ETP Feasibility Report Consultant for Industrial Wastewater Treatment Projects

SARK Engineers & Consultants prepares engineering-led ETP feasibility reports for industrial wastewater treatment projects, including new ETP installations, plant expansions, CTE/CTO planning, treatment upgrades, vendor proposal comparison, wastewater reuse and ZLD-linked projects.

An ETP feasibility study should establish whether the proposed treatment system is technically practical for the actual wastewater quantity, pollutant load, treatment objective, site constraints and compliance requirements before major capital expenditure is committed.

The review may cover wastewater source mapping, hydraulic load, BOD, COD, TSS, TDS, pH, treatment route, reuse potential, sludge handling, utility demand, space requirement and linkage with RO, MEE, MVR or other ZLD systems where relevant.

What Is an ETP Feasibility Report?

An ETP feasibility report evaluates whether a proposed Effluent Treatment Plant is technically suitable for the wastewater generated by an industrial facility and whether the proposed treatment approach can realistically support the required discharge, reuse or compliance objective.

It is different from simply obtaining an ETP quotation.

A vendor quotation normally proposes equipment.

A feasibility study should first determine:

  • what wastewater is being generated;

  • how much wastewater is generated;

  • how flow varies during the day or batch cycle;

  • what pollutants are present;

  • which streams should be segregated;

  • what outlet quality is required;

  • whether reuse is technically possible;

  • whether ZLD is relevant;

  • what treatment route is appropriate;

  • what major utilities and space may be required.

The purpose is to create a credible engineering basis before treatment technology and vendors are finalised. This is consistent with the current page’s “Answer First” positioning and feasibility methodology.

When Should an Industry Prepare an ETP Feasibility Report?

New ETP Installation

For a new industrial project where wastewater quantity, characteristics, treatment route, site area and utilities still need to be established.

CTE / CTO Planning

Where pollution-control documentation requires realistic assumptions regarding:

  • water consumption;

  • wastewater generation;

  • treatment capacity;

  • discharge;

  • reuse.

Production Expansion

When increased production, new products or process changes may increase:

  • hydraulic load;

  • COD/BOD load;

  • TDS;

  • chemical load;

  • sludge generation.

​ETP Upgrade or Augmentation

Where an existing plant is:

  • overloaded;

  • unstable;

  • unable to meet outlet norms;

  • facing higher production load;

  • requiring reuse or ZLD integration.

Treatment Technology Selection Should Follow Wastewater Characterisation

The treatment technology should be selected only after understanding the wastewater.

Depending on industry and wastewater quality, a treatment route may involve:

  • equalisation;

  • pH correction;

  • coagulation and flocculation;

  • clarification;

  • biological treatment;

  • filtration;

  • activated carbon;

  • disinfection;

  • ultrafiltration;

  • reverse osmosis;

  • evaporation;

  • crystallisation.

Frequently Asked Questions

What is an ETP feasibility report?

An ETP feasibility report assesses whether a proposed effluent treatment system is technically suitable for the wastewater quantity, quality, treatment target and compliance requirements of an industrial facility.

 

When should an industry prepare an ETP feasibility report?

Ideally before new ETP installation, vendor finalisation, production expansion, CTE/CTO planning, major wastewater-treatment investment or ZLD evaluation.

 

What data is required for ETP feasibility?

Typical inputs include production capacity, process details, water consumption, wastewater quantity, BOD, COD, TSS, TDS, pH, relevant contaminants, consent conditions and available vendor proposals.

 

Is an ETP feasibility report the same as ETP design?

No. Feasibility establishes the preferred treatment direction and design basis. Detailed engineering follows with hydraulic sizing, equipment, civil works, layout, piping and instrumentation.

 

Can ETP feasibility help compare vendor quotations?

Yes. Vendor proposals can be compared on design basis, treatment route, equipment scope, utilities, sludge handling, recovery assumptions, exclusions and performance guarantees.

 

Can an existing ETP be augmented instead of replaced?

Often yes. The feasibility assessment should determine whether existing civil structures and equipment can be retained, upgraded or supplemented before recommending complete replacement.
