Domestic wastewater enters the project-specific treatment arrangement.
DECENTRALIZED WASTEWATER TREATMENT
YHWJ-A Carbon Steel Integrated Domestic Wastewater Treatment System
Integrated domestic wastewater treatment equipment with a Q235 carbon-steel shell and project-specific corrosion protection. Treatment capacity, process configuration and buried installation requirements are defined around the wastewater, effluent target and site conditions.
- Wastewater
- Domestic sewage
- Shell material
- Q235 carbon steel
- Capacity
- Project-specific design
- Installation
- Buried, subject to site review
Start with your location, daily flow and effluent requirements.
INSIDE THE CONCEPT
See how the system works
below ground.
A conceptual cutaway connects the inlet, biological treatment zone, aeration, sludge return and outlet within the carbon-steel integrated system.
Biological treatment
MDS suspended media supports attached biofilm within the biological stage described in the brochure.
Aeration & sludge return
Aeration and the brochure-described sludge pre-return concept are finalized in the process design.
Effluent connection
Polishing, disinfection and final discharge arrangements follow the agreed project requirements.
01 / A CLEAR DESIGN BASIS
Match the system
to your wastewater.
Flow is the starting point. Water quality, the required effluent and site conditions determine the final equipment proposal.
| Design input | What to provide | What it determines |
|---|---|---|
| Design flow | Daily treatment volume (m³/day), peak hourly flow and occupancy pattern. | Capacity and number of treatment units |
| Influent conditions | Wastewater source and available COD, BOD₅, SS, ammonia, pH and temperature data. | Treatment configuration and design basis |
| Effluent target | Required discharge limits or reuse requirements for the project location. | Process stages and any polishing or disinfection |
| Site & installation | Available footprint, inlet/outlet levels, groundwater, burial depth and surface loads. | Dimensions, foundation and coating protection requirements |
| Power & operation | Local voltage, frequency, operating hours and preferred control functions. | Electrical specification and operating plan |
| Supply & services | Required equipment scope, inspection, installation support and delivery date. | Quotation, responsibilities and dispatch schedule |

Send your project requirements ↗02 / DEFINE WHAT IS INCLUDED
A coordinated system.
An agreed scope.
Confirm the treatment arrangement and supply boundary before ordering. The technical proposal should identify each included unit and service.
Treatment configuration
Agree the process arrangement, design flow, influent assumptions and effluent targets. The final proposal identifies the included treatment stages.
Equipment & controls
Confirm whether pumps, aeration equipment, control panels and any disinfection or polishing equipment form part of the supply.
Inspection & handover
Agree the inspection scope, available documentation, commissioning support and acceptance method before the order is confirmed.
Your proposal should include
Design basis · Process flow diagram · Equipment schedule · Installation interfaces · Electrical requirements · Inspection and acceptance conditions
03 / PREPARE THE SITE
Plan below ground.
Keep access above.
A buried installation needs a site-specific plan for structural support, service access and ongoing operation.
Foundation & site conditions
- Confirm soil, groundwater, burial depth and surface loading.
- Define foundation, anchoring and anti-flotation requirements in the installation design.
- Agree the corrosion-protection system, handling precautions and any coating repair procedure.
Access & maintenance
- Keep inspection openings and equipment servicing areas accessible.
- Plan ventilation and sludge removal access for the final configuration.
- Include coating condition checks and agreed repair methods in the maintenance plan.
04 / DECENTRALIZED PROJECTS
Where a local treatment
solution is needed.
For domestic wastewater projects outside centralized sewer coverage, with suitability assessed against the actual wastewater and site requirements.
Homes & housing developments
Residential communities
Plan around service population, daily flow and the local discharge requirements.
Decentralized collection
Rural villages
Review collection arrangements, site access and operation resources for a local treatment solution.
Variable occupancy
Hotels & hospitality
Account for occupancy peaks and identify kitchen wastewater or other pretreatment needs.
Scheduled daily use
Schools & public facilities
Consider operating hours, term-time changes and available maintenance support.
BEFORE YOU ORDER
Questions worth
settling early.
What treatment capacity is available?
YHWJ-A is configured to the project requirements. Send your daily and peak flow; capacity, dimensions and equipment selection are confirmed in the technical proposal.
Can you guarantee a particular effluent standard?
The project-specific effluent targets and acceptance conditions must be agreed against influent quality, loading, temperature and operation. This page does not state a universal discharge guarantee.
Does the system include disinfection?
Disinfection is confirmed as part of the project scope where required. Do not assume it is included without the agreed equipment and process schedule.
How is the carbon-steel shell protected?
The coating or lining system, surface preparation, repair requirements and inspection method must be agreed for the soil, groundwater and installation conditions.
What maintenance and commissioning are needed?
Routine inspection, equipment servicing and sludge management requirements are set by the final configuration. Confirm installation guidance, biological start-up, operator training and commissioning responsibilities in the quotation.
When can the equipment be delivered?
Dispatch timing is confirmed after the design, scope and agreed payment conditions are settled. Shipping, installation and commissioning periods are considered separately.
