Wastewater treatment is complicated and risky. Make it straightforward and safe.

So much can go wrong in the delicate process of wastewater treatment. Even when everything goes right, interdependent steps and components still need to be closely monitored and controlled. XiO Systems are complete, tailored, and secure designed for the high risk, high cost and laborious process of wastewater management.

  • Avoid expensive EPA fines and untimely hardware replacements.
  • Harness sophisticated peripheral control
  • Equalize high-level flow (surges, pump failures, etc.) to react quickly to system changes

Select from our list of robust turnkey solutions or design XiO into each phase of your unique treatment process.

Treatment Solutions

While wastewater treatment systems have much variability in size and approach, XiO offers solutions for each step in the process. Let’s walk through a standard sequence, which can be reconfigured according to your needs.

Read about XiO’s unique design process.

The headworks is the central point for incoming wastewater flow. XiO systems measure and report the flow rate in the Parshall flume so you can make control adjustments to the system when a surge occurs. Every wastewater system is built to withstand surges, but influent flow varies significantly throughout the day and seasons. Thus, if you’re not adjusting your controls processes responsively, you’re risking an EPA disaster, wasting energy, letting necessary bacteria die, or ruining machinery. XiO systems automate adjustments for you by assessing this real-time flow rate.

XiO monitors your screening process when solids are filtered out, so that water is flowing at a steady pace and there aren’t any clogs or overflows. XiO monitors your screening process to monitor upstream and downstream levels with ultrasonic, submersible, or radar level sensors. Cloud SCADA® logs screen runtime and frequency and generates alarms if these exceed values set by the operator. With simple, easy to understand graphing tools, the operator can easily view the operation of their wastewater headworks.

Wastewater often flows through a flocculation and sedimentation process where the solid matter in the liquid group together to more easily separate from the liquid. Over time, these groups of particles, or “flocks,” settle to the bottom of the sedimentation basin or clarifier. This process makes it easier to remove solids from the wastewater and ensures the efficiency of downstream operations.

After screening, the wastewater moves into a bacteriological process, which may include both aerobic and anaerobic digestion in various sequences. Aerobic digestion happens an aeration basin (or lagoon) where blowers keep sanitizing bacteria alive by feeding them the right amount of oxygen. Anaerobic digesters starve harmful bacteria of oxygen. In a process called cogeneration, the CO₂ biogas resulting from anaerobic digestion can be used to provide substantial power to plants. Treatment facilities may repeat bacteriological procedures after the clarification process to ensure that waste is properly sanitized and maximally recycled.

XiO can provide sensors or integrate with your existing sensors (4-20mA) to closely monitor dissolved oxygen (DO). Furthermore, XiO Pump Control and Variable Frequency Drive (VFD) Control automatically respond to your DO setpoints. XiO automates DO level control so that the proper sanitizing bacteria thrive. XiO systems perform simple functions like turning pumps on or off or running pumps at varying frequencies to deliver energy-efficient and precise control of oxygen levels. This functionality ensures optimal conditions for the good bacteria and saves your pumps from harsh starts and stops. It’s like cruise control for your pump to match the biological or biochemical oxygen demand (BOD).

The sweeper in the clarifier rotates to separate the “mixed liquor,” creating three distinct layers: scum, liquid, and sludge. Without sweepers, mixed liquor won’t separate, and scum and sludge are impossible to measure correctly. Although weir gates maintain liquid levels, storm and flood surges can still challenge this part of the system. Despite large influxes of water, XiO maintains the optimal scum-liquid-sludge ratios in your clarifier by controlling pumps for WAS (Waste Activated Sludge) and RAS (Returning Activated Sludge). XiO technology monitors the sweeper motor(s) for failure and alarms notify operators.

XiO Cloud SCADA measures & monitors the scum and sludge levels, which must remain constant to maintain the health of good bacteria and suppress the growth of unwanted bacteria, and then, to keep this balance, XiO controls pumps. These pumps send the excess scum, and sludge blanket one of two placed: recirculate a percentage of back into bacteriological digestion as RAS, or after materials have undergone “thickening,” pumps send it into drying beds as WAS. The product of these drying beds may end up as fertilizer at your local garden store.

Pumps send a certain percentage of WAS from the clarifier to sand filters. XiO Cloud SCADA® Control Systems give you the simple ability to change filter parameters and tune filter backwash cycles. As environmental conditions change, you can adjust limits and levels to accommodate variables in wastewater treatment.

Filter media tends to plug over time, often in uneven ways due to the irregular distribution of fats, oils, and grease (FOG) or solids to different filter chambers. XiO backwashes individual filter chambers that demonstrate symptoms of clogging media, like increasing liquid levels over the media.

Pumps also send a certain percentage of the WAS from the clarifier to chemical reactors for chlorine injection. XiO systems precisely monitor chemical tank levels and control the chemical dosage, or pump pacing, based on flow-rate, residual chlorine, and operator input.

After the chemical treatment of the liquid, the residual solids move to drying beds, and the processed water moves to ponds or lagoons for discharge. XiO monitors and reports lagoon levels and controls the discharge pump(s) to complete the water treatment process safely.
