Municipal WWTP

Location:Town of Plymouth, USA


Treatment Capacity:19 m³/d

WWTP Type: Integrated FMBR Equipment WWTPs

Process: Raw Wastewater→ Pretreatment→ FMBR→ Effluent


Project Brief:

In March 2018, in order to discover the leading edge new technologies in the field of wastewater treatment and achieve the goal of reducing the energy consumption of wastewater treatment, Massachusetts, as a global clean energy center, publicly solicited cutting-edge technologies for wastewater treatment globally, which was hosted by Massachusetts clean energy center (MASSCEC), and carried out innovative technology pilot in the public or authorized wastewater treatment area of Massachusetts.

The MA State Environmental Protection Agency organized authoritative experts to conduct a one-year rigorous assessment of the energy consumption benchmarks, estimated consumption reduction targets, engineering plans, and standard requirements of the collected technical solutions. In March 2019, the Massachusetts government announced that Jiangxi JDL Environmental Protection Co., Ltd.’s “FMBR Technology” was selected and granted the highest funding ($ 150,000), and a pilot will be conducted at the Plymouth Airport Wastewater Treatment Plant in Massachusetts.

The effluent treated by FMBR equipment is generally stable since the operation of the project, and the average value of each index is better than the local discharge standard (BOD≤30mg/L, TN≤10mg/L).

The average removal rate of each index is as follows:

COD: 97%

Ammonia nitrogen: 98.7%

Total nitrogen: 93%

Location:University of Massachusetts Amherst Water and Energy (WET) Testing Center


Treatment Capacity:25 m³/d

WWTP Type: Integrated FMBR Equipment WWTPs

Process: Raw Wastewater→  FMBR→ Effluent


Project Brief:

JDL is operating a pilot project using FMBR technology at University of Massachusetts Amherst Water and Energy Technology (WET) Testing Center located in 240 Mullins Way Amherst, MA 01003. The purpose of the pilot is to prove that FMBR technology can achieve high biological nutrient removal (BNR) performance for domestic sewage treatment.

The pilot project adopts packaged FMBR equipment with a design capacity of 6,600 GPD. The influent is pumped from the nearby Town of Amherst Wastewater Treatment Plant (TOA WWTP) and the effluent after treatment is discharged back to the primary clarifier tank of the TOA WWTP. The pilot will monitor the BOD5, COD, ammonia, total nitrogen and total phosphorus. The pilot began on April 22nd, 2024 and will last for 6 months (3 months in summer and 3 months in winter). On May 2nd, 2024, JDL hired the UMass WET Staff to conduct 3rd party measurements of total nitrogen (TN), ammonia, (NH4), and chemical oxygen demand (COD). 

The average removal rate of each index is as follows:

COD: 93.6%

Ammonia nitrogen: 99.5%

Total nitrogen: 91.1%

Location: Lianyungang City, China

Time: 2019

Treatment Capacity: 130,000 m3/d

Project Brief:

In order to protect the local ecological environment and highlight the appearance of a livable and industrial coastal city, the local government chosed FMBR technology to build a park-style ecological sewage treatment plant.

Different from the traditional sewage treatment technology which has large footprint, heavy odor, and above-ground construction mode, the FMBR plant adopts the ecological sewage treatment plant construction concept of "above ground park and underground sewage treatment facility". The adopted FMBR process removed the primary sedimentation tank, anaerobic tank, anoxic tank, aerobic tank, and secondary sedimentation tank of the traditional process,and simplified the process flow and greatly reduces the footprint. The entire sewage treatment facility is hidden underground. After the sewage passes through the pretreatment zone, FMBR zone, and disinfection, it can be discharged and used as water for plant greening and landscape while meeting the standard. As the discharge of residual organic sludge is greatly reduced by FMBR technology, there is basically no odor, and the plant is environmentally friendly. The entire plant area has been built into a waterscape leisure plaza, creating a new model of sewage treatment plant with ecological harmony and reclaimed water reuse.

Project Brief:

In order to solve the environment issues caused by domestic sewage, and to effectively improve the quality of urban water environment, and at the same time, considering the disadvantages of traditional sewage treatment plants, such as large land occupation, heavy odor, need to stay away from the residential area and huge investment in pipe network, the local government chose JDL FMBR technology for the project, and adopted the concept of "Park aboveground, treatment facilities underground" to build a new ecological sewage treatment plant with a daily treatment capacity of 10,000m3/d. The sewage treatment plant is built near the residential area and covers an area of only 6,667m2. During the operation, there is basically no odor and the organic residual sludge is greatly reduced. The whole structure of the plant is hidden in the underground. On the ground, it is built into a modern Chinese garden, which also provides a harmonious ecological leisure place for the surrounding citizens.

Location: Huizhou City, China

Treatment Capacity: 20,000 m3/d

WWTP Type: Integrated FMBR Equipment WWTPs

Process: Raw Wastewater→ Pretreatment→ FMBR→ Effluent

Project Brief:

The Coastal Park FMBR STP is located at Huizhou City. The designed domestic wastewater treatment scale is 20,000m3/day. The main structure of the WWTP is intake tank, screen tank, equalization tank, FMBR equipment, effluent tank and measuring tank. The wastewater is mainly collected from the coastal park, aquatic product wharf, fisher wharf, dragon bay, Qianjin wharf and residential areas along the coast. The WWTP is built on the seaside, closed to the residential area, has a small footprint, few residual organic sludge discharging and no odor in daily operation, which does not affect the surrounding environment.
