Compliance Retrofits

Bring aging treatment facilities into compliance with evolving discharge standards. From nutrient removal and micropollutant control to odour management and emerging contaminant treatment, we design retrofits that meet regulatory requirements without rebuilding your plant.

How It Works

A structured approach that ensures consistent, high-quality results delivered on time and within budget.

1

Assessment

Evaluate current conditions, requirements, and identify opportunities.

2

Planning

Develop a detailed action plan with timelines and resource allocation.

3

Implementation

Execute the planned work with quality control and progress monitoring.

4

Validation

Verify results against objectives and provide ongoing support.

Core Services

Comprehensive expertise delivered by experienced engineers using industry-leading tools and methodologies.

Industries

Tightening discharge limits for nitrogen, phosphorus, micropollutants, and emerging contaminants are rendering many legacy treatment plants non-compliant. Regulatory deadlines are often short, and capex budgets constrained. We retrofit existing infrastructure to meet new limits without full rebuilds.

Equipment & Systems

Reynolds & Bauhm specialises in compliance-driven retrofits that integrate advanced treatment processes into existing layouts. Our designs prioritise compact footprints, modular installation, and minimal downtime during cutover.

Services

End-to-end retrofit services from process assessment and CFD validation through to equipment supply, installation, commissioning, and ongoing support. We work within existing plant footprints and operational constraints.

Tools & Calculators

Use our online calculators to estimate nutrient removal requirements, chemical dosing rates, and sludge production for compliance retrofits. Validate retrofit feasibility before committing capital.

Company

Reynolds & Bauhm has delivered compliance upgrades across municipal, industrial, and food & beverage sectors worldwide. Our engineers understand regulatory frameworks in the EU, UK, North America, Australia, and Asia.
