Which process is right for my STP: MBBR, SBR or MBR?

It depends on inlet load, available footprint and the discharge or reuse standard you must meet. We recommend a process after a site survey and water analysis, and show you the trade-offs in cost, area and running power.

What is Zero Liquid Discharge (ZLD)?

A ZLD plant recovers almost all of the water from industrial effluent so that no liquid waste leaves the site. Treated water goes back into your process, and the remaining salts are separated out as solids for safe disposal.

What capacities do you handle?

From compact packaged units for single buildings to large plants for townships, municipalities and industry. Share your flow, water quality and site details and we will size the plant for you.

Can you take over O&M of a plant someone else built?

Yes. We audit the plant first, fix what is holding it back, then run it under an O&M or AMC contract with operators, preventive maintenance and compliance reporting.

How does online monitoring (OEMS) report to the regulator?

Analysers at the outlet measure parameters such as pH, BOD, COD and TSS continuously. The data is logged and shared with the pollution control board in the format your consent requires, and you see the same live data and alarms on your dashboard.
