  1. General Water Treatment Q & A

    Which type of filter do I need?

    Nearly every water source can be improved with the right water filtration system. Even if your water is under tight federal oversight, it contains substances that cause unpleasant taste and odors.

  2. Booster Pump Questions & Answers - Residential and Light Commercial Reverse Osmosis

    Do I need a booster pump?

    If you're running city water through your RO system, you probably don't need an additional booster pump. Municipalities try their best to maintain water pressure at individual homes at or above 50 PSI, which is exactly what your residential undersink or countertop reverse osmosis membrane requires.

  4. Whole House Water Filtration: Cartridge or Backwash Tank Systems?

    Cartridge filter or backwash whole house filter

    What types of whole house water filtration systems are out there?

    Whole house water filters can be either cartridge based or tank based. They each feature different components that perform unique functions. Tank based filters also go by 'backwash' or 'self-clean' filters since they clean and reuse the filter media by pumping water backwards through the filter bed and flushing trapped contaminants down a drain.

    Cartridge based filters are much cheaper upfront, easier to install and does not require much space. They do not require a drain connection and can even

  5. Carbon Basics

      Carbon Basics

    • Granular activated carbon is commonly used for reducing organics and residual disinfectants from water supplies. This im-proves taste and protects water treatment components such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling. Typical surface area for activated carbon is approximately 1,000 square meters per gram (m2/gm). However, different raw materials produce different types of activated carbon varying in hardness, density, pore and particle sizes, surface areas, extractables, ash and pH. These differences in properties make certain car-bons preferable over others in different applications. The two principal mechanisms by which activated carbon removes con-taminants from water are adsorption and catalytic reduction. Organics are removed by adsorption and residual disinfectants are removed by catalytic reduction.

  8. Backwash/Whole House Filter Questions & Answers

    How often should filters be backwashed?

    As filtration proceeds, the void areas in the medium become filled with particles removed from the water, resulting in pressure drop from the outlet. Flow rates through the filter medium decreases until it becomes insufficient to meet the demand. A partially clogged filter bed also results in deteriorated water quality. At WECO we prefer backwashing done at least every 4-7 days at 10 gpm/sq.ft and the whole house systems are pre-programed for the self-cleaning cycle to occur at 2.00 AM.

    One way to make the when-to-backwash decision is to install pressure gauges before and after the filter. Backwashing should be performed when the pressure drop reaches a pre-determined maximum value (typically 15 PSI for whole house systems). Backwash the system on demand by pressing the Regeneration

  9. Why to speak with a water treatment specialist and how to determine what water treatment equipment is best for you

    Why do I need a water treatment specialist? Wont some equipment from the store work just fine?

    When it comes to water treatment there is no turnkey solution that works for all water sources. The water that is supplied changes throughout the planet while also changing with the seasons. So there may be a setup in New York that works really well on their water source but it might not work well in California. Each water treatment system needs to be adjusted for based on the water that will be processed within the system. So if we want to find the perfect equipment to process our water we need to find a way to figure out what’s in the water. This is where a water sample should be obtained and sent in for analysis.

  10. Silica Treatment in Residential Applications

    Resedential Silica Treatment

    This article is going to explore silica in water and how to treat the water for silica removal. Silicon dioxide is one of the most abundant compounds on earth and having such a high amount of it makes for no surprise that nearly all water contains colloidal and dissolved silica in solution unless it is treated. Silica is a glassy mineral substance that comes in a variety of forms. It is problematic because of its tendency to form deposits and scale. There are studies done by quite a few sources as to the effect of silica exposure for long periods of time but that is for another topic.
