The existing sewage treatment processes have problems such as high investment costs, high operating costs, high sludge production, unsatisfactory effluent discharge standards, and low regeneration and reuse rates. At present, domestic sewage from residential communities is directly discharged into municipal sewage treatment plants for treatment, which increases the burden on municipal sewage treatment plants. In some off grid areas such as rural areas, due to the lack of sewage treatment facilities, untreated sewage is directly discharged, causing serious environmental pollution.

The State Council has issued the Action Plan for Water Pollution Prevention and Control, which puts forward clear requirements for the effluent quality and treatment technology innovation of sewage treatment facilities, including:

The effluent quality of urban sewage treatment facilities needs to meet the Class A discharge standard.

2. Develop and promote technologies such as safe reuse of recycled water, remediation of groundwater pollution, ecological restoration of water, and low-cost and high-quality treatment of domestic sewage.

MAA - Natural Ecological Water Purification System is an innovative wastewater treatment technology aimed at improving effluent quality, reducing costs, achieving wastewater resource utilization, and restoring ecosystems.
