5-500 TPD Compact Modular Domestic Wastewater Treatment Plant with A/O Biological Process for Residential Areas

Product Overview

Our 5-500 TPD (Ton Per Day) domestic integrated sewage treatment system is a modular, skid-mounted, and fully decentralized wastewater treatment solution tailor-made for residential communities, villa zones, suburban residential blocks, and scattered residential clusters. Covering a full processing capacity range from small 5-ton daily output to medium 500-ton daily output, the system perfectly matches the differentiated sewage discharge demands of low-density villa communities, mid-sized residential compounds, and large-scale residential districts. Different from traditional bulky centralized sewage treatment plants, this integrated equipment integrates all core treatment units into a compact integral structure, realizing on-site collection, on-site treatment and on-site discharge or reuse of domestic sewage. It solves the  points of long-distance pipeline laying, high construction cost and low treatment efficiency in residential area sewage treatment, becoming the preferred eco-friendly solution for modern residential community water environment governance.

Core Technology & Working Principle

Adopting mature and efficient A/O biological treatment process and optional upgraded MBR membrane bioreactor technology, the system combines physical filtration, biochemical degradation, solid-liquid separation and disinfection sterilization to form a full-stage sewage treatment process. The built-in grille pretreatment unit intercepts large suspended solids such as hair and domestic waste to avoid equipment blockage. The regulating tank stabilizes water quality and water quantity to eliminate the impact of peak sewage discharge in residential areas. The anaerobic-aerobic biochemical tank efficiently decomposes organic matter, ammonia nitrogen and total phosphorus in domestic sewage through microbial flora. The secondary sedimentation tank realizes automatic sludge separation, and the final disinfection unit thoroughly removes harmful bacteria and microorganisms. The whole process operates continuously and stably, with no secondary pollution. The optional MBR process further improves sewage purification accuracy, making the effluent quality reach higher reuse standards.

Product Advantages

Application Scenarios & Effluent Standard

This series of integrated sewage treatment systems is mainly applicable to urban residential communities, suburban villas, rural centralized residential areas, community supporting living quarters and other domestic sewage treatment scenarios. The flexible capacity design of 5-500TPD covers small single-villa sewage discharge, medium community daily sewage treatment and large residential cluster centralized treatment needs. After treatment, the effluent stably meets national and international residential sewage discharge standards. The conventional process reaches Grade 1 B standard, and the MBR upgraded process can reach Grade 1 A standard. The treated clean water can be directly discharged or reused for community greening irrigation, road cleaning, toilet flushing and other domestic water purposes, realizing water resource recycling and reducing community water costs.

Installation & After-sales Service

The equipment features simple installation and short construction cycle. It does not need complex civil engineering construction, only basic foundation treatment is required, and the whole machine can be quickly installed and put into operation within 3-7 days. We provide one-stop overseas services including customized scheme design, equipment production, transportation guidance, on-site installation guidance, commissioning and after-sales maintenance. All products support personalized customization according to customer's site conditions, sewage quality and treatment requirements, ensuring that each set of equipment can achieve the best treatment effect and operating state for residential sewage governance.
