Turning Wastewater Into a Working Resource—Efficiently
High-Performance Systems for Water Purification and Waste Treatment
Cube Black delivers a wide range of standard and skid-mounted containerised solutions for municipal and industrial water treatment. Our advanced separation, filtration, and materials handling systems are designed to meet the rigorous demands of water purification and wastewater recovery.
At the core is solid–liquid separation—essential for removing contaminants, reducing sludge, and ensuring water meets strict safety and quality standards. From pre-treatment screening and sludge dewatering to advanced membrane filtration for potable water, our integrated systems optimise every stage of the process.
Whether it’s purifying municipal drinking water or treating complex industrial effluents, we provide full-cycle support—from design and engineering to installation, commissioning, and equipment upgrades. With engineered clarifiers, thickeners, filtration systems and other relevant products we deliver efficient, sustainable, and cost-effective solutions that ensure long-term reliability and compliance.
Relevant Products
High Rate Thickener
Thickeners are used in continuous process applications where solid-liquid separation by sedimentation is involved. In some applications, Thickeners recover valuable solids, while in others, liquids are recovered.

Clarifier
Clarification is the process in which solids are removed from liquid. The primary function of a Clarifier is to produce a clear or solid-free liquid, rather than a concentrate. Our Clarifiers are designed to produce a clear liquid overflow and high-density underflow.

Flocculant Plant
Flocculants are polymers that promote flocculation by the formation of bridges between themselves and thus become suspended particles. Designed for a set consumption rate with various strengths, which results in successful inline dilution using inline static mixers

Reagent Plants
Cube Black offers a selection of Reagent Plants with various bulk storage options. Our Reagent Plants are available in a range of sizes based on volumetric flow, retention, and hydration time to meet the process demand.

Inclinded Plate Settlers
An Inclined Plate Settler (IPS) is a type of settler designated to remove particulates from liquids. Inclined plates provide a large effective settling area for a small footprint. Inclined Plate Settlers decrease the settlement rate in a faster timespan.

DAF System
Our DAF systems are specially designed to remove or reduce suspended solids, fats, oils and greases (FOG), biological oxygen demand (BOD), chemical oxygen demand (COD) and volatile organic carbons (VOCs)

Reverse Osmosis
Our RO Plants are designed to be robust and stand-alone units for a wide range of applications where high-quality equipment for water is required. Our plants are compact and easy to install.

Dual Media Filters
The term media filter, as applied to water treatment, refers to the removal of suspended solids from water. In most cases it is the last stage in the pretreatment of water for removal of un dissolved impurities prior to treatment by Ion Exchange or by Reverse Osmosis.

Aeration Systems
Aeration is used in water treatment as a pretreatment in the process of removing iron and hydrogen sulphide (rotten egg smell) from water. It reduces hydrogen sulfide to elemental sulphur, which is easily removed from water process systems.
