Hy-Series

Wastewater Treatment Plants

Compact, plug-and-play biological treatment. Hy-Series plants use extended aeration with return sludge for dependable residential wastewater treatment and straightforward long-term support.

One proven platform

Built for domestic wastewater. Flexible for the site.

Hy-Series is Hy-Treat’s standard plug-and-play platform for villas, residential buildings, compounds, and other facilities producing domestic-type wastewater. Each plant combines biological treatment, clarification, sludge return, and automatic operation in a compact fabricated system.

Suitable applications

A practical treatment route when no reliable sewer connection is available.

01

Villas

Compact treatment for permanent homes, seasonal residences, and properties replacing septic storage.

02

Residential buildings

Plants sized around occupancy, daily flow, peak use, and available installation space.

03

Compounds

Modular capacity and flexible layouts for grouped residences and phased development.

04

Small facilities

Assessment for domestic-type wastewater from suitable light-commercial applications.

Why Hy-Series

Treatment engineered as a complete operating system.

A / BIOLOGY

Actual aerobic treatment

Continuous oxygen supports the microorganisms that reduce organic pollution before the water reaches clarification.

B / FABRICATION

Compact polypropylene body

A self-supporting fabricated plant designed for transport, excavation placement, connection, and service access.

C / SUPPORT

Service without brand dependence

Hy-Treat stocks practical replacement parts and supports the complete plant even when individual component suppliers change.

Provisional standard range

A standard range up to 16 m³/day.

Twelve standard capacities cover individual villas, residential buildings, and larger grouped applications. Final selection remains subject to hydraulic load, organic load, wastewater characteristics, and Hy-Treat engineering review.

The process stays proven. The project can still adapt.

Where site geometry, groundwater, loading, discharge conditions, future capacity, or access require a different arrangement, Hy-Treat can modify the physical design or develop a custom system around the project’s real constraints.

Optional polishing can include filtration, disinfection, monitoring, and treated-water reuse equipment where the required water quality and local conditions allow.
