Water and wastewater

Every site is different. That’s why we develop and deliver modular water treatment and dewatering solutions that match your process, flow rates and environmental goals.

Solution that handle demanding conditions like in food processing, pulp and paper, mining operations and municipal plants. We help you reduce emissions, reuse water, recover nutrients and control costs — from piloting to full-scale operation.

With real-time monitoring and remote control, you stay informed and in control. Backed by case-proven results, we help you move from compliance to performance — step by step.

Processes and applications

Food and beverage industry

Modular cleantech for treating wastewater and recovering resources in food and beverage production.
  • Fish processing sites – solids removal and nutrient separation
  • Slaughterhouses – treatment of high-organic-load effluent
  • Dairy plants – separation of fats, proteins and residuals
  • Breweries and beverage lines – COD and BOD reduction

From nutrient recovery to safe discharge, our cleantech help you meet strict environmental requirements while saving energy and operational costs.

EXPLORE SOLUTIONS

Fiber industry

Solutions for managing process water and recovering fibers in pulp, paper and board production.
  • Pulp and paper mills – fiber recovery and primary sludge treatment
  • Plywood production – resin removal and effluent clarification
  • Board and packaging plants – reduction of suspended solids and COD
  • Emergency or bypass use – fast-deployable units for outages and seasonal peaks

From raw material processing to final product rinsing, our systems help reduce water use, meet strict discharge requirements and improve overall process reliability.

Mining industry

Scalable and modular units for treating water and recovering by-products in mining operations.
  • Process water treatment – solids separation and pH adjustment
  • Tailings water reuse – removal of suspended solids and contaminants
  • By-product recovery – extraction of metals and nutrients from sludge
  • Emergency or bypass use – mobile units for site maintenance or start-up phases

Our cleantech solutions are designed for demanding site conditions and are easily relocatable or scalable. We help you comply with environmental regulations while improving circular water use and operational continuity.

 

Municipal wastewater treatment

Flexible treatment and sludge handling for municipal sites, from decentral plants to emergency use.
  • Pre-treatment of industrial discharges – tailored for sectors like food and beverage
  • Decentralized treatment units – for villages, resorts, and temporary settlements
  • Sludge dewatering – reduce transport and disposal costs
  • Emergency or bypass use – fast setup during upgrades, floods or plant downtime

Our containerized systems are quick to deploy, easy to operate and designed to meet environmental regulations reliably — with or without permanent infrastructure.

Other applications

Through Sulzer and trusted partners, we deliver complete water and wastewater solutions — from pumping and aeration to advanced treatment and automation. Integrated capabilities include applications like:

  • Pumps and mixers – for clean and wastewater
  • Construction sites – rental-ready water treatment tailored to your project
  • Environmental incidents – dredging and water treatment for contaminated areas
  • Emergency and bypass use – ideal for floodwater management or plant maintenance

Together, we build solutions that scale with your needs — supporting long-term performance, safety and sustainability.
