High Capacity Filter Bag

 Press Releases

  • No mountain too high, no water to deep for Dutch Filtration

    Dutch Filtration has designed and built a filtration system on behalf of one of the world’s largest Oil & Gas service companies. With our experienced engineering department, we design products of the highest quality.

    Filterpackage for filtration of Completion Fluids

    The uniqueness of this filtration system is that it will be the largest filter press for the offshore industry in the world. This high flow filter package is designed for filtration of well completion fluids at high rates for (ultra) deep offshore operations.
    The customer, headquartered in Houston Texas, wanted the largest offshore filter system for the filtration of completion fluids.

    These salty and heavy fluids are used to clean out the wellbore to maximize oil and gas production. The system will be deployed in the Gulf of Mexico in ultra deep water. The filter units are placed on large floating drilling platforms in water depths of more than 1.5 km and the drilling goes up to several kilometers into the seabed. Due to the great depths, large volumes of clean ‘completion fluids’ are required at a flow rate of more than 300 m3/hr (>32 BPM). The water can contain up to 0.5% suspended dirt particles and be as black as coffee. Our filter system removes all particles from the water up to 2 microns with an efficiency of 99.98% and after filtration the water is as clear as tap water.

    Stackable slurry skid with dual vessel filter unit

    The filter press comes with a stackable slurry skid and a dosing unit for filter aid. The large working platform can be accessed with a ladder this entrance has a security gate. Everything is designed for use on an offshore drilling platform and meets the strictest standards. All pipework, pressure vessels, tanks are made of stainless steel for corrosion resistance. Everything is very robust and easy to operate and maintain. The entire design was carried out by our engineers and the complete system was inspected and stamped by Lloyds to DNV2.7-1 / ISO10855. The system is equipped with several innovative details that make the system work safely, quickly and efficiently. Among other things that make this happen are:

    Semi-automatic plate shifter Filter Press

    A semi-automatic plate shifter which shifts the filter plates of the filter one by one for cleaning. This drastically eases the operations, lightens the manual labor and ensures a safer work method.

    Semi-automatic powder dosing system for Diatomaceous Earth dosing

    A semi-automatic powder dosing system. Instead of manually cutting open to bags with filter aid and dosing manually, the new system pumps (air driven) the filter aid from a big bag holding tank, dust-free and mixed in the tanks on the stackable slurry skid.

    Quick opening Closure

    The filter housings (for filter elements) are fitted with our proprietary Rudi Quick Opening/Closures (designed by Ruud Wolthuis). This allows for very quick and safe opening and closing of the filter vessels without the use of any hand tools.

  • With our high capacity filter basket & bag the filtration surface area is increased by 70%. By placing this filter bag, you can take a smaller and cheaper filter housing, but still have the desired flow rate and dirt holding capacity. This increased dirt holding capacity extends the service life of the filter bag. The liquid enters the filter bag and then passes through the outer surface and through the central core, doubling the flow rate.

    The volume of retained liquid is reduced by 30% compared to a standard filter bag, reducing the removal weight, and wasting less product.

    Application membrane prefiltration with high capacity filter bags

    Our customer has 4-off Reverse Osmosis (RO) units protected by 4 x 2 single bag filter housings with standard length #2 polypropylene filter bags @ 10 microns, 24/7.

    The life of these filter bags was very short, which meant that the bags had to be changed out several times a day, resulting in a usage of 32 filter bags per day. (11500 pieces/year ~ €70K/year).

    In addition to the cost of the filter bags, the cost of downtime and maintenance was also very high, as the filter bags had to be replaced even during the night shift.

    The first step was to replace with our high capacity basket and polypropylene bags in the existing single filter housings. This resulted in changing the filter bags twice a day and using 16 bags.

    The cost of the high capacity basket and polypropylene filter bags was recovered within 2 months and after that the savings on the filter bags was € 30,- /day (€ 11.500,- / year). This cost reduction was only material, the cost reduction on maintenance was 3 times higher. This relatively simple conversion using the existing bag filter housings saved the customer ~ € 30K per year.

    Single bag replaced with multi bag housing

    This was only the first step!

    The operators still had to change the filter bags almost every night because the bags were clogged, and the RO plant was continuously backwashing what also resulted in a higher CIP frequency.

    This was a big problem for the operators and the cost of personnel during the night was very high.

    We were convinced that if we replaced the single bag filters with our DFVB600 multi bag housing each with 4x high capacity baskets and polypropylene filter bags, we would extend the life of the filter bags and therefore greatly reduce the need to replace the filter bags. The theory behind this was to increase the total filter area by doubling the number of filter bags resulting in a much lower flux and this results in an increase in filter bag life of up to 4 times or more. To convince the customer we installed our rental Dual Vessel Bag filter unit and conducted a test for several weeks.

    Return on investment realized within the first year with our high capacity filter bag

    Our customer ordered 4 pieces of combination bag/cartridge filter housings (DFVCB600-50-40-4-2-4), and these were installed in front of the 4x RO units. In addition to the high capacity basket and polypropylene bags, the customer also uses our Twistflow nominal rated string wound filter cartridges which result in even longer life and less maintenance (change outs).

    The ROI of this project was realized within the first year. Of course, for us as a supplier of filter consumables not the most profitable, but for the customer a significant reduction in operational costs.

    We are convinced that offering the best solution for the customer is the only solution.

    What is a Filter Press

    A Filter Press is used for liquid/solid separation. It’s called a Filter Press because pressure is used to separate the liquids and the solids. The Filter Press consists of a set of vertical recessed plates pressed by each other through hydraulic cylinder. A slurry is pumped into a Filter Press and under pressure water flows through the plates and build up filter cake. Each filter plate must withstand the internal pressure developed by the sludge pumped into the Filter Press. Therefor the it must withstand high pressures. The main components of a Filter Press include the filter plates with filter cloths, the frame, piping and valves. The working principle of a filter press is based on slurry solids (mostly Diatomaceous Earth) building up on the filter cloth forming the filter cake. The slurry is mixed in a slurry tank and is pumped into the Filter Press. The wastewater is then pumped into it and passes through the filter cake and cloths, the filtered water exits the filter plates through the outlet. The solids will be built up within the chambers until they are full and the cycle is completed. The filter cake must be released and filter cloth must be cleaned.

    Filtration time depends on:

    • Sludge concentration
    • Specific resistance
    • Cake thickness
    • Compressibility coefficient

    The first filter press was built around the 1800’s and then it was called a “plate and frame” filter, sometimes people still use this term.

    Filter Press Applications

    Because the size of a filter press can vary from very small (lab-scale) to very large Filter Presses (250m2) filter presses can be used in a broad spectrum of applications such as;

    • Completion Fluids
    • Work-over Fluids
    • Gravel-pack Fluids
    • Wellbore Clean-up fluids
    • Food and Beverage
    • (Bio) Diesel
    • Surface Water Intake
    • Process Water
    • Frac Fluids
    • Wastewater
