Process engineering for industrial wastewater and waste-to-value projects

Puran Water. We work with project developers, EPC contractors, and plant owners on the design decisions that drive lifecycle cost.

We do process engineering for industrial wastewater and waste-to-value projects. Every design decision is evaluated on lifecycle cost: capex, opex, and the downstream consequences three or five years out.

Conceptual Design

Process engineering ideation

We develop process designs that meet the project's objectives at low life-cycle cost while keeping technical performance risk in check. Our experience covers projects with strict discharge standards (including Zero-Liquid-Discharge) and projects that generate revenue from resource recovery — biogas, wastewater reclamation, organic fertilizer. That breadth lets us evaluate treatment options quickly and put a custom design on paper that fits the constraints.

Project feasibility studies

We run feasibility studies that quantify the economic and operational impact of a project before significant capital is committed. For discharge-driven projects, we evaluate the CAPEX and OPEX impact on the industrial discharger. For owner/operator waste-to-value projects, we model how variations in project inputs and process design shift levered IRR, DSCR, and the other indicators that lenders and equity investors actually use to decide.

Process Engineering

Process engineering packages

We produce process engineering packages that include PFDs, P&IDs, mass and energy balances, equipment datasheets, control narratives, and concept construction drawings. That package gives an MEP, civil, and structural engineering team enough to develop issued-for-construction plans and specifications. It gives procurement teams enough to solicit pricing and purchase equipment. And it gives panel shops the detail they need to design, build, and program control systems.

Process design review

Using our own expertise and our network of technology suppliers and specialized consultants, we review process designs to identify opportunities for reducing performance risks and improving project economics. A design review is often the highest-ROI engagement we do — second opinions tend to surface issues while the cost of changing direction is still low.

Technology Supply

Technology and critical equipment supply

Through licensing agreements and knowledge of the supplier landscape, we have access to proprietary waste-to-energy and zero-liquid-discharge technologies. That access lets us deliver both the process engineering package and the critical equipment package on projects where the proprietary technology is the right fit — sized and specified together rather than stitched from two vendors with different assumptions.

Process Optimization

Process modeling

Our in-house capability covers biological treatment processes and most of the common industrial wastewater unit operations. That lets us simulate the impact of process setpoint changes or design modifications in model space, before incurring implementation costs.

Capacity expansion and new treatment objectives

Unlike equipment vendors, we are not paid to push unnecessary capital expenditures. We use the modeling capability to find capacity in existing assets when load increases or discharge limits tighten. When expansion is unavoidable, the recommendation is shaped to the actual capacity or quality shortfall — the smallest cost-effective addition that closes the gap.
