Our Services

SR Thaami Engitech provides structured, calculation-driven engineering consultancy for wastewater treatment projects.
We focus exclusively on process design, DPR preparation and technical documentation support.

Sewage Treatment Plant (STP) Process Design

Expert design of sewage treatment processes including SBR, MBBR, and MBR technologies.

We provide comprehensive sewage treatment plant process design support for residential, commercial and institutional projects.

Our STP design scope includes:

  • Wastewater flow estimation (average & peak)

  • Hydraulic calculations

  • Organic load (BOD/COD) analysis

  • Biological process design (SBR / MBBR / ASP)

  • Tank sizing calculations

  • Aeration requirement estimation

  • Sludge generation and handling strategy

  • Treated water reuse planning (non-RO scope)

  • Process Flow Diagram (PFD)

  • Design basis documentation

Each STP is designed based on project-specific load conditions — not generic templates.

Effluent Treatment Plant (ETP) Process Design

Industrial wastewater varies significantly in characteristics and load.
Our ETP design approach is tailored to industry-specific effluent profiles.

Our ETP design services include:

  • Effluent characterization study review

  • Equalization tank design

  • Neutralization system design

  • Primary treatment planning

  • Biological treatment system design

  • Chemical dosing calculation

  • Sludge thickening and handling design

  • Hydraulic and retention time calculations

  • Structured process justification notes

  • Process Flow Diagram (PFD)

We focus on technically justified, compliance-oriented and execution-friendly process design.

Well-structured documentation is critical for approvals and project clarity.

We prepare:

  • Detailed Project Reports (DPR)

  • Design Basis Reports

  • Process write-ups

  • Structured calculation sheets

  • Technology justification notes

  • Compliance-oriented documentation support

Our documentation supports:

  • Pollution Control Board submissions

  • Internal technical approvals

  • Tender documentation requirements

Each DPR is structured, calculation-backed and professionally formatted.

Water Treatment Plant (WTP) Process Design

Our focus is on delivering technically optimized and operationally simple systems.

Our scope includes:

  • Raw water quality assessment (Borewell / Surface / Municipal source)

  • Process scheme finalization

  • Clarification & Filtration system design

  • Softening / Iron Removal systems

  • Pre-treatment for RO systems

  • Disinfection system design

  • Hydraulic calculations & equipment sizing

  • PFD preparation and technical specifications

We ensure consistent treated water quality while optimizing capital and operational costs, with provision for future expansion.

Optimization & Upgradation Consultancy

Apart from new plant designs, we also provide technical review and optimization services for existing STP, ETP, and WTP systems.

Our Support includes:

  • Performance evaluation of existing plants

  • Capacity verification vs. actual load

  • Process bottleneck identification

  • Energy & chemical consumption analysis

  • Troubleshooting recurring operational issues

  • Upgradation & retrofit design

  • Compliance gap assessment

Our objective is to improve plant efficiency, reduce operational cost, and enhance long-term performance without unnecessary capital expenditure.
