Cleaner Water, Stronger Fibre, Smoother Production
Advanced Solutions for Fibre Processing and Water Management
Cube Black provides a comprehensive range of separation, filtration, and materials handling solutions tailored to the pulp and paper industry. Solid–liquid separation plays a vital role at every stage—from raw material pulping and bleaching to process water treatment and wastewater recovery.
Our engineered systems help optimise fibre recovery, reduce water consumption, and remove contaminants—ensuring consistent product quality while supporting environmental compliance. Whether you’re clarifying process water, treating effluents, or extracting reusable fibres, our solutions are built for efficiency and reliability.
We deliver turnkey support, including equipment design, water testing, manufacturing, installation, and commissioning. With refurbishment and upgrade options also available, Cube Black offers cost-effective, sustainable solutions that meet both current and future industry demands.
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

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.
