Solids from Liquids

Filtration and Separation of
Solids from Liquids

Sludge Separator Skid

SERIES FS300

KD’s advanced sludge separator 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.

Vertical Pressure Leaf Filter Skid

SERIES FS400

KD’s Vertical Pressure Leaf Filter Skid is designed and equiped with a DE mixing tank and pneumatic control system to perform an effective filtration job. The KD’s pressure leaf filters are special designed with washing arrangement for washing the cake of the filter and extra large filtration area. This makes it possible to filter fluids with high dirt loads even at high flow rates. For slurry discharge the series FS400 is provided with a sluice header which is driven by a Pneumatic Actuator. The sluice header is equipped with flat water spray nozzle at 3.5 bar fresh water pressure. Cleaning the filter leaves can be done without opening the filter vessel.

Automatic Filtration Skid

SERIES FS500

KD is specialized in the design and fabrication of self-cleaning filtration skids. The filter element is an automatic strainer made of wire (V-shaped profile) welded on support pins; the space between the wire determines the micron rating. Continuous cleaning is carried out either by external scraping (the strainer is rotating and the vertical scrapers are fixed) or by internal brushing (the strainer is fixed and the helical brush is rotating). Impurities are directed toward the bottom of the filter and are removed through regular draining with manual or automatic valve. KD series FS500 ATEX, automatic strainer allows filtration of low to medium viscosity fluids and is ideal to filter a wide variety of products for applications in petrochemicals and oil & gas industry.

Dual Vessel Cartridge Filter Unit

SERIES FS600

The SERIES FS600 filtration skids are designed to filter particulate from liquids. The dual vessel cartridge filter 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.

Duplex High Flow Filtration Skid

SERIES FS610

The SERIES FS610 filtration skids are designed to filter particulate from liquids with high flow rates. The duplex filtration skids 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.

Coalescing Filtration Skid

SERIES FS710

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 FS710 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.

Mobile Pump Skid

SERIES MPS

KD’s series air driven pump skids and dieselmotor lobes rotary pump skids are mounted on a carbon steel stationary offshore proof DNV 2.7.1 frame. The dieselmotor pump skids come complete with self priming positive displacement liquid transfer pump. KD's Mobile Diesel Pump Skid is suitable for pumping any fluid, such as muds, pastes, and thick liquids in general, even when containing solids. Suitable for industrial, offshore and oilfield applications. Flow up to 2.400 l/min (144 m3/h) max pressure 5 bar. The series Mobile Diesel Pump Skid is designed for easy and reliable operation. The Dieselmotor is designed with a Lobes rotary pump, NBR lobes, complete with suction and discharge collector and complies to the actual rules for emission CO2.

Mobile Vacuüm Skid

SERIES VU4000

KD offers the VU4000 and VU6000 offshore mud vacuum units to clear drippings and spillages of daily drill floor operations. Our vacuum unit collects, stores and moves drilled cuttings within a totally enclosed environment, minimizing spills and contamination. The unit can be moved from one location to another in a minimal amount of time and minimizes the amount of floor space required for operation. Further, the unit does not interrupt the drilling operation. The pump with superb performance and high reliability is connected to a robust frame and vacuum tank with adequate capacity.

Overflow screen (hydraulic)

SERIES OS520

The KD International – CSO Screen Series OS520 ensures high Performance Screening at Overflows Weirs. The OS520 Screen is a simple and robust CSO Screen. It is designed to prevent the discharge of Floating, suspended, non biodegradable, and solid material. The Screenings and solids are retained within the flow for later removal at the inlet works of the wastewater Treatment plant. The Screen is manufactured from perforated stainless steel plates, which is the most effective solide Retention Screen. It is kept clean by using a pump that evacuates by suction force the accumulated debris from the Screen. The Screening debris ist pumped away and forwarded towards the waste water treatment plant.

Lamella Baffle (static)

SERIES OS510

Coarse solids can be discharged into the pre-clarifier in the form of suspended or floating matter during the relief process. In order to prevent this, relief structures were equipped with baffles which were given the task of retaining floating matter (e.g. oils and greases) and solid matter (e.g. sanitary products such as toilet paper, sanitary towels, etc.). The modern, environmentally friendly operation of a sewer system should aim at retaining these residues according to the current state of the art in as far as possible. The KD lamella baffle, Series OS510 is used for the targeted retention of floating matter in combined sewerage systems/ storm water systems without external energy. A lamella-like arrangement of baffle plates prevents the discharge of solid matter over the threshold into the pre-clarifier. A hydraulically specified arrangement and inclination of lamellas shaped specifically for this purpose ensures that floating matter described herein above is retained efficiently.
