Unmanned automatic controlled initial stormwater treatment facility
WATERON-INT (Wateron-Innovative Non point source Treatment)

1. Overview
◦ This system treats the rainfall containing high-concentration non-point contaminant initially through the screen and then treats the stormwater through the filter media mounted inside the filtration tank, and can be maintained by unmanned automatic control after operation is completed.

2. Key technologies
◦ Automatic maintenance system implementation after rainfall
- Automatic stagnation water discharge and filter media backwashing system (air cleaning +  water washing)
◦ Washing water can be reused for backwashing
- No need to use tap water because the treated water cab be recycled

3. Sequence of treatment
◦ Inflow → Gravitational sedimentation → Screen filtration  → Filter filtration → Detention  → Discharge

4. Applications
◦ Large-scale housing land development district
◦ River refurbishment and agriculture/industrial complexes
◦ Excellent stormwater treatment in the merging type stormwater pipe culvert
◦ Industrial complexes, logistics complexes
◦ Factory and commercial areas
◦ Excellent stormwater treatment in the separation type stormwater pipe culvert

5. Features
◦ Excellent treatment efficiency based on screen filtration, gravity sedimentation and secondart filter filtration
◦ With upstream filtration system and cleaning system, the facility performance can be maintained without clogging the filter media

◦ Minimization of manpower during maintenance with automatic maintenance system after rainfall
◦ Adjustable filler ration enables stable response to the quality of influent, ensuring stable tratment
◦ Low maintenance cost due to reuse of treated water

6. Automatic maintenance datails
◦ Stagnant water discharge system──▶Automatic discharge of stagnant water keeps the plant dry
◦ Air cleaning system ──▶ Air blower operated simultaneuusly with stagnant water discharge to disturb the filter media
◦ Water washing system ──▶ Downstream water washing using the treated water within treatment water tank
