraulic fracturing water treatment and disposal of residues (high‐solid slurry and membrane concentrate) using BKT’s anti‐fouling FMX membrane system.
Thus, BKT now enters this new R&D project equipped with signiﬁcant prior on‐site test experience, ample research data, and extensive partner network. With this additional funding, BKT is expected to move forward more aggressively in the shale gas industry.
“The technical team at BKT is extremely excited to further our existing knowledge,” said Dr. Joon H. Min, President at BKT, “We believe that our tradition of innovation will prove key to advancing technology in contributing a viable solution for environment friendly shale gas water management.”
Global chemical company Nalco‐Ecolab recently placed an order for BKT’s anti‐fouling FMX membrane ﬁltration system in order to integrate BKT’s innovative equipment into its colloidal product manufacturing process. Both BKT and Nalco‐Ecolab have conducted extensive testing over the past three years to prove the equipment’s technological feasibility and adaptability and to optimize the system for Nalco‐speciﬁc applications. As a result, BKT’s engineering team has been able to develop a customized FMX unit specially designed to meet the demands of Nalco’s production process.
Nalco is conﬁdent that the installation of BKT’s FMX ﬁltration system will help improve the eﬃciency of its production processes while maintaining high standards of product quality. The FMX system oﬀers a lower‐maintenance operating process when compared to using conventional membrane ﬁltration technologies.
Since its initial introduction in 2002, FMX liquid‐solid separation technology has been a employed in many applications—including the oil and gas, food and beverage, and chemical manufacturing industries—both in production processes and in wastewater treatment. The system is uniquely suited for applications in which membrane fouling is a signiﬁcant obstacle to sustainable performance because its distinctive technology helps eliminate common membrane fouling problems and extend membrane life.
Many large companies, such as Samsung Fine Chemical and CJ Group, have already adopted BKT’s anti‐fouling FMX system. Currently, FMX is seeing positive reception worldwide, with successful installations in the Netherlands, Belgium, Czechoslovakia, and China, among others. Domestically, BKT has also collaborated with the United States Department of Energy since 2011 to adapt FMX technology for the reuse of shale gas produced water and is now in the process of ﬁnalizing on‐site tests for its mobile FMX ﬁltration unit.
