Municipal Wastewater Treatment

Municipal Wastewater Treatment
Shijiazhuang Liquatech Environmental Technology Co., Ltd. supports expanding urbanization by integrating wastewater services into the water cycle of each city. We undertake environmental responsibility and offer all solutions on a turnkey basis for water resources protection. Our municipal wastewater treatment equipment is able to treat increasingly complex effluents in accordance with ever more stringent discharge standards.

We design, build and operate the municipal wastewater treatment networks and systems of small communities, towns, medium and large major cities. For rural areas where the service territory is too small or hard to reach, we offer small wastewater package solutions—prefabricated and integrated wastewater treatment plant.

To manage sewage treatment systems efficiently, we have designed a comprehensive approach tailored to confront the local dimensional, technical and regulatory challenges. The success of municipal wastewater treatment projects is ensured by clearly defined steps, including needs assessment, local strategy, quality guarantee, service performance measurement and communicating to residents about the impact of the service.

Our experience continues to grow on the basis of intensive research work. Therefore, in addition to standard technical processes, we are also able to offer highly efficient new developments. Our proven and advanced processes include:

1. Anaerobic Biological Process
• upflow anerobic sludge blanket
• sludge digester

2. Aerobic Biological Process
• activated sludge process (fine bubble diffused aeration)
• activated sludge process (surface aerators)
• activated sludge process (jet aeration)
• trickling filters/bio towers
• sequential batch reactors
• membrane bioreactors (submerged)
• membrane bioreactors (external skid mounted)

3. Physiochemical Process
a. oil removal
• belt type oil skimmers
• oil and grease separator
• floating oil skimmers
b. chemical treatment and sedimentation
• rapid coagulation
• slow speed flocculator
• conventional clarifiers
• high rate reactive clarifier
c. tertiary treatment
• dual media filters
• multimedia filters
• rapid sand gravity filters
• dual media gravity filters
• pressure sand filters
• activated carbon filters

We ensure that only clean water is discharged into rivers, meeting all local standards of concerned authorities. In addition, through a combination of innovative municipal wastewater treatment processes, we facilitate the reutilization of wastewater for industrial and municipal purposes and thus achieve the conservation of resources.
