Accreditation vs Certification

Product Overview
Kapwell Nut Shell Filters are designed to deliver effective filtration performance in all climates while maintaining cost efficiency. Our equipment is UKCA / CE marked and ATEX certified, compliant with the latest applicable ASME, API, DNV, and ABS standards.
Kapwell Nut Shell Filters utilize natural nut shells as a filtration medium, providing exceptional solids separation while minimizing pressure drop. The design accommodates the rigorous demands of the upstream process, ensuring optimal performance.
To achieve maximum filtration efficacy, operational parameters such as differential pressures and flow rates are utilized to determine the ideal configuration of the filter system. The selection of the nut shell filter, in terms of size and type, is influenced by factors including the nature of the fluid being processed and the specific contaminants to be removed.

Applications

Oil and Gas Industry
Nut shell filters are widely used for treating produced water in oil and gas operations. They effectively remove oil and suspended solids from water, ensuring compliance with environmental standards. Their high efficiency makes them ideal for offshore and onshore facilities.

Paper Mills
Nut shell filters are applied in paper mills to treat water contaminated with oil and suspended solids from machinery and process streams. They help maintain the water quality required for production while reducing water consumption and operational costs.

Mining Industry
In mining operations, nut shell filters treat water contaminated with oil and solids from machinery and processes. They help in maintaining water quality for reuse, lowering disposal costs, and protecting the environment from harmful discharges.

Power Plants
These filters are used in power plants to treat cooling water and wastewater. By efficiently removing oil and suspended solids, they prevent system fouling, extend equipment life, and help meet stringent water quality standards.

Petrochemical Plants
Nut shell filters are essential for treating process water contaminated with oil and particles. They provide an efficient solution for oil-water separation, minimizing the environmental impact and ensuring clean water for recirculation or discharge.

Food Processing Plants
In food processing, nut shell filters are used to treat wastewater containing oil, grease, and solids from production lines. Their ability to efficiently clean water ensures it can be reused or safely discharged, helping facilities meet environmental standards.
