Flow & load assessment
Characterise current and future flows, pollutant loads, variability, industrial contributions and treatment objectives.

Viraya develops coordinated wastewater treatment solutions around actual influent conditions, required treated-water quality, operator needs and long-term performance.
Discuss your treatment project ↗Effective treatment starts with reliable wastewater data and a clear understanding of discharge, reuse, site and operating requirements.
Viraya develops treatment concepts and coordinated engineering around influent characteristics, applicable standards, site constraints, operator capability, energy demand and whole-life value. The scope can connect inlet works, equalisation, primary and biological treatment, advanced polishing, disinfection, sludge handling and supporting utilities.
Where suitable, we evaluate treated-water reuse and resource-recovery opportunities against required quality, process risk, operating complexity and economic context. Final process selection and performance criteria are established for the specific wastewater and regulatory environment.
Characterise current and future flows, pollutant loads, variability, industrial contributions and treatment objectives.
Coordinate screening, grit removal, pumping, equalisation, bypass philosophy and the plant hydraulic profile.
Evaluate suitable processes for organic-load reduction and required nutrient control under expected operating conditions.
Develop appropriate filtration, membrane and disinfection barriers where discharge or reuse requirements demand them.
Plan thickening, stabilisation, dewatering, storage and responsible onward handling, with recovery options where viable.
Define instrumentation, process control, testing, startup and performance-verification requirements.
Influent quality, applicable standards, reuse objectives, site footprint, energy and operator resources shape the treatment configuration.
Treatment planning for communities, urban districts and expanding public collection systems.
Targeted process evaluation for variable, concentrated or industry-specific wastewater characteristics.
Additional treatment barriers for suitable irrigation, landscape, industrial and other non-potable uses.
Compact, maintainable treatment solutions for developments, institutions and remote facilities.
We connect wastewater data, applicable requirements, process behaviour, site constraints and operator needs before defining the plant.
Establish wastewater sources, variability, future demand, required quality and potential reuse objectives.
Evaluate treatment trains against performance, energy, footprint, risk, cost drivers and operating complexity.
Integrate process, hydraulic, civil, structural, mechanical, electrical, control and site requirements.
Plan testing, biological startup, performance verification, training and operational-readiness activities.
