The service you need, we have it

  • Let DESIGNH2O help you choose the best water/waste water treatment for your application.  Most water treatment projects begin with the planning and conceptual design to determine the best treatment process for a specific application, our team will evaluate each proposed treatment/design alternatives and develop a preliminary design and cost estimate based on the information supplied by each potential supplier and help you make the best possible decision before you buy.

  • The feed water, depending on its source, may contain various concentrations of suspended solids and dissolved matter. Suspended solids may consist of inorganic particles, colloids and biological debris such as microorganisms, algae and deposit that can settle on the membrane surface, obstructing the feed channels and creating a pressure drop across the membranes.  The objective of the feed water pretreatment process is to prevent the suspended particles from reaching the RO membranes.
Depending on the raw water quality, the pretreatment process may consist of all or some of the following treatment steps:
	Suspended particles removal
	Biological pre-treatment
	Chemical pre-treatment.

  • Multimedia Filtration
Multimedia filters consist of three layers of media: anthracite, sand and garnet. The media are often chosen based on their distinct differences in densities.
The media layers are arranged in such a way that the layer with the finest level of filtration is further down, followed by the sand layer and finally the coarse layer which is the anthracite at the top of the media in the filter.  A multimedia filter can remove particles down to 10-20 microns.
Over time the buildup of suspended particles in the media will cause the differential pressure across the filter to increase, when the differential pressure gets to 10 psi above the normal operating pressure of the filter, (i.e.  when is clean), it is at that point the media will need to be backwashed.  The backwash process consists in reversing the flow through the filter to loosen the media and remove the dirt through the top of the tank.

  • For Organic matter, Pesticides, and Herbicides, the standard treatment, and in most cases the only treatment recommended, is activated carbon. Carbon filters remove chemicals by the process of absorption.  Carbon attracts certain chemicals at the molecular level much in the same way a magnet attracts and holds metal fillings. When the surfaces are full, the filter must be backwashed.
Timely media backwash is very important, because carbon has different absorption capacity for different contaminants. Most the time chlorine removal tests will determine when the carbon media should be renewed. This works only if chlorine removal is all what is expected from the filter. Most carbon filters will begin to 'leak' other chemicals long before they begin to allow chlorine to pass through it.

  • Contrary to the way many people think, membranes are not the solution to every water problem, pre-treatment plays a significant role ensuring that the membranes do what they are there to do, a good pre-treatment design is as important as the membrane design and they complement each other. Selection of the proper chemical pre-treatment will maximize the efficiency and life of the membranes.
DESIGNH2O works with the leading chemical manufacturers in the world and uses the latest software to determine the best chemical pretreatment for membranes, our experience in process design will ensure that your membranes are protected and your chemical pre-treatment is optimized.

Technology is key to the water treatment process and you can find it in DesignH2O Inc.


  • The most common configuration for Ultrafiltration (UF) membranes is the hollow fiber construction. The filtration spectrum below (Fig 1) shows the approximated level of filtration for UF membranes to be between 1000 to 50 Angstroms, at this level of filtration, UF membranes will remove all fine silt, turbidity, bacteria and viruses, as well as chlorine-resistant organisms such as Cryptosporidium and Giardia.
Due to the high fluxes and low pressures of operation (<60 psi), UF has become the preferred technology to produce potable water and process water, and it is used in the pre-treatment process of large Seawater Reverse Osmosis (SWRO) plants.
Hollow fiber ultrafiltration membrane technology also has proven to be an excellent large-scale treatment method for surface water treatment, polishing effluent of wastewater treatment plants, and groundwater projects with suspended solid levels of up to 100 to 200 mg/L.
Ultrafiltration membranes are also produced in flat sheet, tubular, spirals and of course hollow fiber, each configuration has specific uses and applications.

  • Nanofiltration (NF) membranes function similar to reverse osmosis membranes, but they target ions located between 100 and 10 Angstrom range in the filtration spectrum, such as sugars and dyes, however most of the monovalent ions such as sodium (Na) and chlorides (Cl) will only be removed between 70 and 85%.
NF membranes are widely used in the dairy industry for the concentration of lactose and cheese whey; also NF membranes are used in the dairy and beverage industry to reclaim spent caustic soda (NaOH) cleaning solution allowing it to be reused many times over. In the water industry NF membranes are used for hardness reduction (in place of softeners), pesticides and color (dye) removal from water streams.
NF membranes typical operating pressures are between 120 and 600 psi (8 - 41 bar).

  • Reverse Osmosis (RO) is a high-pressure process that retains 99+% of all dissolved particles in water, while letting substances with MW smaller than 50 Angstroms pass through.
One of its most common applications is seawater desalination, in which pure water is produced from a highly saline feed stream; also some of its other applications include the concentration of cheese whey and fruit juice, ice making, car wash reclamation, wastewater volume reduction, ultrapure water production with a second pass, etc.
RO typical operating pressures are between 100 and 850 psi (21 and 59 bar), but may reach 1200 psi (83 bar) for seawater applications.
