Stop waiting years for centralized civil infrastructure. We deliver 100% plug-and-play, containerized Ultrafiltration (UF) and Packaged STP architectures designed for rapid deployment in rural communities and disaster relief zones.
We architect decentralized, budget-optimized water cycles for public infrastructure.
Converting highly turbid river or lake water into safe, pathogen-free WHO drinking water for rural villages.
Treating decentralized domestic wastewater to prevent groundwater contamination and meet local EPA discharge limits.
Rapid-deployment mobile water stations for refugee camps or natural disaster zones lacking grid power.
Municipal budgets are tight, and rural communities lack specialized engineers. Centralized mega-plants are often unviable. Here is the deep-dive into how WANDONG ENVIRO architects around the three deadliest public sector constraints.
Traditional municipal water treatment relies on massive, centralized concrete plants. This requires years of planning, millions in CapEx, and laying miles of expensive underground piping to reach remote villages. For developing nations or rapidly expanding suburbs, this timeline leaves communities without safe water for years.
The Engineered Cure: WANDONG ENVIRO champions Decentralized, Containerized Architecture. We shrink a municipal water plant into a standard 40HQ shipping container. By deploying multiple decentralized units directly at the point of need (villages, camps), we eliminate the need for extensive piping networks and collapse the deployment timeline from 3 years to 60 days.
Advanced water treatment systems (like RO or MBR) are highly sensitive. In rural municipalities or NGO camps, it is impossible to staff PhD-level process engineers 24/7. When complex systems are handed over to untrained local operators, membranes foul, pumps run dry, and the multi-million dollar asset is abandoned within months.
The Engineered Cure: We engineer for "Idiot-Proof" Automation. Our Siemens PLC systems feature one-button start/stop logic. Complex processes like Ultrafiltration (UF) backwashing, chemical dosing, and sludge recirculation are 100% automated. We utilize robust, low-maintenance technologies (like AO/A2O biological processes) that don't require daily tweaking, ensuring the plant survives long after our commissioning team leaves.
Rural surface water (rivers, lakes) is highly unpredictable. During monsoon seasons, turbidity can spike from 10 NTU to over 1,000 NTU overnight, carrying massive loads of suspended solids, E. coli, and cholera pathogens. Standard sand filters cannot handle these spikes, leading to disease outbreaks in the community.
The Engineered Cure: We bypass outdated sand filtration and deploy Pressurized Ultrafiltration (UF) Modules as the core barrier. With a pore size of 0.01μm, our PVDF hollow-fiber membranes act as an absolute physical barrier, rejecting 99.99% of bacteria and viruses, regardless of how muddy the river gets. The output is consistently crystal-clear water (< 0.1 NTU) ready for safe consumption.
A direct Total Cost of Ownership (TCO) comparison for a standard 1,000 m³/day community water plant. Eliminate the "Piping Tax".
We utilize a standardized, field-tested Ultrafiltration (UF) block flow that guarantees pathogen-free water from the most turbid rivers.
Absolute physical barrier. Rejects 99.99% of bacteria, viruses, and colloids.
Gravity-fed WHO-grade water to village tap stands.
Raw surface water must comply with the following parameters. Exceeding these limits requires additional settling basins or chemical coagulation.
| PARAMETER | MAX LIMIT (UF FEED) |
|---|---|
| Turbidity (NTU) | < 1000 NTU |
| TSS (Suspended Solids) | < 100 mg/L |
| Oil & Grease | < 2 mg/L |
| pH Range | 2 - 11 |
When inlet conditions are met, WANDONG ENVIRO contractually guarantees the following WHO-compliant drinking water standards.
| OUTPUT METRIC | GUARANTEED VALUE |
|---|---|
| Product Turbidity | < 0.1 NTU |
| SDI₁₅ | < 2.5 |
| E. Coli / Coliforms | Non-Detectable |
| Virus Removal | > 4-Log (99.99%) |
You cannot deploy complex systems to remote villages and expect them to survive. Our PLC logic is designed to run autonomously, requiring only basic visual checks from local community operators.
Ultrafiltration (UF) membranes filter out massive amounts of mud and bacteria. If not cleaned properly, they block within days. We completely remove this responsibility from the local operator.
Our systems feature Fully Automated CEB (Chemically Enhanced Backwash). The PLC automatically reverses the water flow every 30-60 minutes, injecting a precise dose of sodium hypochlorite to scour the membrane pores and blast the accumulated mud out to the drain. The operator only needs to press a single green "START" button.
For NGO project managers sitting in capital cities, our IoT dashboard provides real-time visibility into village water plants. You receive SMS alerts if chemical tanks are running low or if there's a power failure, allowing you to dispatch maintenance teams only when truly necessary.
We adapt to NGO and municipal CapEx limits by offering premium Asian alternatives (e.g., CNP pumps, Vontron membranes) that deliver 100% of the performance at 60% of the cost.
Standardized for global ocean freight and rough-terrain inland trucking to remote villages.
| System Model | Capacity (m³/day) | Application | Shipping Format |
|---|---|---|---|
| WD-UF-100 | 100 m³/day (River Water) | Village Drinking Water | 1 × 20'GP Container |
| WD-RO-250 | 250 m³/day (Borehole) | Municipal Desalination | 1 × 40'HQ Container |
| WD-STP-50 | 50 m³/day (Sewage) | Community Sanitation | Packaged AO/A2O Tank |
