SMART RAINWATER MANAGEMENT

Water resources can be used efficiently, and it is a measure to not only address water shortages but also prevent floods and create an eco-friendly environment. We seek to reduce costs by recycling rainwater for firefighting, landscaping, toilets, and cleaning purposes.

Roof surface / Water collection area

Initial rainwater Exclusion Device

Rainwater reservoir

Filter tank

Roof surface / water collection area : Transfer of initial rainwater to the rainwater tank
Initial rainwater exclusion device: Removal of initial rainwater contaminants
Rainwater reservoir : Highly polluted initial rainwater is discharged into the sewage pipe through an intelligent pump, and rainwater with low pollution is recycled through a filtration tank
Filtration tank : Removes general bacteria, E. coli, etc. through ceramic filter and UV filter.

Main control items

Rainwater reservoir level monitoring and pump operation control
Monitoring various filter conditions
Monitoring the status of pollutant filtration equipment
Send issues and data to operator

Main control items

Smart sewage treatment plant monitoring
Monitoring the quantity of sewer pipe passages and predicting flood damage
Monitoring sewer passage odor
Establishment of DB for maintenance of sewer pipe passage facilities
Send issues and data to operator

SMART WWT MANAGEMENT

To prevent the risk of flooding, efficiently collect and recycle the maximum amount of water, and also prevent hazardous substances from being discharged into the environment. Energy production using recycled energy

Wastewater treatment process

Waste water → Screening → Sump -> PH Balancing tank → Reaction tank → Coagulant tank → Settling tank → Aeration tank → Post-processing facility → Discharge and Reuse
Solid disposal → Mixing tank → Thickener → Anaerobic digestion → Centrifuge → Recycling
Gas recycling → Boiler →Use Hot-water supply

Main control items

Monitoring of WWT
Optimization of processes and chemical dosing for saving operating costs
Immediate action in case of equipment malfunction and discharge of treated water below standards
Send issues and data to operator

Water leak monitoring system

The existing method of inspection by a person using equipment required a skilled technician, which required time and high cost. By using a water leak sensor, continuous water leak monitoring and remote meter reading can be used to detect water leaks and dramatically reduce the amount of water leaks, thereby ensuring convenience and economic efficiency.

Water leak sensor (IoT)

LTE, LTE-M, LORA, NB-IoTInternet server communication

Management department Monitoring (PC, Mobile monitoring)

Water leak sensor detects water leak sound propagation

Surrounding sensors monitor water leaks and generate an alarm when water leaks occur

Expectation effectiveness

Minimize leakage losses through early detection of water leaks
Advanced prevention by identifying the frequency of water leaks
Maximize efficiency by identifying water leak points in real time

Air quality monitoring system

Air quality monitoring

Air quality measurement using in/outdoor air quality measurement sensors
Determine operation mode based on measured in/outdoor air quality
Automatic linkage control of air conditioners and air purifiers based on data storage and analysis

Expectation effectiveness

Create a pleasant internal environment by measuring air quality
Energy savings by linking air conditioner and air purification system
Providing air quality information to residents

Air curtain system

It is to use the force of air to block the external and internal air and prevent the entry of dust and small insects such as bugs in the air, and to maintain the temperature between the indoor and outdoor and maintain a pleasant indoor environment economically.

Expectation effectiveness

You can prevent children’s finger injuries by keeping the door open at all times
The circulation of indoor air by the wave of air curtain increases the efficiency of cooling/heating in a large indoor space
The energy saving effect occurs due to the increased efficiency of cooling/heating
By blocking the inflow of dust, vehicle dust, smoke, odor, etc. from the outside, a pleasant indoor environment is maintained

One-Pass system

Open all entrance doors with one <one-pass key (Mobile)>

Automatic OPEN of parking barrier

When a resident’s vehicle arrives at the parking lot entrance, the parking control system recognizes the one-pass key and opens the barrier

Automatic OPEN of household entrance door

When a resident arrives at the public entrance, the integrated control system recognizes the one-pass key and opens the public entrance door.

Automatic CALL of elevator

When a resident passes through the public entrance, the elevator is automatically called and the residential floor is automatically selected when boarding the elevator.

Automatic OPEN of door lock

When a resident arrives at the front door, the door lock recognizes the one-pass key and opens the door lock.

Transparent solar power generation system

The sunlight is converted into electric energy by the solar cell, and then it goes through the junction box to the inverter, where the direct current is converted into the alternating current that we use. This provides the domestic power supply inside the building.

Expectation effectiveness

Using transparent solar cells with excellent visibility (transmittance, color rendering) to install in areas where conventional solar cells cannot access
Saving costs by producing electricity by themselves
No need for re-investment other than initial investment cost due to semi-permanent life
Preventing various environmental problems because there is no fuel cost and no emission of pollutants such as carbon monoxide and industrial waste, as clean energy is used as the raw material for power generation

HEAT RECOVERY VENTILATOR SYSTEM

To exhaust the indoor polluted air to the outside and force the fresh outdoor air into the inside, a heat exchange system is used to exchange the temperature between the indoor and outdoor air, minimize the heat loss, and achieve the emission of pollutants (carbon dioxide, carbon monoxide, radon, gas, etc.) and energy saving.

Expectation effectiveness

Preserving indoor temperature during ventilation: Minimizing the change of indoor temperature due to ventilation with more than 70% heat recovery rate
Reducing cooling/heating costs: Saving more than 25% of energy costs compared to natural ventilation
Ventilation effect: Preventing the inflow of indoor harmful substances by purifying the pollutants with excellent filtering ability and supplying fresh air and exhausting polluted indoor air with a bidirectional forced ventilation method that separates exhaust and supply
Supplementing the disadvantages of air purifier: Removing harmful substances such as CO2, radon gas, etc.
