- Any application where further polishing of treated, reclaimed, recycled or reuse water is desired
- Typically installed following a treatment process and secondary treated water with a BOD/TSS of 20/30 or better
- Applications including municipally-treated effluent designated for irrigation or discharge into receiving waters where permitted
- For batch or continuous treatment systems
- Optional models offer:
- Flocculation
- Chlorine dosing
- Free chlorine monitoring
- Turbidity monitoring and management
 |
- SewaClear’s ability to “polish” 20/30 level secondary-treated effluent to 5/5 means less pollution in lakes, streams and other receiving bodies
- Meets California’s Title 22 Water Reuse requirements (when using the flocculation option)
- Complete pre-filtration and main filtration as well as optional disinfection, turbidity management and/or flocculation are available in one complete, small footprint package making installation fast and easy
- Ability to operate up to 24 hours a day means treatment can be continuous
- High quality components ensure reliability and low operating costs
- 110VAC single phase power requirement makes hook-up easy
- Three layers of media in each media tank remove organic and inorganic particles from water as well as more expensive and complex membrane systems
- Siemens PLC (Programmable Logic Controller) provides complete control in all operating modes without the need for further interface
- Control system flexibility means SewaClear can be wired to other control systems if unified project control is required
- PLC allows for remote system monitoring (other components may be required)
- Flow rates through the filters of less than 5 GPM per square foot allow for high surface-area-to-flow cleaning
- Isolation valves on each tank allow media to be replaced without shutting the entire unit down
- Filter backwash process uses filtered water from other filters in-line
- Filter backwash flow rates do not exceed system flow rates (except 6 GPM model), eliminating the need for separate hydraulic connections or calculations
- Short cleaning cycles minimize downstream flow interruptions
- All components are weather-proof making protective covering optional (normal winterizing precautions must be taken in freezing conditions)
- Optional flocculation process allows for the capture of microscopic particles in the water, ensuring more particles are captured and filtered out of the water
- Optional disinfection by chlorine/hypochlorite gas solution further purifies the water
- Optional turbidity management allows the user to set clarity requirements for the water without the need for additional systems downstream
- Use of optional flocculants such as alum help manage phosphorus/phosphate

| Standard System Functions |
Takes place in an automatic, self-cleaning screen filter.
Performed by an array of four multi-media filters with 3 layers of materials in a high-depth media bed for exceptional effluent polish at low filtration rates.
Controlled by a Siemens PLC which manages all aspects of the filtration and backwash processes. Backwashes are performed automatically by pressure or at preset intervals.
|
- Provides primary filtration of incoming water
- Removes any coarse materials from the water
- 200 micron screen (80 mesh)
- High depth media bed
- Four filters - each contains three layers of material
- Flow rates < 5 GPM per square feet for thorough filtration
- Made of carbon steel
- All steel parts have a 100 micron protective coating of extra durable polyester protection, applied electrostatically on a zinc-phosphate base coat and oven cured for maximum anti-corrosion protection.
Controlled by a Siemens PLC which manages all aspects of the filtration and backwash processes. Backwashes are performed automatically by pressure or at pre-set intervals. |
