MBBR-BAF Integrated Biofilm Reactor

The MBBR process combines the merits of both the traditional fluidized bed process and biological contact oxidation process, representing a new and highly efficient wastewater treatment technology. Driven by aeration inside the aeration tank and the lifting force of water flow, the carriers are kept in a fluidized state, where suspended-growth activated sludge and attached-growth biofilm are formed accordingly. This allows the moving bed biofilm to fully utilize the entire reactor volume, giving full play to the advantages of both attached-phase and suspended-phase microorganisms so that they can complement each other and offset respective deficiencies. Unlike conventional fillers, suspended carriers can make frequent and repeated contact with wastewater, hence named the "mobile biofilm".

The core technology of the Moving Bed Biofilm Reactor (MBBR) lies in the development of biological carriers with a density close to that of water, which can flow freely along with water under gentle agitation. Such carriers feature a large effective specific surface area and favorable conditions for microbial adsorption and growth. Boasting strong adaptability and a wide range of applications, the MBBR process can be adopted for organic matter removal as well as nitrogen and phosphorus removal. It is applicable not only to newly-built wastewater treatment plants, but also to the process retrofitting, upgrading and renovation of existing wastewater treatment facilities.

HSRO High-Salinity Reverse Osmosis Unit

The reverse osmosis membranes specially designed for high-concentration brine feature excellent high-pressure resistance and outstanding salt tolerance, which can adapt to high-salinity operating conditions. They efficiently retain various salts, heavy metals and pollutants in wastewater with a high concentration ratio, significantly reducing the volume of waste liquid.

The equipment operates stably under automatic control, withstands chemical cleaning and enjoys a long service life, which effectively cuts the subsequent disposal costs of evaporation and crystallization. Widely applied in the concentration treatment of high-salinity wastewater from seawater desalination concentrate reduction, coal chemical industry, electroplating, chemical industry and other fields, this technology realizes wastewater volume reduction and resource recovery. It helps enterprises dispose of high-concentration brine in compliance with relevant regulations and lowers the risk of environmental discharge.

Composite Ultrafiltration Unit

The ultrafiltration membrane unit features high filtration precision, which can efficiently intercept suspended solids, colloids, microorganisms, algae and other impurities to deliver stable and reliable effluent quality.

With a high degree of automation, the equipment boasts a small footprint, low operational energy consumption and convenient cleaning and maintenance. It also has excellent fouling resistance and a long service life, which greatly simplifies the water treatment process flow.

Widely used in tap water purification, reclaimed water reuse, advanced treatment of industrial wastewater, pretreatment for seawater desalination, aquaculture wastewater and domestic sewage treatment, the unit provides stable guarantee for subsequent processes and helps various water treatment projects operate stably up to discharge standards.

Magnetic Separation Device

Magnetic separation technology, also known as rare earth magnetic disc water purification technology), adopts patented magnetic seed processing, demagnetization, micro-magnetic flocculation and dispersion technologies.

Compared with conventional coagulation sedimentation and filtration processes, this technology enables continuous operation and can efficiently and rapidly separate hard-to-settle suspended solids and colloids in water. In terms of process performance, it delivers outstanding treatment efficiency with a short process flow, small land occupation, low capital investment and low operating costs. It boasts remarkable advantages especially in the treatment of black and odorous water bodies such as rivers and lakes as well as water quality improvement of landscape water.

HABR – Hybrid Anaerobic Baffled Reactor

Packing materials are installed in the upper space of each compartment inside the HABR reactor, where a large amount of anaerobic sludge attaches to the fillers, thus making full use of the originally ineffective volume zone. In addition, the installed fillers collide with sludge-entrained bubbles during their upward rising process, accelerating the separation of sludge from bubbles and effectively preventing sludge loss. The fillers can also efficiently intercept particulate organic matter in the influent to achieve its sufficient degradation.

The sludge bed at the bottom contains abundant highly active microorganisms, which can give full play to the capacity of granular sludge for organic matter removal. Therefore, HABR inherits the characteristics of ABR (Anaerobic Baffled Reactor), as well as those of Anaerobic Filter (AF) and Upflow Anaerobic Sludge Blanket Reactor (UASB). It is a new type of high-efficiency anaerobic reactor.

HCPO Reactor

Heterogeneous photocatalytic oxidation is an advanced technology in the current environmental protection field. Its research originated from the photoelectrochemical system composed of TiO₂ photoelectrodes and platinum electrodes, which can decompose water into hydrogen and oxygen. Its working principle is to irradiate the catalyst (typically TiO₂) with light to generate conduction band electrons (e⁻) and valence band holes (h⁺), so as to oxidize and degrade pollutants.

Nevertheless, its practical application is restricted by drawbacks including slow photocatalytic reaction rate, low photon efficiency and insufficient yield of strong oxidizing free radicals. To tackle the existing technical bottlenecks, we integrate photocatalytic oxidation technology with magnetization technology, which has achieved remarkable treatment performance in the disposal of high-concentration refractory organic wastewater.
