Premium

Finished like equipment, not like civil work.

A conventional plant is poured, plastered and patched together on your site. PromaX is made the way fine equipment is made: in our own works, in stainless steel, with every pump, blower and panel fitted and finished before it leaves.

Capacity per unit: 5 – 500 KLD
Process: MBBR · Hybrid MBBR · MBR
Controls: MCC with PLC / HMI
Housing: Stainless steel
Made in: Vapi, India

Aesthetic

Most treatment plants are hidden behind a wall. PromaX is built to stand in plain sight.

Clean lines, one enclosed unit and no open tanks, so the plant can sit where it is needed: beside villas, guest rooms, offices and workshops, rather than fenced off at the far end of the site.

Set beside the building it serves
Designed to be seen, not screened

High performance

Treated water to your standard, measured by an independent laboratory.

Each PromaX is sized for your load and for the standard your treated water must meet, whether it is discharged or reused. The process is chosen for the job, not fixed by the box.

Typical design values for domestic sewage. The MBBR outlet includes settling and tertiary filtration; * total nitrogen below 10 mg/L is met with an anoxic stage. A grease trap ahead of the plant is part of every design. India limit: National Green Tribunal order of 30 April 2019 for sewage treatment plants. Each PromaX is designed to its own inlet and site standard, and its outlet is tested by an independent laboratory; a copy of the report is available on request.

Compact

The whole plant, in one housing.

Treatment, equipment room and controls share a single unit on a single plinth. It is built in our works, lifted out in one piece and set down ready for connection: a small footprint for the flow it treats.

The range

One design, every size.

From a compact skid to a full container housing, every PromaX is built to the same finish.

Odour-free

Enclosed from inlet to outlet.

No open tanks and no open water surfaces, so there is no smell where people live, stay and work. That is why PromaX stands on island resorts, where guests are never far from the plant.

No open tanks
No smell beside villas and guest rooms
