Sewage Treatment Plant

Integrated wastewater treatment equipment adopts A/O process, A2/O process, or A/O-MBR process, combining biological degradation, wastewater sedimentation, disinfection (optional as needed), and other processes into a single system for the treatment of domestic wastewater and industrial wastewater similar to domestic wastewater. The equipment features a compact structure, small footprint, and can be fully installed underground. It operates economically, offers strong resistance to shock loads, achieves high treatment efficiency, and ensures easy management and maintenance. The treated wastewater maintains stable quality, meeting the Class A or B standards of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB18918-2002). The equipment can be buried underground or installed above ground, with treatment capacities ranging from 24 to 500 m³/d. For capacities exceeding this range, special customization is required.

Membrane Bioreactor (MBR) is an advanced wastewater treatment technology that combines efficient membrane separation with the activated sludge process. It integrates the advantages of membrane filtration and biological treatment, significantly enhancing the effectiveness of biochemical processes. MBR systems are particularly suitable for treating municipal and industrial wastewater with high organic content.

The MBR system utilizes hollow fiber membranes to achieve solid-liquid separation. The NL series immersed hollow fiber membrane module is specially developed for this purpose. It offers high filtration efficiency, effectively removing bacteria, suspended solids, and other impurities, resulting in superior water quality. Additionally, each membrane module provides a large filtration area while occupying minimal space. This compact design reduces the overall volume of the bioreactor and the required installation footprint.

Membrane bioreactor is a kind of new type sewage treatment technique which combine high efficient membrane separation technique and activated sludge manner, it inherit membrane separation technique and biochemical treatment technique feature and intensify biochemical treatment effect, it can used in high organic content municipal or industrial sewage treatment.
MBR system use hollow fiber membrane to make solid-liquid separation. The NL series immersed hollow fiber membrane is special developed membrane module. It has higher filtering efficiency, it can effective remove bacteria、suspended particles and impurity, thus get the superior filtering water. In additional, due to each unit membrane module filtering area big, small membrane installation occupy volume, decrease reactor volume and occupy area.

Ultrafiltration is a pressure driven membrane separation process that removes suspended or particulate matter ( including colloids & silt )
from water. Ultrafiltration is more reliable than conventional multimedia filtration that removes approx. 10 micron or larger matter where a UF membrane pore size ranges from0.01 to 0.10 micron. Ultrafiltration also efficiently removes bacteria and most viruses.
The UF system offers a high recovery rate and outstanding product quality, enabling efficient separation, purification, and high-concentration processing of liquids.

Seawater desalination equipment is an essential solution for addressing water scarcity. With its exceptionally high desalination rate, it efficiently converts seawater into fresh water suitable for safe consumption and use. The equipment boasts stable and reliable performance, requiring minimal maintenance during operation, and is environmentally friendly, producing no pollution. Its compact structure and small size make it ideal for installation in a variety of locations, from seaside factories to remote islands, without occupying significant space. Additionally, the system is user-friendly, with easy operation and straightforward maintenance, making it a practical and sustainable choice for water supply needs in diverse environments.

The principle of integrated sewage treatment equipment is mainly to convert organic matter in sewage into harmless substances through the metabolism of microorganisms, so as to achieve the purpose of purifying water quality. This equipment usually consists of four stages: pre-treatment, biological treatment, MBR membrane (optional) and post-treatment.

Reverse Osmosis (RO) is a filtration process that utilizes semi-permeable spiral-wound membranes to remove dissolved solids, organic matter, pyrogens, submicron colloidal particles, color, nitrates, and bacteria from water. Under pressure, feed water passes through the membrane, allowing purified water, known as permeate water, to pass through its microscopic pores. Meanwhile, the concentrated impurities are separated and discharged as reject water, also called concentrate water.  
RO membranes are widely used in various small-scale systems, including household water purification, hospital and laboratory cleaning, and other specialized water treatment applications. They provide high flux performance comparable to conventional low-pass filtration while effectively removing salts and contaminants.
