SSI designs and builds treatment systems for industrial wastewater, process water and landfill leachate — from pre-treatment ahead of a sewer discharge to complete treatment plants. Depending on the site, flow and schedule, we deliver either turnkey modular systems or full-scale plants installed on site.
Two ways to implement
Turnkey modular systems
- Process modules built in skids or modified shipping containers
- Fully integrated and factory wet-tested before shipping
- Plug-and-play: set, connect and start
- Minimal field work and a shorter schedule
Full-scale on-site implementation
- Complete plants inside a new or existing building
- Clarifiers, filter presses, tanks, piping and controls
- SSI-managed installation, start-up and operator training
- One team from design through commissioning
Treatment processes
pH & chemical conditioning
Acid/caustic neutralization, flash mix and flocculation with ferric and polymer feed.
Clarification
Inclined plate (lamella) clarifiers for solids removal.
Solids dewatering
Plate-and-frame filter presses and sludge handling.
Filtration & carbon
Automatic-backwash multimedia filters, bag, cartridge and carbon polishing.
Ion exchange
Selective resin systems, such as boron removal, with automated backflush and regeneration.
VOC & metals removal
Project spotlight: boron & metals removal
For a groundwater remediation project, SSI supplied a complete skid-based plant to remove boron and metals from water pumped from 28 extraction wells. Every skid arrived fully plumbed and pre-wired with its own PLC control panel, keeping field integration to a minimum.
- Well field28 well pumps on networked VFDs; manifold with a flow meter on every well
- Aeration & pHAerated inlet tank with pH monitoring
- ClarificationStainless clarifier with flash mix and flocculation chambers
- FiltrationFour multimedia sand filters with automatic backwash
- Boron resinResin vessels with pH and conductivity monitoring and automated backflush
- Solids & residualsRegeneration and disposal tanks, filter press dewatering
Hydrochloric acid, ferric chloride and sodium hydroxide are dosed from dedicated chemical feed skids. Each process skid has local hand-off-auto control and connects to a master control panel by a single Ethernet cable, so operators can monitor and run the whole plant from one screen — or remotely by telemetry.
Every system includes
- Chemical feed systems with secondary containment
- Level, flow, pH and pressure instrumentation
- UL 508A control panel with telemetry
- Start-up, operator training and O&M support
