Challenges We Solve for Industrial Manufacturers

Meeting High Purity and Process Water Standards

FILTEC provides industrial water purification systems that meet the strict purity requirements of electronics, pharmaceutical, and chemical manufacturing processes. 

Reducing Water Use and Discharge Volumes

Our water reuse and recycling systems help manufacturers recover water from rinse, cooling, and process streams—lowering intake and reducing discharge volumes.

Managing High-Strength and Variable Wastewater

We design industrial wastewater treatment systems to handle suspended solids, heavy metals, BOD/COD, and other site-specific challenges—ensuring environmental compliance.

Protecting Boilers and Cooling Systems

FILTEC supplies boiler feed water treatment and cooling tower water treatment systems that reduce scaling, corrosion, and system fouling—improving operational lifespan.

Maintaining Compliance with Trade Waste Limits

Our systems are engineered to meet discharge consents and local council requirements—supporting trade waste compliance across multiple industry types.

Addressing Complex Contaminants and By-products

We provide targeted treatment for colour, odour, oils, and grease—helping manufacturers manage niche contaminants common in industrial wastewater. 

Scaling with Production Growth and Site Expansion

FILTEC delivers modular and expandable industrial water treatment solutions—ensuring water systems scale with future site upgrades and increased throughput.

Supporting Sustainable Manufacturing Goals

Our solutions help manufacturers reduce water consumption, reuse wastewater, and minimise environmental footprint—contributing to broader ESG and sustainability targets.

High Purity & Ultrapure Water Systems

FILTEC designs high purity and ultrapure water systems for industrial applications that demand consistent, low-conductivity water. These systems use advanced filtration and polishing stages to meet the quality needs of electronics, chemical, and pharmaceutical manufacturing—ensuring product integrity and regulatory compliance across sensitive industrial processes.

Process Water Treatment

Our process water treatment systems remove particulates, organics, and minerals that could affect product quality or damage equipment. FILTEC works with manufacturers to treat process water used in rinsing, cooling, or ingredient preparation—helping maintain operational consistency, extend equipment life, and protect critical production workflows.

Boiler Feed & Cooling Tower Water Treatment

FILTEC provides boiler feed water treatment and cooling tower water treatment systems that reduce scaling, corrosion, and fouling. By removing hardness, silica, and contaminants, we help protect heat exchangers, steam boilers, and chillers—improving energy efficiency and reducing maintenance in industrial facilities.

Wastewater Treatment & Trade Waste Compliance

We deliver wastewater systems that treat high-strength industrial effluent to meet trade waste limits. Our solutions remove solids, BOD/COD, heavy metals, and specific chemicals—ensuring your site meets environmental discharge standards and maintains compliance with trade waste agreements and regulatory consents.

Water Reuse & Recycling Systems

Our water recycling systems treat wastewater for reuse in non-potable applications such as washdown, cooling, or utility supply. These systems reduce reliance on freshwater sources, lower operating costs, and support sustainable manufacturing initiatives across industrial production sites.

Heavy Metal Removal

FILTEC designs and installs treatment systems that remove heavy metals such as lead, zinc, copper, and chromium. Using chemical precipitation, filtration, and ion exchange, we help manufacturers comply with discharge regulations and protect receiving environments from long-term contamination.

Industrial water purification and Trade Waste Compliance

Colour, COD/BOD, and TSS Reduction

We provide oxidation, clarification, and filtration technologies to reduce colour, chemical oxygen demand (COD), biological oxygen demand (BOD), and total suspended solids (TSS). These systems are used in pulp, textile, chemical, and other industries where effluent quality must meet strict visual and analytical parameters.

Oil and Grease Separation

FILTEC supplies oil and grease separation systems for manufacturing sites where lubricants, surfactants, or fats are present in process or washdown water. Our solutions include coalescing plate separators, dissolved air flotation (DAF), and skimming systems—ensuring effluent quality and protecting downstream treatment stages.
