Domestic Sewage Waste Water Treatment Equipment For Industrial, Agricultural, Food Factories, Slaughterhouses

Dissolved air flotation sewage treatment plants are usually used for primary sewage treatment, and the front can be used together with grilles(bar screen). The compact sewage treatment plant is the second treatment, and the disinfection system (sodium hypochlorite, chlorine dioxide) is tertiary.

Domestic Sewage Wastewater Treatment Equipment for Industrial, Agricultural, Food Factories & Slaughterhouses

Domestic sewage and industrial wastewater generated by factories, farms, food processing plants, slaughterhouses, commercial facilities, and other operations require effective treatment before discharge or reuse. Our Domestic Sewage Wastewater Treatment Equipment is designed to provide reliable wastewater collection, solid-liquid separation, biological treatment, clarification, filtration, disinfection, and sludge management for a wide range of applications.

Different wastewater sources contain different levels of suspended solids, organic matter, fats, oils, nutrients, microorganisms, and other pollutants. A properly designed Wastewater Treatment System can be configured according to the wastewater characteristics, daily flow rate, discharge requirements, and available installation space.

Comprehensive Wastewater Treatment Solution

Our wastewater treatment equipment can be used for both domestic sewage and industrial wastewater treatment. Depending on the application, the treatment process can incorporate screening, grit removal, equalization, oil separation, anaerobic treatment, aerobic biological treatment, sedimentation, filtration, disinfection, sludge dewatering, and other processes.

For domestic sewage, the equipment primarily targets suspended solids, biodegradable organic matter, ammonia nitrogen, and microorganisms. For industrial wastewater, the treatment process can be customized to address higher concentrations of COD, BOD, SS, oil and grease, nutrients, and process-specific pollutants.

The complete system can be supplied as a compact integrated unit or as a combination of individual treatment equipment. This makes it suitable for new wastewater treatment facilities as well as wastewater system upgrades and expansions.

Industrial Wastewater Treatment

Industrial facilities often generate wastewater with significantly different characteristics from domestic sewage. Manufacturing plants, processing facilities, workshops, and commercial operations may produce wastewater containing high concentrations of organic matter, suspended solids, oil, grease, or other contaminants.

Our Industrial Wastewater Treatment Equipment can be configured with pretreatment and biological or physicochemical processes according to the wastewater analysis. Equalization tanks can help stabilize fluctuations in flow and pollutant concentration, while screening and sedimentation systems remove larger solids before downstream treatment.

For wastewater with high organic loading, biological treatment systems can provide efficient degradation of biodegradable pollutants. Additional filtration, chemical treatment, or disinfection can be incorporated when required by the application.

Agricultural Wastewater Treatment

Agricultural operations can generate wastewater from livestock farms, agricultural processing, washing operations, and other activities. This wastewater may contain suspended solids, organic matter, nutrients, and agricultural residues.

An appropriately designed Agricultural Wastewater Treatment System can combine solid separation, equalization, biological treatment, clarification, filtration, and disinfection. For livestock-related wastewater, pretreatment is particularly important because manure, fibers, and other large solids can affect downstream equipment.

The treatment process can be selected according to the farm size, wastewater characteristics, seasonal variations, and local discharge requirements.

Food Factory Wastewater Treatment

Food processing facilities typically produce wastewater containing high levels of biodegradable organic matter, suspended solids, fats, oils, and grease. Wastewater characteristics can vary considerably depending on the type of food being processed.

Our Food Factory Wastewater Treatment Equipment can be designed with screening, grease removal, equalization, biological treatment, clarification, and sludge treatment. Pretreatment helps protect pumps and biological equipment while improving the stability of the overall system.

For food factories with variable production schedules, an equalization stage can help balance wastewater flow and pollutant loading before biological treatment.

Slaughterhouse Wastewater Treatment

Slaughterhouse wastewater generally contains blood, fat, grease, suspended solids, proteins, and high concentrations of biodegradable organic matter. Effective pretreatment is therefore essential.

A typical Slaughterhouse Wastewater Treatment System may include mechanical screening, solid separation, grease removal, equalization, anaerobic or aerobic biological treatment, sedimentation, filtration, and disinfection.

Removing coarse solids, fats, and grease at the beginning of the process can significantly reduce the load on biological treatment equipment and help maintain stable operation.

Main Treatment Processes

Depending on project requirements, our wastewater treatment systems can integrate several treatment stages:

1. Pretreatment: Screens, grit removal equipment, and solid-liquid separation systems remove larger particles and floating materials.

2. Equalization: Equalization tanks balance variations in wastewater flow and pollutant concentration.

3. Biological Treatment: Aerobic or anaerobic biological processes use microorganisms to reduce biodegradable organic pollutants.

4. Sedimentation: Clarifiers separate biological sludge and suspended solids from treated water.

5. Filtration: Sand filters, multimedia filters, membrane systems, or other filtration equipment can provide additional polishing.

6. Disinfection: Chlorination, ultraviolet disinfection, ozone, or other methods can be selected according to the final water quality requirements.

7. Sludge Treatment: Excess sludge can be concentrated, dewatered, stored, or further processed according to the project requirements.

Compact and Flexible System Design

For locations with limited installation space, compact integrated wastewater treatment equipment can combine multiple processes within one system. Containerized and skid-mounted configurations can also simplify transportation and installation.

For larger industrial projects, individual tanks and treatment units can be arranged into a complete customized wastewater treatment plant. The system can be designed around the required treatment capacity rather than relying on a one-size-fits-all configuration.

Our wastewater treatment equipment provides several advantages for industrial and commercial users:

Suitable for domestic sewage and industrial wastewater
Flexible treatment process configuration
Suitable for food processing wastewater
Designed for slaughterhouse wastewater treatment
Applicable to agricultural and livestock wastewater
Effective removal of suspended solids and organic pollutants
Optional biological, filtration, and disinfection processes
Compact solutions available for limited spaces

Operation and Maintenance

Correct operation and routine maintenance are essential for maintaining treatment efficiency. Operators should regularly inspect screens, pumps, blowers, aeration systems, sludge equipment, valves, and control systems.

The biological treatment stage should be monitored for factors such as dissolved oxygen, sludge condition, pH, and loading. Sludge should be removed or dewatered according to actual operating conditions to prevent excessive accumulation.

Pretreatment equipment also requires regular cleaning, particularly in food processing and slaughterhouse applications where grease, fibers, solids, and organic residues can accumulate quickly.
