Modular wastewater treatment systems for municipal and industrial applications

Wastewater Treatment

WATER PLATFORM

Wastewater — municipal or industrial — carries the full complexity of human and production activity. Treatment is not optional: it is the critical step between process output and environmental compliance. Klarwin integrates modular, containerized treatment systems that deliver NTPA 001/2005 and NTPA 002/2005 compliance — with minimal footprint and reduced operational cost.

Reference projects in 50+ countries. German-manufactured systems with 20-year warranty. Plug-and-play installation without permanent infrastructure — relocatable, rentable, expandable.

Fixed Bed Bioreactor (FBBR) system for municipal wastewater treatment

Municipal Wastewater — Fixed Bed Bioreactor

Klarwin integrates Fixed Bed Bioreactor (FBBR) systems — certified by PIA GmbH — for municipal wastewater treatment at capacities from 10 to 5,000 m³/day. Lower CAPEX and OPEX than MBBR or MBR alternatives, with no chemicals required and no odor emissions.

Capacity: 10–5,000 m³/day, modular scaling
Treatment stages: pre-treatment, flow equalization, biological process, clarification, filtration, disinfection
Certified by PIA GmbH — independent European testing institution
Recommended by leading EU water associations
Above-ground or underground installation
Plug-and-play — no permanent infrastructure or construction required
Manufactured in Germany with full process and effluent guarantees

Industrial Wastewater — DAF & Process Treatment

Industrial wastewater requires treatment processes adapted to each application — from primary physico-chemical separation and conditioning, through secondary biological treatment and advanced tertiary polishing stages. Klarwin integrates Dissolved Air Flotation (DAF) systems with patented self-cleaning design, engineered for flows between 1 and 250 m³/h and separation efficiencies up to 99%.

Primary treatment — mechanical separation, DAF flotation, equalization and pH correction
Secondary treatment — aerobic/anaerobic biological processes, clarification and sedimentation
Tertiary treatment — nitrogen and phosphorus reduction, advanced filtration, UV disinfection and ozonation
DAF systems — capacities between 1–250 m³/h, high efficiency for reducing COD, BOD and FOG
Patented self-cleaning design — also available in two-stage DAF configurations
Construction materials — polypropylene and high-density polyethylene for high chemical resistance and durability
Long-term reliability — up to 20-year warranty for new systems purchased directly

DiOx Advanced Electrochemical Oxidation — diamond-coated electrode stack

Advanced Oxidation — DiOx AEOX Technology

For persistent substances that conventional treatment cannot remove — PFAS, inert COD, heavy metals, BTEX, dioxins, dyes — Klarwin integrates DiOx technology: Advanced Electrochemical Oxidation with diamond-coated electrodes. Modular, scalable, and effective against the most resistant pollutants.

Diamond-coated electrodes for advanced electrochemical oxidation
Targets: PFAS, persistent substances, inert COD, heavy metals, BTEX, dioxins
Also effective against: dyes, caustic wastewater, pharmaceutical residues
Modular and scalable design
Complementary to conventional tertiary treatment (UV, ozone, carbon)

Sludge Management

Complete sludge processing — from thickening through dewatering to final disposal preparation. CE-marked equipment manufactured to European standards.

Thickener — solid-liquid separation, 1mm slit size
Screw press — 3 dehydration zones: thickening, filtration, compression
Applications: primary, secondary and mixed municipal sludge, DAF sludge, digestate
Materials: stainless steel standard, duplex, super duplex, epoxy coating
Service team — video call support
Sludge thickener — disc thickening equipment for sludge management
Water reuse — treated wastewater for irrigation and industrial applications

Water Reuse

Tertiary wastewater treatment is the final stage of the treatment process, aimed at removing residual contaminants such as nutrients, heavy metals and micropollutants, to reach the standards required for water reuse.

Main applications — agricultural irrigation, industrial processes and other non-potable uses, safe source from tertiary treatment
Agricultural irrigation — residual nutrients contribute to soil fertilization, reducing the need for chemical fertilizers
Advanced technologies — ultrafiltration and reverse osmosis, high-quality water for sensitive industrial applications
Urban green spaces — irrigation of parks and golf courses, preserving drinking water resources
Pathogens and emerging pollutants — removal through UV disinfection and chemical oxidation, including pharmaceutical residues
Industrial reuse — equipment cooling, car washes and other non-potable uses, reducing costs and fresh water consumption
Aquifer recharge — preventing depletion of underground reserves and combating salinization in coastal areas
Additional pre-treatment — for sensitive applications, complete elimination of residual pollutant risks
Sustainable management — reducing pressure on natural resources and supporting adaptation to climate change
