Water is our most important
Natural Resource

Emulsion Destabilization Skid


The presence of surfactants in oil and gas waters can cause very stable emulsions, treating this water by the use of chemicals like coagulants in combination with flocculants  requires chemicals handling & storage, specialized personnel and extra transports. The traditional management of oil and gas water is costly and wasteful. Series SWANOX, Treatment Skid, utilizes alternative force to drive chemical reactions in a solution, suspension, or emulsion. The treatment process is very similar to normal chemical coagulation, the difference is that it uses an alternative energy force.

Coalescing Filtration Skid


With an unique combination of our Coalescing plate technology inside a pressurized separator as crucial pre-separation stage upstream of (2) polishing vessels the series PW-100 is able to remove suspended solids and both free and non/emulsified hydrocarbons. The combination of technologies makes the system unique in his kind, simple, robust and operator friendly. The high efficient pressurized pre-separation stage allows the waste water to be treated continuously even when there are slugs present. Depending on the type of water the operator can decide to use KD’s granular Absorption Media Cartridges for the removal of total petroleum hydrocarbons from water.

Dual Vessel Absorption Cartridge Unit


The SERIES FS700 filtration skids are designed to filter particulate from liquids and in addition can be converted to remove hydrocarbons from liquids by using KD’s world’s leading granular Absorption Media Cartridges for the removal of total petroleum hydrocarbons from water. The Dual Vessel Absorption cartridge units are designed to be a portable complete filtration system and can be easily into service with little more than upstream and downstream connections being made. The filtration skid is designed and build to process specifics for the required flows and micron retain age. By Maintaining absolute fluid cleanliness, end- users can dramatically increase the life of critical wear components on rotational equipment, minimizing downtime and maximizing profitability. The filtration skids are offshore proof and equipped with all necessay valves, safety features and allows operators to simultaneously filter with one vessel and change out cartridges in the other vessel. All according to the latest design codes.

Advanced Sludge Removal


KD’s advanced sludge removal system performed a very useful function in oil & gas field for removing solids from fluids without using energy or using rotating parts. Due to the unique design large sludge particles would settle and could be removed from the process fluid by a dedicated drain system. The bottom of the system should be sloped to facilitate optimal functioning and self cleaning. The advanced sludge removal system should not be agitated and should overflow into the next compartment. The system can be easily installed inline with other KD treatment systems.

Mobile Oily Water Separator


KD's Oil Water Separator is a gravity separation device designed by using Stokes Law to define the rise velocity of oil droplets based on their density and size. The design of the separator is based on the specific gravity difference between the oil and the wastewater. KD International offers an extensive line of Mobile Oily Water Separators that bring both efficiency and low maintenance. With some unique innovations KD´s Oil Water Separators, make the design highly efficient, easy to maintain and suitable for the demand of each individual client and application. Our unique design and technology makes KD's Oil Water Separators the preferred choice for the following applications; (1) Oil Spills on seas / oceans (2) Oil Spills on rivers / lakes (3) Oil Spills in groundwater (4) Oil Spills in harbours (5) process waters (6) overboard water.

Offshore Seawater (RO) Desalination Skid

series OSD-RO

In close cooperation with one of our partners we concentrate on membrane separation processes, predominantly Reverse Osmosis (RO), Nano-Filtration (NF) and Ultra-Filtration (UF), to treat water for drinking, process and industrial purposes. Our experience covers a wide range of plant types, from low pressure RO for the treatment of tap water through to high pressure seawater RO desalination for fresh water production on-board ships on offshore platforms and on land.

Containerised (RO) Desalination

series CD-RO

We are able to manufacture plants of all sizes, from 1 m3/d package desalination plant through to custom built packages as large as 2,000 m3/d installed on-site. Plants can also be offered designed and constructed inside standard ISO containers or trailer mounted, thereby allowing quick hook-up and commissioning. Our Services has more than ten engineers with offshore survival certification – this enables us to mobilise at short notice to provide offshore servicing and technical support.
