Biological treatment is the core of most water and wastewater plants. We represent proven, field-tested biological technologies engineered for reliable, compliant, energy-efficient operation across municipal and industrial applications.
Time-based activated sludge treatment in a single reactor
The Aqua SBR system runs fill, react, settle, and decant phases in one tank instead of a separate train of basins, which keeps the footprint tight and every component within reach for maintenance.
Because treatment is scheduled in time rather than spread across space, cycle timing can be adjusted as flow and load change — a good fit for plants with seasonal swings or high-strength industrial contributors.
Compact biomass, complete treatment in one aeration step
Aqua Nereda relies on aerobic granular biomass — dense, fast-settling granules rather than conventional floc — to complete BOD, nitrogen, and phosphorus removal in a single aeration step.
The granular biomass settles quickly and holds together under load, which lets the system run in a smaller footprint with lower aeration energy and chemical use than a comparable conventional activated sludge plant.
Pre-engineered biological capacity, delivered and connected
When a plant faces an overload, an equipment failure, or a gap while permanent upgrades are under construction, skid or trailer-mounted rental biological systems provide certified treatment capacity without waiting on a capital project.
PLZ Water Tech can scope, deliver, and support a rental biological package sized to your permitted flow and effluent target.
Rental biological systems keep a plant in compliance during an overload, an equipment failure, or a construction sequencing gap — delivered, connected, and supported by our team.
From a single piece of replacement equipment to a full plant process flow, PLZ Water Tech works alongside your team to design, size, and source the right technology.
